Ok. Club member has a twin prop teskoa.
2 escs action p40 (older style)
Runs off 1 x 4.5amp pb battery,with seperate rx battery.
On start up, one of the escs(always the same one, starboard) chirps and will not setup. Take the lead put of the p40 and put it in the esc on a spare channel, it works normally. Put it back in the mixer, and it sets up and runs. Turn it all off, and then on, and the same problem is back! Any ideas???

What radio set is he using?

I think these Action controllers are sensitive to starting up with the sticks in neutral etc. Check where the trim is for the two channels. If possible place them at the half way point. Also, try to avoid using the ratchet throttle channel if you can. If that stick is a couple of notches off neutral this can cause a problem similar to the one described.

Flysky 6 channel, self centering. Also tried on a spektrum dx6 and dx61, and a futaba

If you are using a computer controlled transmitter like the Spektrum6 or Flysky6
Do the mixing in the transmitter and disregard the P40. .

I did some testing for Dave on these mixers and they just didnt like Dx5 but the others were ok.
I have a similar problem with 1 of mine, I just gave up and used as 2 seperate ESCs.
That was on Radiolink and Spektrum radio sets.

hi there


First question is - what are the speed controllers you are using with the P40 mixer?


other question - is it a P40E the modern version?   This one - it has 2 little switches internally, which alter the mode set up - e.g. gives you a soft start when the rudders are moved and soforth.


Sometimes, using the 'old' P40s with certain Chinese speed controllers and certain English speed controllers, to get them to work properly you had to remove one of the red wires from the speed controller.  This is because it used to suffer an internal feedback problem.  On the new version I believe this was fixed.


The other thing/last thing I can think of is - you dont have one of the speed controllers plugged into the rudder socket do you?   As you look at the unit from above, the first set of 3 pins (should be ESC3)  next set of 3 pins down (should be rudder)  next set of pins below that (should be ESC2) and last set of pins (should be ESC1).


John - I hope that helps.

hi there


just an afterthought - have you tried unplugging the speed controllers from the P40 unit - and replacing them with 2 standard servos and see which way they operate - and how they operate to the stick movement.   This will give you a better indication of what is going on.   


If you go onto Component Shop, there is a PDF file, with a diagram of how the servos should operate whilst setting them up.


Just a thought.

John, both escs work when plugged direct to rx. Will try disconne ting a red wire when I don't want to through it against the wall!

All that will do, I believe, is disable the duplicated bec supply and I doubt it will make a change to the problem.

On the very limited info you supply on your escs, they are already and, at all times, "set up."
 With safety in mind designed to ignore any invalid powerering-up glitches in their inputs, check for a valid rc signal and work within the limits of valid rc signals.
 The esc chirping is telling you that it is not getting a valid signal from the right hand mixer output. The mixer isn't able to make sense of the receiver signals.

 I suggest take heed of colin-d's suggestion and Shipmate60's info. 
 Going further, you should find a Turnigy V-tail mixer will work and an old 40FM or 27 am radio will get it to work but not the mixer together hooked to a year-2k onwards 2GHz receiver.

sitting wondering, is this mixer you have, one of Craig Talbot's original mixers?


If so, these were originally designed to drive 2 servos which were connected to either a Bobs board or a resistance type speed controller.


You may have a job making it work with 2.4 sets.


Just a thought.

Yes it is a Craig's original

I will take pics sunday afternoon and post it up. Maybe a video!!! I'm going to swap out the escs, check the p40 on the bench, and ensure the 6v battery is not under voltage etc

Hi Klunk,


May I ask what speed controllers you are using?

Won't work with a change of speed controllers and it wouldn't work with a pair of servos & Bob's Boards.
 If you swap out the three pin plug of the speed control for a servo it shows by not cooperating.
 If you swap the two speed controller plugs the other one will give the audio & visual warning of an invalid signal.

The original P40 instructions or magazine article will explain you need the channel timing that you get in this this link
So the P40 needs an old fashioned radio to make sense of two sequential inputs. The inputs shouldn't overlap or have a gap in between. That's what happens with your 2.4GHz radios.

Ok new update
New action p40e got.
Both escs have red wire removed, and power switch left in on position as per instructions.
Relevant leads plugged into correct ports, around right way.
Relevant leads put into receiver correctly.
All runs off 1 x 6v 4.5amp battery for both motors,  with a 6v receiver pack with on off switch.
We now have both motors running forward, part motor will not reverse. Motors work correctly when steering  except port reverse.
Have swapped escs over, problem stays the same with port esc not working. 
Both escs work independently when put on rx channels for tank steering.
Next step, power 2 escs with independent batteries.

New New update.
Stripped everything out of the boat to bench test.
2 x New FR40 microgyro esc both red leads detached
Action p40e
1 x 6v 2000mah receiver battery
2 x 6v 4.5amp battery
Everything fully charged
2 x 545 motors
First set up
All esc attached to receiver. All working and powered up properly. No issues, checked on all 4 channels.
Set up 2
Action p40e put into receiver,with spare servos attached to replace esc, as per Instructions. All works correctly.
Set up 3
Instructions say to leave power switch to escs on, and only switch rx battery supply
Replace servos with escs.  Escs do not power up or acknowledge signal from tx.

Rebind rx on new rx.
Redo do all above
Set 3 fails again
Swap microgyros esc for mtroniks. Same results.
Swap p40e for second brand new p40e.
Same results.
Swap mtronics for electronics 30 and 43
Same results
Swap p40e for older p40
Same results.
Any ideas?

Put the red leads back in or they don't get power from the plug. Hence no diagnostic lights.
If you need to disconnect its B.E.C. then do it via the power jumper.

So why doesn't it work on all hhe escs?

That's difficult for me to say without being able to eyeball what you have connected or missed.

What I can tell you is the FR40 has a helpful red diagnostic LED that will flag a bad main power connection or faulty battery. To work, it needs its red connector back into the middle slot.

[Shipmate60]

Do you still supply FR40's Mike?
