Answers
1 How do I get the RC10T3 to sit higher off the ground?
Read the back pages of your manual in the section about “ride height.”
2 Several off road racers at our local track have stripped the servo gears on
their T3. Even when the servo saver nut was loosened to the maximum, servo gears
were still being stripped.
Try this:
1 Disassemble the servo saver assembly.
2 Take the upper arm of the servo saver (part number 9155) and file down the
lower edges so that the bottom of the V is more rounded at the edges. You only
need to round the edges, not the entire bottom.
3 Prior to assembling the servo saver, place a small amount of black grease on
the lower servo saver arm (at the points where you modified the upper arm). This
will help the servo saver mechanism to pivot and function properly.
3 Would you be able to give me a part number for a set of springs that I should
use on an oval asphalt track or what kind and size of springs?
The FAQ link shows a list of all the springs available. I have a setup for dirt
oval you might want to try. At least that will give you a starting point.
Left Front:
Blue spring #7429,
60 weight shock oil in both with #3 piston.
Right Front:
Red spring #7430,
60 weight shock oil in both with #3 piston.
Left Rear:
Green spring #6480,
45 weight shock oil both with #1 pistons,
10° front block carrier #6212,
0° block on right rear hub carrier #7366.
Right Rear:
Green Spring #6480,
45 weight shock oil both with #1 pistons,
10° front block carrier #6212,
0° block on right rear hub carrier #7366.
4 Is there any way I can make a bigger pinion fit with a smaller spur to make it
go as fast as it can?
To get a bigger pinion, go to a smaller spur. With a smaller spur the motor will
accelerate faster. You might lose a little torque, but you'll get a bigger
pinion on the truck.
5 The pin in the CVD keeps sliding out about halfway.
You can file a small notch in the pin so when you tighten the grub screw down it
has a flat spot to catch on. Or you could take a piece of shrink wrap and put it
around the part of the CVD were the pin is and heat shrink it tightly around the
CVD.
6 What can be put on the tires of an off road truck to prevent medium to hard
pack clay from packing on the tires?
Pam™ cooking spray. It's messy, but it works.
7 When you tighten the slipper clutch will it cause the wheels to slip or not to
slip?
When you tighten the slipper clutch nut it will cause the wheels to spin more.
If the slipper still slips than you might want to check to see if the slipper is
built properly or it might even be that your differential isn't adjusted
properly.
8 I have the team kit version of the T3. The slipper clutch on my truck slips
too much, giving my truck very little torque. How can I solve this problem?
An easy way is to glue the pad to the inside slipper hub. Do not glue it to both
hubs. By gluing the hub it will allow you to tighten the slipper less yet give
it the torque to do the job.
9 I was just wondering if u could help me with a setup for indoor carpet racing
with my t3. also how should i gear my 11-13 turn mod motors in comparison to off
road.
Start with the kit setup and lower the truck as much as you can. You may start
"stiffening" the chassis setup by increasing the shock oil weight and/or
increasing the spring rate [go to a stiffer one] until the truck is going faster
around the corners and isn't leaning so much. Just start experimenting AFTER you
have the base setup working.
10 I am looking for 0 degree a arm mounts for a rc10 T3.
All of our testing showed little to no benefit in running 0 degrees. If you must
try it you can use a 3 degree block and turn it around. You will have to do some
modification that is lengthy to go into here but it will be obvious when you try
to do this. Good luck!
11 My question concerns the pins that hold the front suspension arms on.....the
e-clips on the back side of the pins come off almost every time it is ran.
Turn the clips so the round part is facing down. That should help.
12 Which MIP CVD Kit would you recommend for the T3 Kit, the shiny or the
aluminum.
I personally would recommend either the standard CVD’s which we sell or the
Shiny version. I personally do not think the aluminum dogbones will last very
long due to the amount of travel the truck has. The advantages of the CVD’s over
the dogbones and stub axles is a slight improvement in efficiency--only one
part, so if the rear tie-rod comes off you do not have to look for a lost
dogbone, and because of the smaller axle design (which we cannot use with
dogbones) the rear hub bearings are stronger and last longer. The difference in
acceleration would be impossible to tell.
13 I went to a new track this week end and i was fast but the back end of my
truck seamed to be faster the me through the turns....it wanted to pass me!!!! I
tried shorting the wheel base, different oils, and moving the battery around.
The track was hard and dry and dusty.
Try raising the front ride height a little and lowering the rear ride height.
This should give the truck less steering and more traction. Tires play a major
roll in traction as well, so finding the right tire for the track condition is
very important. Also, stiffer front spring and a softer rear spring would be the
way to go to gain more rear traction. These are just some things you can try.
See what other people are using for tires.
14 The suggested max gearing for the T3 list modified motors from 10 through 14
turns and stock motors. How should mild modified motors (15 through 19 turns) be
geared?
For the T3, 15 to 19 turn motors should be geared as follows:
15 Turn 21 - 87
16 Turn 21 - 85
17 Turn 22 - 85
18 Turn 22 - 81
19 Turn 23 - 81
15 I need some info on running this T3 rocket inside on cement, asphalt
surfaces.
If you are going to be running on the street I would go to a heavier oil like
40w front and rear with stiffer springs like Gold front and rear springs. Make
sure that your ride height is re-adjusted so that your front arms are level and
your universals are level in the rear.
16 About the ball bearing set for the steering bell crank. What's the pros and
cons of it.
The pros of the bearing steering is that the bell cranks will work much more
smoothly. The cons of the bearing steering is that it requires a little more
maintenance than the stock bushings.
