I am wondering how reasonable it would be to build a twin engine VTOL UAS that uses some sort off 2 dof gimbal/engine mount for ‘drone’-like flight but could convert to standard wing-lifted flight. Right now I am thinking something along the lines of a terminator hunter killer shape but using brushless engines and props. I have seen several that appear to fly like the V-22 osprey and have what are for all intents and purposes rotor rather than standard length props or use 4 tiltable brushless motors. Does anyone know of any current RC aircraft that operate like this, the criteria being the ability to loiter like a quadcopter transition back and forth between this mode and standard wing lift flight?
Is that a trade phrase?
It made me LOL.
And cool questions. I don’t know the answer, but am also interested to find out.
LOL, it should be, multi-rotors are good at it and then they can zip off and do it elsewhere.
Notice I used a fictional aircraft for my example of what I’d like it to look like… because:
Something like this?
LOL, but it has rotors though…
Sounds complicated…
Have you searched the FliteTest site? If anyone has done something like that, I would bet on those guys.
Good point, I’ll give them a look.
LOL I’ve seen it done with EDFs there is an avatar gunship out there.
This is making me want to pull my cobbled-together F450 clone out of the closet and fix some stuff…
I’ve seen many examples of this in Model Aviation and other places.
Here’s one that looks cool: https://www.youtube.com/watch?v=FSc2ZKieNZ8
just search for “rc osprey”
this one doesn’t have gimbals, and it’s 4 blades, but it’s still cool, and it’s human scale… http://www.hover-bike.com/
The tilt rotor osprey is a bucket …
The CH47 Chinook helicopter posted above is a reliable 40 plus year old workhorse and the one of the fastest moving targets in the true rotor wing field(been there, done that, in real life - not from a game console)
Not to be mistaken with the other USMC bucket of …CH46 Phrog
Hmmm it almost looks like the blades on that Walkera are variable pitch (or whatever that is for rotors, variable angle of attack?). Wondering if I could make this work with standard quad props, the biggest thing I can think of that would make it have problems is getting enough pitch authority at low speed. Not sure how to pull that off realistically with fixed pitch props. I think I may be spending some time in X-plane’s plane-maker this weekend.
yup - for sure variable pitch is out there. just search “rc variable pitch propeller”
you can go hobby size:
or “a bit larger”:

My cousin has completed a v-tol wing (its a modified FT Mini arrow with a blunt-nose-versa-like conversion and twin tractor like the kraken) but in v-tol it uses the elevons instead of gimbaling the motors
