I disagree with the Gas engine on this plane.Wayne is right about weight and wing loading.You both said you read Dick Hansons comments on this combo,I find it funny that neither of you mentioned that Dick said he nor the manfacturer recomends this combo for 3D flying.Dick went to much greater lengths than most of us would or could to make tis plane light,much.We had one with a 2.4 gas and the 3D was non existiant,switched to an OS 1.60 and the plane really shines.The gas engine really ruins this plane as a 3D plane,IMO.You read over and over from the people who really know about 3D,the big boys as I call them,that the key is to keep it light,yet there are still guys insisting on a gas engine in a 25% plane because "they want a Gas plane".I'll stick to my standard statement that is, If you want a gas powered plane,buy one that was designed for a gas engine.It's that simple,the people who design these planes recomend certain engine ranges for a reason,after all we trust them to design the planes,why wouldn't trust their opinion on how to power them.JMO,
