Hi all,

If I did my math right...the Extra only has 864 sq inches of wing area.

My H9 Edge was a tip stalling beast with 150 more sq inches at 12 lbs....

Check your calculations on wing loading for an aerobatic models....and while these ARFs do build light...
I don't know if you can keep the loading low enough to be happy with it... I think 26 oz sq ft is about the limit...

Nice thing about the Bipe is you can get a LOT of wing area in a smaller package....as nuts as that configuration is....probably gonna be ok with that combo.

Good Luck!
