Your girlfriend bought you a great heli, but a VERY advanced one. I may be the heretic here, but after 14+ yrs in fixed wing R/C and now intro helis, I know how hard it is to go to advanced machines too quickly. Each machine adds another level of complexity. Those levels are good when you have mastered the lesser levels and the machine is the limiting factor. That way you can tell what the difference is with all of the advanced parts, like your symmetrical blades and Bell-Hiller mixing. At the very least as you try to learn in your apartment, go through the Radd's School of Rotary Flight lessons very thoroughly. Send time with each step and get EACH one down completely. BTW, I used the Radd's in my 8'x8' dining area , moving the table out each night! Have fun! Let us all know how you do. Andy
