The "CAT 4" Fan

The ideal fan for jets with AUW of 25 to 30 lbs AUW

This "CAT 4" or Category 4, fan is designed for sport jets that can be built with an AUW of 25 to 30 lbs. Built using TP-5860 series motors, this fan is capable of powering aircraft that require 20-30 lb thrust turbines on 18s. 

This fan is only sold as a Plug&Play unit with a matched 18s ESC. Each fan is custom built to order, balanced, and tested before shipping. This fan system can be purchased with or without my custom exhaust duct. However, performance as shown in the videos can only be guaranteed if correct ducting is used.
