Following much speculation about the follow-up motor of the successful D3.5, Trinity now officially introduce the D4 electric brushless motor. Designed to meet all ROAR specifications the motor is based around a new stator design and a 3-piece heatsink can with an updated endbell for improved bearing alignment and increased airflow for lower operating temperatures. Other features include windings made from certified pure copper wire, grade 5 ball bearings, and new larger silver-plated solder tabs. The motor is 8 grams lighter than the previous D3.5 and available as 2.5T to 9.5T modified and 13.5T and 17.5T ROAR Spec stock motors. The motors should hit stores by the time you read this.
