Aero Subaru F-200 Model - Cox .09 & O.S. .20 FS 4T

I wanted to try the O.S. .20 FS 4T, so I asked Cox .09 for permission to borrow and experiment.
I want to share with you, my friends, the new experience of this small model, previously driven by Cox .09 and now by the O.S. .20 4T.
I have modified so that if I wish, I can replace Cox .09 there.
There is the Aero Subaru F-200 in action.
I hope you like the video. Very Happy

O.S. .20 FS 4T

Thanks Eric for giving me your opinion.
Well, it is the first time that I have such a small 4-stroke engine, I am amazed at its mechanics and operation, I cannot deny that this jewel falls in love.
I really like Cox .09 and something very different .20 4T, it has a different kind of acceleration and a flight with a special sound, really falls in love.
I am learning, I notice that they have very low fuel consumption !!
You, have you used 4-stroke engines Eric ??

Great plane, engine and video Mauricio, like always. My OS MaX 56 FS alpha - like your other OS - is an astonishing fuel saver..4strokers do not waste fuel like 2 strokers when loop charging the cylinder with the exhaust port also wide open. The higher compression ratio of 4 strokers is another contributor to their fuel economy.

Hi Andras, thanks for leaving me your comment.
Thanks for your information.
With the .56 4T and now with the .20 4T, they are my first experiences, I am very happy with these engines, they have a special charm. I'm thinking of making some other model for a .26 4T ... we'll see what I can think of Paranoid
