Uh Oh.

I've reached a decision point. It's about how to deal with the ailerons.

Should I bevel the edge of 'em then attach as normal or should I try for the Bowman Hinge? If I remember correctly, the Bowman method creates a tape hinge without the need to sand/cut a beveled edge into the ailerons. But does it hold up to the test of time?

I can probably maiden her this weekend, if I can get another hour or two of time in. Remaining to do is:
- Cover / attach the ailerons
- Cover / attach the elevator
- Attach the tailfeathers

So close and now I'm suffering from the Fear of Finishing

She's been flown!!! Unfortunately, there wasn't a camera in sight.

I took her up to Mt. Zion and first flight was off the frontside into some pretty rather sketchy lift. My rates were too high all around so she was quite twitchy, but I did manage to get about 15 minutes of surviving with the occasional passing thermal to play in. I had the entire hill to myself for this flight. I landed in time to avoid the big sink cycle.

Later in the day, the wind switched to the other side of the mountain, and Ian showed up and graciously offered to help sort out the rates and some other fine tuning on my radio. Ian took the sticks and ran her through her paces whilst performing several more adjustments. The end result was much smoother flight and an OhMyGod roll rate. I'll have to learn how to better handle that as every time I hit the OMG mode, I could not keep track of how many rolls, and which end was up.

She does have a nasty tendency to 'flick' at times. Ian believes that I may have a bit of camber introduced by how I set up the aileron neutral position that is contributing to this. I'll readjust that before the next flight.

All-in-all, I believe she'll be a ton of fun despite the extra 'roundness' I've introduced with too many layers of tape on the LE.

Thanks for your help, Ian

In case anyone's wondering what OMG mode is, it's left stick roll.
That's rudder mixed into aileron at 100%. I knocked his normal
right stick rates down to about 35% which is still plenty usable
and keeps it smooth on the high speed passes, but throw left and/or both
sticks over coming out of a dive, and it'll roll 2-3 rolls per second.
I do this on all my planks, wings, other warbirds and the Thorn (basically
anything without a rudder)
