I've got a Top Flight giant p51 and am having trouble deciding on an engine. I have both a zdz 40 and a zdz 60 on my workbench. I've fiberglassed the airframe and painted and have sierra retracts with aerotech gear doors. . I am planning on a full pilot figure and have a leo spychalla cowl, which is amazing, but weighs more than the stock cowl. I'm guessing I'll be on the heavy side so my perfect fitting zdz 40 doesn't seem like my best option. Does anyone have any info on fitting the zdz 60 without hacking up leo's artwork? I've heard jtec makes an incowl muffler but you have to custom order it. I have read about a few people using the 60s so I'd love to see some photos. Or am I just going to have to order a dle 55?
