You bet you can. A friend has that H9 Sukhoi; a beautiful model. And who wouldn't be proud of the puppy below (EF Yak 54 ARF)?

I hear this a lot at my field. Those guys are mostly scalers, and as far as they're concerned, anything other than a giant-scale warbird with 27 tons-per-square-inch wing loading is a "sh^t plane". Their models all have proper color schemes/markings and scale details. Then you look closer, and you see servos with paint overspray all over them, receivers and switches older than I am, sloppy wiring, etc., etc.

And watching them do their thing is a hoot. They spend a LOT of time on the ground, either sitting or on their backs, fiddling and tinkering. One guy spends so much time under his model, I told him I'm going to buy him a creeper for Xmas. All of this for one, MAYBE two flights. But they're enjoying themselves; and the sport contingent enjoys watching them... its better than TV.

Moral of the story: Don't be a snob unless YOUR feces is consolidated.
