The Novak Smart-Stop 2S Li-Po Cut-Off Module (Novak #5470) is not compatible with the blue-cased Traxxas XL-5 ESC (Traxxas #3018X) that is included with the Traxxas Slash 1/10 2WD Short Course Racing Truck (Traxxas #5805). This module is currently compatible with the original, gold-cased Traxxas XL-5 ESC (Traxxas #3018). Novak is researching this issue to determine if an update can be made to the module or if a separate module can be offered for this application.

Do not use stock gearing with any HV System!

For the New Traxxas E-Maxx (16.8v), Novak recommends a stock spur gear and 12-tooth pinion gear for the HV4.5, HV 5.5, HV 6.5 and HV4.5 High-Voltage Brushless Systems.

This gearing is a safe starting point and should work well with most battery pack configurations. The motor temperature at the end of each run should be checked to determine if this gearing is correct for your setup. It's important to try to keep the motor temperature below 160F.

After extensive testing, we've found that the high power output of the HV High-Voltage Brushless Systems can be too much for some of the stock E-Maxx components depending on how the truck is driven. We used the following performance upgrades for more aggressive driving or racing conditions, and recommend them to anyone who is running an HV System in an E-Maxx. (Note: Not all of the upgrades are 'required', but in the long run, we've found that it makes for a more enjoyable truck).

IMPORTANT: Do Not Use the Stock Traxxas E-Maxx Gearing or the gearing listed in the HV-Maxx's HV Motor Wiring Sheet with the HV-Maxx ESC & HV4400 Motor. Using the Traxxas E-Maxx's stock gearing or the gearing listed in the HV-Maxx's HV Motor Wiring Sheet will overload the HV4400 Motor and will cause damage.

Please read the following instruction update addendum for the newest official information concerning HV-Maxx gearing. This addendum updates and supercedes the gearing information in the instruction sheet that is included with the HV-Maxx system:

PROPER BATTERY PACK ORIENTATION IN SMART TRAY is very important to avoid overheating and damaging batteries. Please note that the battery bar locations are marked on the PC Board for reference--the battery pack should have 3 bars on the top & 2 bars on the bottom when the pack is inserted properly.

Pay close attention to the "Positive (+)" & "NEGATIVE (-)" markings on the Smart Tray's PC Board--these indicate the plus & minus ends of the battery pack where you solder the ESC's RED(+) & BLACK (-) power wires.

The use of CA glues (Cyanoacrylate) on or near your Novak Speed Controllers or Receivers can cause damage and subsequent premature failure of internal components. The glue itself, and the vapors given off by the glue, can make their way into the ESC or Receiver causing corrosion of the circuit board and components. Damage to a Novak product which is caused by the use of Cyanoacrylate glue (or any other glue) is not warrantable.
