how much she cost?

$110 shipped. Has the slightest pawn shop smokey smell to it.:sleep:

Would a jato .8 mod (I think that's 32p) work?

Servo city sells 32P spurs. I have a 44t 32P spur in one of my pan cars. The GENX 10 of mine uses a Traxxes 54T 32P spur. I just drilled out the center a bit to make it fit properly.

The diameter of the spur gear on my tc3 is about 40mm. what's the diameter of your 44t spur?

Dunno man. Dont have the car here with me. Figure that 44T 32p is equal to about 66T 48P. BrainG has the gear diameter calculator. 44T is equal to 36.5mm.

44T 32p spur is 36.51mm diameter.

Doh, I just edited mine.

Awesome. Do you know off the top of your head what pinion you are running?

I use pinions from 9-12T count. With bigger pinions I use sensored/hybrid mode.

I'm thinking I could use what I have - My medusa 36-60-2000. yeah baby.

Gearing. I found if the spur/pinion are the same size, I should get around 88mph. I think 32p 44t pinion/spur should work; problem is finding the gears.

How can I make an adapter to run a spur for my pinion?

The smallest 48p spur that I have seen is 46T, but it's doesn't have those diffballs holes.

If you mesh the gears right you will not strip the 48p.

I don't strip gears. But I hate swapping in new spurs when little rocks get in between the mesh of 48P gearing and locking up the motor.

I'm not worried about gear mesh, but more my shaft size. I've got a 5mm shaft and 32p pinions are easer to find for a 5mm shaft; or can you find two equal tooth count 48p gears, the pinion with a 5mm shaft, the spur fitting in the tc3, and the two shafts about 35mm apart?

here are two cheap gyro's (i have the second one in my rustler)

Drove the car for a couple minutes with a 8-cell nimh pack. Don't have a charger for that pack so once it's gone its gone... It drove pretty good and it was pretty fun even at not so quick speeds. Once I split my 4s zippy I'll have a copule 2s packs I'll probably run in a parallel so I can still run them in a series later.

Temps were ~110-120 both on the motor and esc; battery was cold. I think the front diff is stripped or loose; I'll take it apart probably tomorrow or later tonight. I'll clean off my work bench first. :oops:

The TC3 and TC4 have the same drivetrain. It will hold the power......

This battery fits fine. The above car in the vid is running the same batt but in 4S.

Are you the shooter of that video? That Channel? I've watched a bunch of those speed run vids... Any tips or tricks?

Negative. I was the one radaring it. I was actually the one who came up with the setup 1 year and a half ago working with some help from CC. We have been running high spped cars for several years but I wanted to build a 100+ car with 100% off the shelf parts. Nothing custom!! The TC4 was the ticket!!

As far as tips, all I can say is that the power is available. The key is the setup of the car. Suspension and body choice are very important!!

By the way, what "Channel" are you refering to??

That Miamiz finest channel.

AHHH!!! That is the car's owner user name. He frequents RC Universe.

Well, I made some headway today. I got a Quark 6000kv motor from linc and soldered it up. I think the pinion is around 26t. Once I plugged everything in I lifted it up and tested it with my 9.6v "test pack". It worked fine so I plugged in my flightpower 3s lipo. It worked too. My friend was over, and I decided to show off what a 4s pack would do. I gunned it and parts went flying everywhere! I ended up snapping a drive cup and bending a center shaft into a boomerang.

After that I thought I'd test it with rear wheel drive and the 3s lipo. The car we really slow and made odd noises in the [ball] diff. We took in it and after a few minutes we had the diff out. It seemed a little hot, so we temped it and it was at 160f! I guess the diff was slipping. After trying a few different things and stripping a ball diff screw, we took the balls out of one a took some CA glue to it.

Now I esentially have a spool I plan to put in the front after I get a new center shaft next week. I ordered it today when I picked up my ball diff rebuild kit that had the stipped screw in it.:oops:

With the spool in the back it spun out, a LOT. I couldn't get up half speed. it was embarrasing when a cop drove up and asked us how fast it was. I couldn't get it past 20mph! Well, I hope I have better luck with 4wd. I'll probably post up some pics but until then I'll update ya'll when I get some good runs in with 4wd.:party:

Well testing is identifying failures- your diff is one of them. Hope it works out for ya.

I *hope* the diffs hold up when there is 4wd. RWD must be too much for a ball diff with so much power behind it... I expect the diffs to do fine but your post will forever haunt me...:eyes:

This may be a bit off and odd, but could you also use A123 cells and if so is 10c good enough or do they make higher C packs or higher then 2300mah?

a123 cells should be rated 30/60c. The ratings are different then lipos however. It is rated to how much current the cells can survive. The a123 cells don't hold their voltage under load like a good lipo will.

And for an update on the tc3, the parts were on order and I went to pick them up and everything at the hobby shop was being packed up. errr.. I was pretty good friends with the owner and now I have to drive 30 minutes just to get parts. Maybe I can pay for shipping and get them online.... But the parts aren't in yet so no progress..

Ok just wondering since I've been using some old nimh sticks on my tc5 but the area for the batterys have 2 peices of plastic that are screwed on and are basicly shaped to hold a custom "cell pack" like nimhs or a123's and since my nimhs are almost dead and I'm tired of the packs sliding around I was thinking a 3s3p would be nice , cuz it would fit perfectly, and it would be 9,9v and if I managed to get a MM 7700 I could "theoreticly" hit 100mph, but the fewest and least expensive cells on fleebay were 2300mah 10c, 8 for 68$ shipped.

FINALLY pic. Has the flightpower evo30 3200mah 3s lipo, quark 4t motor, MM, and an external bec in there. Note missing driveshaft. :oops:

Looking good....few things:

- You need stiffer springs
- Sway bars (rear for sure)
- Definately foam tires!!

That should help you keep a handle on the car. By the way, what body are you planning to run??

Clean your RX wiring-
Also your tires are on backwards.

Thanks. I'll put those on my list. I'm running the mazda body on the previous page unless you guys can find me a really aero body.


Thanks Ian! :angel:

:lol: I like your motor wiring.

Yeahppp I got lucky on that...:smile:
