hiya, i just got a few questions..

im tempted to get that nice looking GV-1, but im not sure exactly what im buying here.. yea i know what it does etc just a few minor details im not sure about.
1st: how easy is it to set up a GV1 on your heli,
2nd: how many extra channels does it require (apart from the throttle)
- i have a 8 channel reciever, channels 1-6 used on servo's+ gyro sense, and channel 8 for power leaving only channel 7 free

3rd: is a governer a good or bad idea for someone just trying out their heli? I am kind of hoping, that i can get it so in normal mode it goes from standstill to 1600 RPM depending on stick, and then IDLE1 = 1600, IDLE2 - 1800 ?

Is that possible or something similar? olbviously not using exact figures but jsut as a guideline

meh

1. Its pretty easy, reading the manual a few times should help alot, also if you´re getting stuck in someway you always post a question here or ask someone you flyes with.

2. You can use a GV1 without any extra channel free, but that will only give one availble rpm, but if you got another channel free you can change the rpm. Using the StSw function makes the GV turn on and off above 20% throttle curve.

3. I would say its useful, using a GV (or equal) will allow you to concentrate on learning to fly, and not tweaking curves.

Here you can read the GV1 manual.

gv1 is pretty much plug and play

All the settings are done via its interface (headspeed, gear ratio, throttle limits , ect).

You need to have 2 free channels if you want to control the rpm remotely. (You can setup the gv1 so you dont need the remote rpm adjustment and just run one headspeed.). You need to a y harness to free up your 8th channel instead of plugging your battery into channel 8 and use channel 7 to control gov function on/off (or visa versa) Setup this way you can have 3 diff headspeeds in each of your flight modes (normal, idle 1 and idle 2)

The manual can scare you off but it is very easy to program. The tj pro works better (in my opinion) but you dont have the interface the gv1 does and requires a bit more working knowledge.

If your learning it would be to your advantage to learn how to setup a proper curve (throttle curve) but that being said a governor sure makes life easy

"If your learning it would be to your advantage to learn how to setup a proper curve (throttle curve) but that being said a governor sure makes life easy."

Read those words. Learn the basic and then by all means get a GV-1. Though some governors that have come along recently may respond quicker in some applications than the GV-1, the GV-1 still sets the gold standard for flexibility, ease of set up, and tolerance for less then optimum engine tuning.

Answers :
1st : Simple
2nd:1
3rd: If you know what you're doing and why you are doing it , and your engine is tuned correctly , then there is no reason not to use a governor . There is no reason why the settings you propose can't be realised .

At the end of the day , it gets dark .

hey, thanks for all the feedback.

Ok, so let me get this right, all together the governer would use 3 channels

- throttle
- governer on/off
-governer speed control

?? right?

and im guessing in effect, i can start up in normal mode, no governer on, and get just below midstick so that pitch is about -2? just enough to stop it taking off on me, and turn the governer on to start the engine up.

Also, this is fine whilst the engine is being run in right? as long as i keep the engine on the rich side? just means throttle will be slighty more open to get the same effect?

my flight will happen on sunday as long as the weather is nice, so other people may very well be around to help me out, i was planning on giving it a go again myself (but in a very detailed setup instead of my old "assemble and try" check) but i found out i got the day off so help may very well be available

No you dont need 3 channels, the GV-1 plugs into the throttle channel, then your throttle servo plugs into the GV-1, then you need one more channel for remote switching, this is what I do, I use ch7 and use the 3pos switch, bottom pos is off, middle pos is rpm value 1, top position is rpm value 2, this way I can run 2 headspeeds. Or you can use you idle switch to change rpm, you could have normal mode is GV-1 off, idle 1 is a certain rpm vlaue and idle 2 is another rpm value, provided you have assingable switches.

Oh, you shouldn't really break in your engine with the gov on, it can cause a hunting headspeed. You should still set up back up curves that will fly the heli, do your breakin on the curves then go to the governor.

by the way im looking on midland heli's for a Y harness, i can only find a JR one, but i have Futaba hardware on it.

Is JR compatible with it?

thing that worries me is having a overspeeding heli, not knowing about it and then having the blades go woosh at me. OK, if anyone else is at the field i might be better without it.

Wedge from what you have said could i do the following

use the same swtich for the normal/IDLE for my govnerner aswell (i got 9CP) and then have it deactivated in normal, and active in idle modes?

Hmm i have already got channel 7 free, why did someone mention a Y harness, am i missing something?

whilst i got a topic, maybe i should ask if this failsafe is a good idea too

Just thinking in the sense off i dont know how long my batteries last in flight on the heli, im guessing that if they ran too low, signal would be lost and the failsafe kicks in?

Sure, but you have to trim off the tab on the Futaba connectors.

its a jr connector (y harness)

So you dont need to shave anything just plug it in.

Overspeeding is something you should be more concerned about using a 50 engine or 90 engine.

I gave you advice according to the setup you desired. To properly use the gv1 like you initially requested. Wedge is choosing to use his single channel to control rpm. He doesnt have a switch to turn off/on his gv1. You said you are pluggin your battery into your channel 8. Using a y harness is the only way to reclaim that channel (your batter can acutally be plugged into any channel its just using the ground and power pins so a y harness is just freeing up your 8th channel and splitting it so you can provide power to the system.

