Here's a flight vid:

And another, notice it drop out of the sky from LVC at the end (first time that happened to me)

Is that the Syma X5 FPV system you are using? I'm getting crappy reception with mine. Did you modify yours? It works much better than mine.

I'm interested if the Devo 7E will help with the yaw. Hopefully somebody with the yaw issue will be using the Devo 7E and let us know if it helps.

It's the stock Syma fpv kit.

Just found out that instead of unplugging the battery after a tip over or crash you can bring both sticks down and right (calibration) for a few seconds then arm as normal and she flies again

Well great job from HexFet . The deviationTX control is great. It was very easy to capture SPI since all pins on the RX board was indicated. Unfortunatly... the yaw-lag bug is still here ... so fot 100% is not related to protocol ... IMHO more linked with the I-yaw value... and we can't tune these PIDs value in general.

OK. I haven't tried the different channel settings yet. That may do it. Weather has been so crappy here, I haven't had a chance to fly a week so far

Crap! I had my fingers crossed hoping the Devo 7E would have cured the yaw lag.

Thanks for testing this SeBy...always a help. Keep up the good work.

Low Budget night flying with the X1. Got it last night. A bit cold but, ping pong balls and hot glue makes for some fun flying. Sorry for the shakey camera-it was cold!

Shame it won't fix the yaw issue. I would really like to see the H26 control response combined with the brushless power and sleek airframe of the X1. Would be the ultimate RTF quad in that size, I think.

Ok. Mine is here. I'm in the process of evaluating it right now.

Yaw-lag. As you all know, the yaw is proportional. The further you tilt the stick, the faster it gets. Obviously the spin up and down time is the issue, especially in low rate where it takes forever to do both. This can be worked around if you are used to it. Still sucks however. Proportional or not, there should be no reaction delay when you fully tilt/release the stick.

The conundrum I have is the "extended" switch. I only have it taped to the counter right now(windy as heck outside, no way to accurately test anything). I notice that, at a steady throttle, the switch up/down seems to affect the motor speeds to the point of seeing the front or back pull harder.

The yaw issue is definitely in the FC the programing (lol I know, Captain Obvious).

My first flight has me rather impressed, however.

Has ANYONE messed with the "extended" switch and can say what it does or doesn't do?

Conundrum solved.. By Dustin Dunnil

It's headless mode/return to home.

Also, the throttle trim adjusts Idle speeds, and shuts off motors. That I can see on the bench.

The extended button also works to reset the transmitter when you get a no bind condition. Hold it down as you power the TX.

If only the flip button wasn't useless..
