I had the U-control version as a boy. The engine scared me, so I just whipped it around on short lines. You are obviously quite comfortable on the sticks since I watched you drive the underpowered version around on the ground with a screaming .049 for a minute or so. Great job and keep 'em coming!
No idea why it came with such heavy landing and such a heavy wing. I sure would like to try it with electric motor and get the battery really far forward.
@@billkuhl442 That would be an experiment which I'd like to see. I'm wondering how you zeroed in on the need for washout. I could see that she was tail heavy, but I don't care to think how long it would have taken me to work that out.
That mushy wobble and nose up indicates stalling wings. Loose motor mount means thrust line is probably down, going to a stall. If the motor mount is loose and prop start is down, the motor is probably pointing down. The motor mount must be firm and secure, and at the correct incidence. That wobble looks like a Dutch roll. It is rolling back and forth, but that can also be caused by too high an attack angle, flow separation and loss of lift. Your rudder was loose in the earlier flights, but presumably that was fixed. All control linkages must be free of slop. Another commenter remarked on the heavy wheels. Presumably the original flew when set up to specification. I searched the Internet, but could not find instructions or manual for this plane.
4 ounces was the weight of the landing gear which I removed. The difference in the flight that did not crash was adding the washout and a little less weight for the RC battery. To me the stab looks rather small compared to the wing. The control system seemed pretty stiff. I wonder about the semi-symmetrical airfoil for so much weight. If I wanted to fly this more the best would be to get strong electric motor and get the battery way up front. Someone was saying more dihedral was added to the wing n later version.
What fuel are you using? I have a couple of Cox .049 Black Widows in the basement that I'd like to revive for my grandson (after decades of sitting), and the old Cox fuel is not available anymore, I assume.

Bill, had one of these when I was a young boy. If you decide you don't want to continue messing with it, I'd be happy to purchase it from you.
I am planning on putting an electric motor in it and lighter wheels.
I have a old teather plane just like this one. Cool to see this fly 👍🏻

4oz landing gear, ouch not a good recipe for 1/2A. Thumbs up on your effort!
I forgot to mention in the video after first hand launch I took off the 4 ounces of landing gear.
Congratulations on achieving your goal.
Having said that, the manufacturer of this model should be thoroughly ashamed. At least it's pretty!

@@Del350K4 Wings that taper at the tips often need washout. If it wasn't so heavy it might not need it.
@@billkuhl442 Ah... because the point of washout is to combat tip-stalling!

I was using Red Max 25% but that is no longer available.
Looks like the rudder is to sensitive.
Once it was flying it seemed fine.
