somebody asked me which engine to run in buggy, the new Team Orion Alpha CRF 3 port, or 7 port. I would say the 3 port hands down. The 7 port is really too much motor for a buggy, but will work better in a truggy. If you are a power junkie, then you can use the 7 port in buggy. Obviously the 3 port will get better mileage...
