Joe Tosh Posted March 24, 2012 Share Posted March 24, 2012 Not sure, I always believed that It's just logic really: If you put a large pinion on a motor, it will obviously have a much harder time turning it round than it would turning a small pinion round, hence generating more heat cause the load is heavier.

RooBoonix Posted March 24, 2012 Share Posted March 24, 2012 Hence pulling more current from the ESC and making the ESC run hotter, and undergearing the motor makes it spin too fast and generates heat, pulling less current from the ESC as there is less load?

autobutcher Posted March 24, 2012 Share Posted March 24, 2012 So which one is it? Quote Link to comment Share on other sites More sharing options...
RooBoonix Posted March 24, 2012 Share Posted March 24, 2012 Dunno mate! What are the problems? Hot ESC? Hot Motor? Both? Quote Link to comment Share on other sites More sharing options...
Smithy111 Posted March 24, 2012 Share Posted March 24, 2012 Ive just finished bonding my new tyres (dirt paws) for my firestorm and was wondering what people opinons are of running the standard rear ground assults on the front instead of the frontlines?

stretch Posted March 24, 2012 Author Share Posted March 24, 2012 I have just bought a flux vapor speedo and flux vektor 4800 motor to go in my rustler but due to an incident i received two motors from two different stores. What i would like to know would it be worth swapping the flux warp 5700 motor out of my sons firestorm with the spare flux vektor motor? Would the performance increase be worth it or would it be best to sell the spare motor? Neil The 5700 will be faster than the 4600 but have less torque so up to you which one you want the most So which one is it? Hot motor = under geared Hot ESC = over geared Hot everything = Way overgeared Ive just finished bonding my new tyres (dirt paws) for my firestorm and was wondering what people opinons are of running the standard rear ground assults on the front instead of the frontlines? TBH the front stock ones are pretty good at doing the steering duties. Never seen someone run GA'S on the front but give it a go and let us know how you get on.

Smithy111 Posted March 24, 2012 Share Posted March 24, 2012 Ok ill take the spare rears and try em back to back when i next go out with it and report back Quote Link to comment Share on other sites More sharing options...
autobutcher Posted March 24, 2012 Share Posted March 24, 2012 Ok ill take the spare rears and try em back to back when i next go out with it and report back I'm sticking dirt paws on the front as well soon as I can, can never have to much steering(when the fronts are actually touching terra firma) Quote Link to comment Share on other sites More sharing options...
vince1 Posted March 24, 2012 Share Posted March 24, 2012 Just fitted my T-Bone bumpers, the front went on with no trouble but the rear is only being held on by 2 screws. There's 4 holes but i can only get 2 to line up. Is this right or have i done something wrong. Any help gratefully received Quote Link to comment Share on other sites More sharing options...
stretch Posted March 24, 2012 Author Share Posted March 24, 2012 they should all line up ok see here for a fitting guide Quote Link to comment Share on other sites More sharing options...
cat7 Posted March 25, 2012 Share Posted March 25, 2012 My nearly new e-firestorm (with only 2-3 hours running time since I bought it) is making a clicking noise sometimes when its slowing down. It doesnt always do it, sometimes it will do it for a while then it will be quiet for a while, and it seems quiet under hard accelleration. I've been running on a mixture of grass and hard, but sandy, soil with lots of small stones in it. Batteries are 2S and 3S lipos. I checked for stones around the spur gear & cover and driveshafts but theres nothing obvious; in any case if a stone had got stuck I'd expect to hear the sound all the time, which I dont. So, does anyone have any ideas what might be causing this ? Quote Link to comment Share on other sites More sharing options...

notfast Posted March 25, 2012 Share Posted March 25, 2012 Sounds to me like worn driveshafts, where the dogbones meet the cup. I would check there for wear. Quote Link to comment Share on other sites More sharing options...

Thanks, although I've already checked there and its ok - the truck has run for less than 3 hours since new and there are no signs of wear at all. The noise is intermittent , it will do it for a while then it stops again so its a bit puzzling Quote Link to comment Share on other sites More sharing options...

I would be inclined to say yes, but of course I could be mistaking as well. I don't have time right now to surf the web looking for the right answers, but for now: I have always known undergearing to cause hot motors with brushed systems, but generally not with brushless systems where I'd tend to say it's the opposite. Any guru opinions are welcome of course! Quote Link to comment Share on other sites More sharing options...

vince1 Posted March 25, 2012 Share Posted March 25, 2012 I think the bumper maybe faulty as the holes seem to be the wrong way around compared to on the car Quote Link to comment Share on other sites More sharing options...
