As I mentioned - I honestly do wish you all the best. There really is no need for you to get hot under the collar - this hobby is supposed to be fun and if your engines are every bit as good as you tell us (I don't have one to comment and have no intention of owning one), then I am sure you will most definitley enjoy the hobby. I reiterate, from what I have heard they are a reasonable product.

Now it is time for you to back up your claims
Patent numbers or details?
Bearing specifications as installed on each SE engine?

And a final question - QC, Do you have a detailed system and what is it based upon?
Is it based Specific inspection criteria, Specific measurement methodology or other means? and feel free to give some detail on that

By answering those sorts of questions, I think you may do more good for your brand than being simply defensive. I am glad I can help you get exposure and like to help where I can for truly great products.
