Description

The Infinity F5J is the latest high tech ultra lightweight model to come from Slovakia. The heart of the model is the excellent wing with specially developed airfoils by Dirk Pflug. Superbly molded from biaxial spread carbon, the design has been optimised for catching low level thermals. Its 3.5m span is considered in Europe to be the optimal size for getting away from low starts, and its generous wing area gives it a low loading so it can turn tightly and make best use of the small weak thermals often found at lower altitude. Its two piece wing reduces inertia so any bumps in the air are shown very clearly. This wing configuration also makes for an uncluttered fuselage, allowing easy powertrain and RC installation.

The Infinity F5J is available in two layups:

Light - the wing is made from 40g biaxial spread carbon and the tails are from 24g biaxial carbon, giving an empty airframe weight of approx 850 g.

Performance - the wing is made from 60g biaxial spread carbon and the tails are from 40g biaxial carbon, giving an empty airframe weight of approx 990 g.

All models are supplied with nice wing and tail bags and well engineered ballast systems that can add up to 330 g to the model's weight in three steps. This makes for a very flexible model that will excel in most flying conditions.

We only stock the Pro Build version of the Infinity. This has Servorahmen servo frames fitted and IDS systems installed. Also included are a wing wiring harness with all connectors, servo covers, and push rod hardware.

See this RCGroups Infinity thread for more info.
