I have a Robbe Futura SE converted to petrol with a Zenoah G23 engine.
I got it second-hand from a guy who is an experienced fixed-wing flyer and modeller but I think had limited heli experience. So I'm sure he set it up as correctly as he could.
As yet I have not flown the heli but have started it and run the engine a bit, setup the swash and general stuff that I know.
My concern is with the drive belt. It seems about the right tension but what concerns me is that when I press in on the belt I can see that the engine can move ever so slightly. This is going to change the angle of the pully on the clutch bell. What I am worried about is the belt chaffing on the frame and self-destructing.
Anyway, as much as I am anxious to fly it I do not want to be hasty and risk any damage so I am inclined to have someone look at it or perhaps there are things I can check myself to be sure the belt will track properly.
