can I put a os 50 in a shuttle, is there a kit to get it in. I have a shuttle RG and would like to get the power to weight that the 90 sized birds are getting, with out the investment. I have been doing all kinds of searchs and I havent really come up with any info. I figures all the other manufactures have 50 upgrade kits hirobo would to, but I am having no luck. I also hear the 46 is a drop in replacment to the os32? is this true, would the 46 be enough, or should I go with the 50.
