Honestly 1/8 buggy BL I think it is the way to go!!
All U have too do is 5 things for your BL conversion.
1. Find or make a super strong motor mount to fit your ride
2. Find the right spur plastic gear to fit center gear
3. Decide on Pinion gears Mod1
4. Battery mounts
5. Motor and ESC.
and BAMM! A conversion!!!!!!!!
Hope this helps..
