Re: Altitude Hold improvement solution

I have a gy-80 chinese IMU, with an ADXL345. Oops. the default value is 265, changed to 278(was in doubt between 278 and 280) So, i have now checked out the r1155, had to recalibrate, and now the sensor actually reads 265. I re-uploaded the version where i had this problem, and after calibration it ...

Re: Altitude Hold improvement solution

Hey guys, I had a problem that whenever i activated the alt hold, the copter would drop. so, debugging, i found my accelerometer was measuring 1g as 180, and the sensor's acc_1g was defined as 165. so whenever the copter was standing still, the algorithm thought it was rising! i changed the sensor a...

Re: Tricopter servo interfering with ppm signal

But how does that happen? I mean, the servo is powered alone by an esc's bec. Can the interference travel through the battery wires? Is it possible that my aluminum frame has something to do with it? In a few hours i'll test with a different servo, and see if it gets better, probably make a video to...

Tricopter servo interfering with ppm signal

Hello, folks. I have been using multiwii for some time now. It was working perfectly on a quadcopter, but now i'm trying to build a tricopter, and i'm having weird issues... when the servo is under heavy load, the ppm signals on the receiver gets all messed up! they just start jumping around. as soo...
