Interesting. I thought the tall spacer was required in order to clear the
linkage that extends down below the TB especially while in operation. I know I
read that somewhere. And looking again at my install pics - I would say that it
is indeed a concern. Also - how do they (RC Eng.) accomplish the fuel rail
mounting?
So Bob - how much was the airfoil? How much for the converted M1? Did you have
to send them anything (stock rails, M1 core, etc.)? How about RC Eng. in
general - were they pretty knowledgeable on the subject of late model magnum
performance? Willing to share that knowledge?
Thanks in advance!
