Me too I've recently ordered a 0.074, and I'm about to write an e-mail to shopatron, the info they give me is confusing!
The emails tell me one thing, but my account gives me like 2 different versions more. In conclusion, I have no idea of when am I going to get the engine![:@] Furthermore, they "had to split" my order in 2 packages, for some obscure reason (it's a 0.074 and a few spare pieces, is it so much volume?).
Sure, I'm going to ask a few questions. What I hate most: "the engine is expected to be delivered in 2-4 weeks", it's going to be a looong wait, I'm really anxious to know the cause.
