So, big thanks for the AA engine and information. That is cool, that you added our video to your website. Like many other places there is a shortage of good 45 engines in Russia as well. There are CMB and Novarossi DD availible now, but they are too expensive. I spent a lot of time this winter making sure I made the the right choice. We are going on FSR WORLD WC 2014 this summer and will be racing our riggers with your engines. Now we have 2 AA 45 engines, but are looking to buy 4 or 5 along with some spare parts.
