OK to start engine without wing?
Thanks for the tips guys...
Will gently tape a piece of cloth over the hole / secure the fuselage as suggested
Don't plan to have the engine on for an extended period of time anyway - just to get things started. Was worried about the fuselage jumping off or rotating over due to the effect of decreased weight
BTW the engine is a 4 stroke OS 70 Surpass fitted to a GP Cub 40
in case that makes a difference
This RC forum is great !!! Very helpful bunch of people
