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.

Fast, refined and more versatile than its 1.3m wingspan suggests, the Eflite Pilatus PC 21 brings together 6S power, strong slow-flight capability, practical battery flexibility and scale detail. We break down the best setup choices, real flying character and how it stacks up against the CNHL Super Tucano.

The iFlight Defender 20 Lite X keeps much of the original Lite's proven 2-inch platform but makes two meaningful changes: DJI O4 Wide and a conventional 2S XT30 battery system. We look at the specs, real-world flight tests, prop-guard modes, battery life, image quality, cooling concerns and whether the Lite X is a meaningful upgrade.

Balance charging uses both the battery’s main power lead and balance connector so the charger can monitor individual cells while charging the complete pack. To balance charge correctly, inspect the battery, identify its chemistry and cell count, calculate an appropriate current, connect both leads, select LiPo Balance Charge, and confirm that the manually selected and detected S counts agree before starting.
