Best Battery for E-Flite Beechcraft D18, Opterra 2m Wing & Air Tractor

In this guide, we delve into battery recommendations for three of E-Flite’s standout models: the classic Beechcraft D18 1.5m, the versatile Opterra 2m Wing, and the rugged Air Tractor 1.5m. Whether you’re soaring high, performing sport aerobatics, or embarking on agricultural endeavors with your RC, the right battery ensures that your aircraft operates at its peak potential.

HRB 4S 3300mAh 60C for Beechcraft D18

Power and Performance: The Beechcraft D18 is well-regarded for its scale details and Smart Technology, making it a favorite among many RC enthusiasts. With the HRB 4S battery’s high discharge rate of 60C, I noticed an evident boost in power, allowing me to take the Beechcraft D18 to greater heights, especially at full throttle. This means more impressive aerial displays and longer, uninterrupted flight times.

Consistency: After running several tests using a battery tester, the capacity and discharge rate of the HRB battery align very closely with what’s advertised. This is essential, particularly for an aircraft as sophisticated as the Beechcraft D18. It ensures the plane can harness consistent energy output every time.

Battery Balance: The even voltage balance across the cells in this battery is commendable. Even after tens of charge cycles, the balance remains impeccable. For the Beechcraft D18, which boasts functional features and Smart Technology, this consistent battery balance ensures that all onboard systems work seamlessly and efficiently.

Gens Ace 3S 2200mAh 25C for Opterra 2m Wing & Air Tractor

The Gens Ace 3S 2200mAh 25C battery offers an impressive combination of performance and reliability, making it a choice battery for both the Opterra 2m Wing and the Air Tractor. Let’s explore the benefits of these two distinct RC airplanes:

Steady Performance: The Opterra 2m Wing, known for sport aerobatics and soaring capabilities, requires a consistent power supply. The Gens Ace 3S battery’s internal resistance, observed at 0.010 ohms, is outstandingly low. This ensures that the power delivered is consistent, allowing the Opterra to perform at its peak for sporty maneuvers or smooth glides.

Safety and Durability: After pushing the Air Tractor 1.5m – renowned for its detailed scale and functional features – to its limits at full throttle, the Gens Ace 3S remained only slightly warm upon descent. This is a testament to the battery’s ability to handle high-demand situations without overheating, a key factor for ensuring longevity in your flights and the overall lifespan of the battery.

Value for Money: Given its robust performance, the Gens Ace 3S offers remarkable value. I have several Gens Ace lipo batteries in my collection, and their cost-effectiveness, coupled with their performance, makes them a favorite.
