It's improved probably every function of the tank and the communication with the radio is exceptional. In contrast the same radio, receiver and gearbox in my Clark TK22 Tiger is prone to jerkyness and interference. Only solution to that is to get another IBU2.
The only frustration I have is that it's overly fussy about my choice in customised sound samples. The provided SD audio wav files work great. I've noticed that the IBU2 sound files have a sample rate of 176kbp. I'm using Audacity to cut the samples, but it doesnt appear to save the wave file in a format that the board accepts, hmm.
I'll figure it out eventually, now, back to playing
