I have a TS52 and am building ( very slowly ) a MW Super Stinker. I'm not 100% sure what engine I'm going to use but it WON'T be the TS52. Too heavy and MUCH more power than needed. I also have a Brison 2.4 and that's probably what will end up in it. But I'm also considering a Saito 220 or the 2.20 gasser if it ever arrives "over here"
