Your guys "cheap rc's" are a little more than my cheapie! I figured I'd pick up something to play with when my V-Twin Maxx breaks so I picked this old RC10B3 off craigslist for $50. Didn't come with batteries and came with mis-matched Tx/Rx(27mhz Tx and 75mhz Rx) but I threw an old TQ system on it and its great fun. I was suprised to find out the cheap Duratrax Streak ESC(foward only) is 10 cell NiMh capable and has a 12t limit. I threw some 7 cell packs together from a bunch of cells I had laying around and this thing is a blast. The old Epic Green Machine 27t double is great and runs 35mph on 7 cells. I stuck a VXL system on it for about 10 minutes and decided it was just too much on 3s LiPo. Anyway, for $50 I figured it was worth it.
Edit- I took those pics after I bashed it on the backyard dirt track. It jumps suprisingly well and flat tracks corners better than the Maxx.
