It looks like both s9551 (aileron servos) on my visa have developed some play near the center, after 1 and half seasons. I was not able to find any dedicated replacement gear set for the servo on the market.

Question: is replacement [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXYAF3&P=FR]gear set[/link] for BLS551 compatible with s9551?

Thanks in advance.

I opened up one 9551 servo today and could not find anything wrong with these gears. So I cleaned and re-greased the gears. Seems like the play becomes much smaller after the servo is put back, possibly the original positions of the gears around the center are re-arranged and the mesh improves.

BTW, the 9551 gears are quire similar to those in the BLS551 set and I am waiting a reply from Futaba to confirm.

I put some 9551 (new ones) in my spark this spring and found them to have some play and with the long arms I have to use to get the trow I want for snaps it became some play on the aileron, I have now flown about 200 flights with them and they dont seems to develop any more play (at least not that I have notice) .
But I search for some new ones but have been to lazy to do anything more about it..

The gear set for the BLS551 and 9551 are the same so it will be no issue if you order a set for the 551.

The main gear is not the same in the hole. Waste of time..
