No - we are over - I will chase and re-order...
Gannet 15cc four stroke
Any news yet...?
I'm guessing that nothing arrived...?
Alas, working. That usually takes me out of everything for several months. I strongly suspect that another ESC order will be needed...
At this moment it's 04:01 Peter.
Hi Peter, the models are a foam model from Durafly which were bought from Hobby king about 5 yrs ago in a kit form which had to be all glued together. Doing it that way you had to buy all the extra bits separately (there was another option as an ARF but it was underpowered)
One has fixed gear,camera, lights, carbon fiber rods in the wings and tail booms (Both have that strengthening) as in original form, the tail booms were so flexible that when the model was pulled up in a fast dive the tail booms would bend down, - effectively giving down tail plane and crashing if too low) There were lots of videos when they first came out, wallowing up and down as the operator went from up elevator to down elevator (up tail plane) and back, trying to correct it (usually ending in a crash). Only way to stop it was to cut the throttle.
They have now corrected the fault but it took them a few years. Also a problem was the COG shown in the instructions, which was miles out. Crashed the first one (orange) about 5 times before finding the right balance, (no help from Hobby King though for anyone! Now both fly perfectly and are real 'floaters' and sound really good for electrics. I've also cut intakes in the fuse tops and enlarged the side intakes, as the std flow was a bit restricted.
The Silver one has electric retracts which I modified, as the models had provision for retracts, fixed gear or no gear, but the retracts worked inwards from out in the wing. I re- cut the wings to take the retracts around the correct way, and shortened the legs which were stupidly long, (took about 35% off) Don't know why they didn't design them like that in the first place as it was easy to do and the wheels (larger than std) come up to 1mm under the wing top. I'll try to put up a vid sometime.
We had the twin seat trainer versions here as well, and the last ones still flying here in displays are both trainers from memory. There is also a Venom here still I think (had a wheels up flameout on takeoff from Ardmore Airfield, South of Auckland a few years back, - vid on You Tube ) which should have been fixed by now, Don't think they wrote it off, ended up going through a fence and into a paddock.

Yup - used them in my OSA. Any ESCs yet?

Hi Peter, a pic of my 2 vampires. Only Durafly foam but with a lot of mods, (camera, retracts-modded to work the right way- outwards, landing lights, rudders, carbon fibre wing and boom rods, nav lights etc. One has a 6 blade fan, the other a 10 blade. Orange one (5 blade) flys at 65mph, silver one (10 blade) at around 75mph. One pic is a vid grab from the nose camera while flying behind a flock of geese.

Good to hear - they should be the second lot - the first lot turned up quite rapidly here. I'm more worried about the ESCs - long delivery times often mean that the seller just wants to sit on your money and refund it after a month without actually sending anything...
I am invariably forgetting to add clearances for points where there is an overlap or butt joint, and end up getting the tabs 1/8" out of position.. The nice thing about balsa is that you can then just glue an extra scrap of balsa on, sand it a bit and recover the situation.
I would expect your motors to turn up in a week or so. They turned up reliably and rapidly here. But we should keep an eye on the ESCs...

Ah, the motors! Yes, they turned up here a few days ago. I had made a mistake and not altered the default address......🤔😂 Sorry about that...
I immediately sent another purchase order to the suppliers. They should be turning up in a week or so.
The ESCs are a bit more of a concern. They should go to Barbera - but the long lead time makes me suspicious. We will wait until Oct, and if nothing happens I will reorder from a company with a more rapid delivery date.
I did a bit more on the corvette - it's so easy when you have a CNC cutter...

Hi Peter, I'll see how I go with time as I have a lot to do over summer (work on house etc $$$) and usually go out in the real boats whenever pos. Usually only do models over winter as it's mainly too wet to do much else. I'll have a think anyhow and see if I can come up with anything simple to make which will fit into the easy to build category and would look modern, (maybe a model of the 20ft Hartley flareline I built). Was thinking that would be next years project in 40" (1/6th scale).

I see your point - the Sea Princess seems fine with 1/16" skin and frames at 4" centres, but this is bigger still and currently has 5" centres. Perhaps 3/32" might be a compromise...?
I was going to trial commercial DIY wood hardener for this boat - a high-volume product should be cheaper and easier to source.
I'm sure that I can find roofing membrane locally here - though I would have thought it might be rather thick? Do you have a picture? Is it anything like this, for instance?

".....1/8 Balsa should be ok - providing you plank using it as well......"
Had been assuming that i would use 1/16" as per usual. Perhaps I should use 1/8" for the angled top half of each side - after all it's essentially part of the deck...

