I didn't see a better place to put this question, if there is one, let me know.
Because of the quarantine, I am avoiding any non-essential shopping trips, which means I don't have access to foam board (nor got any radio equipment yet). So I am trying out various wing/body/etc designs with what materials I have on hand which is Card stock, 3D printer w/ PLA, 1/2" thick pink foam insulation, Grafix Medium Weight Chipboard, BBQ sticks, printer paper, various glues and various crafting supplies. - But no foam board
For various reasons, my goal is to keep my plan mass under 250g, so I have been weighting the resulting tests with the goal of being able to add 100-120g worth of electronics/battery's/etc (been adding about 100g dead weigh for throw tests).
I am curious, is foam board the hands down best build choice for the low weight builds? If there is something different, I would be interested in hearing about it.
I posted a few photos of my first chuck glider that I basically carved the wing out of the pink foam in my "hello" post here: https://forum.flitetest.com/index.php?threads/hello.62906/
I just got done trying 3D printing ribs and using BBQ sticks and then covered it with printer paper, to see if I could come up with anything lighter - however the full plan only came up a few grams lighter, but I am sure that came out of not using the chip board for the tail surfaces and using a single width of foam for the fuselage instead of 2. (this one does fly ok, but the dihedral could be slightly stronger)
This method also looks like it would be much harder to add ailerons/flaps to then a solid foam wing.
Has anyone done any testing of various wing construction methods? IE is there any value in continuing to try out different wing construction methods? Would be curious on any other testing/etc that has been done here.
