Re: Jay's presentation at FOD...your ass.

It always bothers me when "cost/savings" comes up in the subject of a repair.
If your ass is worth anything to anybody, bite the bullet, fix it right, fix it safely and with the
best materials and keep cost and/or cheap out of the equation.
I just thought I'd mention it for others.

I'm also curious about the description of the incident - "lift the tailwheel".  In my opinion, all three gear should leave the ground at the same time.  If the tailwheel comes up, it isn't rigged correctly (adjust the reflexor).  I can see where there could be directional control problems if the tailwheel comes up before you have flying speed.
I know, too late now,  i just thought I would mention it for others.

A main wing repair killed a Q pilot years ago.  Build a new wing,  it's not that bad.

Hi Sam

I have to do a repair on the main wing. . .
Before I bought the project the AC was ready to fly and they were doing taxi tests. long story short... high speed down the run way.., lift the tail wheel,.. lose control...off the runway...nose over...delamination of the bottom skin of main wing.
So the idea is to fist do a repair, and load test the wing. If it holds it's good, if it doesn't then yes... build a new wing. If it wasn't so much work, it would have been easier to scrap the wing, but I did follow your canard replacement project. . . . not a fun job.  
The repair will be about 10% of the cost, and time, so I could save 90%, OR the wing will be 10% more of what it would have been.
I will probably not load test a new wing, but will definitely test the repair.
Getting back to my original question, having flown as many hrs as you have, do you think it is possible to generate a load 2000lb flexing the wing tips 10.5" in flight? I flew with a friend in his Q2, and we tried...pulling the stick back as hard as he could, eye-baling  down the leading edge, we could not observe any flex in the wing.

Looking forward to any advice.

ps. I don't thing the subject of this thread is really appropriate, but I read in q-talk about Jay's presentation, which said " He concentrated his focus on thrust lines, canard and main wing mounting angles and the relationship between them." Which lead me to believe my question had some relevance to the subject. 

Thanks
Bernhardt
