I am double-posting this in here and in the miscellaneous forum, but doing so because the 3DR guys are good to get back to me with helpful information. I’m building a hex with a second Pixhawk (yes, repeat customer) and all of the 3DR components (Radios, PPM Encoder, Power Module). It should arrive Wednesday.
I know prop-wash near the body of the craft (or anything else stationary) creates control/stability issues. But is it important for in-plane props to be as far away as feasibly possible?
In my design, at one arm length I can provide 2+ inches between the props. At the other arm length I can provide around 1/2 of an inch between the props.
The wingspan of the device is irrelevant to me. Overall size doesn’t matter. Which arm length would you guys recommend to maximize stability and agility?
