On this planet of FPV drone, there’s a curious mounting type that’s gained consideration: the “bathroom tank” battery mounting. This methodology includes putting the battery sideways on the drone, moderately than the traditional front-to-back orientation. Let’s talk about its influence on quadcopter dynamics on this article, the advantages and disadvantage of bathroom tank battery mounting.
The Idea of Bathroom Tank Mounting
Bathroom 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 big a part of a drone’s mass, is mounted sideways (bathroom 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 non-public desire.
Influence on Quadcopter Dynamics
Once you mount the battery in a rest room tank type, you’re basically buying and selling responsiveness between the roll and pitch axes. A drone with a front-to-back battery shall 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, bathroom tank mounting presents sensible advantages. For compact racing frames with a brief physique, becoming the battery on high might be difficult. This drawback exacerbates if there’s a GoPro digicam mounted within the entrance, because the battery can press towards and doubtlessly injury it. Mounting the battery sideways addresses this subject, permitting for a extra compact body design with out risking injury to the digicam.
Nevertheless, it’s essential to notice that the proximity of the battery to the props could possibly be a priority, relying on the body design. In some instances, it’d enhance the danger of prop strikes on the battery.
Tuning and Efficiency
Whereas it’s true that PID (Proportional, Integral, Spinoff) tuning can compensate for various mass distributions to an extent, it’s extra about how the quadcopter must work more durable to attain the identical charge of rotation on sure axes. This necessity would possibly end in completely different PID settings for every orientation. Typically talking, the axis that’s more durable to rotate would require greater PID features.
Private Desire and Practicality
Finally, whether or not or not bathroom tank mounting “flies higher” is subjective. Some pilots would possibly choose the altered mass distribution and its influence on flight traits. Nevertheless, I consider the selection usually boils all the way down to sensible causes like becoming the battery extra comfortably and avoiding injury to different parts.
Conclusion
Bathroom tank mounting in FPV drones is greater than only a development; 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 various to conventional battery mounting strategies. As with many features of drone flying, it in the end comes down to non-public desire and the particular necessities of your construct.
