Everyone,

I really need to point out how important it is that a pre/post flight inspection is done each and every time you fly. My experience on sunday can and will happen when you throw your brain in a locker before you go fly.

I had to replace the right frame on my raptor 50 saturday, did everything normally but got distracted by happenings around the house at the very end of the rebuild. I came back and finished it up (or so i thought) and thought that it was good to go. I also set up my new x9303 radio for the raptor on saturday, got everything programmed.

Sunday
I needed to get it trimmed and make sure that everything was working like it was supposed to: Throttle, gyro gains, gov settings etc.

fired up ole reliable (by far the best and most reliable bird in the fleet), set low throttle and had it in the air only a couple of feet to start trimming and all of a sudden, all hell broke loose. The raptor started to flip backwards and i didn't have any control on the elevator and as you all can guess, it flipped backwards about 5 feet away from me right on its top.

turns out, when i got distracted on saturday night, i didn't finish tightening the middle elevator link (the link that is also the pivot for the collective tray) and it backed out causing loss of elevator.

This stupid mistake could have caused someone to get hurt and also cost me $100 to put it back together, you can bet that i'll never not check everything, everytime from now on.

Please use this example to keep yourself in check and don't let the same thing happen to you.

I had that happen to me on an R90 (The orange one in my gallery). At the top of a stall turn it kept doing back flips. Did four flips as it drifted over to the long grass where I finally decided I couldn't do anything about it so I hit hold. I had put Loctite on everything except that one screw on the elevator transfer arm.

Yup, that same bolt got me too. Its one of those items that gets the evil eye before each flight..

BTW, the stock bolt can be replaced with one about 5 - 10mm longer with out ill effect.

OH, and I got my failure on video

it does kinda suck when you have zero control and the only thing thats running through your mind in those 3 seconds are "what the f***". just goes to show you how crazy it is that a $1500 bird was hanging in the balance by a 1/2 cent screw.

YEP! My Rappy 30 has done exactly the same thing. They all seem to enter into a back flip don't they?

I now have a long M3 allen bolt in place of the self tapper - it goes right through the frame half.

Tach.

If i'm gonna do a back flip, i'd like it to be because i wanted to, and not have a holy **** moment, I'm no riva, but you should have seen the flip (half a flip anyway). Looking back on it, it was a great flip right up to the point where it drove the head into terra firma and started spitting blade chunks everywhere (definately did not care to have carbon blade chunks flying by my melon).

If you think a screw may not be done up, check it. I often get up after getting into bed to do a quick check on the helis

I have a preflight routine. It was inspired by my own "overlooked" items and other peoples bad luck, all resulting in needless crashes.

I feel sad because you have to pay 200$ to have the bird in the sky again

I'm just glad that neither my buddy (which was in the direct path while it was flipping backwards) or i was hurt. yeah, the $ to get it back up sucked too. This is the greatest hobby on the planet as far as i'm concerned, but what amazes me is how absolutely fast it can go bad, flying around having a good time and a second later sh*t is flying everywhere.

I'm alot more anal now on my preflights and postflights

some thing similar happened to me but it wasn't the heli.

it was my radio i have a modified dx7 that after doing one of several mods to it fired up my 600N got into a hover and all of a sudden she went strait up a couple of feet first thing i did pull t-hold and nothing happened and then it came back down not to bad on its way back down t-hold activated and not much damage well got out my 450 and it started acting weird like spooling up before i wanted it to so we tried a range check and it did it again 3 times turns out i forgot to hook up the antenna inside the radio moral of this story always do a range check before flying.

Just Flip It
