|  battery life with or without lights on?
i was wondering how much less life you are getting with the lights on all the time. im running my same motor and batterys from my last crawler at about the same weight and only made it about 15 min instead of like 25ish do the lights really drain the battery that bad? im putting them on a switch tonight but was wondering if others have noticed this allso the battery was hotter then normal when i took it out. any ideas

With what gearing tho? The LED lights are not going to rob you of ten minutes run time. Might not even take ten seconds out. Count your spur and pinion teeth between the two, I believe your answer is there....... for both questions |

In a word, YES You went from 55.77 (12/87) to 30-32ish ratio Sorry I cant be more specific, but I am looking up the Wraith stock ratio as I type/edit Maybe YOU could look in your manual and tell me? I think it comes with an 80t spur......... AX30665 so it all comes down to your pinion gear Last edited by cogfounder; 09-03-2011 at 01:13 AM. |

YES, pinion down in tooth count. (motor gear) You will loose some top-end speed, but gain crawling torque, and things will run longer and cooler. But with that chewed up spur comment I wonder if you have your gear-gap set correctly??? Set it too tight, and things bind and heat up, too loose and the gear gets "chewed up" .

Nice looking rig too BTW But not much more than an 87 tooth spur is going to fit in any Axial rig, (SCX or AX type) starts to hit the drive shaft, not to mention it has to still fit inside the new spur gear cover.... to over simplify the issue Last edited by cogfounder; 09-03-2011 at 01:43 AM. |

Might have a bad light board. Hook them up to their own battery I guess. You can get a 4AA battery case at radio shack and a switch to wire in too. Might want to use rechargables in it so your not buying regular ones all the time. Its a bandaid fix but will work and take your main battry out of the picture to get back your run times. Should maybe get in touch with Axial too. They may replace the board for you, but you will probably have to send them your old one first. |

As others have said, no way your lights are going to draw 10 minutes of power from your battery. You're talking a few milli-amps and hour per lamp. Gearing, motor, overall weight will have a far bigger effect on your battery life than a half dozen low draw LED's