Actually, a day over! Naughty! But we now have two items...isn't purchasing from China fun?
I cut out the parts for the C01 stealth corvette hull on the CNC machine - here they are slotted together, though not glued. The jet drives looked a little big and powerful to me for a 28" hull, so I upped the LOA to 36". Perhaps that's a bit long for 1/8" balsa?

if we have nothing by end of play 3 Sep tell me and I'll start getting a resend...
Interesting to see the twin pump-jets - due tomorrow. Apparently been in the UK for a couple of weeks...??

Thanks - we will keep an eye open, and check again in a couple of weeks.
For reference, the maximum times specified for sending are:
Jets - 3 Sep
Servo test - 9 Sep
Motors - 27 Sep
ESCs - 11 Oct
As I said, things usually come earlier, and if you have to wait til the last date they are probably lost, and you have to get a resend!

"...wont ask what you are doing up a 4.30am.."
The enclosed photo will give an indication...
Your letter seems reasonable to me - the idea would be to start a conversation rather than to criticise a policy.
By now most of the item to ship to you should be arriving at your sisters. I find that if things are not going to be 'lost' they usually arrive fairly promptly - though one or two things will delay for a while.
Could you ask your sister if anything has arrived yet - and, if so, what? There was some confusion about ordering the motors and I was told they would go to her but I suspect they will end up with me...

Yes - they are different and complicated - but 4.30 on the morning in Athens is not the best time to explain...
Brushed ESCs are traditionally, and technically, separate from the motor. Brushless ESCs are an essential part of the motor operation, and they use software to energise the coils in the right sequence, so there can be quite a lot to set up.
Typically the ESCs need to know what the max and min tx pulse rates are, where the neutral point will be if you have reverse, do you want soft start or brake features, and a common feature for brushless - what kind of battery do you have and at what voltage do you want what kind of cut-off? This last is important for Lipo batteries which must not be completely run down.
Brushed ESCs usually make these choices by physical jumpers. Brushless one's usually have two methods - use a programming card or signal by using the Tx. Programming cards are usually specific to individual ESCs, so Tx signal is best to start with.
Tx signal works by connecting up the ESC to the receiver, powering up with the Tx typically on full throttle, then moving the throttle stick up and down in a fixed series of moves. The ESC will respond with musical tones or beeps as you signal the various settings....
This always causes problems. People don't realise that the ESC won't work out of the box - it needs to be set up first...

Hi fellow South African. Noticed your chat on MB site. I sail at Emmerentia dam. We do u live?
Never exactly MOD - as a civilian specialist we were in the officer's mess - in a headquarters where Admirals were 10 a penny... so I'm afraid that we were often rude to some very top brass.
I recall testing some of the comms network. We sent dummy messages to dummy ships, only one day one went out for real, of course... It read "Bollocks to the Captain of Ark Royal!".
Flag Officer Ark Royal sent a signal back asking if Northwood really wanted him to deliver it, and we were called in to be told that in future test messages were to read 'OPCON Test Message' (OPCON=Operational Control).
That worked for a while. Then another test message escaped - this one went out on the Whitehall TARE to 'All Embassies'. ... There was a 30 minute wait, then messages started arriving thick and fast to the FCO saying "What does OPCON Test Message mean - we can't find it in any of our code books."
We were called in again and told that in future test messages were to read "OPCON Test Message - No Action Necessary"......

The way I see it is that your sister will owe me £25 at some point - now, let's see what other useful little things we can add to the mix..
I started my career as a civilian programmer attached to MOD Navy creating their first integrated headquarters command and control system. That included things like war declaration and nuclear weapons release coding - and it was six months before I had any formal computer language training. So the Navy had the system during the mornings for operational use while we got tanked up in the Mess, and then we got it during the afternoon for development. Sometimes we did so much preparatory work during the morning that we couldn't walk straight . ..

I can stick a cheap servo tester in the mix - bring the cost up to a round £25. Handy for brushless if you've never used them before, because the ESCs have a complicated programming process...
Am suffering Heathrow at the moment. Do you have a servo tester? useful for testing kit like motors - otherwise you have to set up a tx/rx..
OK - purchases made. For your records these should be:
2 jet units - £13.26 - expected UK 22Aug-03Sep
2 motors - £7.12 - expected UK 27Aug-05Sep
2 ESCs - £5.02 - expected UK 02Sep-11Oct
Note that these are typical 'cheap Chinese'. So far I have found that they work fine - but I can't guarantee it. Also note that if they are coming they usually come within a few weeks - if your sister is waiting until the last day they will probably not come on the next day either! In that case you need to get in touch with me, because I will have to put a complaint in. Same for anything which arrives damaged.
The jet coupling comes with a small hole - you will have to drill it out to 3mm for those motors.
You don't actually need a credit card to get a Paypal account if you have a business. Paypal will happily create an account in the business name for you to accept payment into. To have an account which you can use to buy things with, however, you will need to provide details of a bank account

