Please note the following precautions before running  

your 1/10 HIGHroller.

• 

The Electronics in this vehicle are not waterproof and you 

must avoid running the vehicle in or through standing 

water, wet grass, mud or snow.

• 

This vehicle is quick:  

o  Do not run the vehicle if it will be out of sight for any 

amount of time.

o  Do not drive your vehicle near a crowd of people.

• 

Perform a check of the vehicle before going out to run it.

o  Ensure the tires are not coming off the rims.

o   Generally check the vehicle for items such as a 

loose wheel nut, or anything loose on the steering 

assembly. The vibrations of running off-road tend to 

loosen screws and nuts.

• 

Be careful driving when the battery is nearly discharged or 

the car is running slowly. You could lose enough power for 

the receiver to shutdown and you may lose control.

• 

When driving the 1/10 HIGHroller be cautious and use 

common sense.

• 

If your vehicle gets caught or stuck do not pull the throttle 

in either forward or reverse. This will overload the ESC 

and/or motor resulting in damage to one or possibly both 

and is not covered by your warranty.

• 

After running a battery pack, allow the electronics several 

minutes to cool, before running the next battery pack.

Run time consideration for the 1/10 HIGHroller vehicle.

The single largest factor in run time is the capacity mAh of 

your battery pack. The larger the mAh rating the more run time 

you will experience. On the same note, the longer you run, the 

hotter the battery plugs can get. Please check the standard 

plugs periodically. 
For example: if you have a 4600mAh battery pack you can 

expect close to twice the run time of a 2000mAh battery pack.
The condition of a battery pack is also an important factor in 

both run time and speed. As batteries see more use they will 

degrade in performance and capacity.

Driving the 1/10 HIGHroller

How you drive your 1/10 HIGHroller will also affect your run 

times. If you are performing runs, going from a standstill to full 

speed repeatedly, you are asking a lot from your batteries and 

electronics. Hard acceleration draws a lot of current from any 

battery and will lead to shortened run time.
If the bearings are dirty they will cause significant drag causing 

reduced run times and speed.
To improve run times consider the following:

• 

Keep your vehicle clean and maintained.

• 

Allow more airflow to the heat sink of the MSC 12RB ESC.

• 

Change the gearing to a lower ratio, this will make the 

electronics run cooler. This can be accomplished by using 

a smaller pinion gear than those originally supplied. (The 

1/10 HIGHroller comes with a 12-tooth pinion and an 

90-tooth spur gear.)

• 

Change to battery packs of higher mAh rating.

• 

Is the charger you’re using the best at charging your 

batteries? Check with your local hobby dealer.
