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.
The OMPHobby 49" BIGHORN has been making its rounds and everyone is loving it! We put it through its paces and do our flight review with Donnie, Wes, John, Luke and TJ
