this 5 inch frame attracted my interest as its only 70 grams of weight (verified). It has 5mm thick arms with narrow surface and a special configuration of 140mm front width and 175 back width. So it should be quite fast and agile. Plus i got some quite new 2206 DYS fire motors that can do 4-6S batteries in the shelf.
So found more things in the shelf – an unused 35A racestar ESC, a noname F4 flight controller, an old GEPRC VTX and a R9 mini receiver. So lets go!
dry weight of less than 275 grams! thats nearly 50 gramms below my current 5 inch racer setup.
