After my 5th charge my main blades are pretty beat up on my SR but I have 5 sets and 2 more battery packs on the way. I am finally in the SMALL place I am practicing getting where I am getting 1 or 2 minute hovers before I have to set down to keep from hitting something not real sable but still I am not scooting around on the floor. I hope when I get my new blades and battery packs I get a day with out any breeze and I can go where I have a bigger area. I think this well help a lot! Just hope no one notices the blade strikes on the furniture and walls. [X(]
