I used to work at HobbyTown, so you'd think I'd have billions of the things... But I've got:
• An original Traxxas Rustler (at this point the only original piece is the chassis)- This had a 5400mAh LiPo, the Traxxas VXL system, and tons of other... personal tweaks.
• An EFlite CX2 (with the red body)
• A HobbyZone (IIRC) Ultra-Micro P51 (the most fun R/C I've ever had)
• An HPI E10 with the R32 body. I painted the calipers red and the discs buffing metallic steel. Tried running it with the VXL system, destroyed every piece of plastic in the drivetrain.
• A Tamiya CC-01 (IIRC) with the Land Cruiser body (painted in the proper Desert Tan that Hammond's Land Cruiser was in the Top Gear Bolivia Special) and lights.
• A Traxxas Blast, heavily modified for running the VXL system that was scavenged from the Rustler after I got tired of stripping gears.
• An HPI Micro-RS4 with the FD RX7 body and lights. It happens to be drift spec, but it's all I could find on eBay. Currently has a bent axle from letting a 13-yo drive it.
• A Losi Micro Rally. Ran it once on the Losi LiPo, and it stripped the pinion gear.
I guess I do have billions of the things. I think only two work ATM, though (just like our real cars!

). I would post pictures, but the family headed to Nassau for Xmas, so I can post pics of palm trees, but not RCs. We also have an HO layout in the basement, but it's not even past the wiring stage.
For my dad's birthday, I made the only model I ever finished:

It's only about 6" tall.
