Suspension strut set for the Wilga from the company Frisch Scale 1:3.5
CHANGE from 08/11/2020:
For technical reasons, the struts are approx. 10 mm longer than the gas pressure springs used as standard. This cannot be changed either, as otherwise the required spring lengths cannot be accommodated or the spring deflection would be too short if this were compensated for with a shorter piston rod. As a result, the Wilga on a scale of 1:3.5 is steeper when using the spring struts, since the installation angle changes.
Furthermore, the company Kempf Modellbau has taken over the production and sale of the Wilga from Alex Frisch. During the revision of the kit, the steering knuckles were changed, among other things. In the steering knuckle, the previously used M6 screw as the pivot bearing of the steering knuckle was replaced by a fitted screw, and wheel axles with an M8 thread are now used.
To respond to these changes, we 1:3.5 scale new steering knuckles made. With these steering knuckles, the overall length of the struts is compensated for by moving the pivot point of the strut to the rear and attaching it further away from the steering knuckle. for Wilgas, which were acquired from Kempf after August 1st, 2020, you should let us know after your purchase!
The struts can now only be ordered as a set, consisting of
- 2 spring struts (adapted to the model weight according to customer specifications)
- 2 steering knuckles (material aluminum AW 7075, mirror polished, M6 thread for wheel axle and for the pivot bearing of the shock absorber)
- 4 stainless steel spacers
About the technique:
The spring strut for the Wilga consists of a combination of a oil pull brake and one preloaded built-in spring. The undercarriage is dampened by the spring, the oil damper prevents the model from jumping away as a result of the spring snapping back. As a result, the model sucks itself firmly after it is placed on the floor. The shock absorber even copes with rough impacts on hard landings without complaint. The model already springs when driving on the square.
The preload of the spring can be changed by the user himself. To do this, the attachment on the side of the landing gear is unscrewed and the outer immersion tube is pulled off. The preload of the spring can now be changed using a threaded ring on the oil damper. This process only takes a few minutes and can be done on site. In this way, the suspension can be perfectly matched to the respective needs.
A higher spring preload causes the model to deflect later when standing / when pushing / when cornering. The cushioning becomes harder.
A lower spring preload leads to earlier compression, but this is probably not desirable when cornering, since the model will then compress too early on the outside of the curve.
The strut is designed as a dip tube, with the inner dip tube sliding in the outer dip tube with a 50% overlap. This reliably prevents the spring from buckling and the shock absorber is stable. The immersion tubes and the fastening parts are made of stainless steel.
Two stainless steel inserts are supplied for the mounting eyes. These are intended for the manufacturer's M6 screws and prevent the shock absorber from being stuck to the chassis. This allows the mounts to move during compression.
The use of high-quality industrial springs and industrial oil dampers as well as meticulous manufacturing in combination with exact design for the model creates a product that you will enjoy for a long time. We give a lifetime guarantee on the product on the wearing parts. However, this does not apply to mechanical damage of any kind.
When ordering, please MUST indicate the model weight + - 1 kg exactly
