Default SCX10 metal gears

So i got the axial metal gear set today.
got them in and seems like it's really tight. maybe i'm just used to the OEM gears.
Can i use dielectric grease on them or would that not be a good idea?

I used marine greese on my steel trans gears, very smooth.

Yeah i don't have any. i know that it's ok to use dielectric grease when water resisting. that's why i have it but just wanted to know if it would do the job on the metal gears?

Any thick grease works really. Lithium grease I've used. I normally use this nice bearing grease that my neighbor gets for me from his workplace though.

Lithium grease or marine grease is best. They will stick to the gears as it gets hot in the case. Di-electric grease is good for waterproofing on servo's and electrical connections, but not good for high temp applications.

Ok i have ran it a bit since putting in the steel gears and iv'e noticed that the tranny and motor are getting hotter than ever before. would a new spur gear or a new pinion for the motor help?
it seems to have some kind of drag. like something is holding it back not letting it spin freely. i looked on the bag that the steel gears were in and it didn't have a tooth count. so i'm assuming it's the same as stock. they are axial brand so it should be the same.

sounds like there is something wrong if the motor is getting hotter as it shouldn't make any difference

Oh i don't like to hear that. well i guess ill have to pull it apart and look.
i forgot to mention that i also got new tires that are bigger than stock. i think the tire size has something to do with it as well.
it seems to be acting kinda different than before. guess it's time to hit the work bench and take care of it.

Ok i was chatting with someone and they suggested to change the pinion gear. so i'm going to try that to see if it helps with the temps.

One thing to check.... make sure the 3 main screws that hold the metal motor mount to the gearbox are evenly tensioned, if one is to tight it can change the angle of the motor, causing the pinion to not run true with the spur...allso check that the motor is not been forced up by the suspension link nuts.

My wraith has metal gears. Everything is smooth but one day I changed the gearing to 17/87 and I meshed it too tight and it had a drag. Maybe u accidently set it too tight. I know it seems simple but lots of times its simple stuff that does it, when I figured out y my trans was so hard to turn I felt like a dummy especially since I had done it 3 times b4 THAT SAME DAY lol.

Ok i got a new pinion gear 18T. and seems to be helping a lot. got some marine grease finally so all is lubed good. getting a 88T metal spur in a few days.

Has anyone here done the over drive in the front axle? what is the ratio i should get for that?
thanks guys!

I think under driving the rear might be better. It will help with torque twist if you haven't mirror your transmission. Also, the under drive of the rear is slightly more effective than the over driving of the front, ratio wise. Others here may have better info on that.

I'm not sure on what to do know. iv'e read the pros and cons of both. under drive slows it down and over drive chews up tires faster. to much this and that in all iv'e read so i think i'll wait to change the ratio.
I also found out why it seemed to have some drag. the link bolt that is just under the motor was not tight enough and putting pressure upwards on the motor. so i unscrewed the screw until the bolt stopped moving. then i tightened up the screws for the tranny. held the nut in place while tightening the screw for the link/rock slider. fixed the problem. thanks to phmaximus!
ok so iv'e got steel tranny gears, aluminium tranny case in the mail. 18T pinion, 88T spur in the mail.
still got to do something with that wheel slop.

Fun stuff this hobby we have!, just have to experiment to see what works best for you. If you comp, changing your axle ratios may help or hinder you, you have to decide, myself, I run stock. I don't compete. I run with a few guys that do compete and they're always changing stuff, motors, gears, axles, trans, tires, wheels. In my opinion, they dump a bunch of cash and get stressed out over something that's supposed to be fun and relaxing to begin with. Me, I'll take my extra money, get a six pack, and build another truck!

I gonna leave the ratio the same for a bit.i haven't did any comps yet. would like to but i think i'm the only guy in like a 100 miles that is in to the rock crawler part of this hobby.
i love this hobby and love to build, take things apart and fix things. so i can never leave anything stock. even my xbox has windows cut out and lights in it.
after i get this truck and my other rc good and solid ill jump on to my 3rd one.

If ya have the $ to spend then make it as bulletproof as you can get it. Just make sure you're going to use it and not make it a shelf queen. I'm running all stock on my Jeep. 13 lbs, plastic gears, and a brushed motor, no problems.

Hey Rusted, just a bit of info, if you're running a metal spur gear, metal pinion, metal trans gears, something is bound to give somewhere else. I'm not wishing anything bad on your build, but you should have a heads up. Are you running a slipper?, because if not, the next place that stress is going to give is your axles.

Thanks mike for the heads up. yes i have a slipper in there. yep it's all metal and going to get more like some mip drive shafts and some new axle gears. i got a little to much axle slop.
no shelf queen here. snow, rain, mud, water. it's been through it all.
