This is a micro scale RC airplane designed to essentially snap together from common hobby store supplies. It can be assembled with the aid of a little superglue reinforcement in under 20 min post printing.

Printed using Tough Resin on a Form 1, I'm fondly calling her the 'Air-Form 1.'

It took 3 design iterations but this final version is a superb flyer. weighing roughly 60 grams, she is a micro plane but the dihedral wing make her very stable even in a couple kts of breeze.

The motor mount/gearbox, wing clamp, and both the rudder and elevator hinges and clips were all printed out with tough resin. The main body is a rectangular carbon fiber rod and the wings are 2 rectangular balsa sheets. The motor and gearing is a replacement motor/geartrain for a laTrax quadcopter. The receiver is a specktrum ar6410

battery: 150mAh
thrust: 54g
weight: 60g
wingspan: 58cm
dihedral: 15deg
flight time: 11min

Non-Printed Parts:
specktrum ar6410
150mAh battery
laTrax motor
laTrax bearings
laTrax gear/propshaft
laTrax prop
3/32in X 7/32in X 3ft rectangular carbon rod
3/16in carbon tube
7/64 carbon rod

I'm hoping to add landing gear in the future!

Watch the scale! Dimensions are all in mm but you may need to scale the parts 10X if they appear too small. For reference, the squared dimensions of the motor mount part should be about 10.5x15x26mm

Do you have the size for the wings and tail?

Now I see why there are no makes. Can't find the 3/32in X 7/32in X 3ft rectangular carbon rod. Maybe you can post the cad files so it can be changed to fit materials that I can find online.

Looks like a really great design.

Do you have the size for the wings and tail?

How stable is it outside?

Have you tried it outside of the gym?

10X should do it - it is in the 'thing details' somewhere

What scale do we use to get the proper size. There all tiny??

What kind of battery - 150 mah doesn't cut it.
I am new to this kind of thing and want something small to start off with.
Cool plane by the way.


Where are those cool STLs? :D
