Some model flyers impede the high weight during transport. With a span of over 4 meters, the model is naturally bulky and requires a suitable transport vehicle or the possibility of removing the support surfaces.

There is also some criticism of the price of just over 2,200 euros, with most buyers still consider the price-performance ratio to be fair when considering the size and quality of the model.

Test results and performance

Impressive flying properties

In extensive tests, the Giant-Scale model was able to convince with excellent flight characteristics. With a recommended motorization between 100 and 200 ccm, the model offers plenty of power reserves.

With a 100ccm engine, the Carbon Cub already reaches an impressive gradient of about 20-25 meters per second. If a more powerful 200ccm engine is used, it is even possible to achieve gradients of more than 30 meters per second, which is exceptional for a model of this magnitude.

Impress flight times

Flight times vary depending on the engine and flight style used. With a typical 100ccm petrol engine, flight times of 30-40 minutes are easily possible. In the case of economical driving and a larger tank, flight times of more than one hour can even be achieved.

These long flight times make the big Cub model a perfect companion for relaxed afternoons in the airfield. The combination of comfortable flight behavior and long flight time ensures an incomparable flight experience.

Material quality and processing

High-quality materials as base

The huge Cub model convinces with its high-quality processing. The structure is based on a laser-cut construction of light balsa and plywood, which ensures optimal strength with minimal weight.
