Decided it was time for a new plane for the summer and I saw some interesting designs from 3DLabPrint (
www.3dlabprint.com), including a P-38. 55" wingspan, flaps, retracts, etc. (12 servos in all).
Basic principle is that you purchase the model files and send them one after another to a 3D printer. Once they have been printed you glue them together with CA and add the electronics. Biggest one is a 75" Corsair, and the 67" Spitfire looks really nice.
The structures are very complex - quite amazing to look at.
Printing takes a while. The job I started this evening has the parts for the left wing outboard of the left engine/fuselage and is estimated at 11 hours (will probably be a couple of hours more than that). You can see what I have made so far. My printer is a bit bigger than what they design for so I am now starting to combine pieces (the current job will be in two pieces while the right wing equivalent was four pieces.) I will probably reprint the right wing if the left one works well (time to order more filament).
Don't hold your breath to see it at the field...
