#1. Need BOOST mode fully operational. (Feed scaled internal THROTTLE signal to an output as a PWM signal). #2. Need internal THROTTLE signal “disconnected” from output servo pins and replaced by a user-selectable fixed variable.
Not sure exactly what you mean for number 2, you can set the servo output to rc passthrough or just set the min and max to the same value then it will just be a fixed throttle once armed. Do you mean to be able to ‘lock’ the throttle in flight?
I can’t get boost to work on 3.6RC10 when set for a quad X. As I mentioned, I can set SERVO5 output to option ‘81’ and it works - until I reboot the FC. Then SERVO5 has no output until I set SERVO5 to something OTHER than ‘81’ and then set it back to ‘81’. It then works until I reboot. Currently, the internal throttle signal is mixed with the balance information and sent out the servos. I say “internal throttle” because in many modes (AUTO,ALT HOLD, POS HOLD etc) the throttle signal is generated internally, while in STAB mode, it comes from the user. I want that internal throttle signal to be fed out SERVO5, but not sent on to SERVO1-4. Instead, I want a fixed value to be used in place of the throttle signal for those servos. So SERVO5 will output a signal of 1000-2000 uSec pulses depending on the internal throttle, but SERVO1-4 will output a fixed value (say 1500uSec +/- the balance signals). Charles Linquist
Not sure about the boost stuff, are have you tested both chibiOS and nuttx? and i guess a different flight controller too, changing it to a different output may also change something.
I think i understand what you mean. The ‘stabilization’ motors would be fixed at a average throttle of 50% such that they have maximum available control power. The throttle would therefor only effect the boost motor?
I think i could do that, although I would have to have a read through the code to be sure, no idea about the boost stuff tho
I would recommend getting something cheap to play with first, 1500 miles is a long way, its guna need to be a big plane. 3 or 4m wingspan at least i should think. Depends on what your payload its going to be. Where are you planing to do it? There will be loads of red tape.
I want to film the coastline from Ecuador to Chile, is about 1500 miles, nonstop. First of all, know is possible, but what is the best option? Gas, solar or hybrid? The payload out of gas if I were to use gas is around 2.5 kg.
Quite interesting, I think I have some bit of knowledge on it, but unfortunately there is no dm button to contact you. I have also developed the idea and share it as essay with outline example that helps in practicing much on it.
