I picked up a cheap RR Lightning and I have a few questions?????
I tried to put my Ofna JP1 pipe on it and the header is to big. I think the engine is a .21?
Any idea why the header is too big to fit on the engine. is this common
also, Are there any bodies available to fit the Lightning 1? is it the same as the 2?

Any other info will be helpful also...
Like the difference between the 1 and 2...stuff like that

thanks