No harm in the way wedge is setting up his stuff i just prefer to have a master on/off switch. If it works for you go for it....setup is mostly all about preference anyways (as long as its setup correctly)

If you intend to do Autos with the GV-1, you need to use the Stick Switch function, as said earlier. You do NOT need to use up a channel for ON/OFF, unless you intend to run three headspeeds. The Ch 7, 3 pos switch can act as an on/off and set two speeds. The stick switch is another on/off switch. Hitting throttle hold, when setup correctly, also acts as an Off switch when using the stick switch feature. That's redundancy right there. Using a dedicated ON/OFF is a waste.

As you might have guessed by now, there's a million ways to use this thing. At its least, this gem can make a 4 channel airplane radio work with a helicopter, and theoretically allow 3D using a single set speed. At it's most, you have a variety of ways to turn the bugger on and off, as well as have up to 3 separate speeds.

Get it and play around with it. When you first turn it on, it may alarm you as it may seem the helicopter is running up on it's own. It's like cruise control on your car...the first time you use it, it just feels a bit weird.

My personal preferenace would be to have norm mode OFF and the 2 IDLE modes ON - thats possible as a guess?

If i spooled up in normal, then set to idle 1 and governer kicks in i can get a feel of what the right speed sounds like. I can then go back to normal mode and change settings to get the desired RPM without the governer in play. (so in norm mode my throttle curve is done manually, but i set it up with the help of the governer)

So, overall how many channels do i need to run it like this:

(on "governer" on my 9CP i would set switch for following to the same switch as i use for my flight mode)
NORM - Governer disabled, RPM set by throttle curve
IDLE1 - Governer enabled, RPM 1600
IDLE2 - Governer enabled, RPM 1800

I want throttle hold to cut engine RPM down and throttle cut to cut engine in ALL (norm, idle1 and idle2)

I understand i need atleast:

1 channel which is throttle (throttle > govener > servo channel)
1 channel for speed setting - will this also act as my on/off switch

is that all i need or do i need 1 more channel for settings?

ErichF sorry if you already explained this, i found your post slighty confusing and too techncial for me lol

**The stick switch is another on/off switch. Hitting throttle hold, when setup correctly**

does this mean i should also have 1 channel for throttle position so that when stick goes below a certain point, the Governer is disabled (thus allowing throttle cuts and holds)

By the way the governer would be dealing with a OS 37 just to let you know

Webbhost -

Have a look at the CSM Revlock - only needs 1 extra channel (and you can have more than one head speed) and it will also act as a failsafe on the throttle if the signal is lost.

Plus it's less than half the price of a GV1!

bazler, would i be able to set it up as i described ld like above? I figured that because i have the money, its better to go for the top notch expensive stuff for the places that are not likely to break in a crash - i.e. electronics and units like washout, which dont tend to get damaged.

I like the look of the GV-1 and it sounds like it can have a hell of a nice variation of programming on it, but if you think i would do well with the CSM Revlock then im open to suggestions.

Basically i feel that for electronics and stuff, i might aswell go for something expensive that will do me well, e.g. servo's. If you spend alot on one, it doesnt fail on you etc.

Also i like the idea of the GV-1 having a digital display, which would help make setting it up a ease

"Harbinger" yes I do have a switch to turn off the GV-1, its the 3 pos switch, as I stated the bottom position is OFF, the second position is RPM #1 the top position is RPM#2. I like it this way cause I can run any rpm value in any flight mode, or I leave the switch in the bottom pos and its turned off, and I can fly just on the curves.

The GV-1 only needs one extra channel to function the way I have it setup, this is CH7

If you want to use the idle switch to set rpm, yes you can do this too. You said you have a 9C, so use ch7 for the GV-1 and assign it to the idle switch, set normal mode to off, idle 1 is RPM #1, idle 2 is RPM #2. Set STSW on, so when you hit hold it will turn the GV-1 off.

Edited out, sorry. I was wrong about the Revlock, its the revlock that the governor, the revmax is the limiter.

Webhost...

As you explained your intent, you are correct.

What I meant to explain was, using the stick switch function, the throttle hold switch also acts as a governor off switch. This happens because the GV is simply looking at the throttle signal. When the signal is less than 20%, the GV shuts off. Therefore, when you flip the Hold switch, the GV shuts off because the throttle signal is reduced to less than 20%. On that same note, you have to use the stick switch function on the GV in order to practice autos, otherwise the GV won't shut off unless you flip the speed switch to off. Personally, I don't like hitting two switches to do an auto.

So, no, you don't need another channel for the Hold or Kill function of your radio.

Erich,

If your contest this year comes to pass, you're going to find that almost every FAI pilot does use a switch to toggle their GV-1. We do it that way so that between maneuvers we can keep the model seated in the circle with the stick more or less all the way down. Also, it is extremely useful for optimum needle setting to be able to turn the GV-1 on and off while in flight. Wayne Mann won't even tune an engine unless he can shut the GV-1 off in flight.

I certainly don't want to hit two switches to auto either. That's why when I had the 9Z I had the AFR (as per my Team Tip) for the switching channel set to shut the GV-1 off when in throttle hold. Of course, you can't do this with limited channels as was described in the original post, but toggle switching does have very real and valid applications depending on the discipline.

Ben,

I can understand that. I can turn off my GV-1 at any time by selecting the lowest position on switch C (off, 1500, 1800). Unless using a third speed, I don't see the need for a dedicated on/off switch. Would it be because guys associate the speed select with the flight mode switch?

It seems the big differences come between those of us using 9Cs and 9Zs.
