Power Considerations for Scale and Twin-engine RC Planes
Scale setups aren’t light on draw—flaps, retracts, lights, and twin motors all pull their share. Flying a B-25 or a C-130? You’re not just cruising, you’re pushing big airframes with serious load. That’s where high-capacity packs come in: 4S, 6S, or even 12S setups keep the lights on and the flight smooth.
Matching Packs for Multi-motor Systems
Flying twins means balance—one motor surging ahead ruins the whole flight. Run a Y-harness or twin ESCs—either way, CNHL’s matched cells make sure both motors stay in sync and you don’t get that weird lopsided pull.
Common Battery Sizes
- Smaller twins and scale birds: 3S or 4S, around 2200–4000mAh keeps it light and balanced.
- Big warbirds and heavy scale: 6S to 12S packs in the 4000–7000mAh range.
- Power-hungry twins: Dual 4S or 6S setups, 5000–6200mAh each, for clean, even thrust.
Why Choose CNHL Batteries for Scale Builds?
Scale flying is all about precision—not just power. You need steady response that matches the way your plane was designed to fly. Even under full load, the pack keeps things smooth without needing throttle babysitting.
