Having been racing R/C for most years than alot of you have been alive. I would like to say the BJ4 and BJ4WE are the highest quality 4wds I have seen. I've raced yokes, schumachers, kyosho, and losi. I'm sure the AE B44 is going to be an ok car, after all it derives alot from the BJ4, but it still ain't no BJ4. By the time you buy the B44 and hopup to race specs, you've bought a BJ4. Will I buy one sure, it ain't a losi.
