After a bit of struggle, I finally finished this kit. The biggest impediment was the instructions - there are errors that cause extra work if you don't study them very closely. Also, this kit shares the same upper hull as the 9A83, meaning there are openings/slots that are not used in this build and have to be filled. The most egregious error is Step 8 where the instructions say to drill 46 holes in the upper hull - only 8 are required. The brass wire provided (180mm) is too short to do two tow cables. The instructions call for 2 x 85mm wires, they need to be 95-100 each to reach. This kit is better than the 9A83 in showing how to shape some PE, but leaves you guessing on several. Some part call outs are wrong - example: Step 17 says PE-A14 & -A15, should be PE-A12 for both. Same step calls for PE-A12, it's actually PE-A18. Step 19 - S13/S14 are reversed. Step 21 - S31/S32 are reversed. Step 23 S11/S41 are reversed. Same issue here as the 9A83 when attaching the missile canisters to the rails - if you try to snap the clamps over the rails, you'll break them, especially in the turnbuckle. You have to cut the clamps to make them fit over the rails.
