Title: "Vivace" as a Harbor Security boaty
Post by: tica on March 17, 2018, 03:08:32 pm: Did an upgrade on a NQD toy last year http://www.modelboatmayhem.co.uk/forum/index.php/topic,59185.0.html (http://www.modelboatmayhem.co.uk/forum/index.php/topic,59185.0.html)
And to be sure that I did have spare parts for that boat, i did get 2 additional jet drives for it.

By chance i came by a FB group called "The Glynn Guest Appreciation Society" and I recalled that I had seen a GG plan where one of these jet drives were used. So I dug into my stock of MB magazines and found the plan for Vivace :}

I will update the jet unit with the same BL motor as the NQD, why ? well because I can %%

And for the first time I'll not use Balsa Cement for the build but UHU Holzleim Wasserfest glue.

Post by: tica on March 24, 2018, 04:06:20 pm: Nose job done, and any holes filled.

I'll be using epoxy and nylon stocking as reinforcement. Dope is a hard to get item in DK and it's smelly.

I'm done with the hull and it ended up with a weight of 144g.

Wrapped it in a nylon stocking and applied some epoxy, it do look nice and know it's just to wait for it to cure.

Post by: tica on March 31, 2018, 10:19:08 am: Some progress over the last days. The boat incl. electronics and battery now weighs in at 562g, GG estimate that the best weight is about 800g.

Hope to get it watertight before April 7th. where we have the monthly day at the indoor pool.

How did it work with the nylon stockings? I used EzeKote instead of epoxy on my latest balsa build, perhaps I'll try it with stockings next time.

Regarding the stocking, it gave me some challenges around the nose and at the back of the access hole, I ended up having to use a small bit of P100 to make it looks nice.

On the stockings front I once had a "X" craft that was made out of blue foam that was covered with a black stocking, using resin and rubbing down between coats I ended up with the best finish I have ever had on a boat.

Post by: tica on April 01, 2018, 05:35:01 pm: Ok gave it 3 coats of Glatfix Porenfüller and 2 coats of sander (primer filler).

The surface is not perfect but good enough for me to continue (I know that I'll be knocking it about), the temperate is still low in Denmark and a snowstorm hit yesterday afternoon = 15cm of snow >>:-(

Next will be a slight rubdown and then some colour.
