Novak XRS CRAP
I just got a replacement xrs back from Novak. The first one ran 6 laps of practice with a P2K2 and an average (1.16) GP 3300 before it started faulting. I only bought it for practice so I could back off a wall if I got hung up. I won't even try the replacement. A Novak tech. called me and told me that the problem with the first controller was that I replaced the stock plugs with Sermos. I replied that I was running a mild stock motor and since the controller was rated for a 15 turn mod, I should be fine. He replied that they rely on the resistance of the bullet connectors and the Tamiya plug to limit the current, and if you replace any connectors, the speed control will not handle even a mold STOCK motor. I talked to a supervisor who also confirmed this. (I didn't even replace the crappy 16 gauge speaker wire they used!)
I've been racing since 1987. I have 15 year old Tekin esc's that still work great. Novak is false advertising their product. They should recall the XRS's.
