We'd love to hear from you if the print was successful.

This little thing has a wingspan about 616mm, and weights complete with RC-electronics and battery for receiver less than 300 gr. The wings are stabilized with a wooden beam of 5mm round-material, or a carbon-round stick or tube of this diameter. It is stared by two servos inside the wings, using a wing-mixer programmed in your transmitter.
Update 1 (10/09/2017) : New canopy with 2 3mm-holes to put a wood beam and use rubber bands to fix the canopy. Have a look at picture how to fix the canopy with rubber bands. You can put these rubber bands into the inside, if you like.
Update 2 (10/10/2017) : Added winglets to get better stability during flight. Use more "normal" slice-parameters for these parts, i used 3 loops and 25% infill.
These winglets snap into the left and right wing, but it is better to glue them.
Next update is in progress, a new fuselage to add a motor and battery for powered plane.
Materials and methods
Used PLA to print this, used KISSlicer, ask for the settings if you like
Issues are used to track todos, bugs or requests. To get started, you could create an issue.
The COG (Center of Gravity) was calculated to be something about 8.6mm from Wing-Front, but that is to low, it can be some mm farer away, so you don't need so much lead in the nose :)
I have "flown" this thing yesterday, only an small amount of throws on a meadow, and it shows that it will perform good on aq ridge with an good amount of wind...
A guy on an other page asked what Slicer is was using, he used CURA and could not slice it right. If you want to use CURA, you need to make more parameters visible to slice these small walls. Its a parameter named something like "print thin walls" (is use the german version), you need to make this parameter visible and activate it, then the wing is sliced well.
I have used Slic3r in the past, but i am not able to test it, cause an update has made it non working, i will keep you informed about parameters for Slic3r, too, when there are new updates that make it working again.
