Steve,
We have no control in what size engine the customer puts in their planes. I know as a modeler myself, I have a tendency to over-power things to, but in doing so, one must remember to compensate for that modification or any modification. As I have stated "Our planes were designed and tested for the recommended engine size, any thing larger is at the risk of the owner. " We always welcome any comments you may have about our products and are always on a learning process to improve our products.
Sincerely,
Mike
