So I finally got this baby in the air and it didn't disappoint! Due to a servo problem, I only got two flights on it, but the impressions so far are:
* Flies very light. Floaty, but not to the point where it doesn't want to land.
* Easy to land. Comes in on a perfect slope on high idle and touches down gently pretty much hands off.
* Stable in harriers. There were gusts up to 20 mph which tended to knock it around a bit, but it was easy to correct for.
* Surprisingly locked-in hovers. I had no problem holding steady hovers despite the gusty wind.
* I didn't want to do too many high-energy maneuvers before I know nothing is loose, but I tried a couple of pop-tops and it seemed easy to control.
* Tons of rudder authority! Elevator authority is nice too.
* Tracks straight and clean.
* Once I got it properly tuned, the DA50 hauls this lightweight plane with authority. I wouldn't call it over-powered, but it's just the right amount of power. Good pull-outs and vertical. Thanks for the deal on the engine, [MENTION=712]bbrown2828[/MENTION]! It runs great! (And it was probably perfectly tuned before my fat fingers started messing with it...)
The only small minus I would give the plane is that the wing tube has a slightly loose fit in the receiver tube. There was a small amount of wobble, but it didn't seem to affect anything. I'll probably just wrap the wing tube with a single turn of packing tape.
I'm going to go over all the connections now and make sure I fix my servo problems so I can get it back in the air and get some photos and video.
Special thanks to [MENTION=293]dskuro95[/MENTION] and [MENTION=77]zmonster97[/MENTION] for assistance with the maiden and tuning the engine!
