Introducing our Dr. Mad Thrust high performanceseries. The Dr. has been hard at work to bring you MAD power systems with excellent quality and high performance at a price that will leave some cash in your pocket.
The Dr. Mad Thrust series are pre-assembled and dynamically balanced making them easy to fit, with no unit assembly required. As well as high power, these fans have excellent cooling and run so smoothly, the sound is amazing. There is also no housing distortion unlike plastic fans. This high quality, powerful fan is a great way to turn your 40mm jet into a speeding missile!
This 40mm, 8-blade combo with the inrunner motor was developed by Dr. Bret Becker, for his record breaking Electrolyte Micro EDF sport jet, and is capable of pushing the model past the 100mph barrier. That ARF model will be available soon from HobbyKing, but you can get his prescription for power early for all your micro EDF projects!

Works very well as a replacement in my kyosho df45 Mirage(445g flight weight) Fit perfect in the old edf units thrust tube, puts out slightly better thrust and is much quieter. It has a nice sound, a slight high pitched winey sound but more jet "whoosh" sound overall.
Came assembled with a long inlet tube and a short contoured inlet was in the box, which I used.I have two of this on a deltawing bought here. Nice sound and flying time is 13 minutes with 2200 mah, 3 cell battery.Well, credit to HK - They actually seem to have quoted some real world figures on this one - The specs actually tally up very well to real measurements - My figures on the test bench were as follows:
Static thrust 398g (installed in a test stand - no restrictions)
Time will tell if the motor is up to the task - it seems very small to be handling this kind of power. - It gets pretty warm after a couple of full power squirts.
