# Taking the AtomRC Penguin for a Test Flight: A Versatile FPV Fixed Wing Drone

Looking for a fixed-wing drone that offers versatility for FPV use? Look no further than the AtomRC Penguin. In a comprehensive review by Painless360, he puts this uniquely-designed drone to the test, providing valuable insights and his final verdict.

**TL:DR – The Good and Bad**

The AtomRC Penguin comes with several impressive features. It boasts twin motors, providing powerful thrust for aggressive climbs and easy hand launches. With a wide speed range from 10 mph up to over 70 mph, it offers versatility in flight. The efficient cruise at lower throttle settings allows for longer flight times. The durable foam construction holds up well, and it’s capable of basic aerobatic maneuvers like loops and rolls. Additionally, it has a large internal capacity for big batteries up to 4200mAh, and its quiet operation is thanks to the 6-inch props.

However, there are a few downsides to consider. The flight controller is mounted far back from the CG point, which affects balance. The preset throws are too high, making the drone overly sensitive. It doesn’t excel at very high speeds over 90mph, and the airframe remains bulky when broken down for transport. There are also some concerns about the long-term durability of the nose section, as it tends to shovel grass and dirt during landings.

**Straightforward Build with Room for Improvement**

Constructing the AtomRC Penguin is a breeze, taking only a couple of hours without major issues. Painless360 opted for ExpressLRS over SBUS to avoid telemetry problems with the flight controller. Upgrading the firmware to iNav 6.1 enabled key fixes and improved AHRS. However, the placement of the rear-mounted flight controller could be improved to enhance balance and create more space for components.

**Impressive Speed Range with Twin Electric Power**

One of the standout features of the AtomRC Penguin is its twin motors, which generate substantial static thrust for rocket-like climbs and effortless hand launching. It offers an impressive speed range, cruising efficiently at 30mph and 3.5A draw at just 1/3 throttle. At 50% throttle, it reaches a speed of 46mph and 8A, while its top speeds exceed 70mph at full throttle.

The Penguin’s unique shape doesn’t compromise its performance. It tracks well and feels stable in the air. With adjusted throws, the roll and pitch response is crisp without being overly sensitive. The drone’s ample thrust and control authority allow it to perform aerobatic loops and rolls with ease. Additionally, the 6-inch props keep noise levels pleasantly low.

**Durable Airframe with Some Minor Shortcomings**

The foam construction of the AtomRC Penguin has proven to be durable, with the drone holding up well during testing. However, there are some minor shortcomings to be aware of. The placement of the flight controller and the high preset throws could be improved for better performance. Additionally, the bulky airframe when disassembled for transport may be inconvenient for some users. There are also concerns about the long-term durability of the nose section, as it tends to shovel grass and dirt during landings.
