DX-7.... explain this!

[RappyMan]

Here's the vid and pic... This is the first day the Extra 260 has been in the air. We checked the control surfaces & the ailerons were backwards... corrected that & flew the plane. Flew a helicopter and then got the 260 out for a second flight (like 15 minutes later.) On takeoff, the 260 does a roll and goes in. The plane is pretty totalled - all that's holding the nose on is the throttle pushrod. The Moki 180 needs a checkup too... pitts muffler... prop.... spinner....
On the crash site, everything works, but the ailerons are backwards. What the hell? How did that happen? So we change it in the DX-7, turn it off & back on... the DX-7 "forgot" the change to the ailerons! Check the vid - how is this happening?
Horizon is getting a call tomorrow to see what is going on and what they will do. This is not good. The DX-7 has worked fine for over a year now and has 14 aircraft in memory. We have a "Warbird Night" a week from now at our club & this has several of them on it. It needs to work and be working 100% for sure!

(note: the video file will need it's extension changed from ".avi" to ".mpg" for it to play. I had to re-name it to .avi so I could upload the file to FG.

wow...no that is definitely not a good thing. Pretty scary if you ask me. I really hope Horizon takes care of this for their sake and your your warbird's sake.

Pre-flight routine.......before every flight.

Doesn't excuse the problem with the radio, but would have saved your plane

[RappyMan]

I hear you on the pre-flight. It would have saved it. What happened was most un-expected after just flying it 15 minutes ago with everything in the right direction.

RM, I had this happen once. In my case I reset the model and entered all the data again. It fixed the propblem.

After changing anything in your radio on a specific model you should always rebind it. It states this in the manual. If you didnt rebind that could explain it.

Sorry for your loss. I always when taxiing out on to the field I check my surfaces. Cheap insurance.

Ive had the same problem with my DX-7, spend sevral hours figuring it out.

Mine didnt save the changes, when the battery where low, when i rechargede the transmitter, it started saving my data again.

[brandonduley]

did you rebind the rx after you made the changes??

That shouldn't have anything to do with it. The aileron direction isnt saved in the reciever when you bind it, the fail safe positions and the GUID are.

To be honest...the damage doesn't look that bad. The rest of the airframe looks to be in pretty good shape yet. It shouldn't be too much of a problem to patch the nose back on. I've fixed planes that looked much much worse.

But that does suck about the Tx.....hope you get it figured out.

That has nothing to do with it. What seems to have happened was his transmitter lost it's virtual memory. Although the fact that he was able to fly the heli (assuming he used the same tx) has me baffled. Did you fly the heli with the same tx? If so, maybe there is virtual memory for the different aircraft types?
