Governor question.

Governor question.

Forgive my ignorance on the subject & in electronics.
Why a Futaba GY 701 cannot be adapted when all the parameters are already there.
Don't bite my head off.

Luciano, it's a great little device, and should be able to work. I've just not had the luxury of purchasing one, and testing it. What has stopped me is that I have not found a digital servo with slipper clutch. To me, this is important.

Unfortunately, the actuator drive signals are not the same. The GY-701 outputs an RC PDM "position command" signal, the actuators we have to drive directly off a PWM duty cycle signal.

Cheers,

Francois

Hi John .
Is it ok if I come to visit you and Rick around Bensen days ?? You eagle eyed flyer!!!!!.
Regards.
LUCIANO
Ps. I will ring you soon.
Luciano, You are more than welcome here anytime, Look forward to hearing from you. I was going to try to make it there myself this year, But right now its looking like I will be here, to many good things happening here to leave right now.

Parts is parts

Parts is parts

Today I got the actuator and controller in. Disassembled the actuator and started fitting the position of the new CNC machined actuator body to the collective. I have it all lined out and a simple 2D drawing done of what it will look like when done. Sorry the picture sucks but it looks like I need to order some office supplies like ink cartridges. I haven’t had time to 3D the body because I’m still waiting on a couple parts to arrive to finalize its true position.

Thanks Francois.

Some bigger servos with metal gears would be adaptable (probably not a good idea)

Hi Luciano,

The problem with servo's are, they cannot be overpowered when they drive. You want something that can have an adjustable "slip", so that it is just powerful enough to adjust the throttle hands-off, yet will slip if you hold the throttle firmly. You always want your hand on the collective, and if the governor does not play along well, you simply override it with as firmer grip command.

I looked at digital servo's which have no gearing resistance when not powered up. They will be free moving if the governor is not on. Once it kicks in, it will take 100% control of the throttle movement. If trouble comes along, a simple disconnect command can take away the servo power, making the absolutely free turning in an instant. This may work, if during a problem, you like a governor disconnect command, with the pilot taking over.

Cheers,

Francois

Hello Everyone!

I just joined this forum a few minutes ago and this is my first post. I have to say... I love it! Seems like a great group of people.

I currently have a 162F piston ship but plan on building an under-slung turbine (T62T-32) ship very soon. I'm just not a fan of the JetExec conversion kits out there as they seemed to have quite a few issues. Some of which have been updated/corrected but, I'm still not a fan of having the turbine mounted so high. There's a guy that's a few hours away from me that's building an amazing under-slung turbine Rotorway. He's building 2 of them and I'm hoping to buy one of them within the next few weeks.

When I first got into flying helo's I started in a R44 (@ $485/hr! :rolleyes:). After my 8th or 9th hour I purchased my Rotorway because I could I build my time for a fraction of the cost. So far I have zero regrets!

Right after I bought my ship I was hell bent on adding a governor but my instructor begged me not to. He said I would become a much better pilot without it (and he was right). After I was more comfortable he said it would be fine to add a governor.

After doing some research online I found this post. There's a lot of great information/suggestions within this post but I noticed that nobody has posted anything recently. Is anyone able to provide any updates on their governor?

Thanks!
-Sam

Welcome to the forum Sam. The Rotorways have interested me for some time. I hope to hear more here about your machine and flying adventures.

Thanks Todd! Rotorway's can be a lot of fun and they're actually very safe... As long as you keep up with your scheduled maintenance. Unfortunately, there are those who neglect their maintenance and then wind up in trouble which can make all Rotorways look bad. I love mine and look forward to building another soon!

I'm still hoping to hear from someone that has a reliable governor. Anyone? : )

Thanks!

Governor is an automatic adjusting device, which can automatically increase or decrease the fuel supply of the injection pump according to the change of diesel engine load, so that the diesel engine can run at a stable speed. It can be used in various electrical equipment.
