Commodores Challenge

Thank you Richard and Ashley

Would you believe it?

What now?

Just had another read of the Controller instructions and it says……..

If the motor runs in the wrong direction," simply swap the wires over! "

The Northern phrase for this is….." Worra Gorp! "

…you knew that really Bob…but it may still have meant a change of prop, and the low power reverse is also not an obvious feature to have on an esc.

The first trial run

Our friends next door. were more than happy for me to test sail the Launch in their new Swimming pool, as they had a very intelligent five year old son, who was highly delighted with the idea

Because the cockpit was in position for the test, the battery caused a lean. To counteract this. another battery was taped to the opposite side

The model sailed well and was very responsive to rudder and throttle.

Had a small leak in the bows

Kayden the little boy is only 5 years and he mastered the controls, almost immediately!

We had a very nice afternoon

A few photo`s……

Surely the trouble then would be Bob that pushing the stick forwards will make the boat go backwards!

I'm sure you have to reverse the throttle function at the transmitter as well as swap the wires over.

She seems to sit nicely on the water so I guess you now need to see it moving at a good pace across the water?  You may well have a convert with you and be able to take on an apprentice.

Blimey. Richard

I need to have a sit down and give the matter more thought

We are not out of the woods yet!

Bob

[Bob Abell 2Participant @bobabell2]

A late entry

[ashley needhamParticipant @ashleyneedham69188]

Bob. There are not many combinations to try to get the thing running on full throttle!

With the transmitter channel ‘normal’…ie, with the throttle not reversed) if you connect up the esc and put the throttle forward the motor should be going full throttle on forward stick, as a starter, so just swap the motor wires over at this point to match the prop (so it goes forward) and that should be that!

Ashley

[Bob Abell 2Participant @bobabell2]

Thank you Ashley

I really can`t get my head the around the problem with a quickish solution

When Richard suggested, just swap the wires round, I was surprised that I didn`t think of it myself and when the leaflet said the same thing etc

It is possible that the motor is going the same speed forward or backwards?

I could just leave it, afterall it`s not a Racer

But I think I`ll order a new prop?

And Bob`s yer Uncle

Bob

[Bob Abell 2Participant @bobabell2]

Got the hull lashed down in position for repair, but now realise that the lower hull is sealed off from the upper section!

Will have to turn her over and cut access holes in the top floor for a good dry out

Not much of a problem,

Bob

[Bob Abell 2Participant @bobabell2]

Just look at my ridiculous collection of Adhesives!, it would make a nice jigsaw picture?

Well chaps which glue is best for sealing dry joints?

I fancy the Monkey stuff as it`s always on the telly

The true power of advertising, eh?

Ashley, if you only reverse the cables to the motor the motor will turn the other direction for the same movement of the stick. Therefore the boat will go backwards when you push the stick forwards.

Try it with any one of your boats, simply swap over the motor wires and see what happens.

[Richard SimpsonParticipant @richardsimpson88330]

Another way of doing it would be to change over the battery polarity to the speed controller but then again you will need to change over the motor cables to correct the direction. That is only of course if you can change over the polarity to the speed controller. Those with a BEC circuit need specific polarity.

If you only change one thing the boat will go backwards when you push the stick forwards.

[Bob Abell 2Participant @bobabell2]

Thank You Richard and Ashley for your suggestions

At the moment, this is getting a bit too much for me take in

The situation is so bazaar, I can`t comprehend how the problem has got so complicated?

Is the simple answer an opposite hand prop?

I can easily make one to prove the point

At the moment I`m in the process of sealing the hull

Bob

[Richard SimpsonParticipant @richardsimpson88330]

Bob, putting an opposite handed prop on will work however, if this speed controller is indeed set up to give a faster speed in one direction than the other the danger will be that you have more speed in reverse.

If you try reversing the throttle on the transmitter and swapping the wires over on the motor it will only take a few minutes and it will be sorted.

If you are not happy doing that and feel more comfortable with the opposite prop option then by all means buy an opposite handed prop.

[Bob Abell 2Participant @bobabell2]

Hello Richard and Ashley

You won`t believe this

I have not changed the wires what so ever, but the motor is now going faster going forward than reverse!

I can only think that the propshaft has had a tight spot and is now free running?

So it`s panic stations over and apologise for not spotting the tightness a bit earlier

Thank you Richard and Ashley for your very kind assistance

I`ve just got to sort out the front end leak and get back in the bath for an indepth test

Bob

[Richard SimpsonParticipant @richardsimpson88330]

At the end of the day I'm just glad you got it sorted.

[Bob Abell 2Participant @bobabell2]

Thank you Richard for your assistance

Don`t really know why the prop was so problematical

It should have been a simple straight forward assembly in the first place

I think we had a few bum steers early on, which sounded so plausible?

Such is life. eh?

Bob

[ashley needhamParticipant @ashleyneedham69188]

Very easy to over-think these things Bob.

Ashley

[Bob Abell 2Participant @bobabell2]

Quite right Ashley

"Too clever for our own boots"

Another famous saying from up North

Bob

[Richard SimpsonParticipant @richardsimpson88330]

It reminds me of a very frequent conversation with younger engineers on ships. I was always trying to get them to think of and identify the 'bottom rung' of the ladder when fault finding and not try to start a few rungs further up.

My example was always an engine that wouldn't start and get them to ask the questions following their fault finding thought pattern. After we had invariably gone all around the houses discussing fuel filters, pumps, starting systems, pneumatics and electronics I would let them ramble for a while.

I would then simply ask "Have you checked that there is fuel in the tank?"

[Bob Abell 2Participant @bobabell2]

Thank you Richard for your logical engineering approach to a problem

In my case, I just assumed that the controller was at fault

As I had the same problem last year

I`ll have a look at the thread and see how the problem was sorted

I remember the model being very sluggish and is now in the Dustbin

I`m using one of the salvaged motors

Bob

[Bob Abell 2Participant @bobabell2]

No luck with history search on the Brutus 11 problem motor history and it was only July, last year?

Any way. the hull is now water proof……Famous last words…eh?

And can now get on with finishing the cockpit ensemble

Captain Bob

When is the official first sailing at Etherow?

Now that we are allowed to come out and play it would be nice to make the exhaustive trip and witness the event.

Paul

[Bob Abell 2Participant @bobabell2]

Hello Paul

I really would like to meet you at Etherow, but the busy active fun days of yesteryear are not apparent at the moment

There are no motor powered craft being sailed this season. due to the Covid restrictions, I suppose., only One Metre Yachts are to being sailed

I would not like to see you disappointed when you do call round

The official event takes place sometime in September and at the moment, I am the only entrant!

Will keep you informed

I think the event will not be very impressive, going off the last Challenge atmosphere, very sombre, but again the Covid Plague was very serious at the time.

When the event materialises, I will also take the Slo Mo 2 and the 40 inch VGC, which hasn`t even sailed yet, to give you something of interest to see, since you were involved with their building a few years ago

All the best, my Mate

Bob

[ashley needhamParticipant @ashleyneedham69188]

Covid restrictions on powered boats but not on yachts?

Why??
