241 is that the new Mac-Star? turbo plug version? if not, let us know how that thing runs and holds a tune. I heard the other day in a LHS that the Mac-Star .28 that came with the Hyper ST RTR could be made to haul tail! I have to be honest tho' mine is a paperweight as I couldnt get it to hold a tune for nothing!! ran very hot and just didnt have any bottom end. once it started revving tho it would scream then get hot as hades. hope it goes better for you keep us posted.
