HK90mm viper mw44 conversion she Snaps!
HI guys, took this little viper and put a little 44 in her, IM to the point where Ive had a barely sucessfull maiden flight. SHE SNAPS HARD ON ROTATION !! . Once in the air the rest of the flight was great. tried both flap settings and she had no pitch change what soever the landing was done with full flaps,holding a little power on final and then she just came in for a nice slow uneventful landing. MY question is is the problem possibly a AOA problem? not nose high enough, or possbly its to nose heavy with fuel,fuel is just foward of the cg ,two 16 oz. tanks one in front of the other,with the one in the rear closer to cg draining first. 4oz air trap near the nose balance full. after landing only the rear tank was empty after aprox 4 minutes of flight. I hope you guys can give me some insight on a possible fix. will upload a few pics dont be clowning me on the paint,if I can get it to fly right she will get a new paint job this winter,and a few other upgrade as she will be worth it,also if anybody is thinking mw44, she weight 10lbs full os fuel and the engine is detuned back to 180k.
