Flew my Gradian glider in a lot of traffic. Several other planes buzzing my slow moving plane! I am not able to get out of the way! LOL

I built an Ugly Stick clone from DTFB with the paper off. It flew pretty well but the wings looked like they were flexing too much. I tried a roll to see how strong the wings were. They folded up right away.

Apparently if I want to do more aerobatic stuff I'll need to keep the paper on (and the extra weight).

This is Gradian Version 2.0

I dumped the wimpy 300mah 2s Lipo and upgraded to a beefier 500mah 3 cell Lipo.

Also switched the prop to an APC 6x4.

The difference is night and day. Now, it flies much, much better.

The CG is spot on and it glides extremely well. I was able to move around puttering on 30-40% throttle most of the time.

Came down after almost 8 minutes and the battery still had plenty of charge left. I will set the timer for 10 minutes next time.

It also helped that the wind was only 0-5 mph on this day.

Specs: 60 in wingspan. 27 in length, AUW increased from 178g to 205g
Motor: HexTronik 20g Brushless Outrunner 2300kv
Prop: APC 6x4
OrangeRX Receiver
Two 3.7g micro servos
10amp ESC
3s 500mah Lipo
