K-13 TO k-7 elevator
hello all,
I am thinking of replacing a K-7 elevator and possible the whole horizontal stab + elevator with one from a K-13. I guess I will be asking Scleicher if such action is approved, but are there any oppinions out there about it ? has it been done before ? incidentally, can you do the reverse, ie use K-7 wings on a damaged K-13 ? regards Vassilios |

Ian you may find that this is a K7 conversion. Several
K7's were converted to K13 look a likes. We had four at Camphill, the fuselage was considerable wider at the waist and had a spacing section placed as you describe. The way to tell the difference is that the K13 has a sprung wheel -- I think the older ones were on the end of the skid and the K7 is not sprung. The K7 tailplane has round tips on the elevator and the K13 square ones. The rose bearing fixings are a different size and spacing again from memory the K7 has smaller and closer fixings and the front fixing bolt may be a different distance from the bearings.

The Scottish Gliding Union at Portmoak had a K13 with K7 wings - may still have it. There was an intemediate framework to space out the two wing roots, and the additional foot or two of span was said by some to give noticeably better performance than a normal K13. Personally I always preferred the Bocian ... There is/was also a K7m at Rufforth (Ouse GC, York Gliding Centre) which was a K7 with the wings moved down to K13 position. I can't remember how the root-separation problem was solved in that case, though. Ian -- |
