Camera Boat 5 uses another simple "pontoon" design with 90

rotating motor and fan unit with rudder which was added later. Gopro was mounted on rotating servo which gives 360

vision.
Camera operated with phone using Gopro App.
Regarding filming techniques etc. - Still plenty of issues to improve and overcome along the learning curve !.

Mni Tnx Graham for being there with "Bill & Ben" and Jon G7NFK for all your previous help and support since my stroke.

Ok, in the last few seconds you can see the fish strike her. Rudder push rod bent, rudder had no control. Took 15 minutes to retrieve her. Hope I don't have that problem again. 🤔

In the last few seconds of the video you can see her jerk a couple times. Took a big fish strike. Bent the rudder pushrod bad. Lost a crew member figure lol. Not the best maiden voyage.Took about 15 minutes to retrieve her. Now have a fiberglass reinforced pushrod. Just part of the fun in this fantastic hobby!

Just a little more fine tuning before model will be ready for a tiny pond .Its only 16 inch from bow to stern .

This was my very first RC project. In fact, it was only to be a static model, but then things changed.
Currently she's a shelf-queen as the rigging takes a while.
She can be converted to a fishing boat and fitted with a 5 blade 42mm prop and brushed 540 motor.
The sail rudder is larger and requires the prop to be removed.

Found it would fit in the paddling pool, so being a nice sunny day, thought it was about time to wet its' bum. So bright today, smoke and water was hard to see, (I can't win ! - either too bright or too dull😐) Anyhow, everything works well, (just need to adjust the rudders,- bit of right needed), plenty of grunt (only about 1/2 throttle max here,- mostly just 1 motor - don't want to bash the paint off !)- bit hard to control in a small tub !,- needed someone to hold it.

Next stop, the lake !, after I modify the launching trolley and making a stand. Unfortunately can't demo the stereo working due to new YT music censoring rubbish. No different to sitting at the beach with a radio, but YT warns you about copyright which is just moronic.

(dry test)

Still working on a bit more keel weight and trying other rudder profile surface areas to improve turning ! - I think the last two videos may illustrate the need for further improvement in these areas.

A change from Maid Rosalind Thames cruiser blog posts! This winter I added a removable keel and rudder extension to the Bristol Channel Pilot Cutter I built in 2017. I wanted to produce a hull that was truly accurate above and below the waterline, and with the correct lead in the keel and in scale winds she sailed ok, but to get a model to sail realistically, you generally have to add a lot of weight deep down. The last picture shows that for regular display, the ugly keel and rudder extensions come off and the stand's extended legs unscrew. She stands 6' 2" with her new keel, and 4' 6" long. The trials were successful. She sailed beautifully, even tacking those overlapping headsails flawlessly, which is generally quite hard to do with RC! I have up to now only posted blogs as they happen, but I have full documentation of this build and can start a blog for it after Rosalind is finished, if it's OK to publish something from the past. I added a teaser build picture!

Thank you Doug and Stephen for your help in getting the video to work. The stills give little idea of any movement but the video shows she was really trucking! Ed

Part 1. ideal conditions; nearly 30°C, cool Bier at hand😜
Sea Scout built by Dad in the early sixties with a Taycol Target and 6V lead acid wet cells (very wet😡). Renovated and dragged into the 21st century over the last several months 😉
See Build Blog 'Sea Scout 'Jessica'' for details!
Motor: Propdrive 2830, 1000kV, 30mm 3 blade Raboesch prop. Quicrun 16BL30 (30A) ESC with BEC.
Tested with 3 battery types, all started with 99% measured capacity-
1. NiMh 4.2Ah 7.2V, nom. 408gm.
Result: Speed sedate (OK 😉scale river cruising!) No planing.
Max current: 3.6A
End status V / capacity left: At end of short run ca 3 mins. 7.78V 99%.
2. 2S LiPo 4.0Ah 7.4V nom. 257gm.
Result: Speed still sedate but due to lower batt weight at least the forefoot came out of the wet stuff! Max current: 4.1A
End status V / capacity left: At end of short run ca 3 mins. 8.25V 93%.
3. 3S LiPo 4.0Ah 11.1V nom. 315gm.
Result: Now we're getting somewhere!!😁
Good speed, manoeuvrability and planing 😊 Max current: 7.5A
End status: 11.95V 74% after several long runs, ca 20 mins total.
Estimated (extrapolated) endurance on a 4Ah LiPo around one hour - mostly 'full bore' - 'Pedal to the metal man' 😊

The competition!

