Well packaged and lots of flat bits of Balsa


And a nice new building board

Cheers
George

Started building it yesterday

Had a spare hour yesterday so I got stuck in and started on the fuselage.
And yes I know it doesn't look much like a fuselage at the moment. It builds in a strange way which you will see as I go along, I guess as it's a strange shape and has many compound curves.

A nice clear plan with the wings full size but the fuselage is less then 1:1


The bits - Lots of good quality wood and lots of moulded bits


The instructions are on an included CD, I printed them out and bound them to keep them together and in good condition


Cheers n beers
George

Build it to fly, don't build to crash!

The build begins with removing light ply and balsa.
A friend of mine came out with a great saying "build it to fly, don't build it to crash" this really sums up my approach to building. You can build lightness in bit it's is very difficult to take weight out.

Some formers before lightning


Same bits after they have been lightened using some Brian Gaskin "softbore" cutters - What a great set of tools for a modern builder




The end result for about an hours worth of building


Cheers n beers
George

2nd session of building

Hi Guys

All fired up and have got a second session under way

The next bit is to add the rear of the fuselage to the front


If you can't work it out, the fus is upside down and the nose is on the right






That's it for the moment, off to the workshop to do a bit more this afternoon

Cheers n beers
George

Very nice george, I take it you'll be bringing it to the basingstoke e-flyin in September?

Does this also mean you'll be carrying the range of RBC kits?

What's your set-up going to be?

Hi Guys

Good to know at least a couple of you are interested in my build

Hi Bill
Welcome to my build thread

Hi Stuart

Yes should hopefully be ready long for the BMAC E-Vent on the 14th of Sept 08. http://www.electric.bmacuk.co.uk/

As to what will power it.... Purple Power of course
As to which model, I'll decide that nearer the time when I will have a better idea of the end weight. RBC says the weight starts at 1,500g, so We'll see if I can build it lighter.
Needless to say it will have more then enough power , the aim is limitless vertical..... well the real plane had 4,200hp, a top speed of 425mph and a climb rate of 4,200ft/min.

Back to the building board.

Cheers n beers
George

No surprises with the choice of motor then .

But does this mean you'll be stocking RBC in the future? I've always wanted the Hawk and this year I might well get it.....

BTW George, that hole making tool seems very handy, I take it in the internal parts we can see with hole's in have been holed by you? I hope your keeping all the peices of wood from the holes, it will be very interesting to see just how much weight you've saved.

Where can I get one? does it just fit into your dremal drill?

Stuart.

Boring Holes

Hi Matt, Welcome to the thread

Hi Stuart

I bought the hole boring tools (Softbore) direct from Brian Gaskin several years ago. Brian attended the Bickley electric fly-in last year so they may have some contact details for him or alternatively Google "Brian Gaskin +Softbore".
They weren't cheap, but have been very useful over the years. They can cut up to around 1/4 of an inch in balsa and 6mm in light ply.
They cut beautifully clean holes unlike any other tool I have tried to cut holes. The shank is too big for a dremel, so I used them either in my bench drill or cordless drill.

A friend built a 72" Lanc and he saved around 30g, doesn't sound much but it's roughly the weight of 2 mini servos.

As you can see from the pic, yes I am collecting the discs, some of my flying buddies think I'm obsessed with saving weight, I weigh everything

Cheers n beers
George

On a cold wet and windy afternoon

Done a bit more this afternoon, now it is starting to look like a fuselage.

It sure is designed in a strange way, I'm sure it could be simplified.
Because it has compound curves on the fus, it need more support for the stringers in my humble opinion.
You will see later that the fus is about 3" linger then the sheet supplied, which makes the very rear of the fus a bit of a dogs dinner as you have to extend the sheeting while it's on the fuselage - Not a good design







Cheers n beers
George
