I ordered a set of these : http://store.rcspeed.net/catalog/pro...roducts_id=249
And they are the same as my old ones, my old ones didnt twist or snap with the spool, but they wore out where the pin goes through from the axle.

Has anyone tried these from the NTC3 : http://store.rcspeed.net/catalog/pro...roducts_id=265
Will they fit ?? They are steel so they should last a long time, if they fit.

I've read lots of stuff about people running silver can motors in the TC4, and some stuff about them not fitting and needing modification. Does anything have to be done to make a silver can fit in a factory team TC4?

No the 540 silver can motor will fit straight in the FT TC4 with out any modifications.

The FT TC4 is a very quick car for 540 you should have good success with it.

Whats up Jamie? I have an old pic that you might find useful. Look between the servo mounts and the side of the servo, you will see a clear blob. Thats Shoe Goo.



Its applied between both mounts with the servo upside down, so that some of it can spread between the servo and chassis, and help hold the servo to the chassis when installed. Once it hardens, Shoe Goo keeps the servo from moving in its mounts.

With that said, you dont need to over tighten your servo screws to be sure it doesnt move. Just reasonably snug them down, let the Shoe Goo cure, and forget about it.

I think the biggest differences in the models are the like, where the spur gear is held, and the upper deck. I think most of your parts will carry over though. All your arms, diff cases, hubs, everything like that.

Arrow Question RE Converting to Brushless

I picked up a new brushless system for my stock RTR TC4. Instructions say to change the pinion gear. OK - I get all that. Here is the question - the instructions that come with the Novak Havoc Pro state to adjust ratio to 4.0. Then it says ratios are 'final drive ratios'. FDR...

My delima:

Stock TC4 RTR uses a 72 tooth 48 pitch spur and a 23 tooth pinion.

72/23 = 3.13 ratio

Internal drive is 2.5 so 3.13 * 2.5 = 7.82

What is throwing me off are just the numbers. I figured the pinion adjustment would be just a few teeth (to get from 3.13 with a 23 tooth pinion to 18 tooth for a ratio of 4). That seems like the wrong way though - smaller pinion = more torque and less speed.

If I take the instructions literally and use spur/pinion*ratio to get to 4, I would have a 45 tooth pinion.

Is that reasonable? Understand this is just a starting point. Temp is the key (160 degrees is my target).

Thoughts? Is it really FDR or spur / pinion?

spur / pinion x 2.5 = FDR

Thats at the axle... not including the tire.

If you were taking tire size into account then your answer would be whats called rollout. Thats different.

Are you planning on staying with 48 pitch gears? 64 pitch would serve you better in the pursuit of the best ratio.

The motor cam wont rotate enough for you to fit a 45 tooth 48 pitch pinion on your 72 tooth spur. You need to go much smaller on the spur.

Your ratio of choice will vary as well by motor type, speedo type, and physical motor or ESC timing advance, track size, etc. Telling you to throw on what equates to a 4.0 FDR is a guess at being right.

For my personal 17.5 setup at our local outdoor medium sized track, i mostly use a 64 pitch 81 spur and 41 pinion for an FDR of 4.939. The 64 pitch spurs i use range from 78 to 88 teeth. Pinions range from 38 to 46 teeth.

In your search for the right gearing, try to use the smallest spur possible to place the motor as close to the center of the chassis as you can. The better the car balance, the easier it will be to drive consistently and fast.
