Bob

What is the operating voltage and max amps of your speed controllers?

Paul

[Bob Abell 2Participant @bobabell2]

Hello Paul

The ESC`s are……7.5v to 12v

50 amp…….and 70 amp for a burst of 5 sec

Just acquired on loan….

12v batteries 1.2 Ah and 2.1Ah

So how are we lookin`?

Bob

[Paul TParticipant @pault84577]

Hello Captain Bob

Looking fine, nice, simple and straight forward, where did you get the speed controllers from?

Paul

[Bob Abell 2Participant @bobabell2]

Hi Paul

I got the lot from Howes Models

An excellent supplier

Bob

[Bob Abell 2Participant @bobabell2]

Got the system sorted now…..Hopefully

I know I`ve jumped the gun a bit, but needed to know how the drive chains pan out before finishing the hull

And the Rudder mech etc

Have the choice now between 7.5 Volt and 12 Volt available

Bob

Bob. The SLA batteries not really suitable for the motors and will not supply the current.

I would wait and use the Nimh batteries as you have set things up, and see how the boat goes when on the water before buying anything else.

I see that both esc receiver leads go to the receiver, presumably on different channels. Does this leave you with a channel for the rudders? You could get a Y lead so both esc can be controlled by the single throttle lever leaving the right stick for the rudder?? As a suggestion of course.

Hi Ashley

It was a good job, I only borrowed the batteries

THe big VGC sailed Ok on the 7.5 v batteries, and I don't really want to charge about the lake either

Thanks for your expert advice though, my mate

Bob

[Bob Abell 2Participant @bobabell2]

Working on the Rudder drive again now

The hatch is shown open and placed on the rudder shaft, just to show that the rudder shafts have top support

I like the chain drive method, it`s more in keeping for a ship of the future 50`s?

The chain and sprockets can be obtained from Hobbies Ltd

Hello Captain Bob

I like the chain system as opposed to push rods, it spreads the torque across a greater area and makes for smoother movement.

Paul

[Bob Abell 2Participant @bobabell2]

Pleased that you like the futuristic rudder drive, Paul

I know Ray likes the Mech

Hey up!….It`s 8.30 pm already

Time for my Tinnie………G`Night, Paul and all

Bob

[Ray Wood 3Participant @raywood3]

Hi Bob,

Enjoy your tinnie, yes I'm m a big fan of your chain drive to the rudders 👍👍👍

`Morning chaps

I was rummaging in the junk boxes this morning, looking for two really special nuts or screws to retain the Rudder Hatch, when I spotted these little Mini Clamps. Old memories came flooding back to the 70`s

Me and my pal, Dave Bailey were always looking for ways of making money. Who doesn`t? ….I hear you say

Our first idea was these Mini clamps. We tooled up for bending, punching, deburring and sent them out for Cadmium plating. We borrowed the Works Plastic bag sealing machine and bagged the clamps in packets of ten.

Then off to Ashton Model Shop, where we met the our friend, Charlie Jackson. He liked them and offered to sell them on the counter! We made hundreds of the little devils.

We then progressed to Turnbuckles for yachts. We made three sizes and once again, dreaming of elusive riches ahead, we tooled up.

Er….What`s that?….What`s with this tooling lark?

Glad you asked that. We had a giant Engineers Vice and removed the Jaw Tips and fitted an assortment of male and female tools.

It was great fun, gripping a sheet of brass and simply winding the vice jaws together and "Pop", a side plate was made! It cut out the profile and stamped out lightening holes and two assembly holes.

They were a little work of art. I hope Dave has still got one on his keyring, I try and get a photo of it

We progressed to all sort of projects as time went buy

More later if any interest is shown

Bob and Dave

[Paul TParticipant @pault84577]

You clever bugger

[Bob Abell 2Participant @bobabell2]

Thanks my mate

Bob

[Paul TParticipant @pault84577]

Captain Bob a true engineer.

The temptation would be to use a butterfly headed bolt but then you wouldn't be able to get the clamps close together because the heads would clash.

The long bolt allows for easy access when the clamp is in a confined space.

Your bench vice 'press' is a brilliant idea.I

I am officially impressed and would like to see some more examples of your ingenuity.

Paul

[Bob Abell 2Participant @bobabell2]

Hi chaps

Slow progress at the moment, getting down to the bits and pieces

The rudder mech is now finished and works well

Trimming up the superstructure to fit the wibbly wobbly deck!

Using the filler and sanding down….etc

The Control panel is next in line

A few photos to have a look at, especially for Doc Thomason

Comments are always welcome chaps

Bob

[Paul TParticipant @pault84577]

Hello Captain Bob

I can't speak for anyone else but I am looking forward to when you paint it, have you decided on what you are going to do.

Paul

[Bob Abell 2Participant @bobabell2]

Hi Paul, I was only thinking about the painting colour scheme this morning

First layer……Card with Rivet effect, similar to GE………The rivets are for interest

Next……Under coat…..Grey or light blue?

Next …..Silver spray paint, allowing some of the blue undercoat to show through?

Not to mention……Lots of vents, hatches, missile hatches, some open, some with missiles on view

Mine throwers?

Pipes and all sorts of tripe etc

Hand rails and doorways…..Some doors open etc

The world is my Oyster!

Plus anything you and Ashley can dream up?

All good fun…eh?

Working on the motor drives etc at the moment

Bob

[Bob Abell 2Participant @bobabell2]

Spent most of today, fiddling with the radio gear…….

2 MARINE ESC 50 with reverse and 2 MFA 850 Motors

Only about an hour ago, did it show signs of life!

Both ESC`s have an ON/OFF switch

When the motors finally make their minds up to run….I can turn the on / off switch off and it has no effect

Is this correct?

Bob

[Paul TParticipant @pault84577]

Are the batteries charged?

[Bob Abell 2Participant @bobabell2]

Hi Paul

I have a little light bulb gadget that fits the plug socket and is a good quick check

The motors run ok, but the system is chronic

Will have another fiddle tomorrow and a word with Howes Models

G' Night Paul

Bob

[ashley needhamParticipant @ashleyneedham69188]

Bob. Just a thought.  I believe you need to disconnect the red BEC wire from ONE of the ESC receiver leads.

Otherwise, the system gets confused by having loads of battery supplies.

Ashley

[Bob Abell 2Participant @bobabell2]

THank you Ashley

We've had this arguement for years now and I've debunked it so many times

Ive got the the four engined VGC cruiser and the Lady Jane proving the point so man times

I just wonder where the idea came from in the first place?

No doubt Mr Grimnasty will appear shortly

It'll sort itself out shortly…..Hopefully

all the best, my mate and I like your latest magazine offering

BOb

[Bob Abell 2Participant @bobabell2]

Let's think again….

The system is now working, both motors run together and independently

Rudder is OK

My query is…….Why are the in line ON / OfF buttons not working?

Bob

[ashley needhamParticipant @ashleyneedham69188]

the On off switch certainly supplies power to the receiver and presumably turns on the esc itself, so it’s a bit of a mystery.

If you were to disconnect one of the esc completely, does the other work ok including the on/off switch?

The bec power lead thing, if it works for you then that’s good, but I think that if you ARE having problems, it is just something to look at?
