I am also looking for a micro heli for indoor practice only. I was leaning toward the Walkara 4#3 but this Rotofly is interesting. I'm also looking at the Honey Bee King II however it's a little larger than I wanted for indoors.

I was originally looking at the Walkera 4#3 It seems hard to find.

Is there a big difference between the Heli-Max RotoFly EX Mini and the RotoFly Mini EP Helicopter RTF?

Are the parts plentiful?

Which would you recommend for a first time CP pilot for indoors (small space) only?

RotoFly or Honey Bee King II ?

Thanks,

Dave D.
