The 2S setup with 2515 motors and 6045 props will be able to hover a 455g Mark 4 drone (without battery) under ideal conditions but will do so with difficulty and limited performance. Let’s analyze why hovering will be challenging:

===== - Thrust per Motor: With 2S power, 2515 motors with 6045 props produce 150-200g of thrust per motor at full throttle. - Total maximum thrust: 600-800g. =====
* Total Weight: - Base weight (drone without battery): 455g. - Adding a lightweight 2S battery (~80-150g): 535-605g total weight.
* Thrust-to-Weight Ratio: - At 535g weight with 600g total thrust, the thrust-to-weight ratio is 1.12:1. - At 605g weight with 800g total thrust, the ratio improves to 1.32:1.

For stable hovering, a thrust-to-weight ratio of 1.5:1 or higher is recommended. Ratios near 1.1:1 or 1.3:1 mean the motors will operate near maximum throttle just to maintain hover.

===== 1. Throttling Near Max: - Operating near maximum throttle increases motor stress, reducing efficiency and potentially causing overheating. =====
# Instability in Flight: - Any additional weight (slight payload, heavier battery) or environmental factors (wind) will disrupt the hover. - The lack of thrust headroom means the drone cannot quickly recover from disturbances.
# Shorter Flight Times: - Running at high throttle consumes more current, leading to shorter battery life.
# Reduced Maneuverability: - Without sufficient thrust overhead, the drone will respond slowly to inputs, making precise control and adjustments during hover difficult.

===== - Can it hover? Yes, but it will hover barely and inefficiently. The drone might feel sluggish and could struggle with stability in less-than-perfect conditions. =====
* How practical is hovering? - If hovering is your only goal, it may work for very short flights in calm environments. - However, this setup is not practical for dynamic or prolonged flights, as the motors are underpowered for the weight.

===== 1. Reduce Weight: - Use the lightest possible battery and components. Avoid adding any unnecessary gear. =====
# Increase Power: - Upgrade to a 3S or 4S battery (if the ESCs and motors are rated for higher voltage). This would significantly increase RPM and thrust, improving hover and flight performance.
# Consider Larger Props: - Switching to larger, more efficient props (if the frame allows) can improve lift without changing voltage. For example, 7045 or 7050 props might help.

===== The 2S setup will hover the 455g Mark 4 drone, but it will be underpowered, inefficient, and impractical for anything beyond brief, low-demand flights. Upgrading voltage, reducing weight, or using more powerful motors are better solutions for reliable hovering and improved performance. =====
