What’s the problem?

I assume this is the one you have?

How about them....? I have the electron on mine this is just me using google LOL ��

Are they from HSD?

If like the above......brakes cable to the pin...may need to reverse the servo control......servo connector to the receiver brake output signal...and the jst red...to a power should work with a 2s Lipo.....

I normally used my #2 receiver battery to power the gear/brake on my jets, unless it’s a large jet which require more juice to function....on these small unit it’s not normally a problem.

Yes it does....but since I don’t own the hsd this is what I found.....they are probably all done by the same factory...so I think..

This look like the unit I posted.....
