I've got some 3010s on the way also.
i thought my Capiche was acting very tail heavy, snapping easily and it didn't want to harrier, moving the ailerons back to center ( just one notch on the flap knob! ) helped loads but harriers weren't nose high flying like on Carters, mine was either trying to climb, or snap out of it.
the really strange thing is that I've now got a servo inside not up the rear.

with the 3010's I've heard Hydrides arn't a good idea, voltage drop on high draw i spose.. so with extra nose weight needed ( maybe i should check where my balance is lol ) should i make up a 6 cell pack, hydride or no, or even a sub-c pack!

can't wait to have proper servos in it and see it respond to what i tell it[8D]
