I want to put a governor in my soon to be Raven 50, what should I get, a TJ Pro or a Revlock.

Thanks

I have two TJs and love them. Very consistent runs and stable rpm.

I didn't particularly like the Revlock, although I never flew one, for four reasons:

1- The connector pins stick out vertically, what makes it difficult to wrap the unit in foam. They also got bent on a crash a friend had yesterday.
2- Every time you turn on your receiver on you need to reset the governor by passing the magnet under the sensor, what to me is a pain in the neck.
3- You need to mount the governor where it is visible so you can program the rpm you want. This puts the governor always in a crash damaging spot.
4- The sensor reads both poles of a magnet, so you can't balance the fan but putting two sensors, each one a different pole up.

Other than that I am sure the Revlock works great, and it also has the advantage of having a built-in tach.

It's easy to find an excuse to do wrong. Hard is not to find an excuse to do right.

Ok, thanks man, I think I will go with the throttle jockey then, I also like the support Model avonics offers on their website on setup. I guess when we talked about painting canopys, I no longer need to do that now, since I got a Raven 50 that already has a painted canopy. Will you be at the heli event this year in victoria, check out my gallery to see the new bird.

Thanks

The bird looks awesome! Congrats!

You will need a tach in order to set the TJ. If neither you nor any of your buddies has one, then I would suggest going with the Revlock.

Yes, I plan to be at the Victoria fun-fly this year. How about you? Will you be at Mission?

On how I do my break-in (I am NOT an expert...):
- make sure the needles are set on the rich side. The backplate should be worm (a little over your finger's temperature) after hovering. You should also hear a distinct "rich" sound coming from the engine. What you want to avoid is the engine going lean or gurgling fuel. When hovering, the idle needle is more important than the main needle.
- Hover for two full tanks.
- Set the main needle on the rich side and try climb outs to make sure the engine will not bog. Reset the idle needle to match the main setting.
- Next two tanks on smooth forward flight, doing a sporadic loop . The idea is to load the engine and quickly unload it. Keep an eye on the backplate...
If you know how to do autos, do a climb out at full throttle for 4 or 5 seconds and then hit hold. The engine should idle immediately. If it takes 3 or four seconds the main needle is lean.
- Next 6 tanks on forward flight, loading and unloading the engine more often and progressively more intensively.
- Next flights: slowly lean the engine a couple clicks at the beginning of each flight.

I hope it works for you.

Jack

No I wont be able to make it to Vancouver this year, I should be able to make it to the victoria one. I hope the break in goes well, no I cant do autos yet, I can do them on the sim most of time. I ve never broken in a Heli engine before so some of what you said went over my head a little, like matching needle settings. Niether of the few guys I fly with have a tach. How does the revlock tack work.

I got a revlok to try.
Already had one throttle Jockey pro which was great.
but we like to play with new things.

Revlok gives same response for me. no better no worse.

The think I like is the lights system to set it up. You are given this chart. You decide the engine speed you want (based on the gear ratio and required head speed), then simply set that on the bench and go fly.

So I had no need to do the online calculator which for me has not been totally acurate. I have a tacho to get a better result so that was no a problem however.

And the other nice thing is that the revlok is like the gv1. So it takes the throttle up from a lower point rather than my tj pro which you have to get the revs up yourself.

I shall not remove the tjpro as it works fine, but if I bought another govenor, I would get another revlok. It has the edge on specifaction and price..

both are good. personal choice and local favorites can make the choice easier..

Ian.

with the throttle jockey you need a tach to calibrate it! that makes a big difference to me. as for crashes the revloc 10 has almost no mass its not going anywhere a few zip ties and 3 two inch exstensions make a nice break-away to prevent pulling on the pins. its easy as hell to program and is very accurate no tach needed (allthough i did check it the first time) to calibrate. when you must pass the magnet 6 times to get er to boot up might be a lil bit of a pain but it takes about ten 15 sec. by hand (or about 1 sec when you start it). but yes it reads both poles and the counterweight sold for it costs an extra $6 at my lhs. my stock evo fans only have 1 hole for magnet so it made no difference to me.

As scoredpiston said there are a set of LEDs than allow you to set the desired rpm.

Now, going against scoredpiston, I think it is actually an advantage that the TJ needs proper backup curves to operate from.

nogodznomasterz,

you should have made the second hole yourself...

If you had the LEDs, why use the tach to calibrate it?

Hi.

couple of things to mention I think.

the first is to mention about the coment made about passing the magnet past the sensor on the revlok. this is true.
I thought initially this was a problem for me, in that on the bench when I try to set it up, i had to get a starter and battery out to turn it over.
On my machine I could not turn it over by hand.

But I then studied the instructions after a brief from a friend
Did you know that when you turn it all on, if you want to set it up all you do is tap the button and it steps over the sensor test?
So you just turn on, tap the button and do the setup.

You do have to turn it off and back on before flying. And of couse, once set up, when you start the heli to try and fly it, then the sensor test is done.

the other thing to mention is that

Revlok apparently uses the curve to maximise or help responce. Not that I could tell, but it (in my opinion) is always best to set the engine and curves up so it flys in 3d and normal styles without any unit what so ever. then once set pretty well, turn the unit on.

But for sure, if you can not be bothered to get the curves right, then you do not have to. Just as long as the bottom throttle does not drop to low or the revlok will cut off as all others do i think.

I found the one magnet idea pretty good too. becuase when I fitted the TJPRO I had to power up the unit then offer the magnet to the sensor. Because if you get it the wrong way round then it will not work.

revlok works with one magnet either way. so slap it in and thats it. No turning on to try.

As I put, and due to the additionals above, I would have to buy the better revlok if I had a choice, having got both and still using both..

ian.

Thanks everyone for their detailed responses, I have made up my mind and I am going to go with the Revlock.

Thanks again

I reckon you will find that choice great..

one thing I was reluctant to do was this
when you get it, I might suggest you first of all, turn that tiny pot on the board down.. to minimum.

This is a pot they put on there to get the performance right to the possible max before hunting. I reckon they were a bit keen and some cases, pilots have had a slight hunting.

I did and had to tweak my engine setting to a better run.

if you turn that pot to min then it is wonderful. Like the response is claimed to be faster than Tjpro when that pot is turned right down.

So what i did was turn it right down and go fly. Really good. but then I would edge it up a bit at a time, maybe over some weeks. no rush. I found at about 1/4 up it would start to change tone slightly up and down.. So backed it off.
But for me, I would go min and go enjoy.

If not, if you get a slight hunting, turn it down then..

and of course if you do not get any, you can turn it up and up. I know a few who have had that pot to max.. Rare that is.. they must be engine setting dudes.

Well I got a governor, but I did not buy the revlock or the Throttle Jockey Pro, I found a GV-1 new in the box for a good deal so I bought that.
Any setup tips for this one??

Thanks
