a Bipe is not nessaserily hard to fly BUT it definatly flies different, Not all but many also handle very much different taking off, You will need to roll out and keep it on the ground till you get the speed up, With so much lift bipes want to lift fast but if they don't have speed they lift and snap right back down, I would get the Sig SE, that thing can do some crazy stuff and will get your responce time up for sure.

Best of luck
