500–550 Class Helicopter Battery Guide
The 500–550 class covers helicopters with main blades around 420–550mm. They’re bigger than 450s, offering more stability in the air, but still easier to manage than 600 or 700 giants. Choosing the right 500 class helicopter battery or 550 RC helicopter battery is key to unlocking the full performance of these mid-size machines.
Battery Recommendations for 500–550 Size Helis
If you’re flying a 500 class machine, a 6S 3300–4000mAh RC heli battery gives you a nimble, responsive feel—perfect for sport flying and early 3D practice. For 550 size helicopters, step up to a 6S 4500–5000mAh LiPo battery for more stability and longer flight times without overloading the airframe.
FAQ: 500–550 Class RC Helicopter Batteries
Q1: What’s the difference between a 500 class and a 550 class helicopter?
A: The “class” refers mainly to blade length. 500 class uses ~425mm blades, while 550 stretches to ~520–550mm, which gives more lift and smoother performance.
Q2: What is the most common setup?
A: Most 500 helis run 6S 3300–4000mAh packs with XT60, while 550 helis often use 6S 4500–5000mAh EC5 packs for extended flying.
Q3: Can I use a 10S or 12S setup on a 500–550 heli?
A: Typically no—these classes are designed around 6S power systems. Higher voltage setups are more common in 600–700 class helicopters.
