Here is a Tinyhawk 3 inch I built using Quad 66 Skyryder 120 frame that he redesigned for me as a hot swap for the Tinyhawk 2 Race BNF. Its is a complete swap all you need to do is change out the motors from the Emax 3 hole mounted motors to any 4 hole mounted motors. I did add larger M2 jelly between frame and FC. However all that is really needed to make a TH2 Race into a 3 inch ripper is a motor swap the Quad 66 Frame and of course 3 inch props. Everything else below I added were extra upgades that were done after the quad was in the air with suprising performace increase.

I used a tinyled's tinyhawk sled that allowed me to swap out the built in Emax VTX and SPI RX with a TBS Pro32Nano VTX and Crossfire Nano RX with Mini Immortal T antenna giving it much more range and penetration with 500mw output and Crossfire. I also updated the camera to a Runcam Nano 4 and an XT30 power connector.

All in all this is a wonderful 3inch which fits between a Babytooth and a TP3 yet is an easy build as it is almost a complete swap for the Tinyhawk 2 Race and lets pilots upgrade as they go from the 2" Race all the way to 3" Full TBS build while being flyable between the upgrades!

I mainly run this on bi-blades not tri-blades
