Default Kress thrust???
I have this fan right now, and I can get about 3.5lb of thrust out of it. I'm using a .21 MVVS with 30% nitro.

Kress claims just under 4lb with a K&B 3.5 at approx 23K RPM (all with 25% nitro).

As far as max RPM's, I hear that Danny Starkey (the master of .21 fans) can get 29K with a top end Nova Rossi .21 engine.

The .21 Rossi's put out more thrust than the K&B 3.5 and the OS .25 VRDF.

What are you putting the fan into? I'm always interested in hearing from other guys flying the .21 fans. Right now, I'm preping a Mirage and an F86 for test flights, with a dual .21 SR 71 on the drawing board.

Email me at [email protected].

Hope this helped. Good luck.
