So while awaiting the great Warwick Show report Ive been swanning(see other post re Swans) around on the loch and towing me mate`s Thames Barge on a cold November afternoon.

I finally got suitable "Alaskan" weather for the Coastguard Cutter Springer to feel at home in

Try a Fishtail Rudder ,then with one motor it will spin on the spot,forward and reverse.
Look at Fishtail Rudders and a sketch on Model Boats Forum, Look for the Dennis the menace photo,Len ::)
My Springer is there also, Gazunda ( Do you get it? Gerry Springer!)

Right then this is dangerous territory for me cos me now building a springer,now Me being ME power mad has decided seeing I have a Schothel Drive at my disposable I wonder would it do in a Springer is it allowed or is it classed as cheating or do I get away with it cos I am moderator!!!!!!!!!!!!!!!

A Schottle drive Springer... hmmm, an interesting thought!...
It puts you in the Super Springer class and you might get frowned upon by the regular Springer guys..

I think everyone would be interested in your 'pull' results with a Schottle..

Is it the small Graupner drive or the large version?

chingdevil · « **Reply #680 on:** November 25, 2007, 09:04:15 pm »

Stav
I agree with Toes the drive would class it as a super springer, it would not be frowned on by me I think it is great people try out new ideas with the basic hull. The drive might even stop the springer diving, it would be interesting to see in action. What would be the turning circle of the springer with that sort of drive???

Do it..Super Springer Stavros

. Turning circle wont be improved IMHO but I`d like to see how the top speed compares. I dont seem to have the diving probs due to rearward balance, agreed it doesnt look right at rest but.....

Arrow, the turning circle wont be improved... it will just go round and round on the spot!...

Arrow5 · « **Reply #683 on:** November 25, 2007, 09:45:27 pm »

That is what I meant Toes

, mine rotate with the cooling water outlet as pivot point, pretty tight circle but off centre as you say compaired to the Schottle.

Stavros · « **Reply #684 on:** November 25, 2007, 10:18:52 pm »

So the consenis of opinion is to go for it then

...Hi Stavros...

...All the Best...Norry...

A GRP hull????????

With a Schottle drive...

.. A Super 'Sport' Springer....

Arrow5 · « **Reply #687 on:** November 26, 2007, 09:55:31 am »

Next the "Formula 1 Super Springer" in carbon-fibre......we need pictures Norry,or do we send a mole to infiltrate the top secret Skunkworks in Greenock ?

glennb2006 · « **Reply #688 on:** November 26, 2007, 01:39:58 pm »

Aha,

it would seem then that as a holder of one the rare GR springer hulls I am in a somewhat unique position, thanks Norry by the way, it will be fine as it is.

Now, just got to stick a powerplant in it and we will be off.
Was thinking of a glow motor but will stick with electric I think......

...Hi Guys...

I,m Glad you like it Glenn...Pictures of the build is now compulsary,,Only to make all the wooden Springers Jealous...

As for pictures...These are all I took prior to Packaging & Posting off to their new owners...This & the other one i have already posted on the forum...

...Best Regards...Norry...

glennb2006 · « **Reply #690 on:** November 26, 2007, 03:45:50 pm »

OK, I can probably work out how o stick some photo's up as it goes, it is going to be a recovery boat for the race boats so it is not intended to be built to look particuarly good, function over form on this one.

Glenn

Are these available to the general public?

or do have to wait for wearboats to bring it out?

glennb2006 · « **Reply #694 on:** November 27, 2007, 11:34:42 am »

So here we go with the build. I have looked through the thread, can not find the bit of info. I want, hidden deep in the 35 pages somewhere no doubt!!

I would like to know prop shaft position please, also, is the rudder position critical and is the "keel" for want of better description, that I have seen on some models required?

Thanking you.

By the way, if anyone is interested, planning on running large prop on mine and have geared down drive to fit. (Belts and pulleys)

Glenn

chingdevil · « **Reply #695 on:** November 27, 2007, 12:20:53 pm »

Hi Glenn

I think the prop shaft position is set to give clearence to the prop from the underside of the hull. Remember it should be as close as possible level in the hull. I have read that the skeg is not important unless you are going to play football, saying that both of mine have a skeg fitted it helps to put the prop further back and support the prop tube. The position of the rudder should be so the rear edge of it is just forward from the stern of the springer. The maximum size of the prop for a standard springer is set at 1 1/2 old money, about 38mmm. A bigger prop will put it into the super springer section.

I do have some drawings, in CAD format of my first springer, if you want printouts of them PM me your snail mail address.

If you need any more information, just ask.

Martin (Admin) · « **Reply #696 on:** November 27, 2007, 12:24:37 pm »

Has anyone tried angling the prop tube downwards to see it it helps prevent the ploughing tendency?

Martin.

Arrow5 · « **Reply #697 on:** November 27, 2007, 12:49:04 pm »

You mean downward at the motor end ? I`ve got a couple of degrees that way, ie upwards at prop end. I don't know if it helps because I trim mine to be nose up when at rest. I suppose I could repaint the waterline at an angle instead of parallel with the deck.

Martin (Admin) · « **Reply #698 on:** November 27, 2007, 01:26:29 pm »

I was thinking downward at the shaft is angled down toward the propeller .... motor higher than the prop........

Marks Model Bits · « **Reply #699 on:** November 27, 2007, 02:58:47 pm »

Our springers have the propshaft angled downwards (motor higher than the prop) and both mine and Hannah's boat doesn't seem to behave any differently to anyone elses.

Mark.
