I ran the novak in my TA04 whcih went well until the shaft come away from the magnetic rotor....Novak DO not sell spare parts for these motors.
I also use the onboard data logger which recorded various measurements at 1/10 of a second. this is what I got...max AMPS at 75 with max RPM at 37,000 alittle lower than specs state. My TA04 goes far tooooo quick acceleration up to 68 klm/hr is awsome.
where are you going to buy it from ?
