I have a friend that has tried various mfg. (Radix, Thundertiger, Gohbee, SAB etc. ) blades on his Raptor 50 and all woofing on him. He has rebuilted the head and still have the woofing blade issue. Any suggestions?

Look at the collective servo.
Use a servo that holds position well.
Position the ball inboard as possible on the servo arm
to minimize gear train play effecting pitch changes.
Try to rock collective tray by hand looking for any mounting
problems.

Does it mostly from flip to and from inverted.

Do a search on woof, there's a couple very long threads.

It's something in the collective system

woof

i just got rid of a long nagging problem with woof n poof. i replaced the collective servo, headblock, washout assy, all my linkages and ball links and the last thing that finally got rid of it was i changed out the mixing arms with a full stab control arm set. everything i replaced i replaced with aluminum but the one that i think did the trick was the stab control arm set. the mavrikk part number is mvpv0095/mvpv0443 from heliproz. good luck. lemme know if it works out 4 ya.

I've been having the same problem, switched to a Kasama head and it still does it, could it just be a bad collective servo? It also sounds like I need to check to see if the tray has slop in it.

Have fun...... be safe...... burn fuel....... priceless!

Elevator servo is a more likely suspect in my experience.
But either can cause woof

Redwings, just throw an octopus at it!

What blades are you runing? I've NEVER seen a Kasama head with blade woof.

Woof N Poof

I have a raptor 50 that had the exact same problem and I had the Mavrikk G5's on it. I put on some of the align blades and it seemed to go away. I've gone about five flights without any woof n poof. They only other option is that your servos have to much torque on them so it starts to make the entire head wobble back and fourth.

He got his woofing fixed by flipping the blade grips.

Yes and it only took a few posts to get it sorted out, instead of pages of BS and money

Servo horn was my problem with WOOF N POOF. The servo screw came lose and was stripped. Fixed it and the WOOF N POOF was gone.

+1 on flip the grips! Didnt want to mess with the original design but once i saw the newer raptor 50 had the grips flipped i did my titan and its never woof-poofed again! Feels more solid in the wind too as a side effect. A good pitch servo with a heavy duty arm is also a good improvement-especially if your flying hard.

WOOFING BLADES

I had the same problem when I put Mavrick G5 wide chords on.I could not fix it until I put on some MVPV0339 Metal Grips. It stoped as soon as I put them on.
