It is actually a little less, precise scale is 1:3.8 so span not quite 11 feet. Finished weight is projected at 50 pounds, dry, plus 6 litres of fuel, so T/w ratio is about .9 on take off. It does not require a C of A as such, but has to go through an inspection process and proving flights.
I already have two other Hawks flying, scale 1:4.5 weight 44 pounds with 36 pounds thrust engines. They fly superbly and are all equipped with state of the art, professional, dual uplink plus data downlink ( including downlinked warnings of critical parameters) radios on 2.4 GHz.
Now retired from flying big jets at least they fill one of my aviation passions !
Oh yes, the electrical system is powered by twin lithium batteries, but unlike those in the 787, my battery packs have internal electronics which monitor individual cell voltage and temperature. So far, no battery fires !
