RE: Motor size for GP Extra 300s 40
DGrant,
I expected to have to cut the cowling a bit (for the front, to allow airflow, the side for the cylinder head, and underneath for the exhaust), I was just wanting to see if I would have problems fitting a .61 in otherwise.
Thanks again for all the info. I will check in again when I start the build this fall, and maybe post some pics if anyone is interested.
Cheers!
