Tips on Goldberg Sukhoi
Another kit you might want to consider is the Lanier Ultimate Pitts. It's an all-wood kit with many laser cut parts. The plane looks like a hybrid which uses a Pitts style fuse and Ultimate wings. RC Report's Dick Pettit reviewed it very favorably sometime in 1999 and reprints are available. FWIW, that I have it slated for next winter's project.
The recommended engine range is 1.08 2-stroke to 1.80 4-stroke (or small gasser). weight, depending on engine should come in betweeb 11 and 14 lbs.
At 10.5 lbs my friend's Sukoi is not a floater, but neither does it fall out of the sky. It's just a good-tracking, very solid flying type of plane. After flying his I became motivated to build mine sometime in the future.
I've attached a pic of my last Pitts (a Cermark 1/4 scale ARF S2B - great flyer, but lousy quality), which I flew for 2 seasons 'till I lost it in a midair at the end of last season.
