Yes all those gears are readily available

The internals on the TB04 and Evo6 are identical. What most TB04 owners have done was change the large gear from 40t to the 39t that was used on the Evo3,Evo4 & Evo5. The 39t gear from all those chassis will work. To go even further. Change the small gear in the gear boxes. Using the Evo5 small gear 39/16 will give you an IR of 2.4375. And using the Evo4 small gear 39/17 will give you an IR of 2.29. There will be some sanding and adding shims in front of the small gear when your done to make this modification work. If you do it properly, the drive train is extremely smooth.

I've run 70/63 in 12th scale

Xenon is coming out with a 68t spur as well

I believe crc has 64p pinions in the low 70s.

Juan Aveytia

55t pinion is all you would need. 72 spur. And change the internal gears

I know you mentioned 48p-
What I use for spec. I'm sure you've heard of them;
Robinson Racing 48P Pro Machined Spur Gear (60T)

Robinson makes even smaller if you need and can be ordered from many online sources including ebay and rcmart

They also make HUGE 48p pinions- 47t is the biggest I believe.

Kentech or red bull. Both of you seem to have lots of knowledge with Tamiya's and other stuff. I want to buy a floating servo mount for my 414. The Tamiya 503 has some parts that I think will work perfectly for me. Could either one of you help with the correct part numbers to from this car. I need everything to make the floating servo mount and split battery pack holders. All help is appreciated

You've got two problems with the servo mount from the 503

A) it's an 8 digit part (well, two parts plus a tree piece actually) so not easy available
B) it's keyed to the chassis

The 418 and 417v5 are single pieces but also keyed.

You would possibly be better off making one from some butchered servo mounts and a little ingenuity.

Juan Aveytia

Thanks, but I want to use original tamiya parts. Keying it can be done. If there is (2) screws I will just cut the key area away. Any help will be greatly appreciated

Here's some info:

- 9114087 J Parts (you need 2 of these)
These are the battery holder plastic parts tree, so it has the locators that go on the lower deck as well asthe plastic hold downs.

- 9804800 Battery Post (you need 4 of these if you want to use posts and a hold downs instead of tape)


Servo mount:

- 3404035 Servo Mount Bridge
This is the carbon part of the 503 servo mount.

- 3454971 Servo Mount
The inner alu post (keyed both top and bottom, 2 screws that go into lower deck)

- 51278 TRF501X K Parts (Bearing Holder)
Just the normal 501 plastic servo mounts that are used at the outer end with this solution.

Hope that's the info you needed. Of course you need some normal screws, shims etc. too.

Attach manual pics of the parts needed:

As mentioned you willhave to key the chassis with those parts. CSO does a floating mount for the 417 that is not keyed.

Juan Aveytia

Thanks from everyone for the help. Oatmix, can the mount be reversed. The 414 servo is on the opposite side from the 416/417/418?

Qatmix

Doh! Yep I forgot about that. I will take a look to see if it can be reversed in the morning. (I will try to see if it fits on one of my 414's)
