Another 249gm, but 50 minutes flight time Bi-copter
meanwhile i will stay with quadcopter structure. I have less confidence with the bi-copter structure. That bi-copter is geared tilting rotor, meaning:
- yaw movement could be less smooth than quadcopter. quad uses diagonally opposite props to perform yaw movement and faster, more accurate response.
- structure of 2-prop with suspended body might make the drone's body keep swinging like seesaw under windy condition. 4-prop should has less of that swinging problem.
- at 250g, 7-8" prop, 50min flight time, it could be worse than 4.7" prop mavic mini in handling wind. Might not be good for windy s'pore as could crash easily.
- tilt rotor has slower response. locking to GPS might be ended like hubsan drones. Meaning circle, oscillating, sway, swing around a GPS position than locking steadily to that position. For a mavic it will hover steadily in the air, with that GPS fixed point.
- Drone likely not useful for low altitude filming or selfies which is important for tours. Only good for high altitude scenery filming.
i will skip this. Unless there are excellent feedback from youtube reviewers, and price closer to mavic mini.
other more technical evaluation got to wait for our expert hwzlite's comments liow..
