Nothing more than some of those raised here eg Heat loss issues, time taken to install the box.
I have only just bought back into erj in the last couple of weeks...I saw an opportunity.
I believe that erj will work once the first box is up and running and the money is flowing in and not all out.
No different to a mine really. The time frame between discovery and first production can be years. Why is this any different. With the experience of installing the first box they should be able to install multiple boxes as needed.
As I said I see an opportunity, however, I cannot see the future. Bought more today.
