Default Stronger gears for Hitec HS 55?

I am using HS 55's on a foamy parkflyer by insanefoamies.com. They work great except the geartrain is very delicate. A hard landing or even bumping the plane getting it out of the truck often results in a stripped gear tooth. It is always the gear that runs against the main output gear. In the last month it has probably happened 7-8 times. I get 1 free gear strip, because I can rotate the gear 180° for a fresh set of teeth. The next time it happens on that servo I have to use a new gear from the $5 replacement gear set. Does anyone know of an aftermarket HD gear set? Or how about an equivalent servo that is tougher?

You're not using a large enough servo, plane (pun intended) and simple. If the servos strip that easily, one of these days it'll happen in flight. What is this park flyer you speak of?

I would replace the servos with HS81s or equivalent.

They don't make metal gearsets for the HS55 as far as I know.

They now make a HS 56 that has stronger gears.

Thanks guys. Foamaholic, there are no metal 55 gears on servo city. But I did discover the 56 HB, as rcelect said, which looks like the way to go.

Matt, check out www.insanefoamies.com
I have the Edge 540 model. It is similar to other foamies out there, but the kit is very well-equipped and it flies great.

The HS-56 is the way to go for a similar footprint with a stronger torque rating.

Keep in mind that the HS-56 servo arms and base are different sizes from the HS-55 but the case is similar in size.

Good luck!

The OP mentions rotating the main gear 180 degrees and reusing it. How can that be done with the key on the shaft?
