What is Toilet Tank Battery Mounting in FPV Drones – Installing LiPo Sideway

In the world of FPV drone, there’s a curious installing design that’s acquired attention: the “toilet tank” battery installing. This technique includes positioning the battery sideways on the drone, instead of the traditional front-to-back orientation. Let’s discuss its effect on quadcopter characteristics in this post, the advantages and downside of toilet tank battery installing.

The Concept of Toilet Tank Mounting

Toilet tank installing changes the mass circulation of the FPV drone. Picture a cylinder: it turns quickly around one axis however is more slow around the other due to the mass’s circulation. When the battery, a substantial part of a drone’s mass, is installed sideways (toilet tank design), it alters the drone’s responsiveness. Particularly, it boosts responsiveness on the pitch axis while somewhat lowering it on the roll axis. This compromise in axis responsiveness refers individual choice.

Impact on Quadcopter Dynamics

When you install the battery in a toilet tank design, you’re basically trading responsiveness in between the roll and pitch axes. A drone with a front-to-back battery will be more responsive in rolling however less so in pitching, and vice versa for the toilet tank design. This distinction in responsiveness originates from how the mass is spread out throughout the drone’s frame.

Practical Advantages

Beyond the modification in flight characteristics, toilet tank installing deals useful advantages. For compact racing frames with a brief body, fitting the battery on top can be difficult. This issue intensifies if there’s a GoPro video camera installed in the front, as the battery can push versus and possibly harm it. Installing the battery sideways resolves this problem, enabling a more compact frame style without running the risk of damage to the video camera.

However, it’s important to keep in mind that the distance of the battery to the props might be an issue, depending upon the frame style. Sometimes, it may increase the threat of prop strikes on the battery.

Tuning and Performance

While it’s real that PID (Proportional, Integral, Derivative) tuning can make up for various mass circulations to a degree, it’s more about how the quadcopter requires to work more difficult to accomplish the very same rate of rotation on particular axes. This need may lead to various PID settings for each orientation. Usually speaking, the axis that’s more difficult to turn will need greater PID gains.

Personal Preference and Practicality

Ultimately, whether toilet tank installing “flies much better” is subjective. Some pilots may choose the modified mass circulation and its effect on flight attributes. I think the option typically boils down to useful factors like fitting the battery more easily and preventing damage to other parts.

Conclusion

Toilet tank installing in FPV drones is more than simply a pattern; it’s an useful technique that affects the drone’s responsiveness and kind aspect. Whether for need, benefit, or efficiency, it provides an intriguing option to conventional battery installing approaches. Just like lots of elements of drone flying, it eventually boils down to individual choice and the particular requirements of your construct.
