A pal is building a Clyde Puffer,and I can only find  one similar build here on Mayhem.However,that build uses a Decaperm 6 volt motor,which is pretty expensive.Could anyone advise him of any alternatives to use please? I am not sure which scale his is, so could replies include suggestions for both scales of Puffer please?
Many Thanks

Mick,
you may want to check the size first as there are kits and semi kits out for them
in 1:72, 1:32, 1:48 and 1:24th scale.

if it was a decaperm you would be looking for something similar to a 545 geared motor

easy-ish solution is a motor that is about 2500 to 3000RPM and the same diameter as the prop
they were not fast they just puffed along

Thanks gingyer,
he is bringing it round tonight so I will check the measurements.I just wanted to be forearmed with some info to pass on to him.I must admit I had forgotten about the motor to prop size comparison!
Thanks,
Matey,
Mick

a 555 or 585 will do admirably for the Mountfleet or the Calder craft models........that's what I put in the caldercraft one and would do with the Mountfleet if a buhler wasn't available....they were a max 8 knot ship anyway and you don't want the ol gal to behave like a Shannon, lol

I used an MFA 500 on my  caldercraft one and it chugs away quite nicely.  Also ready wired and suppressed so saved me a job that I am useless at.  Amongst other jobs I am useless at of course.

Put a buhler in my 1/24 highlander & a 60mm prop shop prop pushes it well with power to spare regards Bill.....

I use a Mabuchi 555 on my Mountfleet Highlander, 33 inches long. It is fitted/ballasted with 2 x 12V 5 A/Hr sealed gel batteries and goes for ever. 2 hours round the lake this afternoon and still lots of go at the end.

Thanks Guys,for all the replies.
I have since found out the sizes of his boat,his measurements not mine in old English


33 and 3/4 inches long, and 10 and 1/2 on the beam. does this make it 1/32nd scale please?


Its strange, because I saw one as a diorama the other day and those measurements were very slightly different  at 33 inches long and 7 and 1/2 inches Beam.
I also have a four bladed prop of 1 and 3/4 inch diameter which seems ok?

[Netleyned]

1/24th methinks.
Original puffers were about 66 feet loa to use the
canal locks.

I have a 1/32nd Mountfleet puffer, and it is powered by a 550 motor, the model weights about 4kg when all the batteries are in it. It still has a good turn of speed when required but equally goes along nicely at scale speed
