this d-box or whatever is lame, hpi retail price is $140. It's just a gyro originially use in heli many years ago, this hpi d-box is the EXACT same unit as the Futaba G190 gyro, about $60 at towerhobbies. look it up and compare them side by side...what a joke. LOL if you want cheap, there is different brand out there going for about $44.00. IMO, you better off spending your money on an extra good battery pack or a couple more sets of drift tires. it's rewarding to be able to drift with SKILL instead of relying on that stuff you know?
