If you want one just keep an eye on ebay, they go for about 40-60 bucks with light use.
The motor is a hybrid inrunner-outrunner mix. Plenty of torque, more than a feigao. Good motor for 5s to 6s. Spool up is slower than an inrunner, effecientcy is better than most, but not comparable to a neu. Not a bad motor for a buggy, but may be too small for a truggy, the xl version would be better for a heavier vehicle.
