I recently built the Zvezda BF-109F4 and found the kit "over engineered" as you say. The detail was very high and fit was great. It built into a really nice model, one of my best. I am a detail junky and I really enjoy adding as much as I can to these, so the Zvezda fit the bill for me very well.
I am glad you reviewed this one as I have been eyeing it for awhile now and was curious if it were designed similar to the 109, and clearly it is. So, that seals the deal for me. When I am ready for a La5-FN, I will be getting this one.
Thanks,
BK
