Maiden flight was good...Plane flies really well at slow speed no tip stalls at high or low speed..Walls are awesome!! Couldnt get it to harrier or elevator too well but my cg was at 5 so I moved it back a bit to approx 5.5...Flat spins inverted were ok but they should get better after moving the cg back..The Saito 82 ran pretty well inverted and has plenty of power..Landings were trainer-like..just floats right in...Inverted flight needed a bit of down elevator but moving the cg should take care of that..Tumbles were pretty good too..All in all the plane flys very good and doesnt seem to have any bad habits...
