Аккумулятор LiPo для FMS Beaver 800 мм

What the Beaver 800mm Really Wants From a 2S Battery

The FMS Beaver 800mm is not a “high-power hotliner” type of plane—it’s a small, detail-rich, GPS-equipped RTF that flies best when the 2S pack fits properly and keeps the CG correct. In real use, the biggest improvement from a good battery is not top speed; it’s how predictable the plane feels in stabilized/auto-level modes and how consistently it returns the same feel from flight to flight.

Quick Fit & Connector Check (Read This Before You Order)

• Connector matters more than specs. Many Beaver 800mm kits use a “JST-style” main lead on the included 2S pack. Before you order extra packs, compare your airplane’s battery plug shape to the product photos.
• CG matters: This airframe is sensitive to where the battery sits. Most pilots end up pushing the pack forward to keep the nose honest, especially when flying in wind.

Recommended Batteries for FMS Beaver 800mm

1) Light-duty / short-session spare (2S, JST):
CNHL MiniStar 300mAh 7.4V 2S LiPo Battery (JST) – 3 Pack
If you want a very small pack for quick bench checks, short hops, or ultra-light feel in calm conditions, this can be a useful spare. Just remember: a very small pack may force you to push it far forward (or add nose weight) to keep CG correct.

2) “Closer to stock size” main option (2S, JST & PH2.0):
2 Packs CNHL MiniStar 900mAh 7.4V 2S 30C LiPo Battery (JST & PH2.0)
This is the more practical everyday size for the Beaver if your connector matches (or you’re already set up with the correct adapter). It gives you the “normal” 2S feel while also making it easier to tune CG without doing anything weird.

Simple Setup Tips That Prevent Beginner Crashes

• Don’t chase auto-level at low airspeed. If the plane gets slow and mushy, add a touch of throttle first. Auto-level can hold a weird attitude if you let it get behind on airspeed.
• Set a conservative low-voltage habit. Small 2S packs can drop fast near the end. Land early and keep packs healthy instead of “one more lap.”
• Buy spare props. This airframe’s prop setup is not a breakaway style, and cold/bad landings can snap blades. Spare props are cheap insurance.