17 Should replace the bushings (the 2 that the spur sits on) on the spur/slipper
part of the tranny with bearings?
The bushing the spur gear sits on are just fine and all of the Team guys use
them. Bearings will work the same except they will empty your pocketbook a
little more for the same performance.
18 How can I tell when the differential on the T3 is adjusted correctly?
The differential is set properly when you spin one of the tires by hand the
other tire should make one one to two full rotations in the opposite direction
before it stops. If the tires spin freely this means the diff is too loose. If
the diff is too tight your tires will spin in the same direction.
19 Should the foam inserts on tires be trimmed to closer to match the shape of
the tire for off-road cars and trucks?
The best thing to do when trimming your foam inserts is to cut the
inside edge of the foam. This will allow the beads of the tire to fit to the
rim better and the foam will also support the tire much better.
20 When driving my T3 I keep breaking gears in my steering servo.
Make sure that the nut on the servo saver is not too tight. The nut should be just flush with the top of the servo saver hub. If the nut is too
tight it will cause your servo to fail.
21 I just started upgrading my RC10T3 sport. I put bearings and CVDs on it but
now the rear wheels won't fit. They just won't slip onto the pin.
The Associated axles and MIP CVD's have different diameters. We make different
rear wheels for the different diameters. The catalog indicates the wheels which
fit the #6374 stub axles or #7362 universals, and those which fit the #7380 or
#7383 CVD's. (You can drill out your wheels to fit the larger diameter CVD's.)
22 I would like to know if there is anyway that you can change an RC10T3 to an
RC10GT.
There is no way to do so; the parts and mounting are too different.
23 Are the T2 bearings and PTFE coated shock bodies swappable with the T3?
The front shocks can be swapped but not the rear. The rear shocks on the T3 are
slightly longer than the T2 rear shocks.
24 I have an old RC10T. I would like to know if I could use the T3 chassis or
upgrade? If not what about the T2?
The RC10T will not accept the T3 or T2 chassis.
25 How do I clean my truck?
Use a paint brush or what ever brush will fit the area you are working on first
to get the major dirt and grime out of the truck. When you want to really clean
the truck you will need to remove the engine and electronics, then you can clean
the truck with a basic household cleaner like Simple Green, 409, or an
equivalent product. Be careful! These products have water in them so when you
are done cleaning make sure you dry all the steel parts. You can even coat the
steel parts with a light coat of WD40 or help prevent any rusting. Use a motor
cleaning spray to clean your motor and just dust or blow off the electronic
parts in your truck.
26 I was wondering if I could configure my T2 to do wheelies off the start?
To get the truck to do wheelies you will need to get the diff adjustment right
and then tighten up the slipper clutch on the transmission. It will take a
modified motor with the correct gearing and good traction to then get the front
end to lift.
27 I have a T2 and I race on a bumpy dirt track with medium jumps. What setup
should I use?
For a rough track setup with the T2 our starting settings would be:
Front: Silver springs.
#2 piston
35 weight oil
30 deg. Caster
-2 deg. Camber
0 deg. Front toe-in
Rear: Green springs
#1 piston
30 weight oil
3 deg or (optional 4.5 deg.) rear toe-in per side
0 deg. Anti squat
Hub Carrier spacer in front
28 What will a rear sway bar do for my T3?
The results will be less body roll on the back of the truck and increased
steering when installing a rear anti-roll bar. The sway bars keep the truck from
having excessive chassis roll on high traction tracks.
29 Which way should you go on shock oil to get rid of push in tight corners?
To get rid of push in your truck try going to a little lighter shock oil in the
front.
30 I used your T3 setup, but my car bottoms out very easily on the jumps and I'm
looking for a little bit better jumping (farther).
Try going to a smaller hole piston like a #3 pistons front and rear. Use 30wt in
front and 25 in rear. You also should go to a stiffer spring front and rear as
well. Silver front and blue rear.
31 The MIP CVD's do not sit very far into the diff outdrive. They sit there
loose.
Add another shim to space the CVD further into the outdrive. This will push the
CVD into the outdrive, help the outdrive not to chip.
32 If I have a smaller spur and a bigger pinion, will my truck be faster or
slower?
A smaller spur gear and larger pinion will increase the top speed of your truck.
The fewer teeth on a pinion gear means more acceleration and less top speed.
33 I'm having a problem with my T3 motor plate not being able to accept proper
gearing with a stock motor.
The motor plate screws stick into the motor adjustment area and prevent the
motor from moving all the way back. Drivers will either install washers to pull
the screws back or grind the ends of the screws off on the inside.
This along with using the correct set of mounting holes on the motor can will
allow the use of up to a 23 tooth pinion gear with the stock 87 spur. I have
tested this myself in house.
You can also grind or file the top of the motor adjusting holes slightly. This
will allow the motor to rotate more and will allow a 24 tooth pinion gear to fit
with the stock 87. This I have again tested. When you do this you have to use
washers on the motor mounting screws.
By using an 84 or 85 tooth spur gear you can go up to a 22 tooth pinion (if
needed). This will give you the following ratios:
87/20 x 2.4=10.44 at the axle
90/19 x 2.4=11.39
85/19 x 2.4=10.73
84/19 x 2.4=10.61
85/20 x 2.4=10.20
84/20 x 2.4=10.08
The B3/T3 transmission was designed to accept mod or stock motors and to make
spur gear changes easy. Don't worry so much about how big your spur gear is,
just pay attention to your ratio as shown above.
As you have found, the gearing in the back of the earlier manuals for stock and
kit motors is wrong. The correct gearing is 87/20 for both.
