ImpulseRC Micro Apex Arm Key

This is a replacement key for the ImpulseRC Micro Apex frame.

If it is in stock from ImpulseRC, you should buy it from them. But sometimes you lose your key in the field. And often ImpulseRC is out of stock. So this is a stop gap to keep you in the air while you wait to get a genuine one. Seriously, buy the real thing if you can.
