The Hackers are excelent motors IMO. They run every bit as cool and strong as my Lehner and Neu motors. Only downside is the constuction is similar to the feiagos. Pressed end bells so you need to RC-monster heat sink, not to keep it cool, but to keep it from poping an end bell on a big jump.

I put a Hacker B50 10XL in my Xray XB8EC Buggy I just built. It runs stone cold on 5s. I bought mine used as well. I agree with the others, the price for them new is a little out of line. The can on the Lehner and Neu is far superior, but the windings and rotors are top notch. If you run across one for a decent price snag it up.
