The Brunswick-Balke-Collender OQ-4 was a prototype drone built in the United States by the Brunswick-Balke-Collender corporation. The OQ-4 was one of a very few aviation-related ventures undertaken by Brunswick-Balke-Collender, which was basically a non-aviation company. It was similar in some respects to the Radioplane OQ-2, including a 12 foot wingspan. Although a few prototypes were built, the OQ-4 was not put into production, perhaps because Radioplane and Frankfort could produce enough target drone so that another production line was not necessary.[1] Specifications{{aerospecs|ref= |met or eng?=eng |crew=none |capacity= |length m= |length ft= |length in= |span m=3.6 |span ft=12 |span in= |swept m= |swept ft= |swept in= |rot number= |rot dia m= |rot dia ft= |rot dia in= |dia m= |dia ft= |dia in= |width m= |width ft= |width in= |height m= |height ft= |height in= |wing area sqm= |wing area sqft= |swept area sqm= |swept area sqft= |rot area sqm= |rot area sqft= |volume m3= |volume ft3= |aspect ratio= |empty weight kg= |empty weight lb= |gross weight kg= |gross weight lb= |lift kg= |lift lb= |eng1 number=1 |eng1 type= |eng1 kw=5 |eng1 hp=7 |eng1 kn= |eng1 lbf= |eng1 kn-ab= |eng1 lbf-ab= |eng2 number= |eng2 type= |eng2 kw= |eng2 hp= |eng2 kn= |eng2 lbf= |eng2 kn-ab= |eng2 lbf-ab= |max speed kmh= |max speed mph= |max speed mach= |cruise speed kmh= |cruise speed mph= |range km= |range miles= |endurance h=1 |endurance min=0 |ceiling m= |ceiling ft= |glide ratio= |climb rate ms= |climb rate ftmin= |sink rate ms= |sink rate ftmin= |armament1= |armament2= |armament3= |armament4= |armament5= |armament6= }} See also{{aircontent|see also= |related= |similar aircraft= |lists=
