I have a question about props... I see DD (direct drive), RD (reduction drive), and 'slow flight`·
When (measured in rpm?) should i use the different type of prop?, and how much diffeencedoes it make?
I understand that ther is a safty concern turning a slow flight prop too fast, but I dont know what too fast is.
This may be good for a josh and josh segment where they could try to spin a slowfly prop too fast and see the distruction....
I am not using gear rduction so the rd props dont seem the rigt choice, but I cant choose between the sf and dd props for a funbat, a blue baby trainer, or a f22 raptor...all using the same motor and same size prop 8040 24 gram hextronic 1300 kv
