Push pull linkage on the elevator servo solves this problem on the Raptors.

The push pull elevator linkage is cheap. I have a Gohbee 90 and it has push pull on it. It didn't come that way. The Raptor Titans now come with the push pull on elevator and collective. It isn't on there to make it look pretty. I have witnessed this pitching down on 4 Raptors and the push pull fixed all 4.

That is all i have ever flown was raptors and never had the pitchy ness without the push pull on them. I am not saying that push pull might not fix it but if that was the problem i thank gohbee should be the one putting them on the 90`s. I can not be the only one that this has happened to. If any of the rep`s would like to Pm me there phone #`s id love to talk to them and try to get this fixed

What blades are you using? I had MAH 700 on my 90 and was really pitchy in fff. I went to Mav 710 and it went away. I do have a little slop in the links, but not enough to worry about. I was told that the narrow chord tips on the MAH blades make them pitchy. They will 3D like a raped ape, but not good in the fff. The MAV's are a all around good blade, (and cheap).

If you want smooth FFF Dont used Mah trapped blades i have tried two sets and they done the same thing real pitchy .They might be good for all out 3D but for the way i fly i hated them..I think i might have mine all worked out now going to test today had a bad vibe in it and it ended up the nut the holds the pinion on was broke in half. Well it messed the pinion it was real loose..The one way on the clutch went out after about 8 flights. I hope it right now or there will be a Gohbee 90 for sale cheap I like to fly but with this i work on it more than i fly its about 90% working on it And 10% flying..its getting old ..Oh ya i called Dave about the pinion you think he sent one out no i had to pay for it..anyway i hope its all good now im just glad i had alot of parts for a raptor 90 sitting i had to use alot of them..

Oh by the way The Gohbee 50 is a great heli it fly GREAT no trouble out of it at all...

I have been working on this same pitchy fff with my stinger 90. You are right about the MAH tappered blades. The Gohbee 690 blades have been best i've used so far. Dave has been very helpful but being several hours apart its hard to get together to evaluate the problem. For the past couple of days I was able to fly with Wayne Mann so I had him to take a look. He suggested flipping the grips to a leading edge control instead of the trailing edge control. We also put more flybar ratio in it but still less than 1 to 1. This has made a big change for the better. All in all this head is a good design just needed some tweeking. My stinger 30 and 50 both fly great with no issues. This company has the best customer support of any I've delt with and that keeps me as a customer.

I finally found time to fly my gohbee 90 this weekend. What a difference!!!! Flat out passes with her ears laid back are solid with no pitching. It's fun to fly again.
