HV-Maxx or something else?

Well the wanderer xl motor has a 5 mm shaft. To me they are worth getting new pinions over. You may want to consider a strobe to for new pinions. I have ran the 9xl and 7xl. 12 cells on a 9xl get you about 15 min. I have got 34 min on 20 cells on the same motor. 14 cells on a 8xl should put you about the right run time 10- 15 min depends on driving style. It would be faster than the hv as well. Pick you up some 18 51 gearing 8xl and a 9920 with a strobe slipper system. Your friend will follow you in the choice.
