What motor size to try with my 1:48 scale Corvette
« on: September 05, 2016, 03:58:02 pm »

After some basic motor advice. Going to be doing my first 'big boat'. Its a 1:48 scale castle class corvette. Hull is being made and on its way in a few weeks so just trying to work out what to start looking at for hardware.

Hull length is about 1.7m and single prop.

This is a picture of one I spotted at Haydock model boat show for reference:-



Experience on my other boats is that I would rather have the ability to go more than scale speed when you need to get out of trouble !

Any suggestions on what to look at. I prefer direct drive rather than anything geared. Ta !

Nothing worked out yet at all regarding power so its all up for grabs

Pair of MFA torpedo 800's would see her sail nicely.

1:48th scale for my ships. Large enough to show gratuitous detail, small enough to stay married.

If you can find a large buhler it is powerful and would give a good scale speed  Bill..

Single Torpedo 800 with about a 60mm Prop. Or an old Smiths Industries DC car blower motor. 12v or nothing at this scale. I am running one of those much hated Johnson 600 motors on a 6:1 in line gearbox on 6v, in a slightly smaller Flower class corvette. Good run time but the U-Boats can hear you coming!

Actually.  The thing I suppose I need to find out before any dicision is made is what size of prop is roughly correct for this boat. Hopefully the detailed plans that are coming from Dave Metcalf with the hull should have that information.    Bit of gueswork unti then I suppose.

hi there

just looking at an old drawing I did on a piece of plywood which I did for a Castle Class Corvette at 1:48 scale to be built at a later date - I am just measuring the drawing - 74 mm diameter prop seems a bit too big - I was aiming on between 55 & 60 mm diameter 3 blader prop - being driven by a 600 with a 2 - 1 belt drive between motor and prop shaft - I was going to use MFA belts n pulleys.

David,

I have a Castle Class in my den (seen here at Wicksteed Park Mayhem 2016)- I could measure prop/check motor if it helps - (I did not build it)
PS forgot to mention - flat out it runs way over scale speed..

David,

Might take me a day or two as I have to move my den around to get access to it! But I'll check prop & motor and let you know the detail
