A thing about the Aeroworks YAK 120. Last year one of my friends picked one up, AW was telling people these planes were perfect with the DLE 30cc gas engine, They Are!!! Size wise it's not a very big plane, it's span is 4 inches longer then the old 60 size Extras. As far as ARFs go this is one of the better ones I have seen. Only minor mods needed to the LG block. Very easy to assemble and some very good hardware. I like everything about this little plane except the price but if you want an AW plane they give you some pretty good stuff with the plane. They also over rate the required servos but they stating the best you can get for dead on 3-D. The big servos are not needed at all, this is a very light weight plane. Very stable in the air. I'm not a 3-D pilot but even an old IMAC pilot can make this one hover!! Over priced but a very high quality ARF.