Final run. (Beer was getting warm😁)

Cap'ns log entry:
Boat dead-weight w/o battery: 1.8kg.
Spray rails to be added!😲
Slight list to port to be trimmed.
Rudder servo to be reversed!!😲
Keel protection to be added: some scratches and flaking from stony sloping shore 🤔
Summary: much as expected👍 Forget anything less than 3S.
Anyone want to buy a batch (4) of new 2S 4Ah 45C Lipos? 'One careful owner'!
Happy boating people, Cheers Doug 😎
PS Many thanks to Camera girl Gisela 👍

I decided to risk a salt water trial, as there is no place I can think of with fresh water and a smooth beach or ramp which doesn't involve a 100 mile round trip (most beaches where I am are ocean beaches and others are soft sand/shell. The only lake I can think of is 112km away and I'm not THAT keen. Launching went ok but retrieval was another matter, not helped by an 8mph side wind (looks calm but is windy) Had a number of goes and discovered a few things which need changing, (extra front guide posts and rollers either end of the pads) The rubber resting pads stick like glue so I'll have to make some pop up rollers at the ends.

The pads hold the boat slightly above the centre rollers to avoid damage and stop it sliding off while shifting it. New front guide posts are needed as the boat only draws about 30mm and goes right over the trailer with it underwater 😮(no prop or rudder sticking out,) so it might help locate it when coming in. Jeep had truckloads of power (just fitted a new even lower geared -geared motor -1000rpm/min @ 12v), but unfortunately being only 2x2 (not 4x4) and being half the weight of the boat/trailer combo it couldn't get a grip in the mud, so needed a bit of assistance, (as did the boat getting onto the trailer). Cut out most of the vid with the boat missing the trailer about 10 times, but scored a direct hit once😊. Heaps of fun trying and heaps of washing and CRC when I got home! Going to need some new bearings at some stage, - the ones in it are rubbish and have only lasted for about a few hours running, noisy as anything now, even with gallons of oil. Stainless NMB ones next if I don't change the jet to something else, (another thought on propulsion happening)💡

Finally got a good day, so raced down to the pond and threw the boat in. 2 problems, 1: battery had run down a bit with all the testing, and the new 18kg digital servo winch needed every bit of 4.8v, so functioned intermittently, meaning not much sail control, 2: jib boom needs a kicking strap to stop it 'skying' and tangling (knew it would happen but wasn't a worry). Apart from that, everything worked perfectly ( cheapo China Futaba knock -off rudder servo still worked fine on the low battery which is a bonus)

Sailed brilliantly like it did over 40 yrs ago, and as it's set will sail hands off on a reach, being nicely balanced, (even with the crappy jib,- which I had to make,- well actually my mother made for me,- back in 1980 after the original was stolen by a kid at the beach, while my back was turned😠) Funnily enough it was made on the same Bernina I used to sew (horrendously) the jib foot after trimming it for the boom a few days ago.

A few more things to improve and add, but pleased to have it back on the water. Another crap video, -seems to get blurry once it's been through the movie editor and You tube ) One day santa might bring me a Gopro, ("yeah right"!)

Haven' seen water in a while so off to the harbor . This was one of the first models I'd ever built in 1974 . I went with my girlfriend to a little creek at Confederation park just in front of the old Hutches fish & chip shack put it in and the rudder jammed full over and it corkscrewed and sank I jumped in without realizing water was only about a foot deep and two feet muck . Moral of the story is she's still my wife .
