Read all the threads in this forum, there are big discusions on the incidents on the stab the firewall and the wing, Mary cross from GP recomended +1,o +1 om stab, wing & engine.-
the word was that all giles needed down trim elevator to fly straid, I did +1,0,+1 and now I use up trim elevator, so is a no win!!
It flys nice, I have a 1.60FX, it land fast and alway kind of tip stalls on you right at touch-down, nevertheless if you loose speed and stall it high, recipe for crash!!
so because of is sweepback wing design alway land it with speed
also put a fiberglass fabric with epoxy at the joint of both half wings.- I t probably will need weight at the tail so try leaving a way to put it in the back, I don not remenber how much mine has, but ALFIRC will tell you since they have 2 in La Paz and he did mine, he put it in before epoxing the tail feathers.
Good luck and enjoy hte flight!°!
