Thanks for the info. I'm not sure what "ifr's" are; I will do some research, call QF and look into the BLP blocks.

I talked to my friend and its a gas center and he added e85 blocks so the boosters should be gas. It probably didn't run good so that is why he gave it to me :-).

Its this main body (actually a Proform):
