|  Question on Dyno'd motors. Which to use front and rear??
Hey guys, I just bought a pair of Fantom Blitz 35's off a good buddy. He just got the motors back from Fantom and they completely went through them. New brushes, cut the comms, zapped the magnets, new bearings, lubed and cleaned everything. They Dyno'd the motors and I'm just wondering, now that I know the specs of the motors, which one should I run in the front of my berg and which in the rear. Here's the specs. #1: RPM: 11,937 @ 7.0V Power: 46W @ 7.0K Eff: 151.8% @ 10.1k Torque: 82.4 Nmm #2 RPM:12,230 @ 7.0V Power: 48W @ 6.7K Eff: 183.4% @10.3k Torque: 84.3Nmm Also, to those guys who know brushed motors, How do those specs look?? |

I'd probably say put the most powerful motor up front.... The numbers seems weird though, confused how efficiency is over 100%......if they really are, you should sell those to NASA....I am sure they would love a motor that can make more power than it uses... Later EddieO |

Those numbers are really close I'm not sure it makes very much difference but I'd put #2 up front.
