A friend of mine built his last winter, builds like a typical Dynaflite, it's a builders kit. He had an ASP .75 on it and couldn't get it to run right, but had plenty of power when it was flying the few times he had it up with that engine. Later he went with a .91 Surpass on it, and loves it. Both Engines were more than enough, and flew it well. I am not sure about a 35cc on this, anyone else fly one with Gas? If your weight is ok, and she will be on the CG ok, then I say go for it. I flew it the other day, and it's very gentle, and flies nice and slow-very scale. Be alert on the take-offs, and quick on the rudder, as with any WWI Tail dragger. Have a blast! This baby looks awesome in the air!!!
Post some building pics. Happy building!
