Would like to know what you think of the AXE7245 for powering a 1970 vw bug using a D & D ES_31C motor I am going for a top speed of 40mph and in town driving. I would like to go a 120v but the price is out of my range. The car I am working on is on firstontop com and you can see most of the parts I will use building it. The price of the AXE7245 is $450 is that a good price or should I Keep looking.
It comes as a DIY kit or you can source the components yourself. If you are in a teaching situation it would be an opportunity to teach several skills.

The Alltrax 7245 is a rugged little controller. I used one on my motorbike and I'm planning to use the same controller on my Mini, though just for testing purposes, as I want to go to higher voltage eventually.
The main drawback of the Alltrax for a road vehicle is the way it responds to the throttle. The throttle controls speed rather than torque, so if you apply 25% throttle the controller delivers 25% of maximum voltage (very roughly). On a lightweight motorbike this made slow-speed manouvering quite jerky. I had to be very gentle with the throttle. In a car that weighs around four times as much I don't expect it to be so much of a problem. I'd definitely recommend bolting it to a decent-sized heatsink with plenty of airflow.
