Nitro RCX also just started carrying the Leopard brushless systems.For under 60.00 you can go brushless, and from looking at the stats it has just as many adjustments as the dynamite system.Also I have done business with nitro RCX many times and the service is always great.Also if you use the code "RCX10" when ordering you get 10% off your order.I also wanted to point out that Nitro RCX has the best deal on hardcased li-pos in the states..Who can gripe about a 4000 25c lipo for 20.00??By the way, i am not affiliated with them in any way, they are just my favorite for quality electronics gear on the cheap.I love the look on guys faces that race with their wallet when they realize you just kicked their butt with a set-up that costs less than their personal transponder did.LOL!.
