What do you think about the 125 mph goal with a K/B 3.5cc Mike?
My experience is that breaking 16,000 rpm static with a 7 pitch will put you there. Doppler did show my winglet version breaking 130 mph in level filght with a 9 x 7 but I want to duplicate that before making any claims. I have not had an opportunity to test many props much under 9" diameter so I am not sure where a lack of thrust will be a problem with speed. So far my speed runs are in level flight and NOT out of a steep dive. I doubt there will be much further testing until the weather warms up some and I know your winters are colder then mine. I must be getting old because I like 60 degrees F or warmer to fly.
