Welcome to the forum Wearegoated69. Interesting topic prompt, how to make an air plane with VEXIQ parts. I’m going to assume that you want to make a model, since the combination of weight parts weigh, brain and battery weight along with the light wattage power motors really won’t give you full flight. At best a controlled crash with a glider. You are going to need many dozens of packs of the clear sheets to create a smooth airflow.
A few years ago in 2019 there was a contest to build a Lunar Lander to celebrate the 50th anniversary of the Moon Landing.
It's Lunar Lander Month! Build one and win $50
Read your way through the thread, the builders talk about how they designed and built their kits. All were very impressive builds.
I think I’d go for a Wright Brothers flyer for my first efforts. Combination of 2x beams and the long standoffs to make the wings. I’d use the 4 wide plates to create the front 1/2 of my fuselage, taper to 3*, 2* to get to the tail. Propellers would be next, I own a ton of the flyer round disks, in my head they would be close to the right scale. Pop on some of the small pulley / rubber tire sets and you have the two main wheels and a small tail wheel.
You could also try for a more detailed model using just standoffs for the wings, with 1x20 for the leading and trailing edges. Wrap in the clear sheets. Same thing for the body, pin together some 90 degree and straight standoff connectors to create the frame. (Hey VEXIQ design engineers, I’ve wanted a standoff extender with a 2x pin on the front for awhile. I’ll buy the first dozen bags of 50 when you do a test run)
But you get the general idea. You might want to jump ahead a few years, say to 2028 and build what a personal aircraft could be in 125 years after the Wright flyer from 1903. That would let you use the wings from the space sets and body parts from the construction series from two years ago.
Please post what you come up with. Free building in the off season is a fun way to keep skills up without the pressure of competition.
Good luck!
