when looking up trim, people often discuss what trim does and how to use it but i haven't been able to find information on what it is Code wise. What is it really?

Hello everyone. long story short, im trying to create my own flight controller for a project and testing has been a pain. im wondering, is there a simulation out there that i can give Arduino code and quad copter specification to see how the quad would generally behave? it would really be a...

I have been having a problem with my motors. when i try to turn them on, i can increase all quad motors to about 30% or so and some of the motors would turn off. im using arduino nano. this is the battery...

long story short, my 4 in 1 esc burned the moment i plugged it in my 2s battery. im guessing that i connected it backwards the first time or something. either way, it seems that only the one part that seems to stop working is the ground and V that goes out for the controller. since im using...

Hello everyone. im creating my own controller and quad-copter code and im using a mpu6050 Chip that Uses an accelerometer and gyroscope to give back The Yaw, Roll and pitch angles in degrees. my problem is Using these angles to set the appropriate motor speed for stable flight since each motor...

So im switching to a smaller build and I tried to control the speed of a tiny DC motor that I happen to own. I used a transistor and it works but there is an issue. The motor speed is much weaker than connecting it directly to the battery. I have a 3.7v battery and if I connect the motor to a...

The quad topples to the same side before it takes off. Now im wondering, why is that? if I'm understanding this correctly, I just need to set all motors to the same power and get the CW and CWW spin correctly. Right now, it seems that all motors are same power but as I increase the power, it...

I have EMAX RS2205 2600KV Brushless Motors and I'm wonder, what blade and Frame would fit these? I looked around for frames but most of the affordable ones says 1200kv motors. As for propellers, I have 10-inch propellers. Is that too large for this motor?

So im building my first quad and after looking around, I have seen some people suggesting that you need a Power distribution board to give each motor even amount of power. Im using a brushless motors and 4 ESCs. One Arduino for controller and one for the drone. Can someone help me out on how to...
