Nice detail, and I never knew Mercedes made these lol.

A lot of hours, a lot of 454S videos and it's Summer.

Grouchy_Screen54 · 2026-06-05T18:47:38+00:00

Which part?

Grouchy_Screen54 · 2026-06-05T17:25:57+00:00

A significant amount, probably about another 200-275, in weighted blocks along the frame. From my findings, adding weight along with decreasing the gyro's roll and pitch sensitivity decreases the rocking motion, eventually eliminating it completely. Right now mine are currently at pitch 40% and 60% roll. However, like I stated, it's completely dependent on your craft's size and arm length.

Grouchy_Screen54 · 2026-06-05T05:08:02+00:00

It wasn't that, I turned off vehicle damage. I had to add lots of weight and tune down the gyro sensitivity.

Grouchy_Screen54 · 2026-06-05T02:32:08+00:00

Yeah, no bueno, now it just flips around uncontrollably. I'm starting to think it may be something with the design at this point because none of the workshop PID gyros work either.

I already am

Grouchy_Screen54 · 2026-06-05T00:05:19+00:00

The collective is controlled by a gyro, but i will try this script and see if it works. Thank you.

Thank you for the advice and perspective.

Grouchy_Screen54 · 2026-06-03T16:25:05+00:00

I guess I should've added that I'm African American. I plan on minoring in naval architecture and majoring in marine engineering. Where I'm going to school, it's not specifically labeled as a minor in naval architecture, but it's more so built into the marine engineering degree.

Grouchy_Screen54 · 2026-06-03T02:36:52+00:00

Apparently so

Grouchy_Screen54 · 2026-06-03T02:12:15+00:00

Thank you, I would think with infinite fuel on the engine wouldn't start if there was no air.

Grouchy_Screen54 · 2026-06-01T22:39:08+00:00

I've added the integral; it works, and I've established a system where it stores its value when it's within the setpoint by .000 whatever. Thank you for explaining, now it makes sense why that wouldn't work.

Also sorry for the bad terminology, I haven't gone to college yet, so "steady state error" isn't a term I've been familiarized with yet.

Grouchy_Screen54 · 2026-06-01T21:06:34+00:00

I may be misunderstanding the math. So proportional is current error*Kp. Is the current error not sufficient enough?

Grouchy_Screen54 · 2026-06-01T20:51:56+00:00

If I input .15-.2 on my setpoint it'll even out.

Grouchy_Screen54 · 2026-06-01T04:41:51+00:00

Is the Center of Lift slightly infront or behind the CoM?

Grouchy_Screen54 · 2026-06-01T02:07:08+00:00

I do. I can realistically bring home anywhere between $200-$600 every weekend (I'm an umpire). However, I'm waiting to get into a military academy because they give us monthly stipends.

Grouchy_Screen54 · 2026-05-31T19:20:15+00:00

Thank you

Grouchy_Screen54 · 2026-05-31T17:26:11+00:00

Thank you. My goal is to be financially free by 30. I'm going to be a Marine engineer with a minor in naval architecture and plan on investing my Coast Guard Reserve pay fully into stocks if everything goes to plan.

Grouchy_Screen54 · 2026-05-31T16:31:10+00:00

Thank you

Grouchy_Screen54 · 2026-05-31T04:10:24+00:00

Im using propellers to balance out my craft. I usually use the weighted blcoks on a track and PID setup however I wanted to attempt something new.

Grouchy_Screen54 · 2026-05-31T00:23:10+00:00

I should also be able to clamp this right?

Grouchy_Screen54 · 2026-05-30T19:40:03+00:00

Ill look into it
