RC4WD SCX10 AX2 2 Speed Transmission

[@videobymark]

Thanks for the reply. I have the splined MIP's on mine and thats I thought yours was at first but then I noticed that retaining ring and the square shaft.

[@pyrosrockthisworld]

thats good to hear, am going to have that setup by end of next week if my upper arm mounts arrive for the diffs

[@jimtosh1505]

Nice video able to see function of gear shift

[@crazyashell389]

thats sounds like a good ideal thanks for the replay think i might pick one up

[@balir31]

Hey! I think I didn't get the part when you talk about putting away the lever on your truck... Anyway, at the time of this video, I had the servo on a 3rd channel but the transmitter had no end points... now I have a better radio with end points and it's so much better for the servo..!!

[@eaxebxecxedx]

I ordered an AX2 already, waiting for shipping. Can't wait :D

[@balir31]

It is made by Junfac. Best drive shaft in my opinion, good looking and heavy duty!

[@balir31]

(2nd part of the message...) I use tin to reduce the neutral space. it is difficult to explain but if you know how the trans is made, it is easier to understand... You just have to melt some tin in the holes of the gear wheel, so the teeth of the other wheel that changes gear have less space to move clockwise or counterclockwise. Now I have almost no neutral zone in 2nd gear, and very little (like the stock axial trans) in 1st gear!! now I'm very happy! the process is quite simple!

Scx10+2 speed+ r1 portal axles= 1FUCKING AWESOME TRUCK

[@balir31]

sorry dude, I respect you idea but this is a fantastic upgrade. now i have a reeeeeally slow 1st gear but still fast like a weak scale motor at full throttle, and a second gear that makes it fast as hell (16km/h on my treadmill, and it had still unused power). I know 16 or more km/h is useless on this kind of RCs but this 2 speed transmission gave this model a fantastic min/max speed. And remember, RC is fun, and now I can have more fun than before!

[@balir31]

hi! yes it's a fan over the servo, but I was just doing some experiments. that servo got hot a few times, but it was my fault... I wasn't good in programming my transmitter... now I know a few things more about my tx and the servo do not get hot anymore!

[@balir31]

Hi! it is almost two years now! I'm happy with this transmission and I'm thinking about buying another one for my wraith!! the only thing that could be done better by rc4wd is, this two speed trans has a quite big neutral zone, of about 1/5 wheel round in 1st gear and 1/8 wheel round in 2nd gear, and it was quite disappointing when you need precision, and the car go back or forth a few centimeters. one month ago I decided to open it and see what can be done about that. (txt space over)

[@archerash6695]

Should be slightly rolling when shifting, it's hard on the socket gear corners.

[@jamesdistefanis2183]

Oh, I was just throwing an idea out there. Instead of a servo switching the trans how about a mechanical lever that you can reach outside the body and operate to switch the trans, that's all. I'm still on the fence on how I want to do it. Nice truck, peace.

[@balir31]

ok! now i get that! but I think the switch on the transmitter worth the money you spend for a servo... switching on the run is very useful!!

[@jamesdistefanis2183]

Very nice. I looking at doing this on my SCX10 too. BUT, do you/we really need a servo and 3 channel transmitter to switch it in and out of low/high?! I'm thinking of putting a out of the way lever on my truck. Its never far from you and it would save roughly $150.00 in extras rather than doing it on the transmitter. I can afford it BUT, thats allot of money just to move that switch! :-)

[@eaxebxecxedx]

Is the transmission a direct fit to the scx10? If not, what mods did you do? TIA! :D

[@rapttor4]

Hello, fist of all-nice video.I would like to ask you what turns brushed motor should i use on this tranny.I've been thinking about getting a summit transmission but it seems very big.Keep in mynd that i am going to be mounting the transmission on a scaler so i want it to go slow and smooth.While i can still punch it up trough the 2-nd speed.

[@crazyashell389]

hey so looks like you have had it for a while any problems with the gears and stuff

[@balir31]

Hi! I'm sorry but i can't tell you what you need... I have not much experience in rc cars and on this honcho I always kept this robitronic 2100kv. But i can tell you this transmission is great because it gives you a very short 1st gear and a reasonably fast 2nd gear (I didn't calculate the top speed, but I think it's between 12 and 14 mph with a minimum tire speed of about 1round every 5 seconds!!!!)

[@deriksowlcowski9834]

awsome is it faster than the stock axial transmission in high gear

[@balir31]

yes it is!

[@callumkingunderwood]

This transmission is 5.05:1 in low gear and 1.78:1 in high gear. The stock axial is 2.6:1. So in low gear you have roughly half the speed but double the torque of the stock transmission and in high gear you have less torque but a bit more speed than the stock transmission. Seems a pretty decent upgrade to me.

[@videobymark]

What rear drive shaft is that?

[@balir31]

no problem! those are nice too, but I've never put my hands on it...

[@hybrid5132]

aren't you damaging the gear when it rubs against the drive shaft

[@JaimeRodriguez-rz8uu]

Esta bueno Elias. Cuanto dua una bateria tiempo dura la misma bateria, andando solo en baja vs en alta. hay mucha diferencia de autonomia?

[@balir31]

I don't know... I only use 3s lipo batteries, and they last for hours...

[@CM_ArT_EE]

Looks smooth, could you tell me if the gears in the case/gearbox are metal or just normal stock ones thanks

[@balir31]

the gears are full metal and looks pretty solid. didn't broke nothing yet! and I beat it hard every time!!

[@Andozable]

What pinion n spur number u use?

[@balir31]

Everything is written in the description!

[@davidriggs8026]

thx in advance i messed up my gear mesh and now my spur gear is wearing out and i need to know what spur gear your running before mine dies the one that goes to it is out of stock and i need an alternative

[@dimamiak6438]

Will this transmission fit under the Trail Honcho body?

[@MrFubs]

What transmitter are you using to operate the shift servo?

[@balir31]

I was using a turnigy 9x at the time of the video, now I'm with a sanwa mt4

[@archerash6695]

To bad there's not a step by step video of what you built here and how it's functioning. I've been looking into the same idea. Super bull low

[@varmintsniper2551]

I run a Traxxas slipper and gear set up. Works better and reduced the noise a lot.

[@balir31]

yes, it is 99% plug&play!

[@ryanwest7060]

Just broke the meat output shaft on mine only ran it 4 or 5 time over that that it's a wicked transmission just don't run it on brushless on 3s and you should not brake any think like I did

[@balir31]

it is almost two years I'm using it and I only use 2100kv brushless motor on 3s, with 115mm tires, bashing it all the time... I'm using junfact carbon shafts, the plastic ones were gone long before I bouth this transmission...!!

[@balir31]

ti piace??

[@GiOrDyCrE]

si dado

[@GiOrDyCrE]

lol

[@EcoAlkan]

an unnecessary work and unnecessary for the scale crawler vehicle

[@jimtosh1505]

Hi what Servo did you use and arm for shifting

[@balir31]

Sorry can't remember. Now I'm using a plane servo, the ones that are slim
