fmglass - shoot me a price on that USA-1 if you still got it

USA-1 · #**427** 04-12-2009, 03:07 AM

So- does anyone have a solution to replacing the counter gear on the usa-1?Kyosho doesn't make one (part # BS-84), and so far the internet has turned up nothing.I was however able to order the ring and pinion for this truck. I have two sets-(BS-121). Wanna trade for a counter gear? There was talk of the "Traxxas EZ Start 2 & Related Parts Gear Set" as a replacement.I bought it - Not even close- Don't buy it! Any advice would be appreciated. You can't tell me that everyone has thrown out they're USA-1 trucks because they can't find a counter gear.Please Help!!

try giving these guys a call... ask for Jesse.. he has a large collection of USA-1 and Burns parts in stock... probably one of the largest collections of parts anywhere.. http://bmihobbies.com/
Tell him Rich from NJ gave you the info...

Try with a 11t pinion, might require new motor mount though...

Or try getting the main gear from a Thunder Tiger EK-4, that will require a lot of modification to make it fit properly...

Anyone know where I could find a new spur gear as this one has stripped out, even better anyone know where to get a metal one, or something that can be adapted?

DCLXVI · #**431** 04-30-2009, 01:52 AM

It won't be easy to adapt a gear from another car since that spur is moulded in a quite perculiar way...

But if you are not afraid of ordering from abroad I can give you an adress to a Japaneese store that usually have old stocks...

I'm at work now and I can't really remember the name of the store (something like Iishimokei)...

Hi,

see the photo below and follow the steps:

BS11 is here: http://shopkyosho.com/product/part_number=BS11/410.0

BSW19 is here: http://shopkyosho.com/product/part_number=BSW19/410.0

BSW34 is here : http://shopkyosho.com/product/part_number=BSW34/410.0

here is my USA1 with the same set up using BS11:

USA-1 · #**433** 05-05-2009, 12:36 AM

They no longer make this part "BS-11". Any better ideas genious?

marwankw · #**434** 05-05-2009, 04:51 AM

I'm assuming that you emailed or called Kyoshoamerica regarding the BS11 and they told you that it is no more available cause the link says "Limited availability"

the next option is getting a 48t spur from here: http://shopkyosho.com/product/part_number=IFW58/410.0

or here: http://cgi.ebay.com/KYO-Kyosho-KYOIF...%3A1|294%3A200

you will need also a center diff housing : http://shopkyosho.com/product/part_number=IF26/410.0

now the above set up is using a 48T spur instead of the standard 53T spur, which calls for using a bigger clutch bell (17t or 18t) which required a stronger engine. The late 80s engines were not able to use the above set up since their HP was around 1.2 to 1.8

but todays 2+ HP engine should have no problem.

I hope the above helps.

Thanks for the advice! Just a few questions.. Did you have to move the motor forward to meet the spur gear?... Why do you have to reverse the direction of the front and rear diffs? ....Is the truck "wheely happy" now?! Thanks again for your help

marwankw · #**436** 05-06-2009, 12:45 AM

hi,

1- you don't have to move the motor forward, the setups I mentioned are taking care of this, the spur gear itself is thinner in the overall thickness so it will adjust it self.

2- the original setup includes a counter gear between the spur gear and the clutch bell, so if you remove this counter gear the rotation direction have to be adjusted by reversing the front and rear diffs.

3- USA-1 is not a wheely truck, so I don't see any effect except the ones I mentioned in my earlier post about the requirement of a strong engine.

see the USA1 and other Kyosho old trucks promotional video here:

forward to 1:05 for USA1 Nitro Crusher.

Hello,

I was trying to find a carburettor for my Rc and found this forum. I have a almost brand new stock engine Nitro Crusher with a broken carb needle. I assume that you ppl might have the knowledge to help me to choose a replace carburettor or spare part? The difficulties of the task lie in that i live in northern Finland, meaning that there are no rc shops or knowledge of any kind. I can order all the needed parts via Ebay only. Thankyou, sorry for the bad English!

DCLXVI · #**438** 07-24-2009, 12:10 PM

I'd recommend a new motor, it's quite pricey but it is well worth it...

