Hello to all.

I have some issues using the Align RCE-G600 governor that came in the box of my Trex 600NSP. At the time we speak I have burned 4 gallons of fuel.

After the break-in flight, I started to fly the bird in some FFs, FFFs and some figure8 just to get used to it. From the second gallon, I have triggered the RCE-G600 at 2008RPM headspeed. I saw lot difference and great improvement in heli's behavior. Everything was going better and better cause the fear got away from my hands and I started the first flips.
Now the problem started. Some times as the heli was flipping and its position was going inverted, the motor was loosing speed (like the th.hold was pressed). As everytime I was in a good altitude, I was able to return the heli to the original position (hover). As the heli went out of invert, the motor started gaining speed and reached the desire RPM's.

The thing is that I face this behavior a long time ago and I started doing some tests to find what was causing the problem. Unexpected when I disabled the governor, everything went absolutely fine. I pushed the heli in flips, rolls, loops, tik-toks and I didn't got the problem again. As I activate the governor after a while, the problem came again. I cannot understand why the heli works perfect with the align governor and at 50% of the times going inverted I have this issue.
My throttle curves are 0-20-40-60-80 and 80-67.5-55-67.5-80.

I have freaked out guys cause I cannot understand why this is happening. Any suggestions on this?

Thanks in advise,
George

how did you initially set the govenor up, ie. push button, trim at center, start at low on throttle stick, move it to high and wait for light to go green?

Yep.
I did twice like the manual said.
Set throttle curves 1-25-50-75-100, all trims centered, set a switch so I could activate the gov, powered up TX with thr stick all way down, power up RX, triggered the gov switch, push the throttle travel setting so the led starts blinking, puss thr stick all way up so blinking led stopped blinking.

thats kinda baffling then I agree. the governor is supposed to correct a lot of tuning issues for you, maybe the clunk is coming out of the fuel inverted and the governor is struggling to correct for the lean run? do you use regular clunk line in your tank? Are you running a header tank?

I have replaced the clunk line with a better one and I have checked if the clunk could stuck somewhere inside the tank but everything seems to be ok. I also use a header tank (always full) with the same checks on it. I thought that the problem may be caused by the fuel line and I replace the old tank, disconnect the header tank but nothing better happened.
What you say is a good idea but I think I would have problems even if I disabled the governor. But now when I disable the governor the heli works absolutely fine.
So why the 50% of invert flight the governor acts like that and all other time the heli works perfect?

I had an issue very simular to this when I first setup an RCE on my 700. I am having a hard time remembering why it did it. I know I had something setup backwards. The gov was actually turning off at a certain point. I almost think that when I first set it up. I bound the Rx, and setup the gov. then when I went to install the throttle linkage, I realized I had to reverse the throw on the throttle channel. never thinking to redo the gov. It would still work, but was cutting out. Not sure if it the same situation, but thought I would mention it.

OOOOOOOOOOOOOOO.
Man you saw me an idea. I am not sure if I understood perfectly what you metioned (my English are not quite good, sorry) but I thought something about what you mentioned for reversing.
I don't think if this is correct but align says to have our thr curves over 50% (100-50-100 lets say). I put mine to 100-55-100 just to be sure. Is it possible (if the ch7 wants to be reversed) the governor to read 100-45-100 ? ? ? ? ? ? ? ? ?.
If this is possible, it is almost certain that you are correct and the governor is truly turning off. Ohhh God, it seems perfect answer to me.

Please advise

George

I have to give this some thought. give me a minute to try and remember exactly what was going on with mine. I think at one point I had it figured out. I know by going back and doing the setup on the gov (after reversing the servo in the radio) it worked perfect.

I agree with Jeepcj. Your curve in the middle is too low and you are shutting down the governor. I wouldnt go below 80 in idleup

When you are checking operation on the bench. Make sure you are checking it in idele up/ stunt mode and the green light never goes out throughout the whole throttle/collective stick movement.

another thing to check. If you setup your gov with the ATV's on throttle at 100% each side, and then had to adjust the ATV's to get the throws right. It might be tricking it into thinking it is below the threshold, and shutting down. Just something you might want to check.

Thank you guys for your suggestions.
Bob, can you please explain your last suggestion, cause I think I am missing something.

You mean, first to set the governor channel ATV's to the desire position (60% for example) and after that (with the throttle ATV's at 100%) make the throttle travel setting?

My thought was, if you setup the gov, and the ATV's are at 100% for both sides (low and high) and then you setup your throttle servo. maybe you found that you needed 110% ATV's or maybe 80% on the ATV's
I was thinking that, if setup at 100% and changed, The gov might be thinking the throttle stick is someplace other than where it is actually at. Maybe enough to drop low and kick off the gov.
These are just some thoughts I have, My wife usually does not allow me to have any thoughts at home, so I tend to compensate here ( I am only talking about thoughts here!!)

Xexe. Mine too.
I can understand now what you are trying to say. So If I set my middle point of throttle curves to high (70-80% like hampilot said), do you think that it will eliminate this case?

I think it could. What I would do though, If your throttle servo ATV's are not at 100% each way, go back and set it up so you can achieve this. That would eliminate the "what if thats causing it"
Then after the throttle is spot on, do the setup on the gov again.
You might be spot on right now, just looking for things to help you firgure it out.

this same crap happened to my 700 at first, I would go up and stall turn and come back to myself and the gov would allow it to over rev everytime, I reset the gov with my throttle curve set at 100-60-100 in St1 and it stopped allowing it to do that, and I never did figure out why, because it had been at 50 in the middle all along, but I guess its not enough?
