Fick nåt ryck... jag tyckte Waco YKS-6 liknade YKS-7 (ålands första åländsktägda
flyg) så mycket på varann och googlade lite. Hittade att YKS-6 och YKS-7 är
samma flygmodell förutom att 6an är tillverkade 1936 och 7an 1937. Dessutom
fanns nån liten skillnad i trailing edga (vingbakkant) och leading edge (vingframkant)
som jag inte ser på nån vettig bild. Så, same same! =) Blir liksom lite lättare då, för
det finns "massor" med YKS-6 RC-modeller jämfört med YKS-7.
För jäkla många modeller dom där Waco hade!

REMARKS
A = Armed variants of the D series
S = Used in 1935 to differentiate between the current versions of the earlier (or "standard") cabin series and the newly introduced "Custom" cabin series. Became third letter in 1936, i.e.: model YKS introduced in 1934, was YKC-S and YKS-6 in 1936 (all were built under the same ATC)
1,2,3 = Used in 1935 to identify higher-powered versions of the Wright R-760, Jacobs, and P&W Wasp Jr engines. See first letters C, S, Y, Z, and second designation of D and E (e.g.: S3HD-A, CUC-1, YOC-1)
6,7,8 = Used to indicate models introduced in 1936 thru 1938; e.g.: models UPF-7 and VKS-7, introduced in 1937, remained in production until the early '40s with the largest annual production of the UPF-7 being achieved in 1941.