Here's some webshops I've been dealing with that are good...
www.towerhobbies.com (USA)
www.modelsport.co.uk (England)
http://www.ishiimokei.com/ (Japaneese, somewhat tricky but good prices on Japaneese stuff, very good for older Kyosho and Tamiya stuff)
http://www.rcmart.com/catalog/default.php (Hong Kong)
www.rmf.se (Swedish, basically my local shop, it's right on the way to my work, should be able to send to Finland, has alot more stock than shown on the page, will be able to hook you up with everything you need if you call them)

I'd recommend a OS .30 motor, should be pretty good...

EDIT: I might be able to hook you up with a CNC'ed aluminium radio plate for about €15

iNSTAGOD · #**439** 07-25-2009, 06:25 AM

ive been thinking about a new motor aswell, but need to get the old kyosho working before buying a new one. the carb doesent need to be orginal. thankyou for the websites ^ very hepful.

TFLA-USA1 · #**440** 02-26-2010, 02:41 PM

Well it's time to get out of the USA-1 business. Just listed my truck and all accessories on Ebay. Don't miss out if any of you guys are looking for some NOS parts.

USA-1 · #**441** 05-05-2010, 02:48 PM

Does anyone know where I can find a counter gear for the usa-1?? I have searched for months and kyosho stopped making them long ago- I have cash or could trade. I have two sets of brand new diff gears if someone wanted to trade .Thanks...Craig

Dudeman82 · #**442** 06-20-2010, 02:42 PM

Clearly not many people yap on this usa-1 thread. What a bummer

I just melted my counter gear the other day and have been looking everywhere for one. I guess this is the downside to owning and running a classic truck.

So looks like everyone has the same issue with this truck as i been reading, just a weak counter gear. You would think by now someone would have come up with a replacement, or some guy with a cnc machine.....

The pic above where the guy eliminated the counter gear was actually my first thought, but i think torque loss will be a huge factor. Anyone else done this?

gixxer · #**443** 07-05-2010, 09:31 PM

Wow, my thread is still alive but my pic of my truck is gone

. The counter gear was a problem back in the day but luckily i ordered spares.

I have tried my RXB setup with the USA1 with an Inferno center diff setup. The RXB did not have enough torque to move the truck but with today's .28-.30 it "might work"? If it does i doubt it would accelerate very fast.

Of course we have, just flip the diffs front and back. The truck does about 40mph this way. Torque loss is not a HUGE factor but it does exist. Cant have both. The gear was a con, but like the original poster said, if its installed right, it runs without incodent. Mine used to pull a cinderblock down the street... I had a trailer that carried a VHS camera. Even dragged it on the beach once. At the cost of the camera which had to be professionally cleaned. Too bad the tape dissapeared, it was some great footage. Yes I am once again, looking for the counter gear made of steel, and to see what all lives about this truck. But I prefer the Higher gear config, and I have even removed the front dogbone just to get it to drift and stuff.

People can say how insignificant this truck was all they want. Its the first ever heavy duty MT that ran circles around anything in its class even though it was a BurnsDX with bigger tires. Mine still runs 20+years later, and I plan to dust it off and run it before Summer ends. Body, Shocks, steel gear(s), engine and radio, batteries and fuel. Should cost around the same as what this truck originally cost me lol. Its got bearings and a custom body mount hinge, fliptop tank and a water tight radio box. Its existing engine and radio probly still operate, but I want to budget them in. This truck was last seen running on youtube, some years ago and has recieved 7,000+ views.
Newer trucks probly have light weight and state of the art gears and parts, but what makes this truck transcend time is it's resilience to change. As long as you can bolt parts on it, this kit will always be an RCMT.

Now I got to study this thread and find what fits where for gears and stuff.lol

Hi All,

If I am able to manufacture a Stainless Steel BS-84 Counter Gear, How many of you are interested?

The more people willing to purchase, the less cost it will be.

oosh123 · #**447** 10-17-2011, 03:19 AM

Hi,

The Counter Gear is not ready yet.

It's been manufactured and it will arrive to my door steps in 4 weeks or earlier.
