TWE210 Quadcopter Shark Fin and Antenna Mount

I'm sure many of us have built the UAV futures $100 quad. He uses the HSKRC TWE210 frame off of banggood which is a rock solid frame...it's taken many, many hard hits. However, I managed to break off the very back of the tail on the top plate with the antenna mount hole piece on it (you'll want to cut it off and file it down to use this is you haven't broken it yet...but this is so much better). This is a top fin to help with turtle mode, that also has an integrated mount for a stubby antenna. T