"...I am clueless on these things because of lack of exposure to them so would have to be advised by you on those ...Probably 4 times as expensive here..."
I am not an expert on ... anything, really! I just mess about, as I have been doing all my life...
With regard to brushless motors I have used them on my light EeZeBilts, and find that the cheapest ones seem to have quite enough power for these boats when run at 7.2v, which is quite a low voltage for them. That has an advantage in that I do not need to watercool anything. I am sure that you can get a lot more power out of these things, but you then need to match propellers properly, get the right cabling, cool properly, etc. I just overspec and underuse - saves knowing what I am doing!
For brushless motors you will need to specify a kV rating. You have come across this - it is the revs per volt. I use 7.2v batteries, and use motors around 1000 kV, giving an unloaded prop speed of 7200 revs. A 1400kV motor would run at around 10,000 revs on 7.2v. Do you have any preferences?
Incidentally, what are your problems in obtaining modelling items in South Africa? If it is postage, surely your sister posting items would hit the same problem? Or does she fly to visit you frequently? Are you able to set up a Paypal account from SA? It simply requires a credit card. If so, presumably you could buy items yourself off the UK Ebay and have them shipped to your sister direct?
One other thing. Delivery failures for the cheapest items, which I tend to buy, are very common. I suspect that there is some kind of scam going, whereby items are offered for sale cheap, nothing is sent, and the money is refunded after a month or so by Ebay. That means the trader has your money for a month, and he may even claim on insurance? I find that Ebay are happy to refund (so far), but it is annoying, and I would recommend against buying anything for a lot of money in this manner...

I use the cheapest items I can get away with - that is probably what a beginner will do!
Those are the commonest cheap motors - fine for something like the PT Boat. They come in many different KV ratings, so check that if you want to get any - I use 950-1400, typically 1000.
The cheapest escs seem to be these 30A ones, at between GBP 2-3 - https://www.ebay.co.uk/itm/30A-Brushless-Motor-Speed-Controller-ESC-Simonk-w-5V-3A-Multirotor-Helicopter/192953256023?hash=item2cece90857:g:WBwAAOSwmYZc2jY1

Can - yes, by definition the web is everywhere.
Will - who knows? I am likely to be very busy with non-modelling activities...
Incidentally, these cheap brushless bolt on easily to the waterjet - but the connector would need to be drilled out to 3mm to accept their shafts....

"..Hi Dodgy - could you do me a big favour - wanted two of those "jet sprayers" but they don't post to SA . (Very frustrating to say the least). Could I ask you to please buy them for me and I will get sister to recompense you when you let me know how much. Sister can get them to me..."
I have now received a single jet which I ordered to see what they were like. They are, of course, intended for mounting in a RTR, but they have a good flat plate around the hull entry point, so can be adapted for other use. Unfortunately no shaped rubber gaskets came with mine :( Output jet can easily be adjusted to allow for hull bottom tilt! No easy reversing bucket, however. Plastic is fairly stiff.
Do you want white or black plastic? And do you want them with a motor attached or not? I was going to use my own motors, and this one comes with a motor connector included. If you want a motor included, there are several you can choose from, but they seemed a bit expensive to me!
I suggest that you pick a specific ebay advert, then send it to me. If you want it to go to your sister's address I can simply pay for it and have it delivered straight to her - it's the one in Blackfield? If you want it delivered to me I will order it when I come back from Greece, as I don't want to get it undelivered and lost if Ii'm not here...
I've described what i feel about it - if you have any questions give a shout...

Not exactly - I have a son getting married, so I count this as work... 😊
No problem - but can you wait a couple of weeks? I have to be in Greece from 13th to 21st, and will not be able to receive parcels until after that time. There are lots on ebay - I don't think the supply will dry up. It seems that the factories which make ready-to-run craft are augmenting their profits by selling the various parts to the (small) model making community....
P.S. - we are dying of sunshine here - Britain is not designed for 100 F ...
I have it - kept failing to get it down over the afternoon until I went in without the security proxy on...
This is a real treasure trove. It would be great to spread it wider around contacts - if you think that would be acceptable?

