On the earth of FPV drone, there’s a curious mounting type that’s gained consideration: the “rest room tank” battery mounting. This technique includes inserting the battery sideways on the drone, quite than the traditional front-to-back orientation. Let’s talk about its impression on quadcopter dynamics on this article, the advantages and downside of bathroom tank battery mounting.
The Idea of Rest room Tank Mounting
Rest room tank mounting alters the mass distribution of the FPV drone. Think about a cylinder: it rotates simply round one axis however is extra sluggish across the different as a result of mass’s distribution. Equally, when the battery, a major a part of a drone’s mass, is mounted sideways (rest room tank type), it adjustments the drone’s responsiveness. Particularly, it enhances responsiveness on the pitch axis whereas barely lowering it on the roll axis. This trade-off in axis responsiveness is a matter of private choice.
Influence on Quadcopter Dynamics
If you mount the battery in a bathroom tank type, you’re primarily buying and selling responsiveness between the roll and pitch axes. A drone with a front-to-back battery will likely be extra responsive in rolling however much less so in pitching, and vice versa for the bathroom tank type. This distinction in responsiveness stems from how the mass is unfold throughout the drone’s body.
Sensible Benefits
Past the change in flight dynamics, rest room tank mounting presents sensible advantages. For compact racing frames with a brief physique, becoming the battery on high may be difficult. This drawback exacerbates if there’s a GoPro digicam mounted within the entrance, because the battery can press towards and doubtlessly harm it. Mounting the battery sideways addresses this difficulty, permitting for a extra compact body design with out risking harm to the digicam.
Nonetheless, it’s essential to notice that the proximity of the battery to the props might be a priority, relying on the body design. In some circumstances, it’d enhance the chance of prop strikes on the battery.
Tuning and Efficiency
Whereas it’s true that PID (Proportional, Integral, By-product) tuning can compensate for various mass distributions to an extent, it’s extra about how the quadcopter must work tougher to attain the identical price of rotation on sure axes. This necessity may end in completely different PID settings for every orientation. Usually talking, the axis that’s tougher to rotate would require larger PID good points.
Private Desire and Practicality
Finally, whether or not or not rest room tank mounting “flies higher” is subjective. Some pilots may choose the altered mass distribution and its impression on flight traits. Nonetheless, I consider the selection usually boils all the way down to sensible causes like becoming the battery extra comfortably and avoiding harm to different parts.
Conclusion
Rest room tank mounting in FPV drones is greater than only a pattern; it’s a sensible strategy that impacts the drone’s responsiveness and type issue. Whether or not for efficiency, comfort, or necessity, it presents an attention-grabbing different to conventional battery mounting strategies. As with many points of drone flying, it in the end comes down to private choice and the precise necessities of your construct.
