Best 4S LiPo Battery Options for the Freewing BAC Lightning 64mm EDF
The Freewing BAC Lightning 64mm is designed around a 4S power system using packs in the 1800–2200mAh class. These batteries keep the jet light enough for confident hand launches yet still provide strong vertical climb and the distinctive jet-like sound of a 12-blade EDF. For pilots who prefer extended flight times or rolling takeoffs, larger 4S packs can be used as long as the aircraft’s center of gravity remains stable.
How to Select Capacity and C Rating for a 64mm EDF Jet
EDF jets pull high instantaneous current during acceleration, vertical climbs, and full-throttle passes. A higher C rating reduces voltage sag and helps maintain thrust throughout the flight. Capacity determines the balance between weight and duration: smaller packs improve launch characteristics and agility, while larger packs increase flight time at the cost of added mass.
Hand Launch vs. Rolling Takeoff: Why Battery Weight Matters
The Lightning hand launches exceptionally well when using 2200mAh-class packs, allowing the jet to leave the pilot’s hand cleanly and climb without hesitation. Heavier packs, such as 2500–3000mAh, are best paired with rolling takeoffs using the optional landing gear. These combinations offer noticeably longer flight times and increased energy retention in windy conditions.
Understanding Connectors, Adapters, and Fitment
Most 4S packs suited for this model use XT60 connectors, which align with the factory ESC. Larger 4S performance packs equipped with XT90 connectors may also be used when paired with a reliable adapter. It is important to ensure that wire routing does not interfere with the spring-loaded battery hatch and that the pack fits firmly without compressing the surrounding foam structure.
Community Impressions of the Freewing BAC Lightning 64mm
The Lightning has generated strong enthusiasm among EDF pilots, many praising its unique silhouette, stable flight characteristics, and the novelty of seeing such an iconic British interceptor represented in foam. Numerous pilots have already placed orders, with some expressing intent to purchase more than one. Others are calling for larger 70mm, 80mm, and 90mm versions, reinforcing just how well this aircraft has been received by the community.
