Raptor 90 servo frame

[alicotero]

I have a problem with my raptor 90 servo frame: The pitch servo is attached too deep on the servo frame and his horn touches on the gas servo case.

I've seen another two raptor 90s and their servo frames were different to my servo frame. Their pitch servos were attached more outside and their horns operate over the gas servo without problem.

Are there two different servo frames for raptor 90?



PD: Sorry for my poor english.

There are two servo frames for the Raptor 60/90. The early frame was satisfactory for all 60/90 engines that were available at the time the helicopter was introduced. The servo arm interference you mentioned was a problem with some brands of servos with that servo frame. When the OS 91HS-X C Spec came out the fan casing was redesigned to accommodate that engine and a new servo frame was designed to accommodate the fan housing. I don't think that the problem you mentioned was addressed with the new servo frame. I recently built a R90 SE and it looks like the depth of the pitch servo is the same as the old frame, but it was not a problem using 9252 servos. If your servo arm needs to move that much, an easy solution to your problem is to use shims under the collective pitch servo to allow it to clear the throttle servo. Longer screws should also be used. Be aware that if you get the new servo frame you will also have to get the new fan casing.

Your English is fine. :D

The new Raptor 90 Servo Frame has built in shims as they have addressed that issue. It was a pleasent surprise upon installing the new frame.

I used a extra set of servo mounting plates and put them under the collective servo.It pushed it out to the pefect height.
