Feigao 540 9L and Warrior 9918 Controller

[RC-Monster Mike]

Serum,
Both controllers seem to be having BEC related issues - do you agree? The desription of the problem sounds exactly like low BEC voltage to me. The Cheap tower cells are definately a problem on the first truck, but the melted heatshrink on the second truck is throwing me. These warriors run pretty cool, especially with the 9L (not that hot).
