I have an EF Yak and my friend has the TOC1 (Aviation Models) 87" Yak 54 and I can assure you this plane is no EF reject. The KMP Yaks were well known the be EF Yaks, but not the TOC1 planes... Do you have any additional info to support this claim?

These planes are built completely differently and have little in common except that they are both Yak 54s... When you put them side by side the differences are very apparent. We did the maiden flight on the TOC1 today and it went very well. I think my EF will be lighter since it has CF tubes and composite gear (it should get its maiden flight next weekend), but the TOC1 Yak flew awesome!
