Thanks guys, hoping to stretch the flight envelope this weekend and do some formation flying with my buddy's F22.

Ok experienced Freewing Eagle drivers. I cant figure this out. My F15 has flown twice, barely able to get it back on the ground in one piece both times. If I slow it down it starts rolling to the right to the point it is uncontrollable (I had to just roll rt gain speed in the dive to recover it). Even after trimming out it still snaps right. and very unstable.. Right ail input and it snaps over. If the speed is kept high flies ok still crazy roll sensitive, several times I had full left aileron input and until speed increased it was impossible to turn left.. Once I brought the flaps to position 1 it flew OK. With SB deployed and flaps full it stabilizes somewhat (landing was actually not bad). Here is the thing I cant figure out. After the first flight I checked and rechecked the control throws and they are spot on low rates.. Expo is 40% (the correct way). All control surfaces are streamlined with the wing and control throws are perfectly matched, elevators are spot on the required location, flaps are fully retracted. I cannot see any wing or fuselage or tail warp or abnormality. I have checked the cg multiple times both with a Xicoy cg machine as well as a visual check on a cg stand and it checks ever so slightly nose heavy (basically balanced on the forward cg) at the prescribed location ( I believe its 118mm but whatever it says in the manual). I have numerous freewing jets (F22x3, F16X2,Avanti) and have had great success with all of them and am an experienced pilot but for the life of me I cannot figure it out. the only changes I have made is it has electric brakes and a spektrum AS3X receiver ( I have the stabilization turned off). Seems like it flies much better with the flaps down but I should not have to maintain that sort of speed to keep it upright (too Heavy?). Any thoughts?

I assumed it was something I screwed up (cg,control throws, sub trim etc) however this one has me stumped. I know it is a good flying aircraft but I have checked and rechecked everything. The only thing I can think of is put it on a diet, take the heavier wheels with brakes off, change out the receiver for something else recheck everything again, weigh it and see where we are at. Maybe I will check the wing incidence. Is it possible one of the gear doors is causing drag? The odd thing was when I was full flaps, gear and SB it seemed fairly stable in the landing configuration. Now its a challenge to figure out the reason.
