Mike, when I get that far with mine I will make a box section with the three pieces. hole at the top towards the front of the boat, two side pieces coming down glued to the bottom and back of the boat but be careful the side pieces are tapered, I think to suit the transom, hope that helps if not i'll try to get a picture on tomorrow

regards Jack.

thanks i was miles off.

So I take it fits tight against transom, and 3 little cutouts needed

Lastly I could use the middle part ( part with hole ) as guide on underside of hull  on where to drill the hole for the rudder

thanks again , a real big help

Mike the only reason I've marked the cutouts is because I used some strengthening pieces of timber along the joints

Have a look at the picture Mike, it's a side view of the upside down u as you call it, it's just a support for the top of the rudder tube

 Hi guys,
      You are both doing really well for your first boats keep it going. My first boat was a Trawler "Endeavour" bought as a rebuild and boy did I have some fun and games sorting it out, the guy who built it had fitted everything in places that you could not get to (moral of the story is put the servo, steering arm and electrics in the hull before you fit the deck and make sure you have access to them when the deck is fitted). The servo was to one side under the deck and the complete steering arm and gear was also under the stern deck, I had problems with the steering due to the servo arm and the rudder arm not being parallel with each other this meant that the rudder moved further in one direction than the other making the boat interesting to sail (especially since it was my first boat). I duly set to work to realise that it was impossible to get at the linkage I ended up removing the Trawl gear framing and cutting out quite a large area of deck at the stern using a dremmel, I was then able to relocate the servo in a straight line with the rudder and make and fit a decent linkage to the rudder arm and servo which was adjustable to enable getting the two arms parallel thus curing the steering problem. As a belt and braces solution the opening that I had cut into the deck was trimmed in wood to create a rebate to carry the now removable stern deck, this was screwed down onto the wooden frame and as the deck was planked you could hardly notice. Great advice about walking away if its not going right also using the same manufacturers paints. Hope all this helps and if I can be of mor help with anything else send me a pm.
       Cheers,
           Peter. :-))

Thanks Peter and yes it all has to go in before the sides are on, not much access to the rudder post after, just trying to make up the rudder out of a bit of spare brass

quick question,

The rudder black threaded axle part, its not threaded all the way down....

does it sit with bottom section outside and rubber o ring on inside of hull and how do you tighten the securing nut ( not threaded all the way down 0

If I have done  this completely wrong please correct me

ta for now


 it looks threaded all the way down but there is easily a 15mm section at bottom where its not




rougly how I am going to mount it, may need to cut sides down of wooden support

Look back to the post Davidjt did of his rudder fit, Reply 57, you can do away with the 3 pieces of ply, just make a spacer to cover the blank section that does not have any thread on the black threaded Rudder Tube.

The black plastic tube is fitted the other way around so that it pushes down through the hole and the large nut is used to tighten it to the top section.

The top section then has to be above the water line.

Get the angle of the prop right and get it where you want it...drop a couple of spots of superglue to hold it in place,tape up the hole on the outside of the hull,put some spare 5x5mm sections around the inside of the hull around the propshaft and simply fill in with Epoxy....when set remove tape from outside of the hull and simply use filler to fair out where the prop shaft exits the hull

Forget the boat. What about the T.Rex Electric Warrior album in the very first pic! What a classic!

Seriously your model is coming along great and looks the business.

I think you're referring to the rubbing strake / half round fendering. O0
 
It is available commercially - I just used the broken fanbelt from a tumble dryer for mine, but not in that position, mine goes around the upper edge of the hull - see my thread http://www.modelboatmayhem.co.uk/forum/index.php/topic,47660.0.html

Great thread Mike!
 I'm following this with interest as I am also on my first boat. I'm learning new words and things as I read.


  I'm suddenly aware that my prop shaft will be completely below the waterline. Propeller end (obviously) and interior? I notice that the props in the pictures point down and that the other (motor) end is above the waterline. I wanted my prop to be vertical and thought that I could just use a universal joint! Will grease in the outer tube be sufficient to stop leakage?


Keep up the good work Mike and let's hope it helps reduce your blood pressure!     U2
