I finally got my latest project off the back-burner and finished, it's a 3D Printed X-100 Infinity Wing - https://www.3daeroventures.com
It printed without any real trouble, looks great and went together well using medium CA and kicker. It's 100% PLA, although they say it can be printed in LW-PLA for a lighter plane. I've never used LW-PLA, but might give it a try in the future, though I'm concerned it might be more fragile and heat sensitive. Anyone have any experience with it?
I installed a 'E-Flite Power 15' motor with a 12x8 prop, but with a 3S 2200 pack, predicted flight times were literally 2-3 minutes. I took it for a test flight anyway, and found it to be way nose heavy...it took full elevator to barely climb. Since then I've swapped it out for a 'Leopard 3536-7T' (1100) motor, which is lighter than the Power 15, and I added metal gear servos to the back. With those 2 changes, I think the CG should be better, although I could always add a bit to the tail if necessary. I also increased elevator throws by 50%. With a smaller 11x6 prop I'll get slightly less thrust, but it'll increase flight time by a couple minutes. I think it should be OK, the predicted thrust-to-weight is 1.25
