Fantom Helix RS 17.5 Turn Upgraded FULL MONTY Dyno Tuned Brushless Motor

SKU: Helix 17.5 Categories: ,


“Full Monty” is British slang for “the works”.  Its what I do to most all motors I tune. In other words, this motor has all options on it available to me. By using aluminum end bell screws, I am eliminating magnetic drag and interference that is caused by normal magnetic metals. Then I take it a step further and install ceramic bearings lubricated with SHAG Oil for even less drag. All these upgrades help unleash each motor’s true potential. The result is a motor that operates more freely and has improved efficiency. Also saves about 2g of weight. This is for a racer wanting the best possible edge.

This motor is professionally built and tuned to Rotor Ron’s strict parameters. What does that mean you ask? It includes the rotor properly shimmed, complete evaluation of stator poles, rotor strength & asymmetry and sensor board deviation. This motor has an aligned sensor board that is within my personal strict standards. Bottom line, you will get an awesome motor! Includes Rotor Ron Dyno Service and instructions that will get you up to speed, fast! Sensor wire, motor specs and dyno sheet included along with stickers for your vehicle.

GREATNESS IS A TOUGH ACT TO FOLLOW, but we did it with our ALL NEW HELIX RS pro racing motors!  The ICON v2 motors are still great motors, but as a racing company, we never rest trying to perfect the performance of our products.  Today is a great day for us as we introduce the best motor we have ever designed in our 40+ year history!
