Questions
This NDS kit has foam tires. I would like to go to rubber tires
and wheels.
I am racing dirt oval with the NDS and could actually get it to handle better
if there was a way to widen the stance on the car.
I was considering turning it into a RC10GT. What changes do I have to make?
Can I add the slipper clutch to my Qualifier kit?
I don't know how to set up my brake/throttle linkage correctly the first time.
I have converted my NDS over to touring wheels. Here's what I did...
Will MIP CVDs made for the electric Dual Sport fit my Nitro Dual Sport?
I installed a .15 engine on my RC10NDS and it keeps on spinning out on me when
I go full throttle. Is there anyway to stop it from doing that?
Do you need a short crankshaft for the RC10 Nitro DS just like the RC10 GT?
Are you going to come out with a 2 speed transmission for the NDS?
How to get some of the push out of the Nitro DS? I want to get more steering

Will just any super speedway car body fit the rc10NDS?
What .15 engines would fit?
Is it possible to mount a .21 engine on my NDS? Is the gear and differential
going to hold under the pressure?
I am having trouble getting my rear hooked up to the unprepared asphalt.
Answers
1 This NDS kit has foam tires. I would like to go to rubber tires
and wheels.
Front rubber tires #8886
Rear rubber tires #8896
Front rims for rubber tires #8880 chrome, #8881 black
Rear rims for rubber tires #8890 chrome, #8891 black
2 I am racing dirt oval with the NDS and could actually get it to handle better
if there was a way to widen the stance on the car.
You could change it over to the GT arms, but you will have to change the
turnbuckles and CVDs (or dog bones) also. That would give you a much wider
stance.
3 I was considering turning it into a RC10GT. What changes do I have to make?
You will need to change the front and rear a-arms, the shock towers and the
shocks, dogbones or CVDs, and tires, wheels, and turnbuckles.
4 Can I add the slipper clutch to my Qualifier kit?
You can. Part numbers are:
#6583 Torque Hub Inner
#6584 Torque Hub Outer
#6585 Clutch Disc
#6596 Bushing
#6594 Thrust Bearing
#6587 Spring & Nut
6 I don't know how to set up my brake/throttle linkage correctly the first time.
I put this new instruction sheet online in PDF format. Click here and print it
out.
7 I have converted my NDS over to touring wheels. Here's what I did...
I used most of the parts in the link at top, but also changed a few. I used two
hex adapters on each front side, also spaced the rear out to match. I am using
HPI super shocks (sorry) with HPI black springs in front that I cut 2 coils from
and HPI red springs in rear with 2 coils cut from them. I also changed the
mounting points of the camber links to get almost zero change in camber from
ride height to full compression. I also changed the tie rod points on the
spindles to the under side to get rid of the bump steer.
I also relocated the fuel tank as far to the right pass. side as I could and
turned it around. I mounted the rec. next to the fuel tank. I then moved the
battery tray to the pass. Side front kick in and have it hanging over the
steering servo. The front end of these cars is a little too light.
I am also using aluminum front bulkheads as well as the upright carriers, there
is also a chassis brace to keep the gears meshed. I use Pro-Line mounted foams
or the mounted slicks.
Let me tell you that everyone at our local track is in shock at the way this
thing handles. Several drivers have the NDS and cannot believe that it is as
fast as it is. When you can take a 2WD car with an OS CV12 engine and out run just
about every HPI nitro RS4's with the 1HP engine along with the Traxxas 4-Techs,
that is saying something.
I do have the ride heights very low, ( .150-.250 in front and .240-.300 in the
rear ). Thanks for all the fun!
8 Will MIP CVDs made for the electric Dual Sport fit my Nitro Dual Sport?
The CVDs for the DS will fit the Nitro DS.
9 I installed a .15 engine on my RC10NDS and it keeps on spinning out on me when
I go full throttle. Is there anyway to stop it from doing that?
With a .15 engine in it there is too much power. We recommend a .12 engine.
10 Do you need a short crankshaft for the RC10 Nitro DS just like the RC10 GT?
Yes, you do.
11 Are you going to come out with a 2 speed transmission for the NDS?
Unfortunately we have not found a way to install a two speed on any of our
current 1:10 gas powered vehicles. The chassis is in the way for the GT and NDS.
12 How to get some of the push out of the Nitro DS? I want to get more steering
out of it.
If you are looking for more high speed steering, disconnect the front roll bar
and leave the rear on e on. This will allow more weight transfer to the front of
the car, giving it more steering.
13 Will just any super speedway car body fit the rc10NDS?
With the foam tires, most should. Just make sure that the body is 8 inches wide.
I have seen some new super speedway bodies that are now narrower then 8 inches.
14 What .15 engines would fit?
For the O.S. 15 the answer is no. What will fit are the Thunder Tiger, HPI, and
Leo 15. Ofna also has a new .17 that will fit, but in my opinion they will not
go any faster. Engine RPM is the same.
15 Is it possible to mount a .21 engine on my NDS? Is the gear and differential
going to hold under the pressure?
The NDS was designed to fit up to a .15 engine. If you put a .21 size engine in
it, it might not hold up to the power.
16 I am having trouble getting my rear hooked up to the unprepared asphalt.
Try additional rear toe in for the rear hub carriers. This will help accelerate
much better in a straight line.
RC10GT to RC10NDS Conversion
This notice is in response to several requests for converting an RC10GT to an RC10NDS. It is possible to change an RC10GT into an RC10 Nitro DS. The only major difference is the converted GTs wheelbase will be about ¼" longer. This is because the Nitro DS chassis is about the same amount shorter at the front of the chassis. It is feasible to cut the RC10GT chassis down, but it's not recommended for the average hobbyist.
The most economical way to do the conversion will be to start with the #8089 RC10DS electric conversion kit. This kit will give you most of the parts you need, leaving you to purchase only a few parts that are different for the Nitro version of the DS. The following parts are those that are different for the Nitro DS than what are used in the electric DS or GT.
Exhaust manifold #8910 (discontinued). The stock GT manifolds will hit the tires when the wheels are moved closer. (Optional: the #8912 sport muffler can also be used).
Rear bulkhead #7526 (The GT rear bulkhead has been updated with rear anti-roll bar mounts. The old bulkheads can be modified by making rear anti-roll bar mounts.)
Rear shock strut #8873 (this is the stock Nitro DS rear shock strut which is designed to bolt onto the #7526 rear bulkhead).
Spur gear #8916, #8918, #8920 (due to the smaller tire diameter you will need different spur gears. These are the three currently available that we recommend. Sizes are 56, 58 & 60 in the order shown).
Clutch bell #8902 or #8904 (these are the two clutch bells currently available for the Nitro DS. They are 22 tooth and 24 tooth respectively).
Rear anti-roll bar kit #8875 (it may be possible to modify the rear anti-roll bar from the conversion kit but we have not had time to try it).
Front steering block #8814 (While the steering blocks and axles from the GT will
work they make the car to aggressive on the steering. The #8814 steering block
is a trailing axle design which makes the car easier to drive.
Front axle #6219 (the #8814 steering block uses the original RC10 front axle
which is a trailing axle design).
The conversion kit comes with tires but the compound in the conversion do not work well on the Nitro version. We recommend using the #8886 and #8896 "G" compound tires instead. This is the compound included in the Nitro DS kits.
For those who what to make the modified GT to the exact dimensions of the Nitro
DS, the chassis is #8815.
