Yesterday my sceadu crashed, i was hovering tail in with ample battery power, no interference and it suddenly flipped in front of me and hit the deck , as if i had just given a full forward cyclic command, pulling back did nothing and it did not rotate or rev up it just flipped and hit the ground the crash damage was, top mixing levers, boom, mast, head, flybar, feathering shaft and blades, has anyone had a similar crash or can anyone explain what happened to me. i am new to heli's and was very down hearted by this crash.

thanks for your time

Sounds like a signal loss or hard glitch. Could have been some one else turning on a TX on the same freq...

Do you fly in a field by your self or are others near?

Dan,

Sorry to hear about your loss (two minute scilence)

I agree with Ken's suggestions, here are a couple more questions.
When you picked up the bits for the post mortem did you check to see if you had lost a ball (if you pardon the expression) on the swashplate, washout, servo arm or mixer arm?
are all your servos still working?

The bad news is .........It could be a case for mulder and scully.
Don't be down hearted, it happens to us all eventually, some sooner than others.
Things usually happen in three's. My suggestion is go to the kitchen and beak two mugs. that should sort out the luck issue.
order the new parts and get flying soon!!

Sorry to hear about that. Did the crystal vibrate out of the socket? Are you using a base loaded antenna? I recently had a heli flip itself while I was spooling it up on the ground. Replaced the reciever, and have not had any problems since... Good luck with it, and hope you get it back up soon.

Thanks, John Cadwell

It's always sad to hear about crashes, especially about the ones that are unexplainable......
Hope you can get it back in the air soon!!!!

JCadwell, I see you mentioned a base-loaded antenna here. Do you think that it may have played a part in the crash or something? I use a base loaded antenna and am just curious as to what you think.

I'm not suggesting it definatley played a part in the crash, but I think in my case it did play a part. Since a base loaded antenna requires cutting the original antenna, and many are crimp on style, I'd suggest that unless it is soldered on, the connection might be suspect. I've had three base loaded antennas, two of which worked fine. I can't pinpoint the third as the crash culprit, but as far as I can tell it was the only compromised sytem component. Perhaps my base loaded antenna had an internal fault (it was soldered to the antenna wire), or maybe I had a massive glitch. Howvever, when I lined up both my helis post crash, and turned them both on, both with base loads, I could get an acceptable range check with one (100+ feet with the TX antenna down), and the other would twitch big time at 15 feet out. When I replaced the antenna with a wire, the glitching stopped, and operation returned to normal.

Thanks, John Cadwell

Base loaded

I have also had problems with base loaded antennas. I was experiencing random glitches until I replace the base loaded with the wire and it stopped. Lots of people run them though and have good luck.....you have to be very careful about how much you cut off of your wire to install and where you install one.

I don't use one anymore.

Scooby,

"Things usually happen in three's. My suggestion is go to the kitchen and beak two mugs. that should sort out the luck issue. "

I LIKE THIS!!!! I think I'll use this advice on some of the newer flyers in our field who feel they are getting jinxed.

As for base loaded antennas. The package fully states that you range test your stock receiver PRIOR to installing them so you have a basis of gauging improved/reduced range.

What I did was to bring a spare receiver/battery/servo combo with the same frequency as the heli with the mini antenna and did a side by side range check to assure me all is ok with my installation.,
