A couple posts ago I mentioned that I had asked Foxtech whether these props were restricted to Slo-Fly applicatios and whether it was possible to get just the CW rotation versions. What follows is their response:
"dear Dennis,
the propellers are mainly for multirotors, so we sell them in pairs,
sorry we don't sell them in cw and CCW alone.
they are not only for slow flyers, 1150, 1245, 1340, are all rigid propellers for high speed motors,
but yes, they may not as rigid as some APC propellers for high speed motors."
