The "CAT 8" Fan (35lbs Thrust)
Designed for jets weighing 25-35lbs AUW
The "CAT 8" fan is designed for RC jets that can be built with an all up weight (AUW) between 30-35lbs pounds. Built using the TP-5690 series motors, this fan is more than capable of powering mid-sized turbine jets such as the Boomerang Sprint, Hot Spot, and CARF Rookie to name a few. Recommended battery voltage for this fan is either 20s or 22s. See below for performance specs.
This fan should be used with a 22s-24s ESC that is capable of at least 400amps. There are several manufacturers for such ESC's. My personal preference is to use the Fliermodel 22s/400amp ESC pictured below. I have found this ESC to be very reliable, efficient, and cool running both on the bench and in the air.
Each fan is custom built to order, balanced, and tested before shipping. Please scroll down to see test videos of each setup and to determine which may be best for your project. Performance as shown in the videos was achieved using a 12" long exhaust duct with an exit diameter of approximately 4 inches. Using a longer exhaust duct or one with a different exit diameter will have an effect on performance.
