Has anyone experienced a problem with the alpha 40's engine stalling when going from idel to full thorttle? We have a few new planes at our club with the same problem... The engines start instantly and even after a warmup with the glow batt the engine often stalls during the transition from idel to full. We have tried all the limited needle settings for LS and HS. If it were just 1 plane we would understand but it's at least 3 and 1 is a P51 PTS with the same .46 engine... We can get the planes flying but above half throttle. they sometimes stall on touch and goes... We have gone past the needle limits to get them to fly
Any ideas?
BTW the plane is a great trainer! Flys well. Very simple...

It's not the engine - it's the tuning. Many need to have the limiters removed to be set correctly. Typically this condition is caused by an excessively rich idle mixture.
BTW - they are Evolution engines. Evo is an Italian brand and completely different. Don't slur a brand name just to save typing time.
