RE: PHOENIX MODELS F-20 TIGERSHARK ?
I missed this coming in to Tower. Interesting. Should be a popular plane.
There are a few guys over in Australia and the eastern rim flying them that I know of.
Four I am aware of have SJ-50 engines, and one other has a 60L. Dub also shipped a 60LX not long ago to NZ destine for a Phx F-20.
From all reports apparently the plane itself flys well, and the kit goes together about like other ARFS. Fixed gear - it is pretty quick, but it is not going to go "really" fast if you have the gear down - the strut/wheel drag is incredible. For most people, this plane is quick enough.
Keep in mind.... it is an ARF - somebody built MOST of it for you - and it is VERY worth while reviewing certain structural elements and carefully considering each control surface, control horn and linkage with respect to the engine you install in it. Take the time to seal all of the control surface gaps too.
Also as HaveBlue noted, the engine mount appears to be somewhat narrow - maybe its set up better for an OS .46 size now.
