RE: Protech Tojeiro-90 build. The last one?
Well today went flying again with the Tojeiro-90. It flies really well with the 91FX with pipe, swinging an APC 14x10 at 8900 rpm. Today I checked the CG again. Basicly it is balanced perfectly now at app. 16 cms from the leading edge. This is easy to check: without the wings on, I lift the wing tube and the plane stays balanced on the wingtube.
Anyway, today was great flying. The flying of the Tojeiro-90 is much, much better then the Tojeiro-50. Also remarkable is the fact that when you idle the 50, it basicly drops like a brik (let alone if you would have a deadstick). The 90 flies much better when coming in for a landing. This makes you wonder about the discussion earlier on wing load. If this behaviour is decided by wingload, then the 90 must have less wingload then the 50, not more!!
