Thank you very much, gentlemen ! ! !

All you have given lot of informations for me. Keep the same way... all tips is ok.

Spitfire project starts after Precedent T-240 trainer finishing and flying. I'm going fit Zenoah 38 to T-240's nose... we'll see how it flies.
That plane is my first non electric plane and also, first over 40" plane (except gliders).

And of course, first I have build one scale Gloster Gladiator for my friend, because I promised to do that. Wishes to finish it with Finnish markings.
I had never own or flying before any glow or gas engined planes. Now it is time to start and learn !

If you guys want see my electric warbird pictures, I can drop few to this thread. There is 40" Focke Wulf 190A and 30" F6F Hellcat.
