RC J3 Cub 2.1m Maiden with preflight checks: Flight One

Описание: Carl Goldberg J3 Cub (Electric Conversion)
This classic Carl Goldberg J3 Cub has been converted to electric power with a 4S 500KV brushless motor, running a 4S 5000mAh LiPo and a 12-inch wooden propeller. It keeps that traditional Cub look but flies clean and smooth on modern gear. Powered with a 6400mah lipo.

Flight Review:
I set this plane up yesterday with minimal testing, so today’s goal was a proper field run with some spares and tools ready for adjustments. I swapped in a receiver I trust from another model, checked all control throws and throttle response, then taxied out for the first circuit.

The first takeoff showed a weaker climb rate than expected, so I climbed out to a safe altitude, turned downwind, and brought it in for a smooth landing on the east end. I swapped the prop for a newer equivalent, which helped a bit, but it still wasn’t ideal for the plane’s size.

On the second section of the flight I managed a loop and an aileron roll. The Cub handled beautifully slow, stable, and scale in the air. Battery efficiency was excellent, landing with plenty of charge left. My landing itself was fine but could’ve been smoother.

You’ll also hear my post-flight thoughts on tuning and upcoming changes to the airframe, but overall this was a solid maiden in challenging conditions. This Cub’s definitely earned its place at the club and on the channel again soon.
