The Avios Albatross V2 remains one of the more distinctive twin-engine RC flying boats, now joined by a new USAF Search & Rescue scheme. This guide explains what really changed from V1 to V2, why the USAF release is not a true V3, how 4S and 3S battery setups differ, and what real-world flying experience reveals about CG, water handling, stall behavior and radio setup.

An AC LiPo charger plugs directly into a wall outlet and is usually the simplest option for home charging. A DC charger requires an external power source but can offer more charging power in a smaller package and greater flexibility for field or high-output setups. AC/DC chargers combine both approaches, although their maximum output may be much lower on AC power than on a suitable DC supply.

The HPI Stage D24 takes proper rear-wheel-drive RC drifting down to 1:24 scale with an adjustable chassis, gyro, licensed Toyota GR Supra hardbody and a $120 RTR price. We compare several early hands-on tests to see how easy it really is to drift, why surface and gyro setup matter, whether brushed power is enough, and what battery fits the Stage D24.

The Hobby Plus DKR4 Fortis brings Dakar-inspired rally truck styling to the 1/18 scale with brushless power, a 2-speed transmission, portal axles, working winch and extensive scale detail. This review looks at how it actually drives, why its high center of gravity matters, where the locked drivetrain helps or hurts, and what kind of terrain suits it best.

The FMS and Arrows Hobby Viper 30mm may be tiny, but it does not fly like a slow micro trainer. This review looks at its 2S 30mm EDF power system, RTF and PNP differences, ELRS/SBUS flexibility, stabilization, battery choices and the flying techniques that matter most.

The Durafly EFXtra and Eflite V900 proved that a compact foam RC plane could deliver serious 100+ MPH performance without becoming large or complicated. This comparison looks at their speed, battery systems, handling and design priorities, then asks a bigger question: what if the same lightweight 975mm-class formula were developed around 6S power from the beginning?

LiPo charger wattage is determined by battery voltage and charging current. Multiply the battery’s full-charge voltage by the intended charge current, then add practical headroom for charger losses, input limitations and other active channels. A 4S 5000mAh battery at 1C needs about 84W at the battery, while a 6S 5000mAh pack needs about 126W. Charging two identical batteries independently roughly doubles the required output.

The HPI Stage D10 combines an officially licensed Ford Mustang RTR Spec-5 FD body with a genuinely adjustable rear-wheel-drive drift chassis. From the entry-level Brushed RTR to the sensored FLUX version, this is a platform designed to make RWD drifting approachable without leaving experienced tuners with nowhere to go.

The Freewing MiG-29 V2 Red Star keeps the imposing twin-80mm Fulcrum platform but makes meaningful changes to power, thrust vectoring, stabilization, landing gear and field setup. Here is what matters most—and why battery weight may be just as important as capacity.
