Pharoah,

The new ZVEZDA brand kits are quite good. The KA-50 and KA-52 kits are among the best helo kits around. Their new Mi-8 and Mi-17 are both good, but have problems with the shape of the cockpit windows. AMODEL does lots of Russian helo models, but their mouldings are low-pressure, so they require alot more cleanup work on the modeller's part. Airfix's KA-25 Hormone is a classic good kit, and it has been reworked and improved by Sky High, which is an off-shoot of AMODEL. The best Mi-24 Hind kits are Hasegawa and AMT-Ertl, although that statement is arguable.
Don't shy away from them - there's lots of variety among the Russian and Soviet subjects. Not to mention tons of unusual 3rd-world markings to choose from!
