Here is the finished balsa plane from the parts posted earlier.

The wingspan is 570mm and it weighs just 200g including battery. It uses a 15g brushless motor powered by a 2S 500mAh LiPo battery. 5g servos are used for rudder, elevator and ailerons.

FANTASTIC !!!!!
From start to finish,
Ill send you some laser ply etc to keep you going.
Thanks Chris
Boat Next????

Many thanks, that would be most appreciated. Boats sound good as we are next to the canal. They'll enjoy falling in.

hi i'm a noobe and have just got a 1290 laser cutter but am struggling to grasp how to draw wing ribs, i have the originals but cannot work out the easiest way to get them on screen and also the fuselage dimensions and angles lol so if their are any 12 year old kids please help
p;s can you guys recommend any books or courses i am based in coulsdon surrey

many thanks mark age 46

Hi Mark

What type of rib are you trying to draw? I've attached a zip file containing a set of ribs for a tapered wing using the Clark YH airfoil. These bits should be cut from 1/16th balsa.

And here are some spars to hold them all together. These are 1/8th balsa.

Here is a DXF for a larger symmetrical airfoil. These will be used in a 40" wingspan 3D plane. 40 engine size.

hi ya many thanks for coming to the rescue i am slowly grasping how to vectorise and outline ribs but there quite a few steps to remember lol
the next step is to get the dimensions of a mini panic fuselage on to pc !

many thanks for your help mark

The box maker link was brilliant, thanks

Do you know of a similar application to produce toothed gears?

Hiya

Once again I'll sing the praises of Boxmaker, very nice piece of kit.

I'll also wave the Inkscape flag, it's a freeware vector drawing package which has many excellent features, not least of which is the price.
Better still on the extensions menu under "render" there's a Gear Function...

Some examples
