So I just scored this amazing little gem. It’s a vintage, no longer produced OS/Graupner Wankel. 4.9cc, single rotor, about 4.9 HP (!).
I’d eventually like to build a display/test stand, but in the meantime I’ll need to keep it healthy.
It has great compression and I do have the muffler though it’s not pictured here.
Can anyone with nitro RC plane experience give me some tips on how to maintain it while static? Is there a certain type of oil I can inject into the ports? How do I maintain apex seal health? Is it safe to turn over by hand from time to time?
Thanks in advance.
