Let’s adjust the analysis to account for the weight difference between the motors and props:

===== - Original Motor/Prop Weight (2807 with 7040 Triblades): - Motors: 56g × 4 = 224g - Props: ~7g × 4 = 28g - Total motor + prop weight: 252g =====
* New Motor/Prop Weight (2515 with 6045 Props): - Motors: 20g × 4 = 80g - Props: ~4g × 4 = 16g - Total motor + prop weight: 96g
* Difference in Weight: - 252g - 96g = 156g saved with the lighter 2515 motors and props.

===== - Original weight of the Mark 4 frame (with FPV gear): 455g =====
* Subtract 156g (weight savings from motors and props): - New frame weight: 455g - 156g = 299g (without battery).
* Battery Weight (2S): - A lightweight 2S battery weighs ~80-150g. - Adding a 100g battery as an example, the total weight becomes: - 299g + 100g = 399g.

===== - Thrust (2S, 2515, 6045 props): - Each motor provides 150-200g of thrust. - Total thrust: 600-800g. =====
* Weight with Battery: - Adjusted weight: 399g.
* Thrust-to-Weight Ratio: - Minimum thrust: 600g / 399g ≈ 1.5:1 (hover capable). - Maximum thrust: 800g / 399g ≈ 2.0:1 (good performance).

===== 1. Hovering: - With a 1.5:1 thrust-to-weight ratio, the drone can now hover comfortably without pushing the motors to their limit. =====
# Flight Performance: - The lighter weight improves overall efficiency and flight time. - A 2:1 thrust-to-weight ratio at maximum thrust provides enough headroom for mild maneuvers and stable flight.
# Wind and Payload Handling: - While it’s not as powerful as the 6S setup, the 2S system should handle light wind and small payloads reasonably well.
# Flight Time: - The reduced weight and lower power draw of the 2515 motors will likely extend flight time compared to the 6S system.

===== By accounting for the weight savings, the 2S setup with 2515 motors and 6045 props is now much more suitable for the Mark 4 drone. The adjusted weight of 399g allows for stable hovering and decent performance, making it a practical setup for lightweight applications and casual flights. While it won’t match the raw power of the 6S setup, it is now an efficient and viable configuration for the frame. =====
