I will defer any more answers to this thread until after our coming slope flying festival. This is my #1 flying event of my calendar and I want to have a clear head when preparing my fleet of gliders and sharing the company of the many fellow flying friends who will be there.
I should note that I will take the next month or two to review my options. These include looking a proper engine, short listed is a horizonally opposed twin cylinder 120 cc or thereabouts - DA120 or the like.
I am advised this so called boxer configuration is superior in terms of vibration.
Besides, I am aware that I am beginning to ask far too much from others including you respondents.
