I built my oldest daughter (She's 2) a Mini summit a few months ago. It started as a VXL but I swapped everything over to a lower powered brushed setup. Its got an Electrifly S-600 motor and I chose an HPI Flux (Castle SV3) ESC because its waterproof AND I can use Castle link to limit forward power. Its set to about %30 right now and its perfect for her in the house. Ive also limited reverse to %25. I got an Exotec Commando body and painted it up in a metal flake Rust red color. She actually knows what the controls on the radio do, her hands just arent big enough to hold it. The final upgrade on this truck was a set of LEDs for the front and rear bumpers.
After I finished her truck I realized, hey, I dont have anything to run with her in the house. So I started building myself another 1/16 Summit. Again, didnt want a brushless setup so I went with another Electrifly S-600 and a waterproof XL5 ESC with LVD. Painted up another Exotec Commando body for mine and I have the LEDs to go into the bumpers but they arent installed yet. I finished it off with a set of Traxxas Canyon tires and Proline 2.2 Desperados. Heres some pics of both.
