Extra 300 2.1m (83“)

There are many reasons speaking for a 50cc „every day“ plane. You want to do one flight after work ? No problem. That plane will fit in every car. You want to preserve your valuable 40% from the hard training ? Our 2.1m Extra is the perfect standby. Or maybe you are new in the aerobatic business and looking for a more affordable plane, while you don’t want do miss the advantages of a full-composite design ? Again and again, there is the answer: Our Extra 300 2.1m.

And we did our homework: Based on the very successful Extra 2x2, we increased the wingspan to reduce the wing-loading. A 50cc engine still accelerates that plane like a rocket. And another change has been done: The elevator is now pin-style hinged to get more throw.

There are some other, remarkable details realized on our smallest Extra. Check it out:

• Look at the shape of the whole plane. We streched it on purpose to give you the best flying characteristics possible in this class. Influenced by F3A and Artistic Aerobatic designs, the Extra 2.1m has a very long fuselage to track perfectly, while still having enough agility for the craziest freestyle maneuvers.


• We kept the cowling and canopy very small and compact to avoid adding additional weight. Building a full-composite airframe in this size, which is lightweight enough to compete with its wooden brothers is definitely not easy, but we made it.


• You got it: It’s all about saving weight on this plane. That’s why the elevator-servos are sitting in the fuselage, so we can use a very thin airfoil for the stab, keeping it as light as possible. Because of it’s compact size, you can leave the stabs on the fuselage during transportation with most vehicles. And if not, loosening two clips and one screw is really not that much work.


• Of course, all popular 50cc single-cylinder engines will be a great choice for your Extra – but we recommend you especially the DA-50 because of it’s compactness and low weight. A muffler tunnel for all popular canisters (i.e. the MTW TD-75, available as accessory) forms one unit with the fuselage and improves the stiffness remarkably. If you want to go totally crazy, you can use a tuned pipe with a small modification – but even with a canister, you already got tons of power.


• Another option, getting more and more popular in this size, is an electric motor. The choice on the market is huge, but we tried the most popular engines: The Hacker C-50-XL, featuring a 6.7:1 gear and the Plettenberg Orbit, a very compact outrunner. No doubt there are also other great choices available. For these two engines we offer a special mounting kit, which will fit to any other engine with small modification.

Well, we all know that the selection is huge in the popular 50cc class, so why decide for a more expensive and a little bit heavier full-composite kit ? The answer is easy: It’s about robustness and durability. If you are only doing 10 flights a summer, you probably won’t see the difference. But if you fly your airplane almost every day, the vibrations of the engine will kill your wooden plane quickly. Making it sloppy, look terrible, not flying straight anymore.

With your CARF-Models Extra 2.1m, you can laugh about that. There is no way to see any fatigue even after 100s of flights, if you look just a little bit at your plane from time to time. The whole full-composite structure is so stiff and strong, that it really resists the vibrations. Forever.
