RE: Controlled Crash
What happens when you turn the Transmitter Off when flying a Vtail?
I believe there are two Failsafes you can set. There is one in the Multiwii Program
that activates if it does not hear from the Receiver and you can Rebind the Receiver
with settings for when it cannot contact the Transmitter. How do you set these
Failsafes? Does the Vtail just fall from the Sky if the Transmitter is turned Off?
Thanks Regor
Failsafe features are related to Flight Controllers not the VTail platform itself.
You are right, there are two Failsafe on from the Transmitter/Receiver and the other one from MultiWii.
For the Transmitter / Receiver it depend on the Brand & Model.
In MultiWii, you can setup the failsafe in the config.h
[code]/******** Failsafe settings *******************/
/ Failsafe check pulses on four main control channels CH1-CH4. If the pulse is missing or bellow 985us (on any of these four channels)
the failsafe procedure is initiated. After FAILSAFE_DELAY time from failsafe detection, the level mode is on (if ACC or nunchuk is avaliable),
PITCH, ROLL and YAW is centered and THROTTLE is set to FAILSAFE_THROTTLE value. You must set this value to descending about 1m/s or so
for best results. This value is depended from your configuration, AUW and some other params. Next, after FAILSAFE_OFF_DELAY the copter is disarmed,
and motors is stopped. If RC pulse coming back before reached FAILSAFE_OFF_DELAY time, after the small quard time the RC control is returned to normal. /
//#define FAILSAFE // uncomment to activate the failsafe function
#define FAILSAFE_DELAY 10 // Guard time for failsafe activation after signal lost. 1 step = 0.1sec - 1sec in example
#define FAILSAFE_OFF_DELAY 200 // Time for Landing before motors stop in 0.1sec. 1 step = 0.1sec - 20sec in example
#define FAILSAFE_THROTTLE (MINTHROTTLE + 200) // () Throttle level used for landing - may be relative to MINTHROTTLE - as in this case
#define FAILSAFE_DETECT_TRESHOLD 985[/code]
