Hello Folks !

Sailboats are my second largest passion righ now (the largest being helis) and because i wanted to build somethign on a small budget while here in Doha, i decided to build a model of a model Smiley

The choice fell on a Razor 3 Footy yacht (for more information on the Footy yacht class look here: http://footy.rcsailing.net/ there is also plans) that i intended to build even smaller (most people consider footys teh smallest practical size of rc sailboats).
I wanted to do exactly 1/2 scale but printing out the templates i got only 55% scale so it`s a tad larger than i initially planned but oh well i am rather happy by now i got it slightly larger.

the specs:
Length overall 180mm (7in)
beam 56mm (2,2 in)
Displacement 75g (2,65oz) and the ballast weight minimum 35g scaled from the original model.

The Hull was made in about 1 hour and is of 0,6mm ply in tape and glue construction. very light no internal formers  the Keel will slots into the a plate that holds the RC. The RC installation is a rather large Spektrum AR6100, 2 x e-sky 4g micro servos and a LOSI micro car 150mAh battery for receiver pack.

it uses the plan suggested swing rig (mcrig), built from some piano wire (thanks Anwar!) skewers from carefour and a pice of carbon rod leftover from a wrecked parkzone vapor. A shopping bag serves as sail material Smiley

so far i could only sail it in the compound pool, with very turbulent winds, but it is working well Smiley

And yes, you have inspired me enough and more to build one soon Smiley

It is fun to see the shadows of the waves at the bottom of the pool !

At the risk of not hiding my admiration for your "build" work, I took the liberty of posting a thread about you in the RC India forum, which is much more active than the Qatar one (we have a big population, and proportionate number of RC enthusiasts!).

http://www.rcindia.org/rc-people/philip-from-austria-czech-republic/

And your work has already inspired more people !

If my build is motivating people to build one themselves i`m very happy Smiley But to be truthful there realy isn`t much to it.. i just build from a plan someone else designed and perfected so hats off to the great guys who design models for us and let us have their plans. And boat building wise i stand on the shoulder of giants.. like for example Brooks Martin a friend i have unfortunately never met face to face but a great friend, motivator and mentor nevertheless !

have a look at his boats here:
Aldebaran Tops'l Schooner http://www.rcgroups.com/forums/showthread.php?t=1096365
The Bottle Baltimor Clipper http://www.rcgroups.com/forums/showthread.php?t=1071509  This build made me start building boats Cheesy

i`d greatly enjoy if you get into sailing Footies Anwar, it`s about the best starter into boats there is as the very credo of the class is to be easy to build, with pretty much any material you can find, cheap and incomplicated Smiley They are also very very fun to sail especially in larger groups. The sailing can be learned in a few minutes of practice too. So who knows maybe soon there will be a footy fleet in India and Qatar ! Smiley

had another nice sailign session at the pool today Smiley a bit too windy in teh gusts, for this a smaller B or even C-sail rig would be required. but nevertheless good fun Smiley

i tried anwar.. but teh wind was just too strong yesterday at teh beach. the sail sheet toreloose and the sail came loose too so i had to wade in and retrieve her before she would get swamped and sink Wink same is true for yesterday as today... some more piano wire, 2 pieces of skewers and a old shopping bag and one could make another smaller sail realy easily Smiley
