mini-drive (1)

...here we have a preliminary stage of a - yes, beginning development! the problem: we have our plans for the new farms https://grabcad.com/library/farm-for-pangasius-and-ducks-1 and there we have bees to pollinate the trees used in the farms. https://grabcad.com/library/single-stage-with-21-honeycombs-1 https://grabcad.com/library/beehives-robot-1 we need to monitor pollination by bees, the development of flower formation and fruit formation, also to monitor the bees, even the smallest drones, because you cannot and may not enter the new farms. the problem here is: you can buy mini-drones today - but no mini-drones that - yes, sluggishly and sluggishly fly like a fat (lazy) bumblebee! So we're trying to construct a sluggish flapper man here - and what's special: they should act autonomously! several! so there is nobody who unfolds the rotor arms - turns on the drones and lets them fly: we need automatic drones that do everything themselves - with swarm intelligence! i.e. self-loading, self-acting mini-drones that transmit images to the master computer - otherwise endlessly take care of themselves - around the clock! You can't buy something like that today! so we have to do it ourselves! In the first stage - I want to try - to bring the required 6 rotor arms into a state where the rotor blades are placed on the body like a bird - all rotors on top of each other when they are at rest. and i want to make the rotor arms small by means of telescopic guides, as small as possible, i.e. when at rest, place the rotors tightly on the mini-drone body. if you have a mini motor with a diameter of 7 mm as a default - so don't necessarily want to build a smaller one yourself, which is feasible : that's the initial requirement that determines everything else. in the first part here- i tried to develop a complete rotor-arm- and also stopped using brass bearings: we want to make everything out of high-performance plastic- robust, flexible and also durable! if you suddenly want to an
