"I also did autotune with 15x5 props on 6S same 400KV 650W motors,no problem...problem with big props and slow rotation is to have proper ESC who can handle that....with 6S 15x5 I used normal Turnigy Plush 40A,no problems..with 4S and 18x5.5,motor…"
"380kv and 14" = autotune no problems. It was pretty far out (over tuned), but it did at least complete the program.
Way I see it - big props need more torque to respond to acceleration requests. If your motor can't deliver that torque,…"
"I don't know about the steadidone but we are also selling similar copters (in X8 config as the quad is not reliable enough...already had one U8 defective...).
from our experience and users feedback:
- actually very stable, smooth to fly…"
"I am playing with two different types of motors and always try to keep it hover at 50% throttle*. So that should not be the problem. Maybe there is some difference between a quad and a hexa? But I observed no differences between high frequency IMU…"
"I too keep seeing reference to issues with large props. In general, there seems to be a view that larger props are less responsive. I have never seen any data to support this. I currently use 16x8 props but I have a set of 17x8 that I have used with…"
"Autotune worked fine with 15'' and 16'' props. I haven't tried it so far using 17'' (I first have to balance the props. There were heavy visible vibrations of the arms but it was pretty stable in loiter anyway).…"
"Heres that comment again. "Large Props no good for APM"... Is that actually true or is it just settings need more carefully configured? Then APM2.6, Pixhawk ?? On another thread Gary mentioned Pixhawk is as powerful…"
"Interesting discussion! I am currently experimenting with 17'' and 18'' props on different hexa setups. While a lighter hexa with 3.5kg AUW and 17'' works fine the 18'' version with 4.5kg AUW is hard to…"
