Help Me PLEASE! Gearing
OK I am attempting to set up a TC4 for the VTA races. I am having a heck of a time with gearing. I am attempting to get to the 3.5 - 4.0 FRD neighborhood. From what I hear most of the peeps at my local track are in the 3.5 area. I know about the various calculators and have been using them. My problem is getting gear that will actually fit in the space and mesh properly. I started with a 49T spur 48pitch and 31T Pinion 3.9 FDR not enough adjustment to get the pinion and spur to touch, about an 1/8th" short. My next try was going to be 60T Spur and 39T Pinion. for a 3.8 FDR I just checked the 39T pinion and the gear is too big and hitting the chassis. Looks like I can alter the chassis with a dremel, but before I do that I figured I would turn to the interweb to see if I can get some help.
Thanks

I am new at on road and sure to have many more questions I appreciate all the help. OK I know to glue the tire on the bead my question is do you glue the small flap the comes over the tire as well? I did a search and it seems some do and some don't, is there benefits either way?

Getting the correct ratio on the TC4 can be a bit of a challenge.
48 pitch will be fine, 64 pitch is better but not manditory. I use the robinson racing 52T spur gear (White) and this allows me to install a 33 - 40 tooth pinion into the car netting a gear ratio range of 3.93 - 3.25 FDR. You will have to grind some of the chassis webing out below where the Pinion gear will set otherwise a 35 or larger pinion will rub on the webing.
If you need a larger gear ratio (Higher number) You can go with the 66 tooth spur gear and get up to a 34 or 35 tooth or smaller pinion giving you 4.0+ FDR ratios.
I like right around 3.8 - 3.7 ratio range for most track other than really large ones with my VTA car.
Hope this helps!

The OEM tires come on the Sprint 2 from HPI do have the flaps glued...

I run robinson 60t 48p spurs on my TC3 & TC4, yes you need to remove some plastic under the pinion.

Tommy, over in the paint thread asked how people are mounting their drivers and I mentioned there and a while back I would share my technique.
I used some scrap lexan to fold some brackets to hold my figure in the proper place when the body is on. I wanted to mount the figure to the chassis so I wouldn't have to switch him back and forth when I changed bodies.
There are two brackets. One long one in an upside down "u" shape that is servo tapped to the receiver then then up to the figure and then towards the back of the driver to the top deck where it is again attached with tape. I added another one that goes down the back of the driver to the chassis under the motor to help keep him still. The first one was enough but he wobbled around a bit so I added the other one.
The driver is from the double HPI set for their desert truck I think. My brother has the other one. Mounting it this way lets me position the driver where I think he looks best in the car.
