Here is a review of the Omnibus F4 PDB Flight Controller. Its a cheapie FC with a built in PDB. I flew it with BF 4.05 on it. I used a Foxeer Mix and 2307S 2200kv motors. It is pretty stable and I took it out to a fairly long distance. It seems to do pretty good.
TowerHobbies Millennium Master comes in just over $100 and has a sweet Brushless motor, and all the electronics besides a receiver making this a Rx-R Plane!
