Eco8 - Crash and burn! :-(

Yes... it finally happened (sobbing)

There I was flying my beloved Eco8 at the nearby park. I had just finished "fine tuning" its new 120 deg setup, but it still needed some more work. I had also increased my pitch range from -2 +10 to a more aggressive -6 +10.5/11.

Took off into a hover. Did some forward flight, some loops, but I was mostly trying to get a feel of its new 120 setup. It definitely needed some more adjusting because every time I hit full collective the heli nosed down slightly (the two side linkages were slanted, while the elevator linkage was straight with the servo travel limited) nonetheless I kept on flying .

A family gathered up to watch the "show". They asked me to bring it in closer for them to admire.... I did. I hovered in front of them (at a safe distance) for a little while with the heli's nose facing the wind.

The crash:
I decided to do a tight 180 degree turn, back towards me flying downwind. As I made the turn the helicopter's nose dropped with the wind hitting from the back. I added full collective (with its nose down tendency) and pulled back on the stick.... hmmm.. nothing happened.... CRASH!! Nose-in into the ground . The family went "oooohhhh.." And my mind went "$$$$$$".

The Eco crashed into grass which I think helped absorb part of the impact. Still, it seems to be severely damaged.

Obvious damage:
> Both MS blades cracked at the middle
> Both CF side frames broke!!
> CF flybar snapped both ways
> Lost one of the flybar paddles (couldn't find it)
> Pinion/MainGear/Tail gear are all out of line (something's bent badly)

All Electronic components "appear" to be ok. I'm sure some shafts must be bent!

Total disaster

This is definitely not my week. Last Sunday I smashed my Kyosho glider into a post! Both my digital cameras are not working... and now my Eco 8 went in!

I don't think so... my Logo 10 is not flying this week!

I feel like crap. Fitz, I need some parts!!

Chachin..

P.S: I'll post more information later.. I'm going to go the gym for a little while to unstress myself.

P.P.S: Repairable?? YOU BET!

Hello Carlos

Man I am sorry to hear this. I know how you feel. I remember my first crash with my Eco 8 and I almost got tears in my eye. Dont worry you will have it in the air very soon can back to normal.

Oh, do not throw away any of the carbon things. You can use it to make thing. You blades can be fillet in to thin sheets and you can do what ever with them. I used mine to make CF tail blades for my Pic and House Fly and servo mounts for my Piccolo. Just be creative and you really get all you can get out of them.

Oh, make sure you change the bolt holding on the rotor head and that the metal arms that are screwed to the main grips are both identical.

Last, I see you didnt mention that your boom was harmed Got to love that boom.

Carlo

Carlos,

Sorry to hear about your Eco. I am not looking forward to an experience like that. Why did you go with the 120 setup? Did you think that it would help strengthen the swash setup? Let us know the progress.

man that bites.....gotta hang in there though!!

the fear of driving my eco into the ground is one reason why I sold it and got a raptor. The eco is a great chopper, but its no raptor (at least mine wasnt, carlo's on the other hand.... :-)) b/c that crash wouldve cost you 50 bucks!

Good luck and get that eco back up!

Repairs

Thanks for all the motivation guys, just what I need.

Post-crash inspection:
All right, so I was more relaxed now and took a better look at my smashed-up Eco 8. Yes, many parts were damaged, but I have most of them on hand (lucky me). I still need to order some more.

Other damaged parts:
> Tail belt snapped!
> The canopy looks like crap!

Fixes:
> MS blades: will be replaced by my old stock Wood blades
> CF Frames: are now being replaced by my old stock frames (no more glitches!)
> CF flybar: will be ordered
> Flybar Paddles: will be ordered
> Tail belt: I have another one
> Canopy: whatever.. I'll use the same busted one

It's not that bad after all!! I'm already re-building the helicopter with the old plastic frames. It's coming out pretty nice already. I'm surprised that all my electronics are working (motor, esc, gyro, servos, receiver). What's even more incredible is that my shafts were not bent!! I do have the hardened ones.

I'm also taking the opportunity to install my new Aluminum pulleys from Germany.

And Fitz already re-opened and has the parts I need in stock! My Eco will not be as highly-tuned as before, but will definitely be flying soon!

I'll respond to your comments in a moment. Thanks!

Nice to hear that it isn't as bad as you first thought! Hope you get it back flying soon. You had the aluminum head right? Just out of curiosity, how did it hold up?

Carlo,

This is my first crash! Man it hurts... I'll keep all of my Carbon "stuff" (that's all it is now, stuff) just in case I ever need it for something else. I don't know how to work with CF, but I guess if I really need to.. I'll learn.

Yes, the TU-09B boom survived with NO damage. I think it saved my tail servo together with the linkages and everything. Great purchase!

ebrown, I went with 120 setup just to get performance similar to my Logo 10. You see, before, I was flying my Eco with 90deg servo placement & my Eclipse 7 set to 120 deg mode plus some crappy mixes that compensated for unwanted behavior (it still wasn't good enough).

Now I'm aiming for either a perfect 120 servo placement with straight linkages or 90deg servo placement with a better Tx setup.

Yes rdogg. It held up VERY WELL.. although I just noticed that one of the metallic levers that is connected to a rotor grip is slightly bent! Nothing my pliers won't be able to fix. I still have to check the "feather shaft," is that the name

Another damage:
> Stripped Main gear!

Fix:
> Main gear: I have another one

I really appreciate all the encouragement.. thanks guys!

I know how you feel. I put both my Logo and Voyager in with a week of each other.
Both were repaired with basic parts this time. I'd like to think (HOPE!) it won't happen again.

You know the old saying though, " there are only heli pilots that have, or will crash".

Glad the damage was not that bad.

Foss, not to rub you the wrong way, but what difference does it make it is EP or IC? A crash is a crash. Some just cost more to fix.

I think you just said what the diffrence is...I could care less if my Raptor 50 goes down but the logo...DAMNIT ALL TO HELL!


Weird thing is, the electrics seem to take the dive a lot more often then the gassers.

I wish I really knew. Yes. Yes. Respectively.

Chachin,

There are only two types of models (helis included). Those that have crashed, and those that will. Sorry to hear about your Eco. I've slammed mine into the ground more times than I can remember (I'm not repeating this with the Logo 10). :P It can be surprisingly durable at times, though. I have parts, so you should be able to get in the air soon.

Your comments about the 120deg. setup cought my attention. What servos are you using?

The nose down tendency also may be one or two servos moving more than the others. This can usually fixed by adjusting the ATV of each servo. A swashplate leveler helps setting this up as well.

Yeah helis go down, but you don't hear about EP's doing the funky chicken