That would be much appreciated Peter, sure I could make it work. Was thinking of trying to make the Seaplane Tender frames final shapes and positions so people could knock one up. I have the Model Boats mag full size (40") plan, elevation and frame profiles printed up from A4 to A0 paper which can be scaled to anything.
Be ok for people with a bit of building experience as you need to sort of correct as you go. I have pics to show general process/method etc should they be needed. I wouldn't get too carried away as there would be very few interested probably. So many people seem keen on fireboats for some reason.

Hi Peter, thought these pics might be of interest. I haven't changed it much in probably 18 yrs except for changing the ESC. Originally had a home made ESC made from a 12v voltage regulator kit with a servo attached to the pot (no reverse) then to an A/C ESC (no reverse) and now with a car ESC. pretty crude inside but it works, has nav and internal lights off dry cell battery packs operated by 2 switches (one on the bulkhead by the wheel and one under the mast)
The coamings come off in 3 pieces starting with the wheelhouse, then center with dinghy, then rear cabin (goes back on in reverse order with center tucking under rear cabin front edge and wheelhouse going over a dowel to position it over the center section. Front deck hatch is taken off by removing wheelhouse and pushing hatch up from underneath. Front cabin used for REC. The anchor is fully working as well.
A single removable top might have been a better idea, but I thought it would have been big lid to construct and more prone to warping. I'd like to make another Maiami sometime as mentioned but do it properly, as I have plenty of shafts motors, ESCs etc to use up, (need to get rid of a few of my 18 planes first though!) but still have a scratch built one to finish (not sure if it will fly,-bit of a guess at things just going off photos,-couldn't see what the wing looked like and only one prototype ever built) Be a 'hit the throttle and hope' effort!.
Must drag out the Model Boats mag and see if the Maiami drawing is worth blowing up for a plan, (think it has the frame profiles) Do you have any pics of yours as it was and now?

Hi Peter,
"and I've already got way too many"
For over a year I've had a 1:125 kit of an Akula II submarine lurking in the cellar.
Complete with static dive system and all the trimmings.
All this sub stuff chat on the site has prompted me to bring it to the top of the 'To Do' list, while all the chat and research is still fresh in the remaining grey cells😉
Just hauled it out and now I'm going through the How to assemble and operate book!
So I daren't look in your plans collection, much too dangerous 🤔

Though it is nice to hear about it, you have no need to 'clear it with me' first! I put the initial designs out in the clear knowledge that, once distributed, I would have no control or ownership of them. This is what the 'open source' philosophy is about - putting things out to improve humanity generally. You still keep your copyright - you can't renounce that - but you use it simply to stop people monopolising the designs in order to make profit.
This is not what commercial plan designers want to hear - so if this sort of thing were to take off you would find people like Glynn Guest becoming very unhappy.
By all means set up a thread and see what comes of it. People might be encouraged by the thought of having their plans up on the web? But it will be a lot of work if people don't provide computer-readable data...

Thanks for the info Peter,
Don't worry, main thing is that your mate in Southampton gets it 👍
Thanks for considering me though.
Danger is that it might give me ideas, and I've already got way too many😉
All the best, Doug

Hi Peter, have just uploaded a video of the Maiami running with the camera mounted. The video as usual when transferred to You tube has turned out rubbish,- tried all sorts -vid type, size etc, but still the same, (perfect on my computer) one day I'll find the secret. It's strange because some come out perfectly doing the same thing/same camera. It might be something to do with the editing program I'm using. Never mind, you'll get the idea. There's a pic I found of the framing there as well (not a very good one.)
Peter, I never knew you could download to desktop. Fact is, I've never really known how to download anything other than my own photos and when I've tried, I've not been able to get it to appear, so now...I don't bother.

I run a thing called C Clean every week that removes frightening amounts of crap, but there's very little on my desktop as I don't tend to download stuff. I once downloaded Gimp and the computer slowed to a crawl, so I dumped and all was well again. Beyond that I know nothing, as they used to say on Rowan and Martin's Laugh-In!

Peter, there's no way I could download all of the stick. I just don't have the space on my PC as far as I know. I've had to junk flight sims and similar because they slowed it down to a crawl and I'm not a patient man. But I have downloaded some nice plans and will continue looking at it for a few days if I may, then I'll send it on to the next guy.

Hi Red, See last reply, think I'll make a stronger more accurate glassed one sometime, although I may still change this one as well. All the coamings etc come off in 3 pieces so no probs modifying to twin set-up, - rip the single shaft out, couple of holes in the bottom for new shafts plus bracing (I have a spare identical shaft I made 12 years ago)-and another rudder, motor and ESC and she'd be away. I'll chuck you a few pics of it as it is, when I get a minute If you'd like.
