2.5 inch drone frame

This little drone frame has preformed well for me and is fairly cheap to build. The blot position for the FC and VTX is set up for 25mm mounting. The camera mount is for a 14mm nano camera. The drone can be set up in either a pusher or tractor configuration. I chose the pusher configuration for my drone. The AUW for my build ended up being 110g. 

Parts I used:

• Darwin FPV 15A AIO flight controller

• 1104 4300kv generic brushless motors

• RunCam nano 2

• VTX from a tinyhawk 2 (any VTX with a 25mm hole spacing will work)

• HQProp T2.5X2.5X3

• Radiomaster XR2 Nano 2.4GHz ExpressLRS Receiver

• Gaoneng 2s 450mAh battery

• 4 m3 nuts

• 2 m3 heat set inserts

• 4 16mm m3 bolts

• 2 8mm countersunk m3 bolts

Printing the frame I used 3 walls and 10% cubic infill for the main body. There is a file with modifiers where I made the modifiers 5 walls and 5 bottom layers 

The yellow is the modifiers.

To build the frame you need 4 m3 nuts, and 2 m3 heat set inserts

Heat the nuts into the holes into the frame.

 Then heat the heat set inserts into the frame.

Everything else will install like any other drone.

For the storage box a small length of 1.75mm filament is used for the lock hinge and 2 m3 bolts are used for the lid hinges.
