Brutus

[Bob Abell 2Participant @bobabell2]

Hi Amy

Start up problems are a good thing, if only for gaining knowledge on the subject!…..and I've certainly learnt a lot in the past few weeks

My only problem now, is the motor which runs in one direction only, but I have an idea this morning

Scanning time!

When setting up the ESC, the instructions say that you need to hold the joystick position for one second

The logic system inside the ESC has to recognise the joystick position and is a slow thinker?

I think a re-set is called for……I did mention earlier that the ESC hesitates?

Fingers crossed

Bob

They are a bit odd..the ESC on my two brushless setups require the stick to be held down for a few seconds..they are aircraft controllers so I have to put everything down and hold the stick for a few secs, or the motor does not make the correct bleeping sound and will not go.

hesitation..mine does that.. it may be a feature of the angle or frequency settings ogf the motor/ESC?

[Bob Abell 2Participant @bobabell2]

Thank you, Ashley

So your stuff hesitates too?

We may have something there?

Bob

[Dave MilbournParticipant @davemilbourn48782]

Spanner into works time, guys. Why would aircraft controllers have cooling fans and reverse?
Frankly there is a technical term for the ESCs which you have – and particularly the instructions – and it is not repeatable on a family forum. They are probably intended for some type of vehicle – maybe a rock crawler?

Until I know that there is a 100% reliable brushless ESC out there with decent instructions and which has been designed specifically for model boats then I will carry on using brushed motors and my fleet of ACTion ESCs. I would fit two Speed 700BB Turbo 12v motors into this beast with 40mm props. I'll await credible notification of the existence of the aforementioned brushless ESC – o, and you can forget buying it direct from China, too.

[Bob Abell 2Participant @bobabell2]

Dave, I have already said, the ESC is for a car, there's no mention of an aircraft

I'm surprised you personally have not dived in with both feet and claimed the title….Brushless King of UK and made a name for yourself!

Afterall you are halfway there!…..The rest is easy!…..So they say

We need a website expert, as a backup for Ashley!

Bob

[Dave MilbournParticipant @davemilbourn48782]

Bob

Quote Ashley's last posting they are aircraft controllers

As for brushless, there are far too many different motors out there to stock even a reasonable sample. We were looking at a brushless boat ESC when I sold the business. I've no recent news of developments there. I have retired anyway (as I keep being reminded).

DM

[Dave MilbournParticipant @davemilbourn48782]

Yeah – OK – so I read it wrongly! Sorry Ashley and Bob, but the second para still holds.

DM (Currently having no fun at all with reinstalling software on my new hard-drive)

[ashley needhamParticipant @ashleyneedham69188]

DM. Quite right, aircraft controllers. One was on the Ecranoplan, so that obviously needed an aircraft controller and the other one was a similar scenario.

if Bob has car/truck type ESc they can be set to differ the timing for more tourque on startup and so on (I beleive) . the hesitation is odd though. No idea why.

Bob you ar a CHEEKY MONKEY.

Ashley

PS. Guru`s never retire, they just wear longer loincloths.

[Amy jane SeptemberParticipant @amyjaneseptember49770]

Just a thought.

Have you had a look on the RCME model aeroplane forum? They have bucket loads of stuff on all this electrickery.

[Bob Abell 2Participant @bobabell2]

Sorry Ashley

I mean`t to say…" We need a Brushless expert, as a back up to Ashley"

Meaning that Ashley is the only Brushless expert on this thread

Sorry if I caused you some distress

Not a Cheeky Monkey

PS………Thank you Amy, for your suggestion

[Bob Abell 2Participant @bobabell2]

More thoughts on the motor that runs in one direction only……Yawn….Sorry chaps

Having carried out the set-up proceedure many times, with the result being the same, there must be a weak link somewhere?

On ESC set up, the joysticks are moved to the Neutral, Max and Min positions, whilst a little setup button is held down. At these positions, the ESC gives the ok by beeping

The ESC is not recognising the forward position at the moment……Why is that?

I assume the joysticks at the setting positions, give a signal to the ESC via a rotary slider or whatever…….Yep?

The tranny is nine years old and the rotary slider must be showing signs of wearing out?

Now you're talking, Bob!

This morning, I'll try swapping the joystick conns at the Rc end!……..What a brill idea!

The outcome will be very informative!

Back soon…..Bob

[Bob Abell 2Participant @bobabell2]

Swapped the Rc wires over

The single direction motor is still single direction, but is going in the correct direction now

The other motor still runs nicely, but rotation direction has been reversed

At least we can take the tranny out of the equation

We are back to swapping the motor wires and can sail, but don`t like the set up

Bob

[Dave MilbournParticipant @davemilbourn48782]

I think you have a faulty speed controller, Bob.
DM

[Bob Abell 2Participant @bobabell2]

It looks like it, Dave, but I'll try resetting a few more times because the setting process seems to have tight timing schedules.

