Hey Chris, thanks for asking!
So dang busy with the day job and family its hard just to get time to post here... Thomas and I text each other every so often as he is going to use one of my reductions on his Kolm engine in his TA-152.
Unfortunately im not doing any reductions for the DLE engines as engine cases dont really work for my designs. If your looking gor a reduction to go on a 55-60cc engine I do make one for the DA60 though... I always wanted to put that one in a 1/3 scale WWI biplane.
Shoot me a pm if you want,
thanks, John
