Hi Guys,
I only just looked into this thread after being caught up in the Heli fourm for a while.
Coshy, that all sounds a bit of a hassle, not to mention the potental for a write off.
The Cap has not flown since the maiden, mostly due to the weather.
I cut up some drink cans and used the thin foil to make the air deflector. Even so I may chicken out and cut another cooling hole in the cowl infront of the engine head. Really don't want to cook my Evolution engine.
I have added some pic's of the Cap, hopefully, never tried an upload here before.

What engine have you in the Ultimate Coshy?
