looks great!

that seems like a ton of battery? lots of people are flying the 89 slick on 12s 5000. I would imagine you could push your flight times to ten minutes almost?

Thanks. My friend Rob spoke to Kyle at Aero Model who recommended a 10S setup between 6000 - 10000mAh for the 88" Edge using the Hacker A80-10 motor. Yes, flight times should be around the 8 - 10 min. range.

Balance


Balance required 2 clicks of elevator trim. Notice the (2) 1300 mah Batteries behind the wing tube.

what I was really after was, how does it respond to the 45 inverted upline test? sink, climb, stay the same?

Yes...the balance was neutral on the 45 degree test, as well as just rolling to inverted...no elevator required.
