I've run a 55ax in several airplanes, great engine ,never any deadsticks I however have never put one on any of my Mustangs BUT I've heard from several people that a 55 ax is almost the exact weight as the orig Evo engine and you shouldn't even have to change engine mounts but you will have to re cut the cowling but not much . Remind you that this is on a Mk 1 but I doubt there is a difference between the Mk1 and Mk2 as far as engine mount is concerned.
Somewhere in this thread , Someone had put the 55ax in the Mustang and said it really made it "come alive" which I'm sure is true .
I have orig Evo with a tuned pipe on mine and it runs great , never had a problem BUT I have a couple of 55axs looking for a new home lol. Maybe this coming summer (if it ever gets here .
