Russian Raduga Rainbow 7cc

A 1975 vintage engine. Special Export model - weighs about 8 oz with silencer. This one is pristine and I have been told that it is has a reputation for being quite a powerful little engine for 1975. This one has never been run or mounted.



MKB Raduga (Russian: МКБ Радуга, meaning Raduga Design Bureau, where raduga literally means "rainbow") is a Russian aerospace company, concerned with the production of various missile systems and related technologies. It is headquartered in Dubna in the Moscow Oblast. It was formerly a division of the Mikoyan-Gurevich design bureau, before being spun off as a separate OKB (design bureau) in March 1957.

Радуга is cast on the crankcase.

The 7cc Raduga engines were produced under a state sponsored program for Russia's own fliers. Originally these were produced for U/C Stunt and then modified later for Radio Control. The Raduga was built over some 6-7 years in small quantities and were well proven before R/C use. Most collectors and fliers in U.S. will find this an unusual item as it was never exported to the U.S. from Russia.
