Thoughts on the EVX and Traxxas

Well, it took Traxxas 39 days to get my controller back to me. Traxxas can go to hell as far as I am concerned. They wanted to charge me a $25 "rewire fee" because I cut off the dumb ass Tamiya plugs. I direct soldered the motors and used Deans plugs for the battery packs. You can read all about it HERE, or visit my new website devoted to how much Traxxas sucks: http://www.traxxassucks.com

Anyway, the EVX controller sucks. It has horrible bottom end resolution, extremely restrictive voltage requirements, and it lacks punch in comparison to my old Tekin 411-G2 with only 11 cells! To top it off, it really can't handle much in terms of motors.  The input power must come from exactly two 6-cell packs, primarily due to the BEC regulator being a 7.2 volt unit (see below). So, the input is restricted and the output is restricted.

This simple drawing shows why the EVX is inferior to other high voltage controllers, and why you must use caution when using it.
Basically, all other high voltage controllers (even most of Tekin's "normal" ESCs supported an amazing 4-12 cells, easily making them high voltage controllers) do not have this limitation. Better controllers use a voltage regulator (used for running the logic and control on the ESC itself and for the BEC) that can handle the voltage of ALL the cells in the pack or packs.. What Novak did was use standard regulator circuitry.
Traxxas user's manual is filled with warnings, disclaimers and warranty violation statements. It is simply pathetic!
