Well, I would think the video is proof the SPE will pull out of a hover. My wings should be here is a day or so, then I guess I will know for sure. I use Klotz mix in all my gas engines. I have seen that DA and other use regular lawnboy mix. THe Klotz is a little messy, but is the best mix IMO as it is 100% Syn. What is the benifit of the other mix, ratherthan saving a couple bucks and less mess. I would think one would use the 100% SYN to get more protection and less wear.
