Esc defective?

[Reptielenfreak]

Hey everyone.
so i have flown the freewing f16 70mm v3 multiple times but she feels a little underpowerd. Calibrated the esc multiple times, swapped the EDF. But when i re watched motionrc live unboxing he shows and you can hear it makes 1 beep than 2 fast beeps. Throttle down and done.. mine just makes 1 beep than another 1 beep but never the 2 fast ones.. is the ESC defective?

Youtube video action of calibration @ 56:50

Hope you can help me out

I’ve seen very few defective items. I’d say 90% of things people come on here saying they are defective are usually user error. That said I bought two planes last week and one had a bad servo.

[Reptielenfreak]

A servo is a totally different item. Im just wondering why im not hearing the two fast beeps at all and what that means as an result.

[Evan D]

I know a servo is different, I was just saying it's rare to have something defective. As I said it's probably something in the way your ESC is connected or the procedure you are doing that is not producing the right outcome. Without seeing I can offer no specifics.

[Reptielenfreak]

Its a stock/out of the box freewing f16v3, connecting a 4000mah50c pack. Alle colors of the EDF and ESC matchup.
Stick up, connect battery, 1 beep.. another 1 beep than the jet "connects" where according to the video there should be 2 fast beeps. If i keep throttle up it go's into the little "dance" where the servos move and when i keep throttle up then i will enter the esc "menu mode"
I will try to get a video uploade if thats whats needed

If radio is Spektrum try increasing your throttle channel travel to 120%. Spektrum transmitters default to a 1.9ms maximum pulse length at full throttle and that isn't enough to trigger all ESCs to enter calibration mode. Many ESCs want to see a 2.0ms (or longer) pulse.

[Reptielenfreak]

Oke, thanks for the tip i will give it a try as well.

it is a spektrum NX8 with a spektrum AR631 6chanel reciever.

So again, acording to the unboxing video on youtube from motionrc the second beep should be 2 fast beeps. Mine is just doing the slow beep until in connects and eventualy go to the ESC menu. So i throttled down before the menu is entered

[Reptielenfreak]

Another short of the beeps, it sounds like the 2 fast beeps come when the jet is connecting. But could be me

Do you have a spare 80amp esc, say in another plane that you can try ? Also do you have the throttle trim on your tx at its lowest setting, if not try that first then try another esc. I take it you have read through this, but just in case https://cdn.shopify.com/s/files/1/10...iles/fwesc.pdf. If the spare esc works ok then you might have to reset your current esc and try again.

[Reptielenfreak]

I do not have a spare ESC. Also i wonder if lowering the trim (now its on neutral) making a difference in "beeps"

Does no harm to try it!!! If it makes no difference then perhaps reset the esc to default settings and try again. When you try again you will need to recalibrate the throttle. Just out of interest check the throttle curve in your tx menu for the F16 to ensure it goes to max on full throttle. Do you have access to a power meter so that you can check max amps and watts output on full power and check this against the edf motor specifications to see if it is developing the power you need. I do not know the power output of the Freewing edf unit as all my 70mm FW edf planes , BAE Hawk, Rebel, F16 V2, SU35 and ME262 have the FMS 70mm 12blade edf unit with the 3060 1900kv fan 6s lipo. 80amp esc 2.5 to 2.7kg thrust. The F16 weighs 2.1kg incl 3300mah 6s lipo and has plenty of power.

[Reptielenfreak]

I did the reset, went to the menu tone, then waited till beep 8. Than throttle down. But it didnt cause the "beep-beep" to be on the second time.

But you guys hear it to that the "2 beeps" are during the cycle of connecting process of the jet right?

I did install the fms 70 3060/1900 but at the end of 3 flight during desending for a landing i had to push to 80%throttle just to not crash it on a 3.30 minute flight and landed the jet with +-3.76volt per cell.
this was wierd to me as well because twobrothersrc spoke highly of this edf. So installed the old freewing edf back in but then realised i was missing the double beep tone in the beginning.. it seems to be like multiple beeps away from what is told by motion rc

I will check the curve but i think its fine because i didnt changed it. Tnx gor the tip

What is the chipping sound in your video, a bit like someone clicking their teeth. Not the beeps which do not seem right to me anyway. When you go full throttle then connect lipo you should get 2 bleeps, move throttle stick to zero you should then get 6 bleeps one per lipo cell )and be good to go, I do not hear that. The sounds I hear are not as described in the esc manual link I gave you. I normally fly 3,5 mins from take off to landing on mixed flying with around 20% left on a 3300mah35c 6s battery. Fly more aggressive then I am pushing my luck beyond 3 mins. Here is my first flight of my F16 with my fms fan 3 mns take off to landing 28% left for a comparison with your flights. Do you have any other 6 cell capable esc 50,60,70, 80 amp or more . If so try it and listen to the beeps. If the beeps are correct then it looks like you need a new 80amp esc. https://www.youtube.com/watch?v=OgwHHe_Lk4g&t=23s

So i did the reset again, throttle curve is fine and the trim al the way down. Calibrated it because the stick now reacts on the lowest trim setting as soon as i touch the stick.
But its still not really puching it. I think i will order a new ESC because this thing just doesnt feel right to me at this point.

Fair enough. Let me know how you get on. Once the new esc is working ok adjust the throttle trim low point to a position to suit your thumbs. You might check the cells resistance on your lipos just to make sure the lipo is up to scratch and you do not have a cell on the way out,

[Reptielenfreak]

Preferable the throttle trim should be at center point right?

[paulrkytek]

Not necessarily. I prefer a a little movement in the stick so that I can put my thumb on it and there is a little bit of give before it bites and adjusting the trim allows you to select the point you are comfortable with.. The bite point is up to the individual. I end up somewhere between middle and bottom and adjust it so it is the same on all my planes
