Hi all,

The mag arrived the other day and while keeping an eye on my 2 year old, I had a quick flick through, and he sat on the sofa next too me.

"what you doing?"

"I'm looking at my new magazine"

I then turned to the page with the view of the Vector:

"Want that aeroplane, whoosh!"

The long and short of it is, despite not wanting any more projects this year, it looks like I've got one.

I'm going to use the thread as a way of making and sharing notes and thoughts as I build. Contributions welcome.

Part 1 then - pricing up....

OK, now I have got the little one to bed, The cost will break down into 3 main areas as I see it. I will be able to do a large proportion of the model from stock (I hope!). However in the interests of completeness I will do a complete purchasing list and make a note of anything extra I use, and knock off things I don't. I will warn you all though, this is going to be a very slow build. I need to finish sorting the shed out first.

The components as I see it split into 3 main areas:

Wood

Covering and sundry hardware

Electronics

I'm going to start with the last first, Electronics wise you need the power train, the Rx, a battery and 2 servos.

Power train: I have found the required bits on BRC Hobbies: a 1500kV out runner in the 2812 form, and a matching ESC - rated at 20A. £14.80

The Rx - I'm going to leave this alone as everyone will have personal favorites and need to match the Tx.

Battery - Most Electric Fliers will have batteries in the popular 3S 2200mA configuration, I certainly do; but just in case BRC do a reasonable one here for £9.90

Finally you will need a propeller to suit the motor, the recommended one from the plan is a 7x5, a pusher can be found here at BRC, for £2.75

Nearly Forgot - connectors for the ESC/Motor (£3.95) and for the ESC battery leads(£2.50). again both examples are BRC. You will also want some heat shrink tube, but that is easy enough to find.

Servos - 2 servos are needed for this model, And I wil use some of my stock. If I had to buy however I would be tempted by these at £4.95 each.

NOTE none of the pricing is a recommendation about suitability or the supplier. I am just showing people where I am looking and keeping track for my own purposes, there may be cheaper sources, and you should always assess suitability for yourself, not assume it is right because 'some bloke on-line said so'

Next I'll try and work out what wood is needed.....

Balsa:

I have worked through the plan and come up with a list of wood needed. I think I have covered everything, but if I have missed something, someone will shout out I'm sure.

I'm going to try a table for this one, all prices are from SLEC, all sheets are 3" by 36" and all strips are 36", the others are as noted.

Description Hardness Qty Cost Ea Line Cost
1/4 Sheet Medium 9 £ 1.67 £ 15.03
1/4 sq strip 6 £ 0.32 £ 1.92
1/8 sheet Medium 5 £ 1.25 £ 6.25
1/8 sheet hard 3 £ 1.25 £ 3.75
1/8 liteply small 12" Sq 1 £ 1.09 £ 1.09
1/8 Sq LE 2 £ 0.23 £ 0.46
Nose block 1 1/2" x 36" 1 £ 5.47 £ 5.47
1/16 sheet medium 1 £ 0.95 £ 0.95
Total £ 34.92

same caveats as above apply

Next then, covering and sundries:

Sundry part first:

Control horns - BRC, 5 pack £0.95. only 2 needed but worth having some extras.

Snakes, outers and fixings - Pushrod and 'output' end accessories - BRC £1.75 each, 2 needed, £3.50 total.

'input' end parts - 2mm threaded rod and clevis - £1.50 each, 2 needed, £3 total.

Covering to follow

Covering - BRC - Solar film, £5.95/roll, I think 2 rolls will be the max for this one - £11.90

Solar trim - I think 2 colours will be preferred here, so 2 rolls, at £4.50 a reoll - £9.

Obviously shipping is on top, but I have not worked it out as I probably won't need everything listed - I think I have some 1/4" sq for example.

I have excluded glues, tools, tapes and things used in construction as these will not be single use items.

There will now be an extended pause while I get the shed usable, figure out what I already have and get the missing bits ordered.

Just one comment for today - I am hoping to get myself a 3D printer later on this year, dependant upon funds and getting the shed squared away.

This looks like it might be a nice model to 3D print, in sections. I might just have to have a go at drawing up and seeing how it could be done in the print envelope of the machine I am looking at....

Watching with interest Olly, the magazine needs more designs like this.

Thanks guys, nice to know I'm not alone in my little chamber of insanity!

As I say will be a slow build as need to do some sorting out first. Managed to sell some stuff last night, so first bit done and 3D printer part funded!

If I can sell the rest for what I want for it then the 3D printer will be fully funded.

I'll be tagging along with this thread too, even though my mag hasn't arrived yet. My resolution for this year is to step out of my comfort zone and explore a more diverse range of models to fly.

Subscribed to the thread with interest.

What is the strength of 3D printed parts V's balsa or lite ply and the equivalent weight?

John - Depends on many variables, how you print it, (grain direction in effect) temperature, cooling period, layer thickness, all sorts.

Not even sure on weight. I have been casting my eye around looking for a nice design to try it out on, and while you can purchase pre-done 3D printing plans for Spitfires etc, I really fancied trying something of my own.

I think I will end up making 2 of these at least - one trad-build, and 1 3D print, but they may not be ready at the same time, and as I say a slow burn on both!

I to am taken by this design it appeals to my liking for hi tech composite aircraft , I've got 1 model on the board (Pilates pc6) The Tony Nijuis mossie and 1of my own design to be called Le_B Riot a Bleriot x1 variation ,so I'll be following your build Ollie. Happy building

Hi Olly, Glad to see you're thinking of building a Vector. I'll be interested to see how you get on. If you use the BRC 2812 1500 Kv motor You will need a 6 x 6.5 prop. That was the motor I originally used on the prototype. Remember to pick really hard quarter grain balsa for the 'tailplane', pretty much everything else can be medium light. good luck and happy building.

Forgot to mention - You don't need a specialist pusher prop, just use a standard one, put it on backwards and run the motor in reverse. that way the torque reaction still works to the left as we are used to.

Correction

sorry - In my previous post I recommended a 6 x 6.5 prop for the BRC setup - my mistake, on closer examination it's a 6 x 5.5

Thanks Pete.

Did you draw this up using CAD at all? If so can I be cheeky and ask for a copy of the file to turn it into a 3D printable version? I'm looking at spliting it down into sections that can be 3D printed on most 3D printers and haveing simple 'pin and socket' glue joints where needed.

If not then I'll draw it up, but in the interest of saving time having the base file would be very useful.

This is still going to be a 'slow burn' project, as I need to purchase a 3D printer yet, but would be nice to get somewhere with it.

Obviously I'll not re-sell or use the cad for any commercial purpose, and send you the adapted file back for your control.
