Thanks guys. The TT/DDD engine I am playing with still has its RC carb, so it will be easy to rig a starting and running 2-position linkage. Much safer than sticking your finger near the prop with the engine running.

I suppose it will get more tractable as it runs more. It has less than an hour on it, first as glow, then converted. Also, I have been switching props to get rpm data, and now will settle on what I think will be the best to use ( 8.5 x 6 should do it, I run a Rev-up 7 x 5 on my MP-Jet .061). I want to aim for around 11,500 rpm, flying on 60' lines (.008 solids are legal!).
