What Battery Does the Eflite Gee Bee R2 1.0m Actually Want?
The Eflite Gee Bee R2 1.0m is designed around a 4S power system and rewards pilots who pay attention to battery fit and balance. Because the CG range is tight, even small changes in battery length or weight can noticeably affect how the aircraft feels in the air.
Recommended 4S Battery Range for Gee Bee R2
Based on real-world flying experience, the Gee Bee R2 performs best with 4S packs that install easily and allow the CG to be set without guesswork.
4S 3300mAh: A well-balanced option that keeps the model light and responsive while still delivering strong performance.
4S 3700mAh: A good choice if you prefer slightly longer flight times and a more planted feel, as long as the battery fits cleanly in the bay.
4S 3200mAh Shorty: Ideal when space is tight and you want an easier time achieving the correct CG on the Gee Bee R2.
XT60 Batteries on an EC3 / IC3 Airframe
The Gee Bee R2 airframe typically uses EC3 or IC3-style leads, while many pilots already own XT60 batteries. Instead of modifying the model, a dedicated XT60 to EC3 adapter offers a clean and reversible solution.
Using a short adapter keeps the installation tidy and allows you to standardize your batteries across multiple models, including other Eflite sport planes.
Why Battery Choice Matters More on Eflite GB R2
Aircraft in this class, sometimes casually referred to as a GB R2 among experienced pilots, tend to be far more sensitive to balance than typical sport or trainer models. Choosing a battery that fits naturally—rather than simply chasing the highest capacity—helps maintain predictable takeoffs, smoother approaches, and more consistent landings.
