When Xtreme Power Systems set out to find a fan system that could meet our extreme needs, we discovered that the Dynamax fan was the best choice. This fan system was originally powered by a OS.91 glow engine.  We have converted this fan system to electric, using several motor combinations.

Thousands of planes were built and flown on glow ducted fans.  Most of these planes were just simply retired because glow engines were always difficult to keep running in these setups.  Now, these planes can be brought back to life using a fan system that not only provides more power on a 10S setup than the OS.91 could, but also with the added benefit of it sounding like a turbine instead of a "hair dryer".  Breathe new life into that old model!  Choose from two models described below.

Series II motor on the left, original motor on the right.  Series II has a billet shaft, and rubber wire isolators.


The Dynamax Xtreme PRO 2 fan system uses an improved version of the success PRO motor that has proplled many jets to record speeds.  There is no electric ducted fan system more powerful in the world - period.  Until we produce a larger diameter fan, there is nothing more powerful available  (at any price) than this setup!
