very economical new 1/8 buggy roller

not bad, BUT, I had an ultra LX a few years back, and I replaced it with a Hyper 7. The H7 is FAR superior to the ultra car, especially in terms of durability, which is generally much more an issue with these crazy BL setups. I'd spend whatever was needed to get an H7 instead. Part out a nitro RTR if you have to.
