    3d lab print F4U

    Just finished this and attempted to maiden this past weekend. This is a petg print, I had an elevator issue i fixed today so she is 100% ready now. Hopefully we get the weather to fly her this weekend. Click image for larger version

    RM, I have these files, too, but like all things "hobby" there are only some many hours in my day. Did you incorporate the 'folding wings'? And did you add the P&W 2800? I plan on printing the P&W to add to my Flightline F-4u. Looking forward to your 'check flight' debrief. Best, Steve

      Yes I got the folding wings, but didn't print the P&W. I think I might do it after the test flight though if everything goes well. Click image for larger version

          Your Corsair is a major accomplishment for a 3DP plane! What size is your F-35?

                  It looks quick just sitting there. When is the maiden? I assume there are wing spars in there somewhere?

                      Hey thanks, but no I dont have a spar, as much as I would have liked to have a 6mm tube. Hopefully its light enough it won't be needed. I'm hoping this weekend to fly it; the fan is expected Friday.

                        Wind looks right for a test flight of both planes tomorrow morning!

                          It looks like the wings plug into the fuse and are glued in. With the short wing span no spar should be needed.
                          I Printed their P-38 and the wings on that went into the fuse and snapped in.
                          The 3D Labprint guys did their homework on these models.
                          I had printed several but with PLA . The planes are just too brittle and warp easily in the heat.

                            Tom, Have you printed 3DLabs designs in any other material? I thought I'd retry their F-86 again in PETG. The PLA print I did is great with only 1 or 2 flaws per large print with .4mm nozzle. I thought I might try PETG with the .3mm but the times will be looooooooooooonger. Best, Steve

                              Steve, I've only printed their planes in PLA. I had printed 3 of the Stearmsn, The Stearman was a PITA to balance as it was severely tail heavy. The first cessna the motor came off mid flight (the firewall let loose from the cowl). Maybe poor layer adhesion?
                              The second Cessna the wing was in my van and the GA heat made it into a U since it was hanging from bungees.
                              The P-38 was a nightmare with the wing attachment and getting all those servos and control surfaces to work correctly.
                              I may try PETG (flexible) but hoping they come up with a filament just for printed planes.
                              I did have success with their Edge 540 but the gear would break on a not too perfect landing. PLA being so brittle.
                              I've thought of printing some parts of the Edge and Cessna in PETG and the rest in PLA. Sort of a hybrid, Lol

                              Did the maiden today, she was smooth and fast, wings are bolted in but I think I might glue them in though. Second flight was great too. Was very exciting. Like many edf hand launches you have to give it a good toss. Anyway all in all extremely happy. Still didn't get to fly the corsair. it rained all morning and it's a pain to put together and take down. Hopefully next weekend.
                              here's the website for the "F35" if anyone wants a go at it

                                As for the corsair it is totally in petg. I had to reinforce the tail under the horizontal stabilizer with a carbon fiber plate. That helped stiffen it up nicely, and honestly was my biggest concern with the flexibility. I also printed the f86 wing in petg and it was nice all around. I did have a problem though, the gear broke though it on a poor landing when the battery died and I couldn't get them retracted soon enough. It was esun petg and it seemed stiffer than the brand I used for the corsair. Looking forward to seeing what happens with this corsair now.

                                    Also on my sons Cessna, I ended up using a carbon fiber plate on the firewall for mounting the motor. It seem to really help keep the plane together.
