Not myself. But forum member Brian John has built several very nice engines from Bengs kits. You should be able to search out threads by him showing pics etc. He seemed very happy with the kits.
yes! built 3 so far, very good quality kits, instructions in German but there are some build logs on the Bengs web site for most of the kits. The castings are very good, very easy to machine.
Part way through a Bengs 'Sophie'. First experience of their product and mixed feelings. Problems stem from my difficulties 'reading' plans and lack of skills and the 'instruction' leaflet 'translation' which makes Chinglish a simple read!! Material quality is good – results very much down to 'operator quality'! Casting (Main Beam) needed remedial work on bearing location but machines OK. Kit is mainly raw material and fixings.
Would I buy another? At the (half) price I paid for this, yes … at full price? No.
