gpzy, I used 1/32nd ply for the bottom and sides as per the plans, so I am putting a layer of cloth and epoxy for a little xtra strength. I suppose you could just go with epoxy and no cloth.

You can do either. My Murray River paddlesteamer has both; glass and epoxy outer and epoxy inner.

I used the Boatcraft system of the TPRDA/epoxy mix then, as soon as it had gelled, I sanded it over with 80 grit paper, wiped it down to get it clean, another coat of full strength epoxy with a layer of scrim glass cloth (seriously fine mesh), wiped over with gloved hands to smooth it out and left to cure. Human hands are wonderful tools for getting a surface finish fair.

A couple of coffees with choccie bickie later and a good read for a couple of hours, sanded it over with much finer paper and primed it with enamel undercoat and finished it as usual for enamel.

Tough stuff and hard wearing. Easy, just believe what the instructions say, NOT the local self appointed expert on all things.

Inside, I simply coated it with one coat of TPRDA and epoxy mix, and painted it over with enamel undercoat straight over the epoxy. Job done and holding up well.

In full size boatbuilding, epoxy is the best timber primer/sealer by far, followed by 'glass as specificed by the boat designer or the epoxy dealer.

An essential ingredient to doing a good job is the coffee/choccie bickie bit. It's called patience.

The rudder placement and size concerns me, any ideas?

Hey marter its looking great! the rudder would probably benefit from adding some area forward of the pivot point, to balance it so your servo isn't fighting the prop thrust so much. Try moving the center of pivot back to 25-33% from the leading edge of the rudder. Other than that its awesome.

Terry it looks great! Can't comment on the rudder because being a nooby i have no clue but I would follow JayJays advice. I just got back from a weeks vacation, so I have to catch up. I want to get it wet in next 2 weeks or so.

Hey Blutoh welcome back! I can't wait to see who's salty hits the water first, will it be yours? I've been away from RCG the last couple weeks busy with work and the cartoon runabout. I finished the prototype plans and I have the hull framed, sheeted, and the interior reinforced with glass strips and sealed with resin; as soon as my mahogany and obechi planks arrive I'll be posting photos and updates. I'm hoping the wood shows up by wednesday, so I can start planking over the 4 day weekend!

Great JayJay, I can't wait to see it. My running gear showed up while I was away, so I have everything I need to finish now. It shouldn't be long.

Electrics installed and working.

I believe it is ready to go.
It was hard to find an ESC for a brushed motor, that I forgot Reverse, so I have to pay attention when I launch. Murphy's law !

Rustoleum Premier that I bought at Ace hardware. There is a ton of colors, and it sprays pretty good.
