bullyhys thanks for the post.

I'm working on a connection that will allow using the Tamiya TBU (apple) with the system. This way one doesn't need to figure out a way to mount the detectors and hit LED. It will require the purchase of the TBU separately and utilize just the apple portion.

As far as reducing the speed that is a little more complicated as there are several ways to do it and problems with each. Most people using non Tamiya tanks will use the electronics that came with the tank or a separate ESC. They all differ, in addition the motors may be different, whether stock or aftermarket ones are used. So to design something to reduce speed by 25% or 50% becomes complicated. I will need to look and test more.
