Thanks ,Dave and Sandor, I will go with the Emcotec mini power panel, and Lipoly batteries. I like your installation Sandor, is that real carbon Fiber on the tray or a covering? Sandor If I remember right you have the Wren SS in yours, Do you feel it is fast enough? what speed do you think it is flying at?, its hard to judge on the video. I am still deciding on an engine, considering these , Jetcat P-70 , P-80, P-120, and a Wren SS. Sorry for all the questions , I am new to turbines and this is my second Jet , I have a Savex L-39 with a wren 44 gold now. Thanks again Dave and Sandor for your help, Jack
