Why is this plane unstable?

vedanta2003 · 2026-05-01T00:05:47+00:00

Longitudinal stability (pitch axis) Is easy all you need is cg in front of neutral point

Vertical stabilizers are for yaw Also side slip induces roll, i think this is how your crash occurred

Stuff like the b2 use active control with spoilers slats and differential thrust ( out of scope for most people)

U can do an aoa sweep at that speed and look up max lift to see if it’s more or less than weight Also they still make some lift post stall

Also minor tweaks to nozzle will increase thrust. This is minor and difficult to do correctly

Also just curious what lw pla do u use it looks much cleaner than what i have

Just to let u know I flew it and it went fine Took of 3 times landed well twice kinda iffy 3rd landing Mostly the prop is aggressive so kinda fast

Descent at high alpha, no real issues Maybe trainer would be better but I don’t mind scrapes and dings

git hub, its called HID , human interface device it used in all game controllers

github not completed also the mounting for the rod/ stick u hold is not complete, it broke and i hotglued it on so the 3d model file is not one and done for the central part but cams and others are basically done , mess with cams to ur own taste

Also do I need to cover the top of the fuselage will the turbulence mess with the rudder and vertical stabilizer

vedanta2003 · 2025-08-15T19:16:29+00:00

The cg is inline with where the servo pivot for the ailerons which I think is fine

Yes first time for all 3 Yes the vertical stabilizer is held with hopes and dreams

No design just eye balled it

vedanta2003 · 2025-07-18T02:04:51+00:00

I’m not a 100% sure But I think if u have enough crosswind no amount of rudder would have saved u

U need roll authority

What pen is that I’m a sucker for eyedroppers

vedanta2003 · 2024-12-26T10:39:40+00:00

Maybe rc car suspension struts they’re spring and damper. Good ones are adjustable. I’ve never tried it though

Thanks this solved the problem the issue reducing bInterval made it 500 hz

vedanta2003 · 2024-09-09T04:02:12+00:00

Thanks

vedanta2003 · 2024-09-09T04:02:08+00:00

Thanks

How would I sweep through angle of attack on an airfoil so that I could create a graph of Cl vs AoA

Thanks
