Can't imagine what could be wrong with it. Mine should be finished this week and it looks great. The kit is very good and instructions for Kyosho's get better each time I build one...
I found the right spray color for the blue used (sapphire blue from Top Flite - TOPR7226) and have painted the landing gear and struts/cabanes... Looks very good.
The only flight test I've read here makes it sound like a squirelly little bipe... but that's exactly what a bipe is

I just built and flew the Kyosho Super Stearman and am hoping for similar flight handling (maybe more radical).
Hope to have first flights this weekend... We'll see.
