I have a couple of issues with mine, but I will write back later after everything is fully tested. But right now, my issues are the red servo, the radio seems ok. The receiver is shot. I did change out the BEC to a hextronix 3amp. I havnt tested the fan yet, or charged the battery. I hope all goes well. This is my first purchase from Nitro. Im sortof disappointed. So we will see. after i get it all back together. Ho-Hum
