I thnk the ONE WAY that AE selling right now is exactly the same as the YOKOMO one, because AE just brought that 1-way and rebadge it under AE.......correct me if I am wrong.

Talk about 1 way...I just got one from the track...someone that has the FT NTC3 and he doesn't like 1-way, so he sold me the 1way for a very cheap price (brand new)

Today, I tired to put that 1-way on the NTC3....and realized the original bearing for the ball diff DOES NOT fit the 1-way......the inside diameter is aliittle too small for it...

Do I need to have diff size of bearing just for the 1-way...? or FT NTC3 1-way is different then the old ball diff one..?

Thanks for advance....

I dotn know alot but I do know that of its the one way out of the factory team then it does take different bearings than the normal diff, also if you need to buy gears for it you have to get NTC3 one way gears not just tc3 one way gear.

For those stripping one way gears, heres how to prevent/minimize that, i know this works because i tried and experimented for a long time, you need to shim the one way diff gear and the drive pinion as tight as you can, make sure when you replace the broken diff gear, CHANGE OUT THE PINION GEAR TOO, usually when you break the diff gear the pinion is distorted, and the gears are more prone to breakage. Oh yea make sure you use the white gears too, the black ones break alot easier.

IF you do it correctly it should be tough, because i havent broken a ring gear since, more strain on my cvds but i can still finish a race with a slightly bent cvd.

We cured the scraping problem on our first protype chassis, we came out about 1.5 inches on both sides of the shaft with a 4mm flat chassis then we tapered it to 2mm on the sides. this cured the dipping and scraping problems. I can't believe no one else has'nt don the same. A good stainless screw also has a deeper off set on the hex, so they are better, they don't strip quite as bad,

Default The "FIX"

Where can I find the "Fix" The bolt set that secures the front and back suspension.

The tc3 seems sort of fragile. Not that I haven't hit the walls, but it doesn't seem that this car can take much of a hit....

It was listed on ebay....and they keep posting on ebay once in a while, I am sure you will see one again on ebay within a week.

Or simply email the seller, I am sure they are with BMI

Those new cases worked great this past weekend. You can shim the gears up tight w/o binding. I think AE may have finally put the gear issue to bed. The new rear end is also much better, still need to get the two speed parts. Looks like I'll be keeping this car after all. Rear blade SB halps the car rotate in the corners too.

I have the BMI (The fix) for sale, I bought up a bunch last year for all the NTC3 drivers here, but now most guys have switched to the 710. I'll sell them for $10 a set shipped. I also have the BMI ( The nuts) too! $7 a pair shipped. Let me know if interested, PM me. BB

Default "The Fix" or Aluminum Gear Cases...

Which would be better to correct the problem of the weak front and rears of the NTC3?
