Quite like the Elmod boards, it’s the ease of setting up how the tank functions in real time. Some people say it’s expensive with all the extras , no need to buy all of the them . Never had a servo circuit blow or have issues with the LEDs as you don’t need to wire in a resistor. The new Fusion X is nice but do we need a multitude of user sounds, functions and lighting combinations , this new board has much more in the way of extra capability. Suppose if you have recovery, bridge laying or bulldozer functions its good. I am quite happy with customising drive and servos with a few lighting options. Best of all is If you need help it’s always available via email.
