Prop research project

[Wagtail]

Good morning, we are at the last stages of a project in which we are measuring and comparing the air flow characteristics coming off different types and makes of props. We are looking for a Left hand WARP drive 4-blade anything from 70 - 74" ( A ROTAX in Pusher config or an Auto engine with belt drive also in Pusher config will have this rotation) to borrow for just one Static run. No flying or take-off. It will literally take about 30 minutes and then we will be finished.

Any help with this one will be much appreciated.
regards
Johan
