Has anyone built the tim farrell mig? I just purchased the plans and wood, planning on using a rossi 61 and turbax fan. the plane calls for the k&B 4.5 but Im at 3700ft MSL. Enough power? Plane is 64"long WS is 42".

Yves at DL models built a prototype a few years ago about that size. You may want to call him for some advice. I saw it fly with a Dynamax and OS-91, it seemed underpowered or the small intake was restricting the air flow. That is a cool jet, wish there was one on the market in glass / foam construction.

I've got a 85" glass fuselage for the MiG-21 with a set of plans to build it. It is a very semi kit the way I sell it, I can sell foam wing cores if you wish or you can cut them your self.
