Negative Dihedral

Picked up my Beast last Friday. Flew a half flight while trimming until it met with one of the bushes in the yard. Damaged the I-strut and pulled some flying wires loose.

Dave,
You could use a hard hat. That would be a stable platform for the camera. You could also rig up some sort of "gunsite" to keep the aircraft in frame.

Great Video Dave. Multiple take offs and landings, that's what I like to see. The aircraft and you handled the wind just fine. I noticed the Flags ah-flappin'.

Steve,
I understood the strips under the spar caps, but not the aileron ones. The aileron trailing edge is quite hefty and I'm not seeing what the carbon strip does. I don't think it is there just...

Aileron Question

Can anyone tell me the purpose of the carbon fiber strip that is glued onto the trailing edge of the aileron. You can't sand the trailing edge round with it there.

Dave,
Here is another fix. Loctite 680 on the mating surfaces. Clean with Alc first. Not sure if reg LT will work as good. I used 680 to "glue" some 8" steam loco drivers onto 1" axles. Haven't come...

What does it take to balance ? Can you move battery forward any ?
That is a big wing and to add an ounce or two up front should not hurt.
