i have a question on the 415 mxs. on the front camber link. the inner stud holes. what does each of the holes do?? i have had them in the #2 hole per setup sheet. what will change( in handling ) if i would move to the #3 or forward most hole. thanks jeremy

Guys,

Just picked up a second hand 415MSX and i'm intending to run it in Stock with a 17.5 BL. It would appear that around 3.5 FDR is a optimum starting point, however to get this I need 50T 48P pinion and 80T 48P spur . Tamiya make the 50 pinion but even if i get this combination will it even fit and is the FDR right.

Thanks

What is the difference between Tamiya pitch pinions and 48P.

I have my 415MRE and as soon as I get all of the electronics installed I will post some pics.

Moving to a different hole effects how much camber is gained as the suspension is compressed. A shorter link gains more camber, and a longer link gains less. A stiff suspension on high traction that pulls lots of G's yet compresses very little may require more camber gain to keep tire wear in the middle. You can also change the link location for both front & rear to alter the balance of traction front & rear in the middle of a corner (or so I think)...

This change also effects roll center, but not as much as messing with the lower arm...

Spacing the arm up & down also effects how the camber is gained. An upper link that's more parallel gains camber slower than an upper arm that points upwards towards the tire. This change has more of an effect on roll-center, but still not as much as the lower arm angle...

Tamiya pinions are metric "module" which refers to the actual height of a single tooth in millimeters. SAE Pitch refers to the number of teeth on a 1" diameter gear (a 1" diameter 48ptich pinion will have 48 teeth). These are two different units of measure and are not compatible...

To answer your question directly, SAE 48pitch is a bit smaller than Metric 0.6mod. SAE 64pitch is slightly smaller than Metric 0.4mod (0.4mod comes with the TRF on-road cars). They can be run together, but won't last to long when you do. The main reason for using SAE over Metric is the cost and availability of parts. Most hobby stores don't stock metric.

The main reason for using small teeth over large teeth is that this gives you more gearing options...

What motor are you using? I'm going to be running a Speed Passion 17.5 but will only be testing it next weekend...

Did you test it to get to the 3.5 FDR? And you do get 64p 80T gears?! ...even where I live?!?! I was thinking of running about a 3.7 but if you say 3.5 I'm going to need another spur...

Thanks for the great answer. I just want to make sure I'm working this out correctly than. I'm trying to get about 3.5 FDR so if I go to Gearchart.com this is 50 pinion and 80 spur, so is this measure on the site in metric. Also the car came with a 78T spur, how do i check what type of module this is.

I haven't put the motor in yet because of the following.

1. I'm lost on the gearing. I don't know what pitch gearchart.com is using for it's calculations on this car.
2. The car came with a 78T spur and I have some other 48P spurs that seem to mesh correctly so I would assume that I've got a 78T 48P spur in the car.
3. I need to get assistance from people like yourself to make the right decisions.
4. Ultimately it's not about the amount of teeth on a spur or pinion as long as they mesh correctly (same pitch). It's about the diameter of each gear and teeth is just an easy measure imho.

To get to the ratio you have what pitch are you using and what sizes.

It doesn't matter what type of gears your using. The gear ratio is the same if you have the same number of teeth. A 50T pinion and 80T spur will give you the exact same gear ratio weather your using 64p, or 0.6mod. The only difference would be the physical size of the gears. Either one will work as long as they fit in the car...

A 78T spur is most likely gonna be 48 pitch on these cars. I would compare it's tooth size some spare gears to make sure...

Damn man well its going to be a week before I run my beauty, so hold on!

I'm going to start her of with a 80T 64 pitch Spur and a Tamiya 51T 0.4 module pinion (I know it'll wear, butwhat must I do?!) that'll give me a gear ratio of about 3.5 and then I'll move down on the pinions if necesary...

So if you can check it out before next week... Please let me know aswell!!!!

But one thing I know is that you do get 64P 80T spurs! Even where I'm from

Goodluck man

I look forward to the next installment. I've tried a couple of online shops in HK without luck so I'm going to try Pro Shop Futaba in Japan. I know they have the pinions, just waiting to see about the spurs.
