Nice!!
How did you get the unloaded rpm/v range of the plettenberg if i may ask?
It would be nice to have a convertor, that allows you to type the mass, gearing ratio and the motor information based on your calculator, among with the amount of power available, to see what the load of the controller would be like.
I don't exactly know what you mean, is it the information you need on the lehner motors or is the calculator showing different numbers?
here is the link to the lehner motors but i am sure you allready found it.
Are you willing to share the program with us? Sounds very interesting!
It would be nice for you to have an eagletree car data recorder to compare the practice with the theory..
