Hi,I’m not sure if any of you are able to help me because this question is really a long shot, but I’m currently building two boats from plans Moccasin MM1062 and Fairey Marine MM791. Both of these were featured as build articles in Model Boats magazines at some point in the 1960’s (unfortunately I don’t remember the year or issue numbers) but I know they were featured because I had the original magazines…..sadly long since lost. Remembering the original articles motivated me into wanting to build the boats again and having the articles would greatly help me to build them. If anyone could help me at all to locate these articles as back issues or photo copies it would greatly assist me.<!– toctype = X-unknown –><!– toctype = text –><!– text –>

I think that you are a little out with your decade as while I couldn’t find 1062 in an index I compiled from the Model Boats my Club has, I found 1036 dated in 1969 and 1066 was early in 1970. MB used consecutive numbers so perhaps that narrows matters for you.

I have a listing for Fairy Marine indicating it was not a plan but simply a drawing in the magazine 1962 pages 68 and 126 .. I’d guess that would either be January or February issue.

I could organise a xerox copy of the second articles and in due course, after Xmas could hunt through the albums for 1062 .. bit tied up at the moment.

Hope this helps

Hi,

I am trying to get a boat to go faster.I put a larger 6V motor in it which develops more revs but when tried draws so much power that the wiring became very hot.The original motor has got some capacitors soldered across the back of it,so I wondered if these were for current regulation or to give motors more grunt.What do they do?

Steve.

Hi Steve

Capacitors are fitted to the brushes of motors to reduce interferance from the brushes sparking affecting the R/C equipment.

You don’t give any info on the motors (type/make), however if you want more power out of any motor, you will need to put more power in, with electricity power is volts X amps, so if you use the same voltage (6v) then you will take more current.

Since the speed of a dc motor is (nominally) proportional to the voltage I would have tried upping the voltage with the original setup (possably to 7.2v nicad pack) to get higher revs. higher voltage won’t kill the motor, but higher current will cook it.

Matching the correct size prop with any motor/battery combination is one of the most critical parts of fast electrics.

Hope this helps cheers

JC,

Thanks very much for your response it was most helpful, I appreciate you having a look for me and would very much like to get hold of a xerox copy of the articles. The reference numbers MM1062 and MM791 refer to "model maker" plan numbers. Vic Smeed did the original article on the Moccasin boat as he was the designer and Phil Connolly did the other article I think? again as the boat designer.

Anything that you can get me though that relates to these I’d be most grateful for.

On the Moccasin boat I’m about to apply the tissue to the hull prior to painting and the Swordsman I’m going to build it next year when I retire, so I’m trying to get the info now.

Regards

John
