I never thot a GWS Slow Stick was beyond anybody- but if it is not a known type model to some-I guess it is beyond the realm-
For those who spent their modelling years building flying heavy models - I really suggest (with enthusiasm) that you blow a few bucks on one of these very basic trainers and flatten out the wing and add ailerons
The resultant model is great for showing others how to fly - it is simple to repair and all the laws of flying can be demonstrated the good part is that the accidents are far fewer because the mistakes simply do not result in sudden "departures" so common on with many older types which were really never good trainers.
The larger models I added here -are all fully aerobatic and a couple are very faithful to scale
Scale models do not need to be heavy
the usual problem is that the builders /designers of the models simply have never learned good building skills
these skills are of more value (unfortunately) than an extensive background in aeronautics and aerodynamics.
One of my earlier postulates was that
"if the model is too heavy , none of the rules of flying apply".
