Traxxas 4-Tec Conversion

Update:

Speed on 2s is pretty poor outside. Maybe 20mph with a tailwind. So, I then tried the XL-5 on 3s lipo. Much better. Seems to handle it ok, but didn't want to take chances, so I put my spare MM/UBEC and configured it to brushed mode. Even with the MM brake force at 100%, it hardly works. Actually, I can hardly see any difference between full brakes and just letting it coast to a stop. Can the Titan motor really be that bad? I disconnected the motor and spun it by hand with the wires touching and then not touching. Almost no brake effect.

Looks like I'm gonna get a motor sooner than I thought! Probably will settle for a Medusa 36-50-3300 or 36-60-3100 on 3s.
