The Avios Catalina has definitely built a fan base, and it’s easy to see why. Between the detailed design, smooth flight handling, and its ability to tackle both land and water, it’s hard not to love it. Here’s what some fellow pilots have to say:

“The Catalina quickly became one of my favorites. The detail is impressive, it flies smooth and stable, and it handles water takeoffs better than expected.”

It’s clear—pilots love the size, scale looks, and handling of this model. If you want to get the absolute best out of your Catalina, we strongly recommend pairing it with a CNHL Black Series high-discharge LiPo battery. These batteries deliver the kind of reliable power and longer flight times that big RC seaplanes like this really benefit from.

Quick Tips for Getting the Most from Your Batteries

• Always use a balance charger—it keeps the cells in check.
• Try not to over-discharge the battery; it’s an easy way to ruin it fast.
• Inspect your connectors and wires regularly—you don’t want loose connections mid-flight.

A Quick Heads-Up

If your setup needs XT60 plugs, no worries—you can easily grab an EC5 to XT60 adapter connector. It’s a simple little tool that makes sure everything connects safely and smoothly.

Final Thoughts

Choosing the right LiPo battery isn’t just about numbers on paper—it’s about getting the kind of flight you really want. The right battery keeps your Avios PBY Catalina flying
