Since my Sub 250 gram pixracer is complete I thought I would share a parts list and some build pics.
The FC is a small 36x36 Pixhawk based, its capable of full autonomous waypoint flights, ACRO, has 5.8 GHZ Video, I added an inline DVR for doing real time recording. It even has a Wifi module for telemetry over Wifi. All in a small package that does not need registration.
I recently moved all the GPS and Video Tx inside to protect against damage in a crash
Also added aluminum standoffs for strength and moved the battery to the top.

Later upgraded to green aluminum standoffs
NOTE, I was using this with DVR, lag was horrid, so dont use it, its impossible to race with.
