Now that the seat has arrived, Alvaro and I have had a chance to try sitting on the aircraft. It's comfortable, but the feel of having the middle propellers so close to our arms is not that good. I think it is necessary to have a nacelle around the propellers, but first we need to be sure we have the right propeller size to produce the required lift. Finding the right propeller will require some experimenting...
Alexander: In addition to the nacelle as mentioned in the post, we have some ideas about other problems that may happen. First, we need a master ON/OFF switch to completely shut off the motors in the event of a flight controller failure (imagine if we lose commands just as the drone is rising ...); Second, we can add an ultrasound sensor, such as those sold for Arduinos, to monitor ground distance by sending this data to the flight controller. This way, code can block the thrust increase if an altitude limit is reached, forcing us to fly low. Third, we will have 12 voltmeters on board to monitor the charge of all battery packs, and we will try to program…
Good to hear that you are taking safety seriously. What will be some other safety features of the drone?
