I've got the big yellow sukhoi and love it. A Saito 180 is a stump puller of an engine...your gasser should be fine (although I'm not well versed in gas engines). But the plane itself is beautiful.

I'll post some video of it shortly (with TME smoke system, etc). JeffC has the smaller sukhoi and I'm in the midst of building the 60-size Giles....more on those later.

For some flicks of the yellow planes in action, check out the following URL:
