I'm curious about the new U-Can-Do SF. Apparently the 40 sized U-Can-Do has been discontinued. But the 60 sized U-Can-Do is still available, and Great Planes added the SF version. The SF appears to be slightly smaller than the 60 and slightly larger than the 40 and can be configured for electric or glow.

Has anyone tried one?

I'm dabbling with an SF with a Saito 100. I've been outta the hobby too long to be comfortable with it but some of its quirks seem to have been carried over from the others. Tons of KE coupling, weak firewall and LG mount and so on. Flies nice but word is still out on its 3d capabilities.
