to bill,
hows the speed of your new reduction gear box? is it more realistic to tiger I's speed?
cuz am planning ordering from you again.. but my bro will be doing the ordering for he owe me in shooting range contest.. =)
just want to know some info of your new reduction gearbox.

thanks

Hey Daryl,

The new design reduction gearboxes have about a 30% reduction in speed over the stock gearboxes - more quiet and lots more torque.

Are these 3:1 gearboxes made of steel like your black ones? And what motor do they come with?

thomasjohnmurphy

does Bill have different speed reduction gears other than the 3:1 reduction unit. You will need Speed 400 motors with the 3:1 unit to give it a more realistic speed (and lots of power)

chinito_03

thanks bill.

@thomas,
so any site where i could get the 400 motor?

daryl

Thanks to everyone for your comments and interest. Save your money! With the new style reduction unit you don't need the Speed 400 motors. The white capped motors are ideal with this setup. There's a post that shows the different motor rpm comparisons; however, I'll post some real rpm comparisons within the next few days of the final drive speeds, which is the additional information you need to make a knowledgeable decision on which route you take when it comes to scale speed. The torque from these new gearboxes is a non-issue as there's more than you'll ever need (unless you're using your tank as a stump puller).

Bill,

Do these new transmissions use the steel gears? If not, will this be an option later on?

Thanks,
Dan

Hey Dan,

The ones on our site now are metal gears. We'll be adding reduction gearboxes with steel gears soon (actually expected to have them by now but have had a couple of delays getting the steel gears back in stock).

"Metal gears"...are these the same reduction gear boxes as Asiatam's, which use the same metal as the basic metal upgrade? (requires extensive break-in, etc) I guess what I'm asking is what kind of metal is it? I guess I assumed these were the awaiting steel gear reduction boxes.

I can tell you guys these gearboxes are awesome. Since I have one of the first sets of STEEL geared reduction boxes from Bill. They are quiet , powerfull and much closer in scale to a Tiger I. Sorry Bill, i'm gettin as bad as bubba. couldn't keep my mouth shut. LOL

here are the pics of the altered gear boxes

@ bill

nice... so your new reduction gearbox doesnt need 400 speed motor.. nice nice nice..
ty very much for the info..

ive been waiting for those 3:1 steel boxes, cant wait, theyll compliment a tank for sure.

If someone can post the tooth count of each gear I'll add it to the Gear Ratio Calculator. Anyone interested in this Excel file can PM me with your e-mail address and I'll send it.


The Tiger with White Capped Suntech motors moves at nearly scale speed. In the old days (2003-2006) most Tigers had black capped motors which moved the Tiger at about 2.5mph which was about 1mph faster then scale speed.

bubbajoexx

with bills new reduction boxes the final output shaft speed with white cap motors is 170 rpm and stock speed for a white cap gearbox is 268 rpm

philipat

My math might be off...that would seem to slow it down way below scale speed. Trade-off is more climbing power and off-road power, Iguess.

swathdiver

Certainly slower then stock but would be realistic as a maximum off-road speed. Either way the torque will be appreciated. Maybe Bill can post the tooth count so we can put his gearbox in the Gearbox Calculator excel file?

bubbajoexx

the new gearbox turns faster than the asiatam 3:1 and is faster than Bills old 3:1 that was 70 rpm the new box turns 2/3 the stock speed

philipat

Cool...so are the motors different between Asiatam and Bill's old gearboxes versus the new one? I would think that if the reduction is the same, the only way to get a faster (or slower) final drive speed is to change the motors. I suppose the other difference might be reducing significant friction points (proper gear alignment, bearings instead of bushings, etc).

Sounds like a really good setup, just curious about the differences. Also, these gears are made of steel, right?

bubbajoexx

the asiatam use 5 gears and bills new box uses 4 gears only its not the motors that are differant its the gear ratio that is corrected to give the proper speed

there are a few metals left but the nex bunch is steel gear only

Ern

Bubba, so are you saying that it is unnecessary to change the motors with the steel geared 3:1 gearboxes? I was going to order the plain steel gears to avoid messing with changing motors and such, but will definately get them when they come in if they do not run as slow as the metal 3:1 that I have seen video of.

bubbajoexx

they are much quicker than the metals and better built with the steel gears

swathdiver

Looking at Bill's gearboxes on his website it looks like he's replaced the 45/15 tooth gear with another 53/15. Can anyone confirm this?

This would give a modest reduction in speed and more torque. Switching to an 8T pinion would put the reduction in the mid 50s range.

It's been a while since visiting your website Bill, it looks great! When my recreation fund gets funding I know right where to go now!

Dongskie

Wow!

My Tiger1 will love this reduction gear..

More power to RCCommand!

RCCOMMAND

Hey guys, sorry for the delay. Yes, one side of the gear has 53 teeth and we've machined and then incorporated 15 teeth on the opposing side of the gear.

Thanks for the kind comments, James.

Bill
