The DA's have been around for a long time thus it is proven technology.

The weight must have been lost from some part of the engine im just wondering where. Is it going to compromise the longevity of the motor? Id say no one knows this as they have only been around for three months.(if that). We are not talking about a small drop in weight from my understanding they are still using the same materials so what gives????

100 engines is not a large amount.

Dont get me wrong im interested in new technology just want to understand it.

Also i read a lot of bad press about the BME 110 but as you said this may have come from people who dont know a lot about engines and just slam it together and expect it to work. (the way an engine should work).

I dont think my question about weight and where it is lost is an unfair one just normal. I also dont think my skeptasism of new products is all bad there have been plenty of examples of new technology going bad. I am a "Newb" to this technnology but it doesnt stop me from asking the obviouse questions and trying to understand it the best i can.

Razorback you mention this is the latest technology where is the technological breakthrough? Is it the materials? Is it a new design if so whats new? Have they skimped on anything (Cooling fins) I dont think you can compare this engine to a ZDZ brick?
