MDM-1 FOX from Robbe


The MDM-1 FOX is a two-seat aerobatic legend in the glider sky, in the man-carrying, as well as in the model construction area. This has good reasons, because the machine was developed for uncompromising aerobatics and offers many expansion possibilities (EDF or turbine drive). The potential of the FOX is far reaching!
The mold-painted full-Gfk kit offers all the prerequisites for this and has received numerous reinforcements made of CfK that we have tried and tested.
We have deliberately chosen a scale of 1:4 to give you a compact, thoroughbred aerobatic glider with the flight characteristics of a large model. Therefore we also deliberately chose a 4 flap wing to give you the possibility to warp the airfoil accordingly and adapt it to the flight conditions, as well as to increase the maneuverability around the longitudinal axis in aerobatics.
The wing stub is made of 18x1mm aluminum tube with solid CfK rod inside. The included parts of the cockpit even allow for a prototype-like extension at your own discretion.
The flight characteristics can be classified as extremely good-natured. The FOX flies in any situation as if on rails, even in aerobatics it reacts agilely and dynamically.

Although I do my best to complete this library, you may not find the model you are looking for.

In this case, do not hesitate to ask me to add it : You're not bothering me. Please be patient, depending on my workload, I may take a few days to work on your model and gather information.

I'm sometime asked to add a non flying model to this library but unfortunately, it's not the focus of this website
