And the answer is....
Fantastic!

At first I ran into an unrelated problem, the plug in the third stopper hole squirted out and I lost tank pressure which resulted in a dead stick landing. No harm done, but that nice glide let me know the CG was dead on and the trim was only a few clicks off perfect. After wringing out the tank's foam rubber wrap and letting the wind dry it out good, I put it back together. I noted from the first short flight that the roll rate was crazy twitchy so I add expo, one hundred percent to be exact and that turned out not to be too much. Elevator was not bad, but I put in 25% to tame it a tad.

The next flight was fun/crazy with blur fast rolls and hit a wall verticals pull ups. The only thing that was a mild distraction was after banking then pulling you needed to hold a tad of opposite aileron to keep it from rolling inverted, like a top heavy boat wanting to capsize. Keep in mind it's really hauling in the turns so it's over in a second. I refrained from putting the stick in the corners because we have a ceiling at that field and I wanted more altitude/time to get out of the flat spin that would most likely result, the CG is further aft than before and may take a bit to pop out of it, so I'll try that elsewhere. Not a hint of flutter!


The third and last flight was a bit shorter when the two screws that held the header on, unscrewed and parted company. There was more vibration on this flight because the engine was turning much higher in flight due to upping the nitro to 30% and a cooler plug for the fuel. It also didn't help that the new Dave brown spinner was well out of balance. I added six 1" strips of masking tape to the inside light side of the spinner to balance, the prop was perfect. I use to think the Dave Brown spinner was as good as a Tru-Turn, looks like I got what I paid for.

It's ready for next weekend.
