Well I visited the local hobby shop and made the jump into model aviation. I was sold on the FBC2 due to the ACT mode. After the first flight I almost quit quit smoking. Climbed straight up, Stalled, Dove, Climbed Straight up, Stalled, Dove.... Thank God the wife and kid wasn’t there to here the verbal abuse I was administering to the Gods of Aerodynamics!! All the while at the top of the stall it was breaking hard right. ACT was going nuts and not giving me enough stick to bring the plane back to the left. All configs. were as were straight out of the box. Wing straight, control surfaces faired to stab, gear removed. Finally got it back on the ground, checked the book about trimming pitch with the setscrews. Launched again, rinse and repeat...Finally got to the point that it wouldn’t dolphin when dead stick, but under full power... climb,stall,dive...Turned off ACT and I could actually get control of it. Under low power and dead stick I had the trim setting full left and still had to hold 3/4 left stick to fly straight. Used what knowledge I thought I had to try and trim the yaw axis. Raised the left rudavaitor to keep the plane from flying right. Made it worse. On the second day of flying the plane got away from me and lost it on the other side of a very dense wood line. Had to use gps just to find my way through the woods. Found what was left of the plane in the back yard of someone who was very freaked out to see me pop out of the woods with a Tx and GPS in the hand. Plane was totaled. Did some accident investigation last night. Looks like the aft mount of the PCB broke loose. Could have happened on impact. I would like to believe this happened in flight due to stress of previous impact with tera firma. Everything I have read about this aircraft has been very positive. Just wondering if anybody else has had this problem.

Hi SKYKING,
Let's hold the same post to just one thread please. I am going to drop your other two posts because of redundancy.
Happy flying, Dave

Friend of mine had one - no problem. Sounds like you may have a centre of gravity issue..... Have you checked that against intructions?

I replied to your post under the chalenger does not fly straight thread.
It is to long and to late at night to redo. the problem is fixable and there are mods that can be made to make the planes stronger. I am always tinkering on my sons chalenger and firebird II he is trying to learn how to fly and I am learning how to keep them flying. He is a good kid but like all of us he crashes alot, some are spectacular.
Good luck.

Well, I'm back in bussiness!! Just got home from work and found a package from hobbyzone one on the door step. One new fuse and one very red wing!! I got the tail set up, burned in the motor, re-ran the control lines to the correct side of the tail. Predictions of fog in the morning but if the winds are calm and the skys are clear I will be heading out to my secret flying field. Let yall know how it goes.
