EZFW scale 1:2.5 wheel 140 mm

Following the trend towards light and stable undercarriages, we have switched the entire range of our undercarriages to retractable undercarriages, which consist of CFRP side parts and aluminum uprights. All components have been modified to be lightweight and yet stable.

The side parts of the undercarriage on a scale of 1:2.5 with a 140 mm wheel are made of 4.0 mm CFRP. All milled edges are provided with a 45 degree phase, so that these parts do not pose a risk of injury and the haptic is very pleasant. Servo wings for a standard-sized servo are installed on the left and right of the side panels as standard. This eliminates the need to purchase additional servo mounts and the servos for the wheel drive and the brake servo can be installed directly. It is intended to be fixed with M3 screws, the holes that match the servo are already available in the servo mounts. We supply the appropriate screws and lock nuts.

Weight-optimized and shapely design thanks to CNC-manufactured geometry. Due to the mechanical design, the wheel is firmly locked in the extended/retracted state. This means that the wheel cannot be extended by centrifugal forces, e.g. during a loop. The undamped version is fastened in the glider between 2 frames

- the attachment in the glider in the damped version is done on a main frame, the movable part of the undercarriage is only guided laterally in a thin frame at the back
- the installation height of the EZFW in the fuselage is variable
- the moving parts are mounted in brass bushings

The basic equipment consists of:
- the two side parts in 4.0 mm carbon
- the two swingarms in 5.0 mm aluminum (mirror polished)
- the required spacer bolt
- Servo mounts for two servos
- the swivel mechanism incl. drive lever
- the required stainless steel screws
- 1 solid rubber wheel 140 mm from FEMA (the FEMA wheel is equipped with ball bearings)
- Two front flange plates for attaching the landing gear in the main bulkhead
(these allow the chassis to be moved backwards/upwards for anti-vibration mounts/suspension)

Total weight of these components 690 grams

The trolleys have a modular structure and can therefore be put together individually
