OK - hands-up who has had one of their plastic handles fracture and break on their Bitspower valves...

I have used a number of these without issue but today I had one fall apart without much pressure applied to the handle. I suspect the plastic was already compromised and weak as it failed with very little force applied.

I have heard of others experiencing the same issue, so I was not all that surprised when this one let go on me today.

Next question was what to do about it....????

I thought about using some JB weld to try and repair the handle itself but after about an hour of thinking about it I came up with the following repair method...


One of my other serious hobbies is RC heli flying so I have a good deal of RC spares.

I grabbed a servo horn that was a similar diameter to the original handle. These are splined and are designed to be screwed onto an RC servo. As I fly large RC helis, the servos I am accustomed to have very high torque figures and the utilise very strong servo horns.
I thought that these would almost be a drop in replacement for the original Bitspower plastic handle.

The Bitspower valve has an output shaft that is rectangular in shape with rounded ends. I simply notched out a matching rectangular slot in the servo horn's splined center section with a scalpel.

Now the servo horn can be simply placed over the shaft and secured by the original Bitspower screw.

Took about 10 mins all up for the repair....:thup:

These servo horns are way stronger than the original Bitspower handles so they will never break.

You can also buy full aluminium horns in different anodized colours such as silver/black etc They are also available in different shapes such as a two sided arm instead of the four sided one I have used which would match the original handle a lot closer.

You could easily modify these in the same way except that you would need to file a slot rather than cutting it with a scalpel as I have done above.

I'll probably fill in the holes in the arms with some epoxy, sand it back and give it a coat of Matt Black for that professional finish...!

For those that have one of these valves sitting in a draw at home hope you find this thread handy for placing that valve back into service.
