I want to stick a pixracer in one of my tailsitters some questions, mount in horizontal like fixed wing?,a/speed needed,q enable 2,frame class,frame type,flight modes needed,any thing else you can think of? Thanks Rick"
I must admit I haven't actually thought much about the efficiency of the different control methods before but I'd imagine that thrust vectoring using the tilt servos is actually more efficient than modulating thrust from a static…"
"@JB - Thanks for the reply - interesting stuff. So my reason for asking the question is a thought experiment on the minimum system configuration required for a slow speed inspection drone. It looks like the servo controlled motors are able to…"
No problems. We've been pondering these challenges for a while, and most of our experience is from optimizing quadplane performance, which are subject to the same dynamics.
If I may intrude on the question. The wing allows for…"
"@Rick - Let me ask a really dumb question here: Why bother with the wing? Isn't this actually a two motor multi-copter, at least in the way that it's being flown in the video? I know for longer range operation you can make use of the lift…"
In my opinion the propulsion weight is not as important a factor as getting the right prop size and pitch for efficient forward thrust. We get 1.7kg of thrust from 35g motors. and around 1kg from 18g motors, so there's plenty of…"
"Looks interesting and something similar we've been working on for a few years. It's just missing an extra hover lift prop and then you can optimise the forward motors for forward flight, speed and range, because they are no longer…"
