Novak Ballistic 550 Brushless "Short Course" Motor (4.5T/5000Kv)
This is the Novak Ballistic 4.5T (5000Kv), 550 Size, Brushless "Short Course" Electric Motor. Novak has repeatedly brought original products and technological advancements to the R/C industry, and, to no one’s surprise, Novak is doing it again! Novak Ballistic 550 Brushless Motors are the first 550-sized motors designed specifically for short course competition and will easily outperform traditional 540-sized motors. The Ballistic 550s are more powerful because of their extra long stator and rotor magnet. In fact, the stator and rotor magnet are twice the length of 540-sized motors, which equals twice the torque when compared to the equivalent 540 motor. More torque, means more speed!
Additionally, these larger-sized motors run cooler and more efficiently than their 540 counterparts. These high-powered motors are the top choice at small, indoor race tracks and easily install into OFNA’s Hyper 10 SC, OFNA’s Jammin’ SCRT 10, and the Traxxas’ Slash 4X4 Short Course Trucks, as well as other 1/10-scale short course trucks. In addition to the low-speed driveability and no cogging, the sensor-based Ballistic 550s have been fitted with rugged 5mm output shafts for maximum resilience and race life while offering smooth and controlled power delivery.
BALLISTIC MEANS VERSATILITY:
Novak Ballistic 550 motors are completely rebuildable and feature interchangeable wound stator construction. A stator swap allows for easier experimentation at the track and cuts down on racing costs. Additionally, all of Novak’s Ballistic 550s feature a replaceable rotor, front end bell, sensor harness, bearings and other replaceable items.

Don't know why Novak is factory setting the static timing on this motor to 30deg advance, because with the gearing in my TEN SCTE 4wd (Mod 1.0 pitch 40t spur & 11-13t pinion) and retarding static timing to 5 deg, the truck still hauls a--. Maybe that's what works with Novak sensored ESC's- don't know because I'm using a MambaMax Pro w/ SmartSense sensorless operation.
Losi recommends ANY 4.5T 550 motor and 16T PINION for this truck- NOTTTTT!!! Ran 2 laps with that setup and the Novak motor was cooking over 195 deg. and the truck speed never topped out on the 100ft straightaway!! Guess the Losi Excelorin ESC (also Losi-recommended) handles that gearing by some kind of current limiting/torque control...don't know.)
With both geared correctly in a Jammin SCRT10 my Castle 5700kv 540 motor hits temps over 160F near the end of a battery pack while my Novak 4.5 550 motor never gets above 110F. This is with a 2s battery.
Do keep in mind the motor is quite a bit heavier then the 540 size so you might need to fiddle with your cars weight balance a bit.)
