I recently adquired a used BVM F-86 60" airframe. It is the older version. I would like to put a Wren Mk IV into it which puts out 14.5 pounds thrust. I have heard of guys flying the same plane on the same engine or similar. Just wondering if it is going to be enough or if I should possibly go P-70 size? I would appreciate any info. I am also looking for a used bypass, fuel cells, exhaust pipe, and some wing tanks for this plane if anybody can help. Thanks Jon
