Hi friends,
I wonder what prop gives you best results for your 40cc... If possible, post your tach readings, static thrust etc. I've been told to move between 20-22" big props, preferably the smaller ones, with low pitch.
My engine will power a big scale RC hovercraft, so I guess I want traction rather than speed.
Another question is the number of blades. If I use a 3-bladed or even 4-bladed prop, what size? What things should improve/get worse? (I've been told they're a bit smaller and quieter)
Thanks folks!
