transmission gears

[ax10newguy]

does anyone know of aftermarket gears for the axial trans? more specific, do they make a set of Higher gears so i can get more top end?? asked at the lhs, but no dice. was wondering if there is some small vendor making them.
probelem is that on 3s after a while the motor gets hot and shuts down ( thermal mode) ppl tell me to gear down, but i say no!! i want to go faster. plus i think that higher gears in the trans will make it run cooler. my esc dosent get hot at all.

my pinion spur is 54/18
vxl
3s

i can run this thing all day on 2s with no heat issues. but 3s is fantastic.

can anyone point me in the right direction?

I dont know of any gear swaps for the trans but you can gear down and motor up.
Try a 4500-5600kv motor and gear down.

If you want to go faster, ditch the vxl system and run a mmp 2400kv. 4s and your ready to fly!

Idk how your not satisfying your need for speed with a vxl on 3s. Oh, I've also learned, the vxl esc will only put out so many amps, try swapping it out for a older mm or fuze esc. I easily noticed more speed and gitty up when I switched to the fuze esc.

higher gearing anywhere is going to create more heat not less in this situation.

seriously its already running too hot and you want higher gearing

gear down some and volt up, but your using an axial tranny (and pobaly ax axles too) so that set up is not built for extreme speed, you really need more volts or motor.

also you can not get diffrent gears for the axial tranny, look at the case you really can't get any other gear ratio to work

put a 14t pinion on it and try it. Go from there....

I'm not quite sure what you mean, look at Billetworks Axial based foff rig, that thing is fawking fast, seems to be holding good.

How much does your rig weigh? Mine is at 6.5lbs or so. I run a vxl system with 28/78 Creeper axles with a peed tran. When I can keep driveshafts in it I can hit the lipo cut off and it not hot at all.

im not looking to get more speed out of it, thats not what im asking.. im looking for a way to run cooler. i know that my gear combo is high and will make things hot. im not new to this, i know that the axial trans/ axles are not built for speed. i just thought with all the hype behind the foff movement a small vendor might have come up with an option, since most of us are running basically the same setup. i know that gearing it down will make it run cooler, i have run 54/14. but its just as fast as 20/87. its too hard to tell the difference. i know that what i run now, gets my rig to the top befor anyone else. i ran my setup on a big 2s ( 3 in a row) with no heat issues. maybe ill save the 3s for comp time.

not sure on weight. are you weighing with the batt in or out? i will look into this

[stewbaru]

Higher ? No....

Stronger? Absolutely.

My F-OFF will/has full Robinson Racing trans set.
Steel Wheels, Baby!

Other stuff is gonna break, but not this trans.

I ditched the vxl as it couldn't handle what I wanted out of it...got hot and shut down. Huge difference just going to a mm pro/4 pole system.

[ped453]

hey Paul, I'm running CC sidewinder and 3700KV tekin redline 537 brushless and you know I drive this thing to fawks and the motor barely gets warm, also my rig weighs quite a bit.

So a VXL waterproof motor wont run with an MMP?

[toy4crawlin]

why not use a summit 2 speed trans or a 2 speed auto tran?

The Summit trans is a little piggy.
I'm not sure if you've held one, but it's heavy.
I really like it in my scx 10, vxl, 3s, 2.2 rig though.

[ax10newguy]

thanks for all the imput. i think im gonna go with a cc 4 pole. 6900kv combo. is 6900kv too much? it recommends 2s only, ill be running 35c 5000mah 2s/ will that be ok, or should i go with the 5900kv combo?
