Please add parameter to exclude failsafe for AUTO

Started this discussion. Last reply by Andrew Tridgell Jun 2, 2013. 1 Reply

For some AUTO missions, failsafe needs to be disabled. When the mission prohibits heading towards home from any point (could hit a mountain) or is expected to fly beyond reliable control range.  Even…Continue

Andre K. replied to Tribal78's discussion Stuttering servo movements/ Phase delay
"HS65 are a bit more prone to electrical noise when fed with 3v3 PWM.  But all HS65 I am using, are used two by two for redundancy, and they were purchased at least 2 years ago, so todays servos may be different. To really compare servo outputs,…"

Andre K. replied to Tribal78's discussion Stuttering servo movements/ Phase delay
"APM2.5 gives 5v PWM. Check you servo bus voltage, if higher than 5.0v  that will increase problems with sensing 3.3v as logic high. To increase the voltage, you can use 2 transistors, or a servo buffer, servo extender or whatever the readymade…"

Andre K. replied to Tribal78's discussion Stuttering servo movements/ Phase delay
"Some servos, like yours, does not handle 3,3v PWM very well. Pixhawk runs a microcontroller that works on that voltage. Get better servos, or amplify the PWM voltage."

"depending on the case, connectors used/open  - you can imagine that under certain flight angle, air will "blow" into bigger connector openings, giving a pressure increase, or the connectors can be on the rear of the airflow, giving a…"

Andre K. replied to agentremnant's discussion Smoking motors
"winding errors in motors can do that, but most commonly it's too high load. The smoke is the enamel insulation of the copper wires and/or epoxy used.  - in any case - too much heat. What motors are you using (brand, model, KV)? , what…"
