I have a large engine (50 cc gas)with a 20X10 prop. I think that is why it is pulling hard to the left. If any of you have the same problem? What is the best way to fight that problem? It has cooled down and it looks like I will have some time to go flying again. I was thinking about doing a slower roll out and slowly build up my speed. I fly off a blacktop runway. What do you guys think?
