Oooo, that hurts to look at. But you know what they say - if you ain't crashing, you ain't flying! My flash looked this bad once, and nearly as bad another time. And it looks and flys better than ever as we speak.
Midas, if it doesn't hurt to much to talk about it, could you tell us what happened?

What happened…...
An total basic, done before, to stupid for words F… Up!!
Came in an bit to hot, cause i had to land from the critical site of our field.
The disision was, full in the brakes and yank the nose to the ground or full throttle and an go-around.
Well it was the last but the field was shorter then the throttle response…...
Slamed in to the ridge edge that's on the end of the field and the tarmac edge of the road that lay's on top of that ridge did the rest.
Riped out the gear and destroyed the wing's completely.
The flange's of the maine gears are both broken off coplete….
If i only had that 3 mtrs, extra to gain just that little bit more speed i would have pulled it off...
Getting drunk as we speak

I originally balanced mine at 230mm and found it still to be too heavy on the nose for my taste, I have since balanced mine at 240mm (only a tiny amount of Down Elevator required when Inverted) back from the Wing Joint with around half an inch of Fuel in the Main Tank (as even with an extended flight time, I never really drop below around an Inch in the Main, the plane is very versatile at this CG and Slow Rolls and Knife Edge are effortless with only a tiny amount of down mixed in. I commented to Dave at a meeting last weekend about my UF sinking a little in Knife Edge, but this was later attributed to the fact Ive been flying my Inverza with a immensely powerful Rudder for the last few months, Ive now dropped my Expo to around 15% and find it much better. I wouldn't be worried about balancing it at this measurement, the only thing Id be a little cautious of, is when the plane is completely empty, mine tends to tip up on the Main Wheels, luckily I caught mine on the way down and now have some sponge ready at either end of the day 
Dave......have you every heard of any other UF's running a small amount of 'Up' trim?? Mine even with CG back there, still runs a small amount, the Tail fit is perfect, cant see any big gaps around any of the Wing Seat and have just sort of lived with it thinking it may similar to the Ultra Lightning.

Elevator trim,only when the seams hadn't been flatted down (back area of the tail seat,I permagrit this flat) it only takes a little in the cord of the tailplane.
Ed! Oh, time for No 2!?

Maybe so Dave.......if you could've seen it flying that night though, it literally was a moment of stupidity, most would've been thinking to power up a good 10 seconds before I did, it really was rediculously slow, it maybe is a little too far back, it requires about 4 clicks of Up in fast flight (Futaba), I don't notice it at any point until I fly inverted and it then makes a slight difference to the Nose Drop over a long pass. I'm maybe chasing something that isn't possible with a jet airframe, I normally like them to fly almost straight and level when inverted or the tiniest amount of down Elevator, my thumbs can only manage the Rudder both ways

Nothing wrong with your thumbs! They work just fine :-)
Andreas (CARF designer) likes a neutral aeroplane too, but I think the tailplane area might need to be bigger to achieve what you want.

Thanks Dave, really appreciate that I've been a bit caught up over the last few days with a loss in the family, I was planning to post on the Elvington thread, I'm glad the weather cleared up for us on Sunday, I remember you travelling all the way up here a couple of years ago to be stopped by the weather then, the Vampire flights looked very impressive, especially the whistle......Xcalibur looked like a lot of fun aswell, looking forward to getting to a JMA meets at some point soon, might have to hold off until next year now with the arrival of our little one soon but I'm sure wel all venture down at some point

Thanks for the information Dave and Jame.
I am tempted to take it back to 140 and see how it goes
I fly pretty conservatively so it shouold be ok.
Sorry to hear about your incident Midas. I have some touch up paint at home. Should I get rid of it before the same thing happens to me
Paul.

Sorry about the loss, been balancing some of that myself recently.
Its part of the game travelling, hoping its worth it - years ago I did 600 miles to a German heli event, arrived, unloaded and there was an incident, they cancelled the event and I drove home! Conditioning I think they call it. Best of luck with the new arrival, sure to see you down here sometime.

Good luck. Im fixing my 3m aerobat that was snapped in half...but it was mega expensive to replace so worth the effort... the uf is a great price..might be easier just to buy a new frame....and undercart mount. hope you get back in the air soon no matter which way you go.

Hello Midas feel for the incident, but out of curiosity what size your site ask this because I have a flash ultra in the box but my site is small 120 meters asphalt...hugs

Depends how much time you want to spend repairing , sometimes it is cheaper and easier just to get a new kit ,a fellow at our club never trash an aircraft he always fixes them how is another question., a pity the gears are damaged .
How is the turbine ?and radio gear . Better to check these over before your next flight especially the servo ,servo leads , and the receiver .

Bravo is right in regards to cost. Ive spent 500 AU approx on carbon and glass so far and about a month of my building time to get my plane back to structual sound state. I still have to gel coat paint and thats another month of my available build time...plus hiring a compressor...getting the gel gun....getting gelcoat..etc. Im guessing about 1200 to repair my 5500 plane. All that and it will never be the same...but I loved that model too much... so for me its worth it.
Good luck mate...maybe get a new frame in the same scheme and use the old one for spare parts...pitty about the gear.

KT tail cone is really long, the Flash fuselage was designed around a P-120. You can trim the front former flat with the rail and move the turbine another 3/8" forward. The KT tail pipe is skinny and if you are going without the byepass it will be fine. You need the NACA ducts in the fuselage rear though.
