Thanks guys for the input. I have the engine on my 4* 60 and it will pull the pants off it with a 14x6 prop and 15% fuel. I still have the engine rich Still breaking it in.. I have yet to lean it out.. I will try and find a 16x4 and some 30% and get ready for the 540. I hope it will be light enough to play with. I wnat to learn to Torque roll. That is my fav..
