Remember this one?

Well, it dont look like that anymore....

I pulled a great Bunny-Hoppin-Nube of mistake while FPV-ing yesterday. In the middle of a highbank turn, about 250 yards downrange, I looked up from the goggles to get some situational awareness of the heli (there are some trees nearby). It took a fraction of a second too long to acquire it, and by the time I did it was about 40' AGL, inverted, and falling (climbing?) fast. If it were set up for 3D I might have been able to drive out of it. but it was more tuned for scale...and...well...

As it turns out, you can cut some pretty big tree branches with a TRex600 and glass fiber blades going about 1800 rpm...

Amazingly enough, there was no damage to the video gear and only minor damage to the mechanics. The fuse is a total loss of course but aside from that, repairs arent too expensive....

Boy, that sucked tho...there's nothing quite like that sickening feeling of knowing its going down, that there's nothing you can do but hit throttle hold and watch the fireworks. And that sound...that bone-breaking crunch of fiberglass and carbon fiber meeting wood and stone...

*Sigh* back to the workshop...I had used TT's military MD530 but now they have that civilian variant...think I'll try that one this time. It'll save me the work of painting.

Just submitted the order for repair parts and the new fuse

Best way to recover from this kind of thing is to get right back in the saddle again!

The fuse looks repairable. It may be alot of work but I think it can be done.

Always a shame to see something like this. Glad all the innards were okay- you'll have that new bird up in no time.

Very nasty but the up side is you get to build another one

About the fuse being repairable...na, not really. Its split from the small end of the boom all the way up the spine to the opening in the doghouse. The holes where the legs come out on the right side are crumpled pretty bad, the fuse is cracked from the front door opening down to the front skid hole and there's a deep crack running from just under the right side front door opening to the rear "exhaust".

In theory, the fiberglass can be patched and filled but realistically, this thing was so heavy to begin with and the paint was so crappy to begin with that repairs, besides being excruciatingly tedious, would be prohibitavely expensive and involve the complete stipping of all paint inside and out (yeah, i painted the inside too). Its worth the cost to just buy a new skin.

About feeling nervous- let me tell you the back story to this old bird. Its first test flight was 6 June 07. First shake-down flight was 8 June 07 and it has flown for about 8 hours a week ever since. THere are well over 250 hours on this thing and there has NEVER been a menchanical problem. It has never crashed or even come close to crashing...except for the times I was trying to make the earth flinch by flying directy at the ground at about 50mph...those were some close calls but mechanically this has been a totally sound build and Im thoroughly satisfied with Thunder Tiger and Align.

Take your time building it, make things solid. Ensure that the mechanics are flyable long before you mess with a fuse and you wont have any problems.

Just go fly! As pointed out before- the fuse protected the mechanics VERY well. A friend of mine did a much softer crash and had HUGE damage to the mechanics. This was a HUGE, highspeed inverted crash through trees and there was suprisingly little damage.

Dont be afraid, just be careful.

A very sincere "sorry for your loss". We have seen your photos many times and it is such a beautiful bird. Don't give up,, do another and post the pics so we can see. I have a heli project going on now and shudder at the thought of burying the blades. Heads up my friend!
