Interesting you brought this up! I'm drawing a Sukoi 9 in 1/8 scale. Power is going to be a Wren or edf. My mind hasn't gelled about the myriad of choices, yet. It'll be ~42" span, ~85" long and the classic suck and blow tube fuse will be ~7" dia. My second choice was the Mig 21 but it has a more cluttered fuse. The Sukoi is very 'clean'!
