Hello Flywilly,

I stopped all RC activities 15 years ago and I am now returning to it. I have kept all my equipment and amongst it is a Hanno Special in an Aurora 60 built in 1989.
I had put into all my engines some transmission oil and so far, 15 years later, all of them took some starting work but all ran with their original bearings, glow plug and so on. Even some old fuel (10% Castrol M, 10% Castrol MSSR and 10% nitro) that I had mixed then, worked very well.
Amazing !

Now for the real question :
As your last post on the subject was nearly 2 years ago, I am hopping that some new development in a possible source for that Hanno's piston and sleeve replacement. Sorry for stirring the knife in the wound, but your thread in the only reference I found so far for Hanno replacement parts.

If you decide not to answer, I would understand. I have been there ! 

Regards
