I posted a thread in the nitro engine section but no one replied. I hope someone can help me here. I got a mugen mtx 2 about a month ago and it has a Rossi R12 pixy engine in it. I am curious if anyone can tell me how good of a engine this is. I try to start it with the box I have but I have to take a screw driver to the flywheel to loosen it up to be able to start it. I haad it started once but didnt run it. I was told that it still needs broken in, ran about 4 more times. All I have is the box with no directions. Can someone help me out on this matter if possible. Thanks
