Killer,
I have noticed the CF being a little flexible in the tail area. I will be moving up to 2mm CF on our next production run. However it should be OK and I have not noticed many problems with my set-ups. Definately check out the connections on your set-up. Make sure everything is solid, wiggle the wires while under power this will usually show you that there is a loose connection if there is one. Also check the length of the wire coming out of your RX if the black wire is longer than 4 inches before being connected to the deans antennae trim it down to 3.5-4 inches and then connect it to the deans. This usually takes care of the problem. It's an easy step to miss, the Lite manual says 3.5-4inches and the Deans documentation says 6 inches. I have found that 3.5-4 is best and will usually get rid of the glitching. You shouldn't have noise coming from the brushless motor since there is no arcing there. Try these and see if that doesn't help. If not give us a call 310-787-9909 9-5pm.
