I have a vtx10r in my desc410r with a vst 550 4.5. Its super fast and smooth but I am having problems with it cutting out when I land jumps. It happens about 2 times a race and steering works never cuts out. I have checked all my plugs I run 4mm soild bullets and I spread them open with a hobby knife and all my solder joints are good. It happens with all my batteries.
