Now I am moving to UHF system (dragon link ) in order to enjoy Fpv with my quad .
Get one of these for your 1.3 vtx and you will get at least a few 100 meters of range.

The harmonics from the 1.3 vtx kill the range of 2.4ghz control if you don't use a filter.

I got my new 3DR radio system installed and I have to say it's great making adjustments live without having to plug the quad into the computer with a usb cable. Makes tuning alot faster and less hassle.

Now if I could only figure out why my quad's yaw drifts...

I am using 1.3mhz low-pass filter :

Without it the range on my bixler decrease to 300 meter. If you want to enjoy Fpv in Israel you must switch into UHF .

That worked, thanks! Just had to set the TX to standard to have the main channels in a correct way for my mode 2 transmitter.

If it drifts slowly over a minute or so there is not a lot you can do other than enabling the onboard compass, gyros always drift a little like that. I term will help for drift that occurs within seconds.

which I term are you refering too? rate, stabilize or stabilize yaw or rate yaw?

My compass is enabled because I have a GPS onboard, but the GPS seems to have stopped working (it worked one time and since I can't get a GPS lock)...

I just put some new motors and gear on my quad last night and reflashed it, so I have to start tuning all over, so I have nothing useful to post atm. But I'll post them when I have something worthwhile.

Thanks! I'm using 980kvs, 8x4.5 on a 4S. Spider frame. should be close.

I spent an hour dialing in the parameters yesterday. No oscillations at this point but i feel that stabilization should be better. The quad isn't unstable by any means but i am constantly correcting to keep it from wandering around. I'm not sure what to play with to keep it more steady. Altitude is constantly changing as well, its either drifting up slowly or down slowly (not using altitude hold).
