Sorry I wasn't clear. The stock tx has what I would call 2 sensitivity modes (marked with an H and L on the tx) as well as two modes for control assignments it(mode 1 and mode 2 on the stock tx). I was referring to the control assignments. I prefer the tx mode 2 which, as I understand, Is actually mode 4 for common tx'es.

Here is the link to the video I have taken of the quad and TX trying 3 binding techniques. All lead to unsuccessful start. The canopy is on but the light is very visible.

If the status LED glows solid, the binding should have worked.

Double check that the throttle trim was not UP. If so, bring it down. Otherwise, the TX would not consider that you have brought Throttle to zero.

Ram, I watched that video several times. I couldn't see the Tx screen too clearly. But what bothered me was that there seemed to always be a bar or two of throttle even when you first turn on the Tx. My theory is that your X1 is still waiting to see the throttle return to zero before it could complete the initialization process. So, you were 99% complete, but missing that last 1%, that's why the bird won't fly.

Leaving the X1 out of the picture for a second. Just turn on the Tx and see if there is a bar of throttle. Could you bring that to zero by playing with the throttle trim? I don't have my X1 in front of me, and I don't remember if the Tx remembers throttle trims or not. If the Tx resets throttle trim at each power cycle, turn it on, then lower it to see if the throttle bar disappear.

If nothing works, remove the top cover of the Tx and try again with the Tx opened. Sometime, a package misalignment causes the throttle stick to be unable to return to zero. I have attached a photo of what I expect to see on the Tx screen when throttle is at zero.

Anyway, concentrate on getting the throttle from 0% to 100%, back to 0%, then slowly throttle up. Good luck.

I think you're right, I'd bet that the throttle trim set too high is the culprit.

^^^ Interesting!
Using the throttle-trim to adjust the throttle down might just work..

Off topic, but, sort of on the same line -

Some quads that use MultiWii boards won't always arm or disarm..
A 'fix' is to adjust the trim in order to get the sticks into the 'right range'..

If it works for those, it might just work for this one too!

Great thinking HP!

This issue is a bit odd, so hopefully that'll do the trick!

Well, I guess I am "all-in" now. I have 2 X-1's due to be delivered the first of the week, an IMAX B6 on order, and a Devo 10 on order. I was able to get the Devo 10 from BG for only $114.46 with the help of a $10 off coupon thanks to HP. Today is my 65th b'day, so the Devo 10 is my present from me to me. lol.

Happy birthday Bill. 65 years old and still acting like a kid good job I'll be 62 in a couple of months.

Aging is not for sissies; nor does one age gracefully or well

I still have not figured out what I want to be when I grow up.

Jay... you are absolutely right... aging is not for sissies. When I grow up I want to be able to fly an R/C model like some of the guys in the videos I watch.

Sam... I really enjoy giving when I can receive at the same time. lol.

Happy B-day old man. I'm RIGHT behind you.
Actually I'm doing great, feeling like I did years ago. Getting away from the job did wonder.

My wife got me an X1 for xmas. It is very stable and binds right up with my 9x. The only thing is its not very responsive. I have my 9x model set to 120% throws on all channels. I saw some mention of setting expo to -50 to make it come alive so I will try that next.

Fair enough I didnt know it went to -80. Heck I'm running er9x so who knows how low it goes. All I know is it dosnt handle the same as my 450 quad so I want to get it as close as I can.
