Governers...

Is a governer something i should look into for a raptor .30?

I can setup throttle curves, but i do have a tendancy to overspeed when coming down and using negative pitch....

Does the difference justify the cost? Im not really 3ding yet... but will be in that arena soon. Im semi-comfortable inverted and get alot of sim time, so im not to far off....

Should i just wait till i upgrade to a .50 next spring?

I know a number of people who 3D their heli's without the use of a governor and they run great. I myself run the Futaba GV-1 in my heli's. From what you have described it doesn't sound like you would gain much benefit from a governor at this stage. Once you get into flying 3D you will have a better idea of what kind of governor you will need, if you feel you need one.

What I like about the GV-1 is that I can program the head speed to exactly what I want, and it will maintain that speed in all conditions (providing you dont bog down the engine!). Other governors, such as the "RevMax" by Throttle Jockey (I use the word governor loosely) are actually throttle limiters, where you can run a high pitch curve and know you are getting the maximum power out of the engine, but you don't have to worry about overspeeding (They also say there is no lag with the TJ, although I've not noticed one with the GV-1).

Check out these sites for more info:

The RevMax is a great limiter and will definitely help with your over speeding condition. A governor is worth the money and you will notice a big improvement in consist ant head speed.

If you want an extremely versatile and easy to setup governor, check out http://www.aerospire.com/index.html. The MultiGov allows you to set the gov for different head speeds in all three modes and the biggest feature is, you punch in the head speed you want and that's it. No more tachs. You can also use it as a governor or limiter in each flight mode separately.

That thing sounds pretty cool, it's the best of both worlds in one unit (governor and limiter). By the way, you can punch in the head speed on the GV-1 as well in the same way.

Haven't used the GV-1 so I can't comment on how it works. The MultiGov is very nice. Here's how I run mine...

normal - 1650 gov
idle-1 - 1850 gov
idle-2 - 2000 limiter

It has enough features to tweak anything you want.

How do you have your throttle curve set up in idle-2? A friend of mine has the revmax and runs his throttle curve at 100% in idle up.

That's what great about the revmax. Just drop the percentage in you radio to dial in the perfect headspeed.

Or if you use the MultiGov, just select the exact head speed you want and your done. And no need for a tach!

Most people do set their idle-up at a flat 100% when using a limiter. As long as you can switch out of it quickly if you throw a magnet, there's no problem. I actually run my curve at 100-95-90-95-100.

Same witht the GV-1, this is a common feature now. Although I would still like to tach it to check to see if I am getting the actual head speed I programmed.

This brings up the question....

What is a safe headspeed for a Raptor .30 v1? It's stock with reinforced wood blades.....

I don't have an optical tach.... i have a standard tach, but im not going to get close enough to use it.....

You can take your standard tach, put some foam on the back of it and zip tie it vertically to your boom. Switch it on and hover sideways and you can read the output on the tach

The headspeed will depend on the engine, what are you running in there?

TT .36, on 15% now, will go to at least 20% soon.... Im having fuel availability issues with powermaster 20/20 that i usually run in everything....

While there are many that use a RevMax and flat 100% throttle curves and are happy with it, Model Avionics, the manufacturer of the unit says that that is not how it is designed to be used. If you want a governor then buy a governor.
The Rev Max is designed to be used with functional pitch curves and just give that little extra to help prevent over speed in the cases where you can not get the throttle curve just right, like in a power decent.
You will actually get better performance buy using a governor as a governor and a limiter as a limiter.

I am lazy and do not want to spend a month setting up perfect Throttle curves so I buy only Governors. I have both TJ Pro's and GV-1's. The GV-1's are easier to set up and use and the TJ is more accurate. I have not personally used any others so I can not compare them.

A R30V1 still has a 5mm spindle and you say you are running wood blades.
Regardless of blades used, with the 5mm spindle and plastic head block I would not run over 1750.

There are advantages to each type of gov/limiter. I used the GV-1 for years until I started more aggressive flight. That is when I really noticed that it has a lot of lag for throttle input. It has to sense a decay of head speed before it starts to ramp up the throttle. I went back to throttle curves and the lag went away.
I always recommend setting up your machine with curves and when the engine is broken in and everything is tuned appropriately, then activate the governor of your choice. If you are using a rev limiter, you can use that from the start to keep from overspeeding.
The set up that I have ended up being very pleased with is the RevMax and using my standard throttle curve. You can raise the throttle curve about 10 or 15% to insure the engine is operating at the given rpm or run a straight curve (which I don't recommend). You of course will have your normal mode to switch to in case the rev limiter "wiggs out" or if you have a sensor malfunction.
One other feature that I like to use is the remote gain on these so that if your are flying in exceptionally windy conditions you can just bump up the head speed during the flight.

I believe TT recommend the max head speed on stock blades to be 1850. However people run anything up to 2000. The best thing to do is to play around with your curves until you can get it where you are not bogging down the engine when giving it full collective, and it doesn't overspeed when you are reducing collective - its kind of trial and error until you find a setting that works for you.
