Thanks, @SP0NZ , this is a fun build. If it weren't so windy I'd be out flying it instead of writing this post :ROFLMAO::ROFLMAO:

The weather surprised me this morning with the wind 3mph SE and 32°F. I built it to specs with the new shiny maker board but changed the battery hatch to a latch. With a 2300 3s battery I'm at 637g. It's a very nice predictable flier with no bad habits. I think I might increase the throws a little, maybe one hole on the servo arm. Thanks @SP0NZ !!

The ailerons on this one are a bit smaller due to the rounded wing. I am not surprised that it may need some more throw. Looks like it flies awesome!

Thanks! Took all the servos from the 2nd to the 4th hole on the servo arm. Flies great, very responsive.

Any building suggestions? Built and fly the Ugly Wonder, Bloody
Baron, etc but this has different parts. Want to be sure I build it correctly....
Appreciated!
