OK - Well found out tonight that my main frame is not rigid enough!
As soon as I added the extra weight for the video gear, it started to pulse its head off. Take the gear off, and it settled down. So after poking around and looking I noticed that there is quite a bit of "Bounce" in the main frame. GRRR!!!
I used 4mm ply, and I guess I should have thought about that before I went ahead with my build. I am going to try and and glue the 2 ply frames together and hope that stiffens it. I didn't realise I would have this much room, So I really don't need the second platform.
Oh yeah... FPV in this thing is NOT easy - it did not go well.
