This page is for power systems that people have found to work well. I have put in 3 of my favourite ones. If you would like to add some of yours please e-mail me at: mike.sayer@dsl.pipex.com

Graupner Speed 600 Race

This motor works well with an Aerojet style model, that is a 48 inch, 42 oz middle wing aerobatic design. The model flys fast with a fairly good climb rate. This would also work well with something like the Balsa Craft war bird series

Flight Pack 8 x RC2400
Propeller 8x4 slim prop
Flight time 5 minutes of spirited flying
Max Current 30 amps
RPM 10650

Flyware LRK350/25 10.5

This brushless motor works great in my Cougar 2000 and should be OK in any of the standard funflys e.g Limbo Dancer. It will prop hang and accelerate vertically out of the hover. My Cougar weighs 4 lbs, which is very similar to the expected IC weight. Performance is similar to an IC version with less duration.

The motor and 70 amp Hacker controller I used are available from Weston UK.
This is the site for the motor FlyWare which is mainly in German.
The original amateur site which these motors are based on is at LRK

I used this motor in FVK Absolute hotliner. It will climb vertically ,but the fastest climb is probably at about 70 degrees. 5-8 secs will get you as high as you want. The model weighs 60 oz, for info see here FVK Absolute
