built sometime in the sixties originally powered by 3.5 cc diesel, then glow motor as in pics OS 20 Max. now converting to Electric. Speed 600BB, Mtroniks Viper 10 ESP, 7.2V 3300ma NIMH. as yet only tank tested seems to have enough power, hope it gets up on the plane.
another photo of my asrl figures are modifyed american 1/32 multI pose airfix a 400 motor a 20amp esc and a 7.2 buggy pack it planes just great took it out today ran for over 3/4 of a hour and the motor never got hot it work a dream now to get my whaleback on the water same scale same firm but with mods on southport model boat lake today sunday
Got this one off ebay, had to use a little artistic licence with the paint scheme as club has several members with same scheme, so didnt want to look the same. The one thing I could not get over was how many parts were left over from the revell kit. Have a 380 motor in it with a msoniks 15 amp esc, could not get over how much ballast was needed to get her to sit in water true, but got there in the end. Now working on making homemade smoke generator to go in funnel, first tests great using nichrome wire and 6v battery, just have to make housing to go in funnel. Have tested parker black ink mixed in smoker fluid and effect looks fantastic.
hI grandadave, if you are talking about the prop going forwards and backwards, then it is the speed controller that handles that. I just put a mtroniks 15amp esc in it and that handles the forwards and backwards no problem. After that it is sorting out the transmitter or just get a cheapy car one off ebay as they have forwards and backwards on them. regards steve
Brian Clewes has now taken his new scratch built boat on its maiden voyage. The day was fine, if cold, but the wind was just right for the event. The auxiliary motor was used to keep the vessel moving when the wind dropped but she did sail with the little wind present and responded well to the helm. This is Brian's third large scratch built yacht, he is really becoming quite an expert. Also makes his own sails and fittings.
I finally got round to trying the Rapier with the lipos I bought recently. My good friend 'Kalamunda' was on hand to drive whilst I took the video. We noticed a marked Improvement in performance- a much greater 'urgency' with the lipos delivering what the motors asked. Short of going up a prop size I think this will be about it with this boat. Thanks to the chaps on here who have encouraged me into Lipos and given help with various matters- not sure what all the worry was now- famous last words!
This will be one of our last days at Crealy in Exeter as the management have decided to terminate our use of the water- so we will be looking for alternatives from January.
I use a little "plug in" voltage alarm on my lipo's. it simply plugs in to the balance charge plug connector. so give you an initial volt test,usually with a few bleeps and a set of green lights, then as the batteries drain, the led's turn red and an alert buzzer goes of as they approach low volt limit, which is set on these alarms at 3.2v, so no damage done to the batteries.
Its a quick search on ebay, loads of sellers, cost around £2.50 each.
very useful bit of kit poolside as you can check all your lipo batteries, even after being used and left to stand, the batteries do recover a bit and possibly ready again for a further shortened run time too.
Those are the alarms I intend to use but they seem to be taking a while to come. They are so cheap I intend to install them in the boat with velcro and extension leads on the balance connectors. The lipos certainly give a weight saving too.
A freind from a photographic club has kindly forwarded these pics to me. Well, you know what its like when you are at the controls, there is never anyone around to take any decent pics, but think these are superb, especially when considering it was going almost flat out at the time, and plenty of "air" under the forward hull, right up the tha last "step" in the hull at the stern.
11.1v lipo, 3000kv motor and standard 3 blade 32mm plastic prop.
I found after some "trial" that the ORIGINAL plastic prop suited the motor better.
I did try a specialist one from prop shop and it actually ran slower, albeit same diameter, but with bigger pitch.
Ok, thanks for that info. I have hot shot tunnel hull and a 47 insane v-hull. I'm big on the fuel driven, nitro or gas. I've been exsperamenting with perpellor size and I've come to the conclusion that I need to get a GPS or other type of tracking device to determine if their is some tpye significant change happening with the performance. I'm just starting this hobby , so is there any recommend reading you would suggest or general knowledge site I could look on for beginners. Thanks in advance for any more help you can provide.
Finally managed to get a fellow club member to take some video for me.
This is a hobby King Tunnel hull boat, running a brushless motor and 11.1v 3 cell.
The weather was a bit windy, hence the rough sound, the water too was slightly choppy, any worse and I would of not run the boat, too risky flipping the hull over !
The boat itself was yet another ebay "rescue" item, sold by "cash converters", all I say it was a great pity the previous owner could not afford to keep it, its a fantastic piece of kit, and so, so much fun to handle. he also did a superb job of applying a different set of decals and repainting it, so thmbs up to this guy, hope that some day he finds this site and the video clip.
Your boat is still being appreciated and being run "as it should be - full throttle"
Its an exciting "ride", full throttle is not for the faint hearted [ha ha]. its a total difference to my normal sailing modes, as Im more used to "scale sailing", so being let loose occaisionally can be fun too. I think everyone should have one, a fast boat that is, purely just for the adrenaline rush you get.
1965 U.S. Lindberg Plastic Special Edition John F Kennedy P T 109 Boat. The P T 109 boat was mainly employed around the islands surrounding the Philippines, hence the reason why the boat was painted to match the background colours of these islands. Bought in a part built state and took me, with help and advice from other model boat guys, about 12 months to get it up and running. Powered by twin motors, shafts & props, with a single 8 cell 9.6 volt battery.
Hello:
I've got a scale model of the pt-109, lindberg and want to build it as soon as possible.
Thank you for these photos... very well achieved the warlike atmosphere of the period.
Soon I'll post pictures of the work.
Built this year 2012 by Colin Burrows as a static model. Bought from him to make RC on 2.4. and currently fitted with a 600 motor that is too powerful, advise that was received from a fellow modeller, I am awaiting for a smaller unit to arrive to make it more authentic as it resembles a power boat rather than a trawler. Am also building a speed boat but have put out a request for wiring information as I have already blown up one speed controller!! lol.
I belong to a recently formed club sailing on the lake a Queens Park, Mablethorpe, Lincolnshire. New members would be most welcomed.
Realistic looking model. Low speed high tork motor would suit this. Model Motors Direct do a 555 which is excellent for most scale boats. What ESC are you using?
You can post details of your club in our Model Boat Clubs section, which should help any prospective members find you. 😀
Hi, I am using a Perkins 5510135 Marine 50amp esc and am awaiting a 25mm diam 300rmp motor from Hongkong to replace the Johnson 600 that is already fitted. it's a suck it and see job as I have no experience in the boating field my previous hobby was flying electric planes with lipo's and brushless motors. Going to fit proportional steam simulator, fog horn and whistle, have already fitted sound generator representing the 3 cylinder steam unit that would have been in the real thing. if you have any experience in the electronics field I would welcome help on esc requirement to power twin graupner 700BB Turbo motors.
Hope this is not considered inappropiate to post this video here as the majority of videos are about baots on the water (hope mine will make it one day) - but would like DaveM (Fleet Admiral) to have a look see.
Just glad it worked out- always a bit worrying recommending possible destruction! I've got another ebay rescue- Maycraft Mercury- which I shall have to tackle this job on.
HI there guys, I am just in process of renewing prop shaft in my 34" fire boat, have for years run it with Ic engine, as not permitted on most sailing areas now Im converting to electric, I have removed the shaft and tube (badly worn from Ic engine use) all I did was firm grip with pliers on the tube twist to dislodge glue and filler then knocked out of the hull from inside.
my intention is to use a speed 600bb for power any comments on power set up would be helpful, my boat weighs in at 2268grams.
