BEAM E4 self distruction
I'm just going to quote what I posted on crackroll.com, as no one seems to want to respond there.
Hello everyone.
I have a beam E4. So far I like it but have a problem that I can't figure out.
The first 5 - 10 flights on the heli were great. smooth, good power, and all that jazz. Then on one flight that just happened to be over pavement, I had an in flight failure. The heli started to shake violently, I tried to throw into idle one to lose some head speed. It started to calm down, but then I saw parts so I just hit throttle hold and watched it fall 50 some feet.
I didn't think think much of it, I thought it was because the blades were lose in the grips. I was thinking one was leading, and one was lagging, till they piled up on one side.
After repair, I checked everything out, test hover went well and, all seemed normal. I took it out and started to toss it around. Just after exiting a flip to inverted I noticed a vibe. I flipped it back over and it got worse, this time I just went right for throttle hold and, somehow, with a lot of luck I autoed it down for a somewhat good touchdown. there was no tip over or anything. As it was coming down, I saw the 2 tailboom support braces fall off, that was the only damage done.
On my older T-Rex 450's I never glued the tailboom braces into the mounting eyelets, just kinda "stuck" them on for the looks. With the T-rex's it worked fine. Do you all think that was the problem? I'm going to make sure they are glued in well for the next flight. I just want a second opinion on weather that is the issue or not. I'd rather not find out the hard way that wasn't it.
Thanks in advance for any help
Happy flying

RE: BEAM E4 self distruction
The reason for the lack of responses is the general lack of popularity of the helicopter. Which suprises me, it's a really nice model.
Sorry I can't be much help becuase I got rid of mine because it was a nusance supporting too many different kinds of helis.

RE: BEAM E4 self distruction
I figured it was a carbonation of that, and the fact that the Ceackroll site is rather slow.
I figured out some of the problem. Some how the new feathering shaft I put in got bent, I didn't notice it because that helicopter tracks so well it didn't bother it. Also the ESC (CC Phoenix 35) some how is running in governor mode, no matter what setting it's on, and that's messing with the gyro. That in combination with the tail brace rods was most of the problem. I just changed the feathering shaft and will try it out again tomorrow weather permitting.

RE: BEAM E4 self distruction
That's how I found it. The BEAM is such a solid heli the tracking almost never goes out, so even with the severely bent shaft the tracking stayed true.
As of now the heli is flying well. The gov still seems to be on, even though I set it to off and updated the ESCs firmware. Besides the setting on the castle link, is there a good way to tell if the gov is on? The head speed is holding well with a flat, 83% throttle curve, so I'm assuming it's on despite the setting.
If I find anything else out I'll post here to let you know.
Thanks for the reply's!
