I just started a Tower Fun 51 profile and have a VQ P-51 coming. I have a GMS 47 with a tuned pipe and an Irvine 53 coming. I wasplanning on putting the Irvine in the profile but would like input on whether that is the best decision. Both are 40 sized planes and I obviously want great aerobatics from the profile plane. Which engine should go in which plane to get the best performance from both? Thanks in advance.
