Except maybe a $21 25A EZRun ESC. I have not used a Mamba 25 for years, but I still use Sidewinders and Micro Pros, and I prefer my EZRun any day. For $7-8 extra you can get the programming card and make trackside adjustments in seconds. The "wildest" motor I have used mine on are the CM26-68 and everything runs cool. I dont know what motor you have, but the 25A is usually good up to 26mm motors in the lighter 18th scale cars, but you may want the 35A for heavier vehicles or larger motors. The 35A and 25A both are the same size, but the 35A comes with a fan on top; the fan can be removed for 18th scale use if you don't have enough clearance.


Of course I will always recommend Castle because I think they are reliable and have some of the best customer service. But when it comes to honest to goodness performance for your dollar I believe you will find the EZrun to be on top.
