You've got pretty large engines on your planes .

I fly WWII combat myself, but I'm just a beginner, flying Kawasaki Ki-64 with OS .25FX engine. One of the concerns here on the European side is that this is beginning to turn into pylon racing, the planes are almost too fast already.

The ACES Germany has been working on the WWI rules for European combat, and what they are proposing is either .15 -size two-stroke (8x4 or 9x3 prop) or .30 -size four-stroke (10x4 prop). They are also promoting real 'built' planes, not something cut out of foam. For me it would be a shame to destroy such a beautiful plane . Anyway, I have been thinking of building Snoopy's doghouse (read: Sopwith Camel with Snoopy as the pilot) myself for this summer.
