Hi model bear,
There isn't much in the way of Grokhovsky's lighties on the net as I've found out today. His G-38 twin boom fighter and the G-37 container plane are all I could find on the net. If you can get your hands on a copy of the late Bill Gunston's book The Osprey Encyclopedia of Russian Aircraft 1875-1995 he has a section on each of the Soviet/Russian designer/constructors during that period. Another designer I forgot to mention in my previous post was Moskalev. The Soviet/Russian designers produced some very pretty light aircraft and I feel it's a shame that more of them aren't available as plastic kits. When I get some time I'll dig up my very well worn copy of Bill's book and list the lighties here.
Then there are the other eastern European countries that built aircraft; Poland, Czechoslovakia, Romania, Bulgaria, Latvia, Lithuania, Estonia to name some off the top of my head at 1:30 am.
I've found my copy of the book and Grokhovsky did produce a light container plane of similar concept to the later American Packet where a shaped container was wheeled in under the aircraft and flown to a destination somewhere and an empty or full container flown back. The designer I was trying to think of was Gribovskii who designed a series of very pretty single and twin engined lighties before WW2 and a troop carrying glider during WW2.
Cheers,
Ross.
