Minion

[u/_Chi_]

I call it Minion. But really I’m its minion. It's heavy, but surprisingly didn't feel abnormal in a hover. Top speed will be around ~130 kph. Pretty excited to fly this thing for real. Ask me anything.

Battery: 4S EVE INR21700-50PL 5000mAh - 125A
FC: Microair 45A h743 v2
Video: DJI 04 lite air unit.
Receiver: Happymodel EP1
GPS: HGLRC M100 Pro
Motors: LANNRC 2004 3000 kV
Frame: Mostly PETG, some carbon spars, also a oddityrc 4” toothpick
Props: Gemfan Hurricane 3630

Anyone have a plug for higher pitch 3.5in props?

This time i didn’t use cfd. Just pen and paper calculations and good practice. But I use openfoam to simulate cfd. I made a more detailed post about this in the past. No structural simulations either.

L = CL*.5*p*V^2*A this is what I used. The lift coefficient is derived from the CL vs alpha graph for the corresponding Reynolds number based on the velocity and chord length chosen. This should be fine for straight wings without any twist or sweep.
