The name “Cox” is rooted so deep in model aviation, some people refer to all glow motors as “cox” motors. Being given a fresh face by the Hobbico family of companies, the new Extra 300 appeared early this spring to fill a much needed micro aerobat slot. Let’s see how the Extra 300 scored…
Assembly is fast and easy (under 2 min.), and the battery charges up in about another 20 min. from the factory pre-charge. Since the radio is also bound and configured form the factory, there’s little to do other than find a smooth driveway for take off. Our Extra 300 jumped right off the ground and took to the air immediately.
You’ll want to keep the rates on low until you get settled into the fast roll and slip of the Extra. After a few laps, we had it flying smooth with little trim needed. Now the fun: high rates and pattern maneuvers! The Extra has enough thrust to get out of it’s own way and let you have a little fun doing it. Rolling through arcs was a lot of fun and we even pulled off a few soft snap rolls. While you can’t hang on the prop, knife edges, hammerheads, and the typical power maneuvers are quite possible and surprisingly straight and stable.
Slightly greater than 5 minute run-times had us very pleased overall with the flight experience. Durability is phenomenal but with the bulkier expanded polyolefin FlightFlex™ airframe you’ll find the Extra to be a high-speed only glider. Landings are straight on, coming in a little hot, quick flair and touch down…in that order. Any other approach and you’ll be thankful the landing gear and airframe are so tough! An amazing value from Cox.
