All of cam/mount related work is for allowing more motor rotation to allow for larger pinions. The work on the cam itself is required to allow the cam to rotate enough, the alignment ridge hits the motor clamp.

Thanks for the feedback. I have a lot to learn about programming ESCs, it's a whole new field for me.

yep, just found that out. I had only dremeled one side of the cam. tweaking mine now to make sure I can tighten down the motor clamp w/o the mess tightening up.

The simplest (and probably cheapest) way to reach the 4.2 FDR for a TC3/TC4 is to use an 84 tooth spur and a 50 tooth pinion in 64 pitch. This is exactly 4.2. If you plan on only running 4.2 you would only need to buy 1 spur and 1 pinion.

84/50 * 2.5 = 4.2

If you use a tub chassis TC3 you will have to remove some of the webbing or chassis support that will be underneath the pinion gear. I just setup a TC3 for VTA and used a grinding stone/wheel on my dremel and it only took me a few minutes to remove the material so the pinion would not rub the chassis.

The smallest 48 pitch spur that I'm aware of is a 60 that is made by Robinson Racing. It is available on Tower Hobbies (http://www3.towerhobbies.com/cgi-bin...?&I=LXEY18&P=7). The "fastest" you can go with that gear is:

60/35 * 2.5 = 4.286

so with the 84/50 you have enough play for proper gear mesh...without having to mod the motor cam (only mod'n the 'webbing')??? I'm just trying to confirm and help some other locals who are trying to gear a 21.5 My gearing 88/52 did not fit w/o grinding on the chassis and the motor cam.

Also has anyone ran the 48p 60/35 yet? Any fitment issues? I'll probably go to 48p when we go outdoors as I had 64p get eaten by the pebble monster too often.

On a TC3, the 84 spur 50 pinion should fit fine without any modification to the cam. I've run this combo plenty of times without needing to mod the cam. If I remember correctly it is a tight fit, but it works just fine.

thanks. I'm putting together a TC3/4 page on my local forums for new racers (all wanting to get into VTA!) w/ TC3/4s and just wanted to confirm. 21.5 gearing is my current topic!

If anyone can confirm 84/50 to fit into a TC4 tub chassis with or without the cam mod required please advise! I'm pretty sure the 3 & 4s are close enough it only needs the webbing gone, but looking for confirmation before I put it on paper.

Anybody else confirm the 60/35 48p fitment? Seems like they would but a 60t 68p spur has to be pretty small.....

Appre'cish.

slight dremel work needed for the 60/35

If you are doing a 69/41 combo on a TC4 with the metal heatsinc that runs along side the motor you have to dremel the whole length of it so the motor can slide over. Other than that the previous pictures on this topic work great.

Get some of the tube that comes with the losi glue, or one of the extension tubes from a hobby store. Usually, just gluing the "flap" area on the front of the tire works well. The backside you do as any other tire.

Strip any finish off the surfaces to be glued on the rims before you glue them. The chrome and silver satin will peal away with the glue if you don't.

Here's my CAM mod for the tc4 tub chassis for fitting 52t pinion with 88t spur (64p). I didn't have to touch the motor mount, only the cam had to be dremeled. The motor is close to touching the motor mount but clears and have plenty of room for proper mess. Some of the 'webbing' has to be removed on the chassis for the pinion to clear.

88/52 * 2.5= FDR 4.23

Guys running TC3 in VTA class -- what are you doing to get the front end down to 5 mm ride height ??

Even with the spring collars backed off all the way, I can't get below 5.5 or 6 mm ???

Thanks !

I like your signature quote above, but you should add "and a six pack in the back"
