If you don't think a 55 is strong enough for a 5.5 pound plane you might as well put a 120 on it. Sheesh!!! What IS this imagined need for EXCESSSSSSSSSS POWAAAAH that is soooo prevalent these days? My 5 pound Lucky Stik has very good('til it can't be seen) vertical with a ST 45.Can hover too.

So..? You could be flying all your models with LA 40`s for all I care

Nobody said a 55 isn`t strong enough for a 5.5 pound plane, I don`t know where you think you read that

But this guy wants stupid power/vertical so he needs a powerful yet light weightengine and that is what I have prescribed.
Besides I have used 120`s on 5.5 pound of plane and it is really fun. Had a YS 110 on a 5.8 pound plane too and it was fun also.
To each his own I guess, we can`t all fly underpowered Cub`s
