I doubt I could call it the pinnacle of my life but.
I will be finishing my current modeling project within the next few days, a three meter radio controlled glider. I have been building this for over a year now, (couple of boat restorations fitted in during that time).
Once I finish it, I doubt the weather will be suitable for test flights.
I will then be like a bear with a sore head until I can decide on the next project. It takes me ages to decide what to design & build, there is nothing that I really need, just what grabs my enthusiasm.
Short term. I have a glider that I dare not fly seriously as it does not have air brakes, so I will be fitting brakes/spoilers, but that will only take a month or so. Flying a glider without brakes/spoilers is like driving a car without brakes. Get in a good thermal and it will disappear into the clouds.
I must have a project to think about and work on, ideally something that will tax my engineering skills but is achievable within my lifetime, preferably 1 - 2 years. (And I can afford).
