Won't get up to speed

[Jomaba4308]

-Protos 500 stretch
-YGE 60A
-Brain fbl with gov set for 1900, 2100, 2300 rpm
-6s 2650mah 45c battery

I am getting the 5 beep error on the YGE with no blades. I try to spool it up to check governor and it cuts out for half second and it doesn't get past 1350 rpm. I have the divisor set to 5 and gear radio at 7.15.
Could it be a brownout causing the 5 beeps?
I have no ideas what could be causing the lack of power.
Please help.

5 beeps error is receiver signal failed, could be brownout but if the heli is just sitting there and drops out on spoolup. I would think it might be more of a wiring issue.

What receiver are you using? If spektrum sat wires are a common failure point.

Does the cutout happen at the same time each time or is it random?

6s lipo? Is it fully charged? If it were dead the esc would detect 5 cells and beep one round of 5 beeps on startup. Errors beep continuously when in TH. I am sure you know this, but not everyone does.

As far as not spooling up to governed speed try flipping to a higher speed when you spool up. Sometimes 30% throttle for gov setting isn't enough to get the motor going fast enough to hand off to the Ikon if using it's governor. If this is the case you can go up to 39 and the Ikon will still use the low speed gov setting.

Let us know a bit more about your setup, receiver, etc. and check for lose wiring, and look for any wires that might have damaged insulation causing a short.

The cutout is random, I checked all the wires including the Spektrum sat wires during the build and they are fine. Fully charged battery.
It's definitely the 5 beep error, not just cell count.
I have RJX FS0391hv servos on cyclic, maybe power hogs?
One weird thing during the initial setup, I had to use 35-31-30-30-30 in the radio to get flat 30 in the gov setup. I don't know if that might cause an issue but I thought I would mention it.

That's wierd but anything under 40 will be seen as speed 1. I had to set mine to 39 because initially the esc sees the throttle % you set until it hits a certain rpm. That's why I set mine to 39 as 30 isn't enough to get to hand off speed.
If you have the Bluetooth module you can go into setup and see things in real time. Of course I would remove the blades.

From the basic input screen you can see rx system voltage.
The basic gov screen will show you head rpm (as long as your gear ratio and divisor set right), throttle percent and whether the gov is engaged (engages at handoff). This should tell you if the problem is with the bec (voltage drop), signal (should go to failsafe levels...I think), Ikon gov picking up, etc.

Another option is to disable the ikon gov, and set the esc gov and see what happens. It shouldn't be browning out with servos at idle unless you have a really weak solder joint or bad connection.

I just tried disabling governor and running a linear throttle curve, no effect still hits 1300 and cuts out. Not rx brownout, the sats don't start blinking. I don't see the rx system voltage anywhere on the Android app but no sat blinking.

Maybe static? If it is a plastic Protos it needs a ground wire from the tail boom to the motor mount.

[Jomaba4308]

I just overhauled it with hv servos, CF frame and stretch, I never had a problem with the stock plastic frames. Can static build-up with the CF frame? If so where would I need to put a wire on the CF frame?

[flint723]

A quick way to see if you need a ground is to just check resistance with a multimeter from the tail boom to the motor mount. There should not be much resistance.

[Jomaba4308]

At the back end of the boom or the front end?

[deebee]

CF is conductive and heli should less likely to have static problems, but a wire between the tail boom and the motor mount would cure it.

The servo voltage, is under basic- transmitter setup should be on the Orange bar near the top.

Did you reset the error? When does it return?
Don't know if it would cause an error but it may not hurt to recalibrate throttle. Need to do it with the phase sensor (gov wire) unhooked, to guarantee the the ikon just passes the tx throttle signal. Also if the yge internal gov is on it expects a minimum amount of throttle over %50 to set the Gov each time (only does this once for gov store), if it doesn't get this signal and can't set gov then I might throw a receiver error? Don't know never tried it.
Anyhow when I hooked up the program card to reset the error I would check/reset the settings just to be sure.

You could try to provide signal to the esc with a servo tester. Pull the red wire on the esc hook it to the servo testers output and hook a bec or any 6v power source to the input of the servo tester. Then power the esc with tester at 0, after the cell count and armed tones you should be able to operate the esc with the know on the servo tester, if it fails this test you need an esc.

Barring a bare or barely connected wire, I don't know what else it could be. Maybe someone who has had this problem will chime in. If not you might ask in the yge esc sub-forum link to this thread, or in the ikon sub-forum?

Best of luck, and please when you find the problem stop back in and let us know what it was. That way next person with the same problem might find the solution quicker.

I started with testing the boom-motor conductivity and at both the boom block and tail case resistance was at .03ohms.

Next I re-calibrated the throttle with phase sensor disconnected, and now problem solved[emoji2]. I calibrated the throttle with the sensor connected on my new DX9, not knowing it made a difference because I didn't have this problem on my DX8. I must have been lucky back then.

Thanks for all the help, now I can maiden it next weekend.

Sweet, glad to hear you found the problem, hadn't seen that one before ......was really grasping for straws trying to figure it out.

Appreciate you taking the time to get back on and let us know you worked it out.
Often there are a couple people with similar problems and setups following the thread waiting for a solution, then without answer the thread goes dead and we are all left scratching our heads.

Good luck on your maiden, fly steady, bring it home in one piece.

I planned on going to the field to fly on Sunday but when I couldn't get the Protos off the ground I just didn't feel like going and flying the Mini Protos that is flying great.
