There at Daves Store is 61-85 the biggest. (61 mm diameter)
It has 1,39 pitch
You can find at Ianboats.co.uk bigger FSR props
I think just you could make a 3 blade prop from ABC 2314 Chopper.
Thank you so much for the advice!!I have data from German competitor Adam C. Used prop MOCOM 2735 (old designation).
I think just you have the possibility to write to TJ Models how to get left rot FSR prop from 7075 Alu or you have to search to any Octura pair and prop tuning specialist.
