Stripped Servo


During a move from the East Coast home to the West Coast my aileron got knocked into a high position. Like an idiot I tried to adjust it neutral by hand instead of plugging in my transmitted and battery pack, which would have done it without stripping a gear.

I bought a replacement gear set for less than $6 for my Hitec 56HB servo. I only needed to replace one gear. I wanted to replace them all since I had it open, but I could not get the ball bearing off of one of the gears so instead of break that by trying to force it I just reused it since it was NOT damaged. It all works well and dandy now.

The whole process can be done in 20-30 minutes.

Unfortunately, I lost the second half the pictures for this slideshow showing you the reassembly of the servo and the white (bike) grease I used, but all you need to do is follow these two links: The Toys RCForum and RCHelisite.

Please note that if you are making your place sea worthy this would be a great time to use the black non-conductive grease that water proofs your entire servo. I read about that and it sounds neat.

Motor Break-in

I won't recreate the wheel, when you can learn everything you need to know about motor break-ins here on the rcuniverse forum. This is a fantastic write-up.

In this picture I broke-in a brushed motor on the Horizon Hobby Super Cub LP. Note that I used plastic ice packs to cool the motor and two AA batteries, which ran for about 1.5 hours before dying. Usually, I do not break-in with the esc wires still attached, but this time I was lazy and ran the motor with the wires still soldered on. I did remove the gear box and pushed it free so the motor ran under NO load at all. You can't see that in the picture.
