Fantastice boating today. Not only a great morning but boaters Ray Trevor Chris and a.n.other (with an extremely tidy steam river launch, electric,but with a fogger funnel and chuff chuff sounds)<AND rotating fake steam engine> … with several boats apiece. And Mr T.
Admired your flashing Blue light Trevor…a bit bright a day really, but when it gets a bit dim no doubt it will look FANTASTIC.
Had, in order.. Ecranoplan, its usual whizzy self, the TBD, trialling a three blade 35mm prop with a decent amount of pitch on it (I think its a Graupne one) which was going ok. AND the Invincible towing the T22, which I had sailing independently at the end.
Ray had straightened out and tidied up the Belfast which looked the best I have seen it, still a work-in-progress, mind (after 20 years) .
BUT..Mr T`s poor RTTL….which we re-wired last Friday night. This is a bit of a learning curve for Tom, as a complete beginner, trying to get the boat his dad built up and running. I think it is worth recounting the trials and tribulations as it has merit for any new person trying their hand at the boating lark.
SO.. new wiring, speed 600 motors, 50A ESC now. Plopped in the water….lots of zizz, no go.he had forgotten to tighten the couplings up..didnt have the right Allen key at the pondside (we have had a thread about taking tools, and WHAT we take, a while ago)…I popped to the car to get the box of bits. Fixed the coupling. Put it in the water…a few circles, looks promising.Bought it back to the side, held on to the boat and had it running full throttle for 20 sec….all ok. Out to the wide open sea, and very promising indeed! good speed. almost on the plane, sheets of water everywhere. Bring it back..oh dear…dead…fuse gone. Had a look and one propshaft was binding as the nuts were loose, seizing and so stalling one motor. New fuse, re-adjusted the shaft..off he went…..speed NOT quite so good..return to shore…motors hot, ESC hot..not TOO hot but obviously it and the motors would cook if it was run for any length of time, as we suspected might be the case…so…
Have wired up a pair of "standard" 540`s, which Tom can borrow and will be a straight swap into the boat. It will not be as fast, but Tom can then get the hang of controlling the boat, at slower speeds, and the boat will run reliably and for a decent length of time. Didnt ask who sold him the motors, but although they may well be the sort of power he might like, it comes at a price, ie, needing watercooling.
