As You perhaps know, Oberursel UI is out of stock currently. The reason is that this model do not meet my expectation... To tel you the truth, I think, that the crankcase is awful... It was my first engine in 1:32 scale. Now I see, that the quality of casting is really low, what is caused by technological section. The form resists only 4-5 pieces, and I need to prepare another one. I don't want to sell a trash, so I decided to terminate the production.
I'm planning to prepare a new crankcase, cutted as in the case of Oberursels U0 and UIII, so do not worry. I just need to finish my started projects.
All the best, Lukasz
