Cool Paint work.

Sounds like it should work. I would say watch the RPMS on the engines, not sure where the limit would be, but with 4 strokes you can float the valves and this will not be good. I would say 12,000-13,000 rpm should be OK you might be able to go higher but I have no idea how high? Then if the props come out of the water as it could really unload......Just be careful.

The 63S with its pressure regulator away from the case would be better than the 53. Also you could try putting the pressure regulator in a really cool place further away from the engine.

I would suggest the 30% Cool Power Heli fuel so it will cool better. The idea of higher nitro means you will have to open the needles to get mixture correct. this means more fuel, but also more oil flowing through the engine. More fuel means cooler running.

This 30% heli fuel will also help with transition and idle especially when heat is concerned.




Good Luck and keep us posted
