Yes Dragline and Mike C . They are expensive and can drive you nuts but the results are amazing. Here are a few I have finished and two I have not. But working on them as well. The two Porsche engines are going in a 935/78 and the monster 12 is going in the 917/30. Finished the 1/24 Ferrari 166, a 1/12 cobra 427 and the Ferrari P4.
