That is five  UK Pounds, under US$10.  Toesup or any of the US expert Springerites will chip in with prices and sources. I think I`d glass the outside too if you have the stuff anyway. Use lightweight cloth (model aircraft wing skinning grade) just for ding-proofing more than strength, if you can add pigment it`ll save some trouble. Resin alone will crack as the wood swells and contracts, needs the glass to stabilize it.  I`ll try and find a link to the pontoon "Get-um-backer", anybody ????

A 'cheap' 540 would be the Tamiya motor from Tower Hobbies @ $11.99 http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXPML4&P=7  ;)

Thanks for the link Toes.

Is the heat created by the brushed motor going to cause a problem with the receiver or ESC.

Or should I be looking at a brushless motor :-\

Nope...

Templeton, Mrs Toes Springer uses one of these (direct drive) and has no heat issues. Just keep the RX away from the motor and ESC in case of any electrical interferance.

Hi dudes !....i do now watercool my springers if i know i'm going to do some heavy duty pushing......I have so far managed to fry two 540 motors :'(

      No problems now i've got the wet stuff going round the motor . in fact with the old fashioned water pickup behind the prop, when fubar is pushing hard the water outlet looks more like a fire monitor O0

           regards....bob.

Thanks Arrow. O0

Mine is setup like the Big BD but i sure like the looks of the Diversified boat ;D

I guess I could make the same using florist foam.

Is there a thread that I haven't found with the steps to installing the motor, cap and drive for a Springer?

No, no, no, NOT florist foam. If it is the same as the UK  "Oasis" it is made to absorb water !  You want expanded polystyrene foam as used in the construction industry. Comes in light blue or pink.   Dow-Corning is one is one manfacturer, absorbs less than 1% due to closed cells,easy cut and sanded with normal tools or can be hot-wire cut.   kids swimming pool floats and Boogie-boards are another source of suitable material , nice multi colours to !   The be all and end all source of Springerism is on www.RCGroups.com in the Boats section under Dock Talk, Springer Class. The history, design, how to do it etc etc.  But dont be leaving here, we still want to see you here with pictures and progress. O0

Thanks again

I don't know what I was thinking :embarrassed: I knew florist foam absorbs water in the back of my wee brain.

The boogie board might be just the thing to cut and shape to fit O0

I'll check RC Groups right now as I'm already a member.

Here's the hull with a layer of 7 1/2 oz glass on the whole inside and bottom and a layer of 1 1/2 oz on the sides.
I'm going to leave the natural color because of the name of the boat and what it will be used for

Nah ! somebody has done that I think.   I thought with all that lovely coloured wood it is just screaming to be a retired tug skipper`s luxury runabout :police: white Yottie`s hat of course. :D

Arrow

I've built deep vee racing boats also and my next one is going to be a shovelnose hydro along the same lines. I really like the look of deep natural wood ;D

Andre

That's the idea and i've got the perfect name for it too ;)

Funny you should say a shovel-nose. When I was building my Sprub I thought if I painted it blue and silver and put an open cokpit instead of a conning tower I`d have a Springer K4 ala Malcolm Campbell 1939 record boat. {-)

I'm going to mount the motor as horizontal as possible but was wondering is there a good distance up from the bottom or down from the top to have the propshaft at? :-\

Well you`ll need a block of wood to sit the mount on and allow for a water-cooling coil (recommended even in UK climate). I`ve taken to siliconing the motor mount in a  box filled with the stuff and held on position until cured (24 hrs). Generaly keep the motor low down and a straight shaft, with u/joint of course, prop clearance at other end will be a clue. Dont angle it "up" at rear to cure diving, it`ll just cause a roostertail. Diving best cured by rearward ballast to give about three or four degrees bow up when static. Hope this helps, I`ve been known to be wrong before >:(

This may help you with your 'line' for the drive / motor...

Thanks Arrow & Toes

Arrow, It's good to know not to have the drive on an upward angle. I was going to use a straight shaft but I'll put in a U joint per your suggestion O0

Toes, I had the springer plan you sent printed out full size last weekend and have been taking the measurements off it, but it showed the angle of the shaft on a downward angle that is why I asked the question. Good article on the testing. :)

A slightly shorter prop-shaft than shown on Toes` plan will bring the motor back to the deepest part of the hull. By the way we demand pictures of your progess >>:-(
