The 3D printing has been going very well. Have now nearly finished two more planes since my last post.
One is called the Graywing from Eclipson planes (https://www.eclipson-airplanes.com/egw-80). Was going to print this one with LW PLA, but had trouble getting nice prints for the fuse sections. So went with regular PLA+ instead (including silk PLA+ for the winglets, canopy and elevons)….but used a thinner wall width which really helped bring the weight down. Using a light weight quad motor, the AUW is about 625g. I’m pleased with this, as the published AUW using PLA is given as 750g (using a heavier plane style motor).
The other plane is the Caracara (https://www.thingiverse.com/thing:4273142). This is a free design on Thingiverse. It’s a pitcheron glider, with a slight hybrid approach, as the V-tail is made from balsa. If you not familiar with this type of plane, instead of movable control surfaces as part of fixed wings, the whole wings move (pivot) around a central axis, and the tail section is fixed with no control surfaces.
I’m quite excited to maiden this one, as I haven’t had a pitcheron plane before. It has a wingspan of 94cm and AUW of 255g.
If anyone has experience with this type of plane, I’d really welcome any advice on setting-up and/or flying a plane like this.
Looking forward to seeing the Greywing fly – it looks like is gone hypersonic just sitting there
Well done Jeremy
Very impressive Jeremy. I have to say I was ignorant about the terms Wingeron and Pitcheron, so I looked them up and am including a definition I found.
Wingeron: The wings pivot only for roll control. The airplane has a separate elevator and elevator servo.
Pitcheron: The wings pivot for both pitch and roll control (they can act together or opposite). This uses a separate servo for each wing, and some sort of mixing. The horizontal stabilizer has no movable elevator.
Thanks Trevor. They’re good defintions for wingerons and pitcherons.
Hi Jeremy a superb looking aircraft well done but you forgot to put the rubber bumper on The pointy end ( 👷♂️🤕 just kidding) good luck with the maiden
Thanks Clem…..yeah hopefully the pointy end stays in the air where it’s meant to be. But a nose dive will certainly make a good lawn dart!
Hi Jeremy, they look pretty cool, I’m looking forward to seeing them fly. The Caracara looks pretty interesting and the pitcheron approach sounds very different. I would imagine that roll and pitch control would be pretty sensitive.
