Plane nosediving

Post by Rexbegonia24 »

Hi everyone,
This is my first year building a plane for SciOly and I’m having trouble getting it in trim. I scaled down the dimensions/instructions from this website:

https://www.soinc.org/sites/default/fil ... iad5.0.pdf

by 80% to fit the constraints of Flight. The plane climbs pretty well actually but loses altitude rapidly and ends up nose diving into the ground. Idk how to fix this, I’ve tried adjusting the stab incidence of the wing but that seems to make it worse. I’ve also tried adding ballast to the nose but could explore that more. I was thinking that maybe the wing doesn’t provide enough lift to keep the airplane aloft as motor torque decreases? Also it’s 2 grams underweight soo I have to add weight somewhere. Also the competition is next Saturday. Any suggestions?
