More of the Crash boat at our sea water creek and of Peter Dimberline taking a rest after an exhausting day at the radio sticks steering the model. After all, I only did the car loading, driving to the site, carrying fueling and starting, entry to the water and launching and taking the model out of the pond , cleaning and refueling etc to go again. You can see Peter is getting his stamina back. I only ever used 3;1 fuel and in later years 4;1 fuel, just how fast do you want to go? and I have defeated that(annoying) high whine of model engines with my muffler system. Needle valve is left alone and two or three clicks turn out/in in Summer or Winter is of no consequence, maybe too many fiddlers with model engines breaks down reliability? I usually wind the plug out 1 to 2 turns and start her dry and with one or two turns (electric starter belt now) of the flywheel and a fraction choke she STARTS at a bit above idle setting on carby , then throttle to idle disconnect plug lead and then screw in glo plug and lift model casually to pond and slowly place in water at IDLE. Just a bit of a mild throttle check / rudder function check, water outlet check, LOOK AHEAD and if safe clear release and gently open up.
