Now i know people use a wide range of electric set-ups that may come out lighter, but the above is an interesting comparison. because as i stated earlier the only main weight difference is the added reciever battery and slight added wood on firewall for support. there is only slight differences in weight therefore power will be the only concern. Will the 5.03cc's be enogh to pull this aircraft, who knows, hopefully my maiden later in the week will test this out. in theory the plane should come out around the higher stated 800gram mark, but from what ive heard this motor pulls 1.3-1.4kg static thrust. correct me if im wrong but that sounds like a healthly almost 2:1 ratio, or a 1.75:1 or something like that i'm not sure of the exact calculation.
