I don't have one , the best I can come up with is a 3 axis flight stabilizer from JRX or ORX

After reading a lot on the fpvlabs leaderboard, it became clear that a limiting factor for pushing really high alt is that the air at high altitude is so thin that props have to spin extremely fast to produce enough thrust (the other is the ambient -30°c but thats something else)
so I decided to make a variable pitch prop using folding prop blades, I havent started CAD work yet but theorically a simple ceramic bearing and a few printed parts could do the job. Could also help for planes like the mini talon that are hard to launch but can aquire a good high end pitch, provide lots of static thrust at launch then increase the pitch angle to produce less static thrust but more pitch speed for more efficient cruising.
In short, like real airplanes do.
I will have to work on that, it could be useful.

Sweet idea! Going to put some work in my design tonight.

I am going to put some foam tubes together maybe just with some dowels and see if it will somewhat glide plus find a somewhat balance point. The model itself everything can slide on a 7.6 cf arrow tube I have and I am going to make a battery tray that will also hang from the tube and be adjustable that way. Who knows , the most I am going to waste is time, minimal foam and filament.
The other thing I thought of if this doesn't work I can print off another front section and turn it into a 4 setup , 4 elevons

WOW!!!! That's really cool!! That my kind of heli!!
Where did you get that helicopter??? Is there anywhere I can get a RTF?

Thanks! I built it from a few various kits. Full build thread here: https://forum.flitetest.com/index.php?threads/500-size-uh-1c-huey-174th-ahc.39384/. There is no RTF, closest would be this guy: https://www.motionrc.com/collection...ale-uh-1a-medic-green-450-size-helicopter-pnp.

No problem! Helicopters are definitely a good bit pricier than fixed wing. Unlike airplanes, helicopters require a flight controller, and a lot of specialty machined parts in order to function. If there is any slight imbalance or slop, it can effect the aircraft badly.Thanks for the links!
Helicopter do cost a pretty penny, just as I feared!

Don’t completely count them out. I really recommend that everyone try a heli at some point. Its a totally different type of flying, and lots of fun. I wouldn’t start with a scale heli though, something like the Blade 230S V2 is a great heli trainer. I fly a mix of airplanes and helis, and I can easily say that scale choppers have become my favorite corner of the hobby, despite all the difficulies.Then I guess I'll stick with fixed wing.

I did have a WLtoys V911 heli a few years back. Fixed pitch. I had a lot of fun with it for a couple months until something happened with the gyro, it didn't fly at all after that. Maybe I'll get back in to it when I have more money. I can't afford Helis AND fixed wing right now. Thanks for the info!

Wait like five minutes, I'ma go grab the popcorn...Well I changed my mind and now it will be 4XTrouble
Basic frame work is done, all arms rotate individually .

Your right, it will match your avatar-- It will be one "wildthing". Point to make-most gyros only can be used with servos, not connected to motors. That's why a flight controller is needed.

My thinking is the motors are only going to be for turning using the differential thrust, the servos should be doing the rest.
I did start a thread on this guy also
