Well I to just got a mini rio and it would not get on plane, Stock prop and 2 cell lipo, Prop, shaft and dog fell off @ 2 mineuts in so cant say if it would have ever gotten on plane. New drive stuff and she'll plane if you toss it.
Went to shockwave 26 prop W/2 cell lipo and was quite the as kicker untill motor burned up 5-10 mineuts in?

Now she's got the B2835-2700, 35-40 amp ESC, 2 cell 1050 30C lipos and she screems. With 3 Cell is just about undrivable at WOT!!!

I bought her knowing it was just a platform, so Yeah it may suck out of the box, but now I think I may even give the 27supervee a run for it's money!

The AC wild cat? Not even close I was passing them stock before the shaft fell into the lake, Mini thunder? No sealed cockpit so it sucks.

The mini rio is unbeatable in my opinion.
