To be honest Doug I didn't read down all of the posts, that's why I put the ASR/MCS reference in, just as an aside I was a crew member on four RSLs in UK and abroad and accompanied 1659 to RAF Abingdon for the 50th Anniversary of The RAF Airshow in 1968 which is quite sobering when I realise how long ago that was, the launch was 11 years old then, and it is still working in Holland today.
It might be worth noting that all RAF RSL's were were numbered starting with 16, all the 43ft RSL's were 1640 - 1668, the 41ft 6in RSLs were converted Seaplane Tenders, that were re-designated. they also started with 16 but were lower numbers, with the exception of 1646 and 1647 for some reason. The seaplane tender conversion was actually faster than their successors, 23Kts compared to 20kts (if you were really lucky) but generally about 18Kts. http://www.rafboats.co.uk/rsl43.html this is a a good reference.👍
Upgraded to Brushless 2x1100kva Turnigy motors, Scratch built 1/24 scale. I've included a photo of a real one, just in case somebody else tells me the colour scheme is wrong, East of Gibralta they where white. I'm sitting on the engine hatch nearest the camera, that was 1969
I hope so Dave. I ordered the motors and esc's from Hobbyking Tuesday PM and the arrived this morning 36 hours from order to receipt, very good. Now as this my first dabblings with brushless motors and esc's I have a few problems, which I hope somebody may be able to help me with, I bought a hobbyking esc programming card, there are no instructions with it although it seems a quite straightforward operation to set the required values. Part of this is working out what each item is 1) Running mode. Ok choice of three, forward/brake: forward/ brake/reverse: Forward reverse. (easy enough) 2) Fixed area accelerator: 6%:9%:or 12% (??🤓) 3)Battery Low Voltage Protection. 6 settings from non protection to 3.4v (probably set at no protection as using NiMh) 4)Start Mode (punch): 9 levels, which one? 5)Reverse Force: 4 levels 25-100% (ok self explanatory) 6)Timing Set: 5/10/15/20/25/30/automatic ( which one ) Bearing in mind what the model is (not a competition racer);what I require of it is forward/reverse; port and starboard. I do not require it to take off like a scalded cat with just the props and rudders in the water. Acceleration from stop to max in about 4-5 seconds. I had about a 50 year gap in model boat making until about five years ago the last one i made was when I was 15, although in the years in between I did get to play with the real things when I was in the RAF. So if you do have any advice remember you are telling a person on the wrong side of 69😋, and thanks in advance
Thanks for the info I've gone for 2x30A watercooled esc from hobbyking, the main reason was that they were £13:00 each and seemed less complicated set up than the car ones, I may be wrong, but they will be in a fairly limited space with poor ventilation. If they don't work I'll try the car ones.
I'm looking to upgrade my 34" model of a 68ft Mk2 RTTL from two johnson 555motors (running on 12V nimh) to running brushless. the speed is reasonable at the moment but a bit more would be better. I've been recommended 1000kv turnigy but which one the D3536 series or the D2836 series, anybody got any ideas which would be the better. I'm aiming to run on 9.6v
Stirling was one of the last generation of Rescue & Target Towing Launches built for the RAF and were designated Mk 3 RTTL and were delivered in the mid 1970's. The model is 1/24 scale and is 39inches L.o.a completed November 2015 from donated hull, all else is scratch built. twin 555 motors running at 12v with 2 x 6v 4a sla batteries in parallel, gives a good scale speed, and has about 45min endurance..
I had an issue with Westbourne, ordered props, card was debited, no confirmation email, would not reply to emails, would not answer phone. Dorset Trading Standards are a complete waste of time as they, direct you to Citizens Advice, which is great deal of good as I live in Lincoln. Parts finally arrived after 8 weeks, with a scrawled note on the advice, saying, "sorry, delay caused by supplier". As I understand it, my card should not have been debited until goods were dispatched, leave alone when not in stock. All they had to do was say sorry not in stock or even reply to my email. I will never use this useless company again, and would advise others not to as well. Other members of the club I belong to have said that they have had similar problems.

The 63ft pinnace replaced Its 60ft predecessor, 1955 design 1389 was built In the early 1960's, this type was the workhorse of the RAF Marine Branch, and probably the favourite of the RAF crews. 1389 Is presently at Staines on the Thames undergoing a conversion for her new owners.
