Amati Riva Aquarama build log
« on: July 07, 2019, 02:25:23 PM »

Hi,


I am new to the group and to RC boat modelling but have done a few static models and RC planes.  Having looked at a number of build logs I decided upon the Amati Riva kit as it just looks soooo cool.

I'm a little dubious about posting this after reading ukmike's log.  If my Riva ends up anything like his I'll be more that chuffed for sure.


Anyway here is the kit as received from Hobbies in Norwich.

You now also receive a four page glossy covering changes to the main instructions





These parts seem a little different.  It all needs painting and the 'fake' stitching seems to be a thing of the past.  Like ukmike I'd really like to improve on this part however talent (or lack of) might prove to be my undoing





Unlike others I've opted for the Amati supplied motorising kit.  This is because everything else I've built used a good old internal combustion engine and I'm still getting to grips with all this electrickery stuff. I did ask the suppler for details of what was included but they were understandably unwilling to break into the box so for others I've included some details. 

However as the ESC could be bought for about 25 Quid and the motors for less than 4 quid each, then at 150 for the hardware kit I think I've chosen a very expensive option.  Ho Hum!

That looks like a very detail and quality kit. I look forward to watching it come together.

What do you mean 1:1 is not a model?

Before starting in earnest I've been putting together the Hobbyzone Slipway to keep everything nice n square.  Although it undoubtedly does the business I'm not as impressed as I thought I would be.  In particular there are two cramps that hold the stem and stern that need very careful packing between the inside of the cramp and the boat keel before tightening as there is no adjustment for keel thickness whatsoever.  If you rely on the flex in the wooden cramp to do the job it just snaps in two.  I found this out the hard way of course.


It also took ages to get the Riva's keel installed in the slipway.  I kinda expected everything would pretty much automatically centre and align but not so, more a case of close but not close enough without a fair amount of jiggery pokery.


Anyway that's todays gripe out of the way.  Here it is installed with the very first frame in place.  Don't they have a ceremony when the keel gets laid down on a ship?  That's my excuse for a beer anyway...

Don't think I've ever seen one of those slipways used before, it'll be interesting to see how you get on with it.

Almost finished the frames now.  Quite a slow process as each has to cure before the slipway is repositioned for the next frame and as I'm using Titebond 3 it takes a while to dry. 


The slipway is doing a good job of keeping everything square but sadly I've found another problem with it.  Both the face of the 'square' that holds the frames vertical and at 90 degrees to the keel and the baseboard is melamine coated, presumably to resist glue sticking the boat frame to the square as it dries.  Unfortunately it does not do much of a job of preventing these parts from gluing themselves together and is so microscopically applied that it rips away from the MDF of the slipway as you try to release the square.  (See picture below).


Anyway I am pleased with how it's all going together.  The laser cut pieces are absolutely precise and fit together beautifully.

Apologies for skipping a few steps, Here's where I am now.  Frames all finished and the ribs added to the stern and reinforcement to the bow.


I guess that the point of the reinforcement is to add some wood to the frames upon which the planking can get a firm grip but it feels like I'm building a boat to compete in Robot Wars.  This thing is gonna been indestructable!

Thanks Taranis, the slipway certainly helped with this and the accuracy of the kit parts makes it doubly easy.


I've now got the cabin floors and the foredeck bulwarks in place and it's beginning to take shape.  The next stage after fitting some rear reinforcement will be the first of the mahogany parts making up the interior of the overnight cabin.


With regard to sealing the mahogany what do you guy's think I should use?  I've seen a number of solutions posted within the group from a full on resin coat (with and without glass reinforcement), to specialist varnishes.  I had in mind to french polish all the mahogany (including the hull) as it should both look stunning and the shellac should make it completely waterproof.  Whilst I know it won't be as durable as a resin coat, if treated with care I would have thought it would do a good job.


Any advice gratefully received....
