Hi Bob,

The Pacific Light I'm building is only 48" in length but will be extremely heavy.  My choice of motors (2) was I needed power and not speed, I also don't like using gearboxes as they add extra noise.

   Details:

   Supplier = Westbourne-models.com

   Robbe Power 1ooo motor

   Current amps @ max efficiency = 2.5 amps

   Maximum power = 10.oo amps

   Revs = 650

   Efficiency = 70%

   Weight - 1ooog (1kilo)

   Length = 96mm

   Voltage = 6v-12v

Suppressors - here you may have a problem. Normally we would fit 3 capacitors to suppress any electrical noise, however I have only been able to fit one, across the power terminals inside the motor as there are no external terminals. The motor is held together by two lengths of screw thread which pass through the full length of the motor, but these do make mounting them easy through 2 half height bulkheads.

Now if that hasn't put you off - the next bit of info will...

You will need to be sitting down for this ...

Cost = £37.99 + postage !

If you have used nitro engines before you may already have a motor. The electric starters for these engines use a similar motor.

I also intend to fit these motors into my Imara tug

Cheers - Ken

Hi Bob

This might sound daft especially with you and Ken talking about such big powerful motors but have you considered using geared meccano motors to drive the paddle wheels.

When geared to the slower speeds they are very powerful and should rotate the paddles at the right scale speed, they will also take up less space in the hull especially as they will be sitting transverse.

By the way the build is looking very good.

Thanks Paul

Don`t really fancy Meccano motors for some reason.........I`m looking for something brutish and powerful.......especially for the prop

The paddles will have a chain reduction drive anyway.

I don`t want to crawl round the pond at a puny scale speed.......not that I`ll go charging about like a Loony!..........I like the idea of getting somewhere fast when I need to!

The Robbe motors sound ok but not impressed with the capacity nonsense!

Regards Bob

Hi Bob,

Just had a thought about the suppressor.

There may be a way of fitting without opening the motor.  Not sure of the name I think they are "Scotch Locks", we use to use them on cars to connect accessories without cutting the wire, don't know if you remember them. Still available at Halfords and the like.

Could also just "nick" the insulation, solder the capacitor lead on and then slide a little heat shrink on.

I agree the capacitors are a pain but I've already done them,  however when I come to use them on the Imara, I think I'll go with the nick & heat shrink idea. That way I'll be able to get all 3 on.

Ken

Hi Bob&Others,

Have you thought of using Wheelchair motors?they sometimes get changed for not much reason,also batteries, so chat up your local Mobility Repair shop.

I also heard of a chap using car electric window motors, they have a right angle drive.

Hi Len,

I wrote a nice little reply there to your suggestion, but deleted it as I do not wish to be thrown of the forum or bring it into disrepute for bad language - may work for other people, but for me, from past experience with these mobility guys will give the idea a miss.

The window idea is a good one though.

Cheers - Ken

Another suggestion Bob, is the motors which raise the seats in the Ford Granada, up and down.

Thanks for that Alex.......I really want something more user friendly than that

Another thing is that the motor is only 1.5" above the inside of the hull!

I keep looking at the MFA 800 motors with mechanical controller?........Too small?

Hi Bob,

Quote : "the motor is only 1.5" above the inside of the hull" - does this refer to the center of the prop shaft ? - meaning you could fit a motor up to 3" diameter.

Your looking at the MFA 800, but reckon they are too small, can you fit two of them ? - with a belt drive as in the severn class lifeboat featured in MB.

When I fitted the 1ooo's, I did not have much height due to the angle of the shafts. The motor mounts were two lengths of ply glued each side of the motor.  The space was filled with silicone, motor wrapped in clingfilm and replaced.  Took 3 days to cure, but ended up with a bed that was a perfect match, absorb any vibration and stopped any noise transferring to the hull.

Cheers - Ken

Hey - its just another idea to ponder over, no need for a metal motor mount.

We welcome well written contributions from Website members on almost any aspect of Model Boating with a particular emphasis on practical hints, tips, experience and builds.

In order to maintain a consistent standard and format, all suggestions should first be sent to me by Personal Message for approval in principle. Only a very limited amount of time is available for editing contributions into a suitable format for placing on the website so it is important that the material is well presented, lucid and free from obvious spelling errors. I think it goes without saying that contributions should be illustrated by appropriate photos. I shall be happy to give advice on this.

The Member Contribution area offers space for short informative mini articles which would not normally find a place in Model Boats magazine. It is an opportunity for Website Members to freely share their  expertise and experience but I am afraid that virtue is its own reward as there is no budget to offer more material recompense!

I look forward to receiving your suggestions.
