Align RCE G600 governor woes

[RotorBlade]

Guys - sorry for re-visiting this problem (I posted about it a few months ago) - I'm hoping to get some more input as after trying various things, it's not gone away.
The issue is - raptor 50 Titan, OS 50 max fitted with an align g600 governor. All fuel line checked & replaced and proper clunk fitted (new) - header tank correct etc - no issues with fuel supply.
Engine tuning is good but virtually every time I come out of a loop, as I either stall turn or sweep a wide arc, the engine over-speeds quite alarmingly, just for a few seconds. Weird! Disable to governor and the problem goes away.

Suspecting a rogue governor, I bought a second-hand one from the BMFA - result = no change. The chances of two g600s giving the same problem must be minimal.
Now here is the really weird thing. I have a g600 in my 90, and it keeps rock steady revs throughout all manoeuvres.

Doing my head in. Any fresh ideas.
Thanks in advance
Keith

You could put the one from the raptor on the 90 to verify it works.

It could be the engine is running lean. When the governor shuts the carb if the engine is lean it will run on. If you are sure the main needle is adjusted properly then richen the low needle.

Engine running rich can give same symptoms, tool gov off mine to solve problem as i didn't want to run engine too lean.

How have you got the governor set in the TX?

The governor uses the gear channel (Tx is a Buzzflier BF8 - a DX7 clone with 8 channels). The Traveladj is set to the correct rpm to give me on or off capacity with the gear switch. Progmix then gives me norm - st1 & st2 headspeeds by adding a percentage to the basic number. This is exactly the same as the set-up for the 90 which works fine, by the way.

How far is the magent from the sensor? I have experienced something similar and repositioning the sensor closer to the magnet solved this for me. I set it as close to the sensor as possible without it actually touching and from then on, it worked fine.

Also, I'm not sure that the way you are setting the governor with travel adjust is the best way. Just try using the percentages in the govornor menu to set the desired headspeed. Only my opinion, but I have never come across the governor being set up with travel adjust, certainly with an Align Governor.

Travel adjust is fine... no governor menu on that TX anyways i think (well if its a clone dx7). Try turning your mixes off and using travel adjust only to get 1 headspeed. Setting both sides of the switch to the same number. Youll have to do the throttle stick calibration again by pressing the button on the front of the unit and pushing up on the throttle/collective stick. Calibrate it with your travel adjust set at 100/100 before you change it to the desired rpm. Report back...
I had this happen to me on my Trex 700 and as soon as i set it for one headspeed (no mixes) it behaved itself. If it does the same thing then its probably engine tuning. This may sound simple but please just try it and report back.

Thanks for that Lee - you're correct - no governor menu on the BF8. I had the first G600 set up originally on just the traveladj, so on & off was all I could do & it was still the same. Having said that, I didn't re-set the traveladj to +100/-100 when I installed the replacement (D'Oh - what a muppet!!) so that's something to try. I'll do a proper throttle calibration again, try that & if that doesn't work, I'll give the replacement governor a try without mixes. I'll report back.

To be fair - I did wonder about that. The sensor works, ok as in it turns the light off as it passes over, but I wondered if flexure in the frame could maybe move the sensor a critical distance and stop it working. Something else to check & report back. Thanks Gavin!

Theres ya problem Even when you add mixes you must first calibrate with default values and then change them to get the rpm you want. If you try that and its still the same then id say engine tuning or worst case a faulty sensor/unit.

Have you got your throttle offset at all? How have you got your throttle servo setup?

[Steve]

Are you sure the Tx doesn't have a governor menu?

Maybe you have to activate it in the device select options first before it shows up in the 'normal' menu?

But I'm not familiar with that radio, so just guessing.

Not totally sure what you mean by throttle offset Lee....

[RotorBlade]

Are you sure the Tx doesn't have a governor menu?

Yep - totally sure. Don't forget, the same make of governor works on the 90 perfectly - solid rpm all the time with the same basic system of gear/trvadj/progmix.

Well the bad news is.....no change!
I've re-set the throttle as per the book, took it out for a spin today and it's just the same.
I richened the needle by 2 clicks and then 2 and it seemed to get marginally worse.
Having said that, by then the tank was only 1/4 full. Could it be too rich?
I get something just over 10mins per tank sport flying (leaving the header full) so I didn't think that smacked of over rich, plus good smoke, good response from the engine and a cool base plate, so hopefully not too lean either.
The only other thing to check is just how close the sensor is to the magnet.
After that - I'm stumped!
