Has anyone else ran this motor? My other truggy which is a non Tekno I'm running a 1550kv motor on 5s and get 17 1/2 minutes run time. What kind of run time would I be looking at with the 1700kv? Just wondering in case I have to run with the nitros and might need to make a battery swap.
I'm running something similar. 1750L Orion behind a R8S speedo, 5600 mah battery. Geared 20/44. Came off after 11 1/2 minutes @ 165. Adding in the 3 practice laps I had 13 1/2 minutes of track time. Just threw the battery on the charger to store it and it was at 15.6 volts. 15 minutes would definitely be doable as currently configured. Would probably go down a tooth and put in some current limiting beyond that. 20 minutes would be pushing it, but 30 with a pack swap would be no problem. Heat would be the biggest enemy at that point.
