After my last post here and following the advice i was given i finely got my MDS 40 PRO to throttle up smoothly on the ground but when i lift the plane up and hold it pointing skywards the engine splutters and dies .Can anyone tell me what the problem might be i have checked that the float in the fuel tank is not touching the bottom of the tank when the plane is pointing skywards If i can not get this engine to run reliable i am going to get an OS 40 LA is that a good idea?
Cheers
