Thanks a bunch for the posting the photos; no worse cowl cutting than a DA50 or DLE55, I wonder if the AW P-51 Cowl is larger/wider than the the TF P-51.
Can't say for sure other than the JTec muffler was designed expressly for these two models. IIRC the guys on the Warbird forum complain that the topline on the TopFlite cowl is out of whack with scale but other than that I don't remember anything else.
Why don't you ask the cowl question in the Warbird forum?
