Hello,
I live in Australia, I watched a video of 15cc and 26cc engines, originating from this forum.(2010?)
Coincidentally I have just these same engines, they are still available in Australia.
I have been flying nearly 50 yrs (where did that time go!)
Control-line and free-flight early, radio for about 45yrs (bit of a gap while raising family)
Now flying mainly petrol powered models in 15-20cc size mainly, mostly Ugly Stick type models,
I still think for an over 50yr old design is great, and I also use them for aero-towing medium gliders. (3m span)
From what I have looked at so far on the forum, It shows that aero-modelling is fairly much the same,
wherever you fly in the world.
cheers from Australia. 

Cheers, and welcome to the forum
