Adequate static thrust for model?
I'm building a rudder-only 25" WS Fairchild. I've set-up a Cox Pee Wee 020 (extra shims, low nitro% fuel) so that it's turning a Zinger 7X3 at around 4400 RPM's. I estimate that wet weight will be about 5.5 oz.
Will the Zinger provide enough thrust for scale-like flight?
