Flew the 4* today and after putting the washers behind the left side of the engine mount and moving the clevis to the outer servo arm hole she rolls just fine [8D] . I can roll her now with no effort just right or left aileron no rudder no down elevator needed . I can even do a roll like I like to coming in slow over the middle of the field throttle up quickly with up elevator then right or left aileron rolling while going up . I am now very pleased with the 4* I didn't think it was me since I could do this with much less aerobatic planes . I know I am changing subjects but my OS .46 AX on the 4* was starting with 1 flip or 2 and I now have to use the electric starter . It don't seem to stay primed I prime it then you can see the fuel go to the carb but by the time I put the glow starter on it you can see the fuel in the line go back toward the fuel tank [:@] . It never use to do that and the .46 AX on my Twist is starting with just a flip and stays primed . Once the engine starts it runs great like the other one . What could cause it not to stay primed but it runs fine once started ?
