Alexander Malikov commented on Krzysztof Bosak's blog post Servo precision - finding low current draw, low/any speed, <<>> standard or mini servo.
"Not answer to your question, but just my experience.
Every servo with potentiometer as feedback will lose its precision (or will become jerking) near center position, because of degradation of potentiometer (in the condition of vibrations will…"

Alexander Malikov commented on Mike's blog post Quest for the perfect flight path...
"You can start from k1 = 0.3 and k2 = 3. Roll limit = 30°. Xte limit = 500m."

Alexander Malikov commented on Mike's blog post Quest for the perfect flight path...
"You should think about throwing heading loop out. Best result gives navigation loop over roll loop. Navigation loop is roll_setpoint = xte * k1 + dxte * k2, where "xte" is crosstrack error (should be limited to avoid circling far from path), "dxte"…"

Alexander Malikov commented on Curt Olson's blog post Stability Augmentation System
"Hi Curt, I implemented the same system (also wonder what term to use) and did some tests in flightgear and in the air, but not takeoff/landing. When the pilot centers roll/pitch stick, the autopilot holds current pitch and slowly decrements roll to…"

"The HUD shows actual values of roll/pitch/etc from the property tree. Maybe it is an effect of outside view."

Alexander Malikov commented on Chris Anderson's blog post T3--Round 6: The Simulation Round!
"Brian,
I experienced this problem with FG2.0 and rolled back to FG1.9.1. FG2.0 doesn't wait for new values, it just hangs if you don't send enough data. So I use FG 1.9.1 because its UDP queue lag is known and avoidable."

Alexander Malikov commented on Chris Anderson's blog post T3--Round 6: The Simulation Round!
"Brian,
I fought with latency in the begining of FG use. And I found that rising FG input frequency doesn't solve the problem completely. So I decided to add a variable to FG property tree and use it as a packet number.

FGWrapper does the following:…"

"It is not an open source project. On autopilot board there are 5 serial ports (for sensors, modem and servos), FRAM (config etc), SD card slot (log). Used software: FreeRTOS, Chan FatFS (for SD).

FG really helps much in debuging/tuning!"
