I haven't gotten my kit yet, so still haven't run the car. From what I've been told, cutting the motor mount is the way to go for asphalt tracks as it makes the car much easier to drive. I've ordered a spare motor mount as well though, so when my kit and parts arrive I'll be able to give more hands-on feedback.

You have to try it to see if it suits the track you're on and your driving style.

Do you run on one track or multiple? Do you like to tune your car all day or drive it?

I run mostly on high grip asphalt and did not like the cut mount, I felt the car had more overall stability with it uncut and more mid corner speed.

Randy where are you going to run mostly? WCRC?

Most likely will be running at WCRC and TQ Raceway. Tamiya USA's track for practice if a bigger outdoor event is coming up.

I would run the uncut mount first and see how that goes.

Then I would try the rubber o-ring trick under the motor mount.

Then try a cut mount.

eh? Unless your happy to machine away a load of material, no way your gonna get an o-ring under the mount.

Now, if you mean rubber o-rings under the top deck screws, then I follow

Hi, quick question (hopefully)...

What are the differences between the 416WE and 417 front and rear bulkheads? Is it the height the top decks are mounted - if so any idea on the height difference?

Despite the new bulkheads on the 417 am i right in thinking that they are spaced the same so that diffs etc can be transferred from model to model?

Thanks for your help
Chris

The bulkheads are not spaced the same, they are closer together, but the 416 diffs still fit

I used to do it on my Ta05ms to get grip outside (the chassis is very stiff).

Two ways to do it.

1) You can fit std o-rings between the top deck and the aluminium parts (bulkheads + motormount) and screw it down. This gives you more flex. You will need 12 soft O-Rings.

Simple more flex solution, costs pennies.

2) you need 13 O-rings. Firstly put 5 o-rings under the motor mount, between the mount and the chassis and screw them in. Then on the top deck fit the 8 o-rings between the top deck and the bulkheads. The 4 remaining screws attach the top deck to the motor mount without o-Rings (to offset the bottom O-rings underneath).

It raises the centre transmission up by 0.5-1mm depending on what o-rings you use, but allows the centre to twist more.

You have to take care that each screw is squeezing the 0-Rings the same amount, also use the same type of O-rings or you will have different tolerances.

I Dont race Mod only 10.5t and don't profess to be a pro, but it worked a treat on my MS on Tarmac. I have fitted it on my 417 as a test but not had a reason to race this set-up yet.

Oh and don't use aluminium screws as they will strip as you need to use a fair bit of pressure.

Default Rookie 417 setup sheet question

Guys:

For the shimming of the FR suspension mount (reversed), all setup sheets that I've seen thus far state using between 0 and 0.5 mm shims in this area.

When looking at the instruction manual, there are two shims used, one 3mm and another 0.5 mm. Does this not equate to 3.5 mm? or it the 3mm considered a spacer and not shim?

Appreciate your responses.

Thx!!

Hey guys new to the 417, couple questions:

Top 2 things i need to do out of the box?

Are gear diffs needed both front and rear or just one side of the car to run 8.5t mod?

Thanks again!