Actions need to be undertaken within 2 seconds and pauses need to be a minimum of one second, coupled with assorted morse code type bleeps

All good fun at the moment

Also, the gear has arrived for SloMo, which could be swapped around

Not in a rush to go sailing, as it is absolutely freezing outside!

[TelstarParticipant @telstar]

Bob On a brushless Esc I played with, If it was set up for use in cars then it could not be moved from forward to backward in one stick movement. If you went from forward to reverse, the motor stopped, then you had to return to center off position and go to reverse again to get reverse. The set up instructions with this particular esc explained forward to reverse on the stick actually went forward to brake, and engaged some kind of dynamic braking, (not needed on boats) and reverse could only be run from stop.

Don't know if this helps or just muddies the water more

Tom

[ashley needhamParticipant @ashleyneedham69188]

Bob. You know what I am going to say. There is time to order one and get it, use it and then the weather will be nice to sail the boat. You could probably disable any braking and etc etc. Having once swapped wires over to get a motor to run the right way round, you should not have to swap anything else about.

You are blatantly NOT having fun as far as I can see !!!!.

Ashley

[Bob Abell 2Participant @bobabell2]

First of all, Tom

I've read all about the fancy braking etc for car control, but the point is……One motor is running perfectly well, in both directions……So the other motor should run likewise…….End of story

Thank you for your concern….Bob

Now Ashley…..What are you on about?

At the moment, I don't want to get embroiled in a program card……..Too lazy!

I've got another pair of brushless motors complete with ESC's here to play about with………And looking forward to the outcome, because I'm about to sort out the problem, once and for all, by swapping stuff about!

I can assure you, I am not in the least bit concerned with the apparent aggro I'm experiencing

Just out of curiosity…..What does a prog card look like?….and where does it go?

Bob

[curlyParticipant @curly]

Hi Bob

There are playing card size.You plug in rx voltage & your esc in the top, then you set up the esc. There is a row lights that you can move with set up buttons, brake, battery type, cut of type, cut off voltage, start mode, timing mode,li-po cells,governor mode. l hope this makes some sense to you. I would send you a photo, but I can'nt get my head round that yet

Curly

[Bob Abell 2Participant @bobabell2]

Thank you, Curly

They look very interesting……Will have to get one as a last resort backup lifesaver thingy!

Have had a reply from the Brushless supplier

It just says…."Swap the wires on one motor"

Which means there is not a problem at all……Just needs a bit of fiddling?

Bob

[curlyParticipant @curly]

Hi Bob

They always say, sometimes it is the simple way, lets hope it works for you. Myself I'm new to the brushless, and it does take some getting my head round. All the best

CURLY

[ashley needhamParticipant @ashleyneedham69188]

Bob. I expect you to sail this thing over the next two weeks. I am going to the I.O.W next week and will be looking forward to coming home and reading that it has at least seen the water again. Good or bad. Or I shall be V cross .

Its all theory so far. I would have had this zooming about as soon as the hull was sealed, just in case there were unseen issues (obviously not that I would expect any form Paul`s design)

Consider this a good telling off. Do I have to post on the Slo-Mo 2 "Ellie" thread as well????

Ashley Capt`n STERN.

[Bob Abell 2Participant @bobabell2]

Hello Ashley

I must admit, I've been a little laxidasical lately, sailing Brutus

The maiden voyage is still fresh in my mind!….and you know what they say?

Once bitten, twice shy!

But I'll make a special effort now…..For good reason…..

On a top secret mission at the moment, with Paul……Shhhhhh!

Have a nice holiday

Bob

[Bob Abell 2Participant @bobabell2]

Hello Ashley

Decided to sail Brutus today….Just for you and for another reason

Sure enough!……Brushless motors are playing up again!

Got onto the suppliers

The man said…… ".For 7,2v supply, it is already set up!….Simply connect up and go…..No setting required"

He also said…….".Don't use a tranny with the ratchet type gymbal,,,,,,,,Use the Elevator stick….To make use of the self centring feature"

Reset the good motor just to check out the proceedure on the Elevator stick and it worked ok…..But this motor was ok on the original setup

Tried the troublesome motor, but it didn't work!

I suspect the Esc is faulty

Will wait now for SloMo to be wired up and follow the latest instructions exactly

Don't want to corrupt the new gear with old settings

Why don't the Brushless motor dealers issue intelligent clear instructions written in English?

There are thousands of brushless motor set ups out there, all running nicely…..So we only need the correct instructions

Bob

[ashley needhamParticipant @ashleyneedham69188]

Bob…I will have to repeat myself here, again… GET A CARD !!!!

The ESC`s may not actually be set the same hence your diffs.

Can you poss sail Brutus on one motor and then swap ESC`s about to see whats what?

Ashley

[Bob Abell 2Participant @bobabell2]

Thank you Ashley

The man at the shop said……The system sets itself……….Don`t need the setting button with 7.2v

I`m waiting to see how SloMo runs, before my next move

You will just have to be patient, young man

A couple of weeks yet

Bob
