Max winch weak link: 630 kg (blue)

Tyre pressure: 50 psi (3.5 Bar)

Semi aerobatic (without water), cloud flying is permitted.

German (LBA) type certificate No 328.

The A model has an all moving tailplane (a balance tab is mandatory in UK). The B & C models have conventional tailplanes. The C model has (lighter) carbon fibre wings.

To check the flap gas strut. With the flaps in -7° push the flaps down to 0°. They should return to -7°. The force at the flap TE root to move the flaps from -7° to 0° should be 7.0 to 8.5 kg (15.4 to 18.7 lb).

Use the static vents under the wings for the ASI and the front and rear fuselage static vents for varios.
