Brushless EDF: Ofna Ultra GTP

[What's_nitro?]

Thanks everyone. Metalman I didn't see that bit about 30K RPM anywhere in the instructions for the fan. Thanks for mentioning it. It is good to know that the Lehner can take the beating without kerploding, but I guess I have to find another fan. I really want to stick with a single fan setup to save the extra weight. I need a MINIMUM 9# of thrust for the project because I'm aiming for at least a 1:1 thrust-to-weight ratio. Also, I want to stay with the 90mm size fan, or smaller if such a thing exists.

Please, no more links to those R/C turbines. I know they're awesome but unless you want to donate one then they are out of the question.
