G'day everyone
I have just resurrected a home built quad that I bought off a young fellow a month or so back. It is a home build from Aussie Stuarts build a FPV racing drone for $99. I can't get the little beastie off the ground.
It has the basic components he recommended, but I replaced the F1 board with an F3. Being very new to the quad copter world, I have spent quite a bit of time messing around learning how to set up betaflight and BL heli (massive learning curve). The original software was cleanflight which I have overwritten.
Now to my problem:
I have set up the arming to have the motors idling. When I apply throttle, three motors spin up evenly, but one lags slightly. The result is props hit dirt before I can lift off or hover due to the imbalance. I can get the drone to a point where three motors are off the ground, but one still lags tilting the craft. I have tried to take off using a bit of pitch and roll compensation, but it just over corrects and props hit ground once again. I have also tried rapid throttle increase which just cartwheels the drone.
I have held the drone on the ground and fired up the engines then checked changes in motor speeds when applying pitch, roll and yaw. To my inexperienced eye, they all seem to alter speeds in relation to my applying the different stick controls.
Can someone offer me some direction in how I may adjust the engines speed so they are all synchronized and power up evenly please?
Cheers
