This was posted on Curtis's fb, that definately looks like a 3dr gps.
Vince, I've never tried it! Hope I never have to find out! :)
I'm sure it'll happen eventually though. I would like to get it to the point where the APM could at least recognize the event, and establish a controlled high speed descent so that at least we can have a controlled crash, instead of a blade-stop plummet. I'm sure with enough work, eventually we could get to the point of having a true auto-auto-rotation.
Im having doubts about being able to 'auto' 4 independent rotors. It would be quite a juggling act to keep the right pitch and maintain some maneuverability especially on those light blades.
Rob, slightly of topic, How does the APM heli cope with autos in various modes? Im guessing you have to take over PDQ.
One-ways on each hub would definitely make it auto-better. Fact is belt drag is going to kill it.
I just finished building a Protos 500 heli, which uses a single serpentine belt to drive both the main shaft and the tail. The one-way is actually on the motor shaft, so the main blades have to turn the entire belt drive. When you shut off motor power, the head stops almost immediately there's so much drag.
Belts can be very efficient, provided they don't have to flex back and forth too much. Every time you make them flex, that takes energy, as you do work on the rubber. A standard 2-pulley system has 4 flex points. The Protos has 16.
How many does the Stingray have?
Its certainly the way to go if you are determined to put a gas engine on a quad but I cant see any advantage over a conventional heli. It would be possible to put freehubs under each rotor to greatly improve autorotation.
I think it would all work better on a larger machine.
Maybe it's easier to design a tricopter.
There are some advantages:
- Rotationdirection of props doen't matter
- Better Yaw control
The tail may be done with a conus drive like on the bigger T-rex.
This would be nice for using a gasoline engine!
Dan, I don't remember your input on that, what was it?
Pretty cool thing you built there, I figured you must have made something else to drive the sonars. You must be using a polling scheme?
LOL, what are you doing?!
