Raptor Pitching at High Speed

[HeliSmelly]

Just wondering if anyone has experienced a real sensitive pitching tendency of the Raptor 50? At high speed, the nose is either extra sensitive or just plain unstable....pitches up or down very quickly. A way better pilot than me has flown it and he noticed it right away.

I really notice it coming out of a loop. As the speed increases on the back side, the heli pitches up dramatically and squares the loop off at the bottom. My friend can modulate the cyclic to keep it round (I'm not that good yet) but says he doesn't have to do that on other helis. Any ideas?
My setup is:

A Raptor 50 Titan
Metal head and metal blade grips
Mavrik 620 G4 Pro blades
Stock paddles

Thanks,
tim

Is it balanced front to rear? Almost sounds tail heavy.

To check, turn the flybar 90 degrees from the tail boom and pick it up by the flybar(close to the carrier), it should hang level.

I agree with rcspud. I always set mine up slightly nose heavy, but perfect balance is best.

Is your tail plane and vert fin solid or a carbon? if its the white plastic when you drop the nose at speed the tail plane act like a planes and makes the tail go down soon as it is there the angle makes it go up and you get a dolphin thing going on. put a carbon one, the frame only type and that will sort it, it did mine

I have balanced it level. I thought about moving the c.g. forward slightly. I have the stock, solid white tail fin and tail plane. If I change them to carbon, it may move the c.g. forward somewhat as well. I'll check it out.
Thanks

make sure you use the open frame type or it could solve the cg problem but not the dolphin thing that happened with mine

I initially considered leaving the horizontal tail off completely but found that it was required as part of the boom assembly. The Raptor I got came with some upgraded parts two of which were the carbon horizontal and vertical tail fins. Because the boom supports mounted onto the stock white horizontal tail, I couldn't mount the carbon one. How did you mount yours?

mine came with the mount on the boom and the horizontal tail screwed to it. so i could of left it off but as it was i had got the open frame type carbon with the raptor as well so i put it on and it cured the problem
