📝 RAF RTTL Scratch built on GRP hull.

This is my second attempt at scratch building using a a grp hull. My first boat was an MTB/MGB built on a Perkasa hull as a semi-scale model. (see All things Rc - Power setups).
This time I have concentrated on keeping things lighter but it still weighs in at 2.5kg!
I have built without plans, relying on internet photos scaled etc using "Photo deluxe" and "Photo Express".
Virtually everything is built from plasticard apart from a 3mm liteply deck.
The dinghy is epoxy resin and microballoons, ths scramble nets are Lego!
Power is again courtesy of Graupner -2, Speed 600 8.4v using lh. and r.h 35mm props. Esc is one of those 50amp ones from the far east. These are far cheaper than the Viper Marine 40 used in my MGB, but slightly heavier and less sensitive at low speeds. Current drain (in the bath!) is up to 30A but this gives a superb on the water pace of an, estimated,8mph. Battery is a 4,600 mAhr NiMh.
(A true scale speed approaching 150mph plus).
I sail it on Ullswater in the Lake district and the Vosper Perkasa type hull shape is superb in the real waves that we get there, flying over the crests and taking aboard No water!
It really looks the part as my photos would show if I could learn how to load more than one! Can anybody help with this?

Own build in style of late ww2 MGB/MTB using Perkasa type GRP hull, ply deck and platicard superstructure details etc.
Twin Graupner 600 Race motors (-left and right handed rotation), twin rudders.
Bofors and Oerlikons rotate.
First attempt at RC boat build so a bit heavy.
Goes well but short battery life on full throttle. (Motor: 2 x Graupner speed 600) (ESC: Viper Marine 40) (8/10)

📝 reversing switch

Hi. its quite easy. Just buy a pair of lightweight "push and hold, to make switches". Then glue them directly to a minI servo, spaced so that the servo arm is just touching each.
Then, servo operated one way pushes one switch to on and it operates the winch until you release when it automatically switches off. Connect the motor with polarity reversed to the other switch so that operating the servo the other way causes the winch to run in the opposite direction until released when it stops again
Cost of bits - about A£5-A£8 from EBay.
