Can someone explain to me what a "spool" is and what it does?

A spool connects the opposing axles together so that they turn the same direction, at the same rate, all the time. It works great when you're running in a straight line. But when you make a turn, either to the right or the left, the inside tire usually scrubs off some material. Shortening the life of the tires.

Also the spool let have lots of on-power steering..!

First post ... Great forum ...

I've been racing a TC3 (almost) FT since early November and LOVING IT ... thanks to all who post here for their input / experience.

Now for my question ...

I have read alot about the NTC3 steering mod and am very interested. Does anyone have pictures of this mod??? I apologize if they have already been posted but have not been able to find pics after dozens of hours of reading ...

its already been posted in this thread so you need to go back several pages and look for the pics

Any idea of an approximate page number?

whats it worth to ya?? LOL

page 104 lazy!!

Hi guys. Greetings from Malta.

I don't understand all the fuss about diff outdrive wear.

My son has raced a very competitive TC3 in mod for the last 3 seasons. This season alone he has so far won all 8 rounds of the National Championship. In yesterday's round he actually lapped the second placed TC3. So he is quick, and so is the car.

I wasted my money last season on titanium diff outdrives. The wear on these was so alarming that I had to put the stock AE plastic ones back on after just 2 rounds of the championship.

So we are back on plastic outdrives. At the beginning of this season I put a set of titanium drive shaft assemblies on. Again I am going to have to replace these before the next round because they are just about to fall apart with wear.

In the past 2 seasons of racing we used the stock AE alloy drive shafts and never had any bother. I start a new season with new ones just as a precaution. So it will now be back to factory parts for us.

There is very little wear in the factory alloy drive shafts, and even less in the plastic diff outdrives, and these are so cheap to replace that it has got to be the best way to go.

Oh by the way. The only maintainance is a spot of oil before a race weekend, and wash the whole lot clean after racing. I have never needed to dismantle the diffs in 8 championship rounds of racing, though I will do so now, at the half way stage, to change the driveshafts back to stock, and to wash out and regrease the diffs.

TC3.1, designed by me!

designed by you huh?
looks like K. Factory parts to me?

No, seriously it's not. I did it all myself with basically no other influences from designs of other companies creations other than yes, K-factory style top deck. But I designed it all myself. Please beleive me.

I had the chassis cut from my local laser cutters beacuse to have it CNC'd would have been too difficult since there aren't any in my area.

My friend who is very good at machining alloy cutom made the motor mount and posts directly from my design.

I'm really happy about the project and i hope it goes well once i have it all together etc.

Enjoy!

well if it is homemade it looks really good!

Anyone using the IRS chassis including the stiffeners on the sides? How rigid is it compared to the graphite tub chassis? Thanks!

i have the full IRS kit, and i think the chassis is fairly stiff, but a little flex is good too!

Northerner, who sells that top deck?
