Hello guys,

Im building a new HC500.

1. Which tail servo are you guys using on the HC500 ? seems like the slot in the frames is made for a 9257 ?

2. my belt seems to want to lie low in the front pulley (see pic) any idea why ??

3. which hole in the main shaft are you using ?

HC 500
You can use either a full sized servo or a 9257...I am using a 9257 and my buddy has a 9254...so it's up to you...

I had the same issue with mine and found the middle hole to work best for me...You also have to pay attention to the way you mount the lower beaing block in place...mount it so that the bearing block is flush with the tail pulley...not so that the recessed side is facing the tail pulley..

i wanted to use a logictech tail servo (6100 regular size) and it wont fit. the hole in the frames seems to be made almost right on the dimensions of the 9257, which is smaller than a regualr sized servo.

How did your friend manage to mount a 9254 ?

tail boom mount
I forgot...he used a trex 500 tail boom mount with a trex 600 tail servo plate to make the full sizer fit...you're right...only the little guy works in the frame..

The full sized servos will help with CG as well...Mine was a bit nose heavy with a 2500mah pack...so I had to add a bit of tail weight
