Bute, James PottingerPlan MBM April 2007.
« on: July 03, 2017, 12:39:23 PM »

Has anyone on Mayhem built this model?
I'm after ideas for motors etc as I only have the
plan.
A scan of the article would be helpful if anyone
has it.
I will attempt to put up a photo of the build so far
when my camera battery is charged.

Calmac Ferry Jim,
Cars go in where the gap is
onto turntables and then inside.
Semi scale and 1/75.

This was the Rothesay ferry before the Juno/Jupiter times and they have been replaced by a new Bute
that I think carries 60 cars Jim.

Hi David,
Thanks for the offer, but
Dougal99 has offered the same.
and he is sending the scan.
I think a couple of 380/400 should
suffice, so I will be looking that way I think.

i would allow space for a 545 or even better 555 on 12 v battery, if you need more zip, then its easy, 385 dont like constant heavy load, and may struggle in a blow

It's twin screw so a couple of 385's should
suffice.
It's less than 30" loa, and, being a ferry,
 scale speed is quite sedate.
I think the 555's would be a bit overkill.

Yes, it's actually quite a small boat. 385s would be more than sufficient.

I built one from Vic Smeed's Arran plan around 1968 or so.

The article from Model Boats - September 2012 recommends twin 385s connected with a single 15 amp ESC.  He also included a mixer to get counter rotation on his props but I'm not sure why, surely he could just have wired them up opposite?

The 2007 mag doesn't give any motor details.
I didn't know there was another article on it.

I think that it's a different build but still from the Pottinger plan. It was the September 2012 issue.

Nice looking model is that!! Will keep an eye on this one methinks :-))

As for motors - my first choice would also have been a pair of 385's.  More than ample enough to move this one about.  Maybe a pair of 30mm dia props would be sufficient too.  Not too large as to be over-scale.

The original Jim Pottinger feature was published in 2007 and republished as a free plan in the 65th Model Boats Anniversary Special in 2015.

The September 2012 issue of Model Boats featured a build article by David Heaps. His model used two 385 motors and he also mentions a mixer but then goes on to describe fitting microswitches to reverse the screws at extreme rudder angles. It's not altogether completely clear how this works. However a conventional twin ESC setup with mixer should work fine although a bit more expensive than David's solution.

I won't be doing steering courses with it %)
Twin props, twin rudders will turn it a bit
better than your average grey funnel O0
Before I go any further, I will stick the
Motors in and try it with some plastic props
before deciding if it needs a mixer and
some nice shiny brass (I assume 4 blade)
propellors.

4 blade props would be most suitable - the Raboesch ones will be fine and very cost effective.

One tip - try to mount the shafts (if still possible) just a little outboard of the rudders and have the props turning inward (port side clockwise / stbd side anti-clock as viewed from the stern).  The wash across the rudders is more effective than having the rudders perfectly in line with the centreline of the shaft.

It also enables the shafts to be withdrawn without removal of the rudders!

The shafts are in and the rudders.
The shafts are about a half inch
outboard of the rudders  so I don't
think we will have a problem.
