Just totaled my T-Rex
Hi guys.

Pretty gutted, just absolutely destroyed my Trex. Don't know where to begin.

So upsetting for so many reasons, firstly, for the first time in my history of flying helis, i felt I had a bird perfectly set up, to the point where I could charge, fly, charge, fly etc.

Just hovering it around, called my dad to come take a look - got a bit cocky, did a pirouette like I used to do with my raptor 30.

Didnt go round as quick as I was used to with the raptor, it started to drift, and I dumbthumbed it, nose first into the grass.

The blades flew off (still intact but broken at the roots) - one hit me in the shoulder - VERY lucky it didnt hit me in the face or neck.

Flybar is mangled, as are blade grips, id therefore guess the feathering spindle and main shaft are gone as well.

Canopy is gone as well.

Electronics seem fine apart from I can't get any life out of the tail servo, I hope its just the servo dead not the gyro!

Taking a moment, it may not be as bad as I think, but it really has gutted me. You know you get that moment where you just want to pack it in!

Its not just the money to fix it, its also the time getting it set-up perfect etc.

I guess ill just leave it for tonight and hopefully the motivation will come back soon.

Seems I may have been a little hasty in my assumptions.

Turns out the blades are fine! It is just the grips that have broken (when the blades flew off I thought they had been busted).

And fortunately I already have a main shaft and flybar spare.

That means technically, I could (hoping the feathering shaft is ok) be just a pair of blade grips and a canopy away from full health!

Anyone else always fear the worst when they crash?

Smackin' your baby into the ground can be an emotional experience. Don't give up, your gonna crash many more times and have to learn to shrug it off and rebuild. Try to look on the bright side, now you have an excuse to upgrade the broken parts with some nice looking bling stuff.Treat me good, I'll treat you better. Treat me bad, I'll treat you worse.

The head is pretty much the SE head (even though its the SA rex), so I can't really see much room for upgrading.

I might get one of those CFK looking Canopies, give my trex a bit more of a mean look!

Well from your latest assessment of the damage it sounds like a minor smack up... No big deal replace the parts set up everything perfect again and get out there and fly... It's all part of the hobby and your going to find it's really easy to rebuild back to perfection... I don't crash like I used to but I got really good at repairing a heli fast....Tom..... No "D" flying....

Yeah it does seem minor now!

didnt seem minor when I had a blade heading for my throat!

How do you tell if a servo is stripped?

Count yourself lucky you or your dad didnt' get hurt by that blade. Your heli can always be replaced but not one's eyesight. Sometimes iv'e thought of quitting this hobby because of the expense and danger but when I lift off its like a high. I guess no pain no gain.I crash therefore I am

You're post says "totaled". It sounds like a fender-bender to me!

Welcome to the club. I've lost count how many crashes I've had. You will to eventually!

Enjoy!

I suggest replacing those blades. At only $13 a pair, it isn't worth risking your life. Normally when blades hit the ground, they will crack, even if you can't see it, and all it takes is one small crack to cause the blade to blow up. And at 2500+rpm, it is not fun, nor safe.

Also, replace all of the shafts. Even a slight 1mm bend will cause vibs, which will destroy a heli very, very fast.
You know you have to many heli's only when your wallet is empty.

I always think the worst of my crashes and this helps me!!!!

Because then I am "pleasantly surprised" when it is only minor or not as bad as I thought. When I first got my rex, I almost wanted to crash it on purpose just to get that first crash out of the way.

If your servo gears are stripped, you may hear the motor with little or no horn movement, and/or you may be able to move the horn by hand with it "breaking free" from the gearing.

I remember being depressed after a crash where the Raptor50 had been flying PERFECT just before.
Got so bad that if I got it flying well, I knew a crash was soon to follow!
However, all those rebuilds must have developed some ability, as she always flys great now, and the crashes are fewer.

What worries me the most is the way the blade grips just snapped. That happened in my one previous crash as well.

Are the plastic blade grips notoriously weak?

I am immensely lucky when I think of it. In all honesty at the time I was more concerned with how the heli was, but as I think about it more, 2 inches to the right and it would have hit my throat. Fortunately I dont think it quite had the pace to cause very serious damage, but still it is an eye opener (excuse the pun).

I had a crash on a TRex 450 SE where it went in full power inverted.

The electronics survived, as did the battery tray. And the blue metal parts in the head and tail (but no head button).

Everything else was totalled. Everything. And then I realized when trying to disassemble it that I had red loctited the frame screws so they just snapped off.

We can rebuild it. We have the technology. We can make it better. Stronger. Faster.

Now it's the most blinged SE on the field with full night gear!

plastic grips
I tend to break one or both every crash, unless I come in flat. I've only had a few so far, but it's definitely a part I keep on hand now. Usually it either breaks one of the grips themselves or the plastic just behind the balljoint, depending on how I hit and luck I guess.
Personally, I think this is a GOOD thing, and it's one of the reasons I've hesitated to install metal grips. That extra force is being soaked up and then released by the grips. When something put enough pressure on the grip to break it, any pressure BEYOND the breakage just went away due to the suddenly free movement of that part. If it didn't break or even bend much what else would have gone?

The head on mine is all metal except for the grips and for now at least it's staying that way. My only complaint is how they hold the pro woods, too snug and it's a hassle sanding the blades there for each set and getting them just right. Not doing it tends to lead to out of track blades for me. I don't crash a lot, and I've decided to lay off the riskier maneuvers for a while, so I'm tempted to just buy another set of carbons. They don't bind. Of course, I have 3 sets of wooden blades in the parts chest from when the hobby shop had a clearance sale, but I'm sure I'll use them eventually.
