Anyone willing to help with CSM RevLock 20???

[ferincr]

Hi, I just installed one of those on my R60 but I got confused with the instructions.
Which RPM target should I look for to set the different flight modes????
Thanks,

What confused you?

Your book should have your gear ratio. Multiply the head speed you want by the gear ratio and find that on the chart, then tweak the end points till you get the lights you need in the rpm range you need.

R50 example, I want 17K on my motor because thats the sweet spot for the hyper, it has 8.5 : 1 gears so 17000/8.5=2000 so I set that for my idle up. For normal I want 1650 so I take 1650*8.5= 14025 so I look for 14000 rpm on the chart, set the rpm range and then tweak the end points or governor menu till I get the lights I need for 14000 or whatever is closet.

Well what I'd like to know is if should I get different targets for lets say normal and idl 1 and idl2
I know ny gear ratio is 9.3 : 1 and the sweet spot for the engine is at 16000, so do I want the max everywhere???
And the other question I have it in a three position switch but the gov have two modes A and B (which it doesn't explain the differences between them), are they just different target options???, I saw that on the Tx menu you can adjust from 0% to 100% would 0% means the gov would be OFF????
should I put 0% 50% and 100% on the three different positions on the switch?

Different speeds....I use normal, 1650 and Idle1 2000 rpm on my Raptor. Normal to hover and low stuff, idle 1 99 percent of the time.

In your case I'd run 1750 or so in idle up and whatever makes you feel comfortable in normal, 1600 or so. Might even try 1800 in idle up or set it and try it in idle 2, there people that run just above max power so if you bog the engine you are dragging it into its max power zone.

Mode A and B..... there is no difference between them unless you want to use the PC interface to set one to RPM Limiter mode but lets set that aside for a second.
Get your card out. You will see 5 rpm ranges, 0 through 5. 0 means off, with a 3 position switch that value would be 50 so if you didnt want a governor in normal mode you would set the value for that switch position to 50.

Lets say you want to run your normal at 1500 rpm. Do your math and come up with a motor speed of 13950, refer to the card and see that you can either go 13750 or 14000 so lets go 14000, that means range 2 so during setup you press the set button till the lights show range 2 (OFF OFF ON OFF) then set the end point for that switch position till you see the lights for 14000 (ON ON OFF OFF), if you go below 50 you will be in mode A, if you go above you will be in mode B, either way it doesnt matter. Now if your idle up speed gives you a motor rpm of 16000 flip the switch to idle up, press the set button until it displays Range 3 and adjust the end point the opposite way you did for normal mode, say you went below 50 there you want to to above 50 till you see the lights for 16000 (ON OFF OFF OFF) If you wanted to run idle up 2 with 17000 rpm then select that switch position, you are already in mode B so adjust that so you get (ON ON OFF OFF), you can have more than 2 speeds set up but you can only use two ranges.

A 9c makes this simple work with the governor menu so I can get specific if you have the 7 or 9c

if you didnt want a governor in normal mode you would set the value for that switch position to 50.
Just to confirm, the mode light should be blinking and that means "no gov" is that right??? The manual says that the light blinking is because it's between zones, just want to make sure that is ok to run it like that
I think I'd like to have the option of no gov for engine tuneups and just in case...

I'm using a 9 CHPS
Is it worth it to have it as a limiter and gov?
I thought about the limiter when I was running woodies, but anyway top speed for this engine would be 1935rpm so I would still be below 2000 :dontknow
Anyway I'll try to set the targets now and see where that takes me...

[BarracudaHockey]

Blinking is off.

Limiter-have to try it and see, you can set it to limit whatever engine rpm you want (or head speed) then run 100 straight throttle curve, it works better for ys engines that tend to surge in governor mode.

9c Governor menu makes quick work, 50 is off, below is mode a, above is mode b. (might be the other way around but thats irrelevent) Just make sure to select the mode you want and press SET till you get the range you want, the adjust the job wheel till you get the RPM (offset) you want.

Make sure your engine isnt running rich, the RL's will act up, the motor needs to be properly leaned in (not burning up but no 4 cycle or running it on the rich side)

Ok, here I go again...
I got the targets (14000 for mode A and 16250 for B)
Now I guess these would be the same for all flight modes (nor. idl1 idl2...) isn't it??? Unless I switch it off :?:
The other thing that is kind of confusing for me is once the gov kicks in (let's say at 25% stick) would it go all the way to get the target, so the throttle stick will be controlling basically just the collective no matter how far above 25% is? Or you will see different speeds along the way? :arggg: :arggg:
Sorry may be these are not very smart Qs, if there is some reading material that you know of like Governors for Dummies, I'll appreciate if you can point me to it.
Thanks one more time,

What I do is tie the governor to the flight mode switch. The reason for this is my first flight with a governor I had it on a separate switch and flipped it to 2000 rpm head speed and went inverted and I thought the engine quit ( i still had the flight mode switch in normal) so it actually went to idle, I landed and reprogrammed the radio so the governor uses the idle up switch. My theory is the less switch flipping the better.

In normal it spools up and the governor catches and runs the head up to 1600, where it stays unless you bring the throttle below 25 percent (throttle curve not stick position). The Revlocks use a sort of "soft start" where once it engages it ramps up the rpm slowly, it takes a second or two to come up to speed as opposed to just throwing the throttle servo where it needs to go.

When I flip idle up it ramps up to 2000 rpm (throwing some delay in the throttle servo in the delay screen makes this nice and smooth) where it stays no matter what. You want to make sure you have a V curve setup in any idle up you are going to use, 100,75, 50, 75, 100 and idle to 100 in normal.

Throttle hold should disengage the governor. (test this, throw the switch and the armed light should go out)

I totally agree with the less flipping the better, I didn't know you could do that (tying it to the same switch). I'll do that.

Should I run it on normal and idl1? or would it be better to run normal without the gov and use the gov for idl1 and idl2???
You want to make sure you have a V curve setup in any idle up you are going to use, 100,75, 50, 75, 100 and idle to 100 in normal.
I have my curves more like U shape than a V
Normal: 9 33 56 78 100
IDL1: 100 60 40 60 100
IDL2: 100 65 56 65 100
Should I make them straight Vs???

That's correct.

[BarracudaHockey]

Should you run it in normal? Some do some dont, I do but its up to you, try it and see if you like it. Even though there are only 2 modes, a and b, you can set multiple speeds within a range(mode) so if your idle up 1 and idle up 2 speeds both fall into the same range just set the second one by flipping the switch and adjusting that switch position in your gov menu to the offset you want. Some people mistakenly think the RL limits you to two speeds, thats incorrect, its two ranges. You could have as many speeds within a range as you have switch positions to call them up.

Throttle curves need to be close, yours are, the RL determines the difference between what is being transmitted (your throttle curve) and what it needs (via the sensor) and adjusts for the difference, the closer your throttle curves are the less work it has to do (if that makes sense).

WOOO HOOO :!:
I finally got it.:banana :happyd :woohoo
I was just a matter for one of my two brain cells to die :Chair (which it happened thanks to this setup :arggg: ) since they were both pulling in opposite directions.
Once they stopped fighting in there I managed to set up Mode A for hovering in 14000rpm (1500 on the head) idl1/modeB with 16250 (to be in the power band of the engine) idl2/modeB at 17000 (just to explore and see what happens).
It took my a while to realize that you have to play with the end point and the governor menus simoultaneously to get the three different targets :thinking
Barracuda rocks!!! :Band :thumbsup2:
I promise I'll give everybody (especially Cuda) some rest now since I'll be out of civilization for few weeks.
Thanks again,

[BarracudaHockey]

LOL no problem.
