thought i might share a model i scratch built...some of you might not have heard about the f4d skyray..its history in the us navy was pretty short..it did set a number of speed and time to climb records but was a bit ahead of its time and the propulsion and control systems were a behind the curve for this jet. But...as a model...it makes for a wonderful flying jet! Lots of wing area...stable delta design...no bad habits and a very gentle stall. This one is powered by a freewing a10 fan amd a 6s 6250. Weighs about 6.5lbs and is about the same size as the freewing a4. Also has the a4 retracts in it. Built from depron foam and then fiberglassed. Built directly off of a 3 view...in what i like to call improv building...where i mostly build and design on the fly as a i go...granted..many hours of fore thought goes into the design before i ever cut anything. I actually framed up 2 of these...and need to finish the other one for my friend. But heres some pics of the build and the finished product. Also a video by my friend chris.(he also designed and printed the nose cone and ducting)..the rc geek. If you dont subscribe to his yt channel...you need to! Tons of awesome videos on his channel.
