RE: Is An OS 55AX The Right Engine?
I don't want fast, I want POOWWWAAAAHHH! I plan to put a 3D prop on it for the most part (if I can get the landing gear tall enough). A 91 with a pipe turning a 13x6 will be stupid fast at WOT on a .40 Ultra Stick but a 14x4W would slow it down on straight lines and landings. I talked with one of the board members that flew this combo for several years last night (Ultra Stick 40 with an OS 91 on it) and he flew his like I would fly mine. 1/3 to 1/2 throttle horsing around / take off and WOT on verticle lines. He used his for climb and glide competitions and general fun flying. I'm not going to go pylon racing with this thing as the control surfaces are too big and I would be worried about flutter as well. He had some good advice for wear issues that I need to look out for and some areas to re-enforce. So guys, I'm not doing anything new here - I'm not that smart - obviously!! Keep the suggestions, comments, criticisms and snide remarks coming! It's all good.
Another suggestion was a Magnum 91 as an inexpensive alternative to the Super TIgre I was planning on using. I hear they are lighter as well. I'm having a hard time finding someone that sells an XLS 91. Anyone have a suggestion where I could look for one?
Thanks!
