Plane was hovering nicely but a bit underpowered. I went from 4s to 5s (and changed props from 15” to 13). At first it was shaking terribly so I detuned all pids and shaking stopped. After an afternoon trying to bring them back up a bit, all good except yaw. Very sloppy and when I try to increase yaw values the shake returns. I think the lower torque (but higher rpm) probably accounts for the lower yaw response.
Any suggestions appreciated.
Also I just ordered some 14x5 props which just fit under the power limit.
That’s quite a large aircraft for that low of voltage, isn’t it? 14” props? I’d think that you’d want 6S, at least, to get enough tourque for stable quad movements… I’d be going for 8-12S on a build that large.
That’s a plan. I can easily tilt the rear motors but the front ones are mounted on an adapter which is glued to the tube, however it’s easy enough to print the mount slightly tilted.
The numbers all work in ecalc and even 4s with 15” props was working ok except in turbulence. As long as you match the volts, Kv and prop it should be ok if your ESC can handle the amps except there’s a bit more wire losses with high current.
