RE: Tiger .60 . Building suggestions?
Cure the trike dragging its tail in one EASY step... grab the main LG wire in a vice and a pair of vice grips. Bend (torque) the LG to angle the main struts back appx 7 deg. Put the wheels back on. The thing will no longer drag its tail.
This simply and effectively moves the mains back 1/2 inch. No cutting. No fuss.
The stock nosewheel setup and the prebent main gear leaves the plane sitting just a bit node-high. That leads to "wheelbarrow" takeoffs and landing. There's no realy easy fix... You can partly cure it with a smaller nowsewheel. My plan is to bend new main gear wires to raise the back end. (the supplied wire is softer than I like anyway... not really music wire.)
Ideally the AOA of the wing will be very close to 0 (maybe up to +2 deg... sometimes -1 deg) sitting on the runway. Wth the mains as close to the CG as on the Tiger... you can get away with a negative AOA sitting on the ground. preventing the plane from rotating for lift-off before adequate airspeed is aquired.
+ AOA sitting on the trike gear can have a plane lift early, or ride the nosewheel with the mains off the ground as you gain adequate airspeed (very hard on the rudder servo) If , when sitting still, the plane looks like the nose is up...its wrong.
