IMO The Losi Micro T is a perfect size for indoors. I have a pretty good size house with an open floor plan, but with the micro t you can open it up more because it's so much smaller and it maneuvers around the furniture. I collect antique furniture and the micro t doens't bang it up like a 1/18 would. I'm thinking of selling the micro-t I have. It has the lipo battery, brushless motor, upgraded JR servo, upgraded servo saver, bearing upgrade, stuff like that. The bearings and the LiPo have been installed, everything else is brand new in the box. I will list it in the for sale page eventually but if you're interested let me know. I'm thinning out the herd right now and it's a good time to make offers as I'll take just about anything reasonable.
