Another overheating issue with the CC Sidewinder and 5700

Like the title says... Truck is a 2wd slash and over heats in less than 5min. I am geared down to 15/90 and still its horrible. Why is castle offering this set up for these trucks knowing how bad this problem is?????

Anyone from Castle care to offer any assistance......... I am fed up with set up and run ALL Castle products in my cars. At this point I am starting to doubt the quality. I mean why release a product that has these problems in 1/10th scale vehicles........
