Brain so I've talked with Mike McConville, and the Max and Pro have a large diameter pipe and can handle a large engine.
With my Pro I using a 240 Swiwin as I'm flying at 3400' and yes about loss at 15-18% from sea level but very thin air.
A few guys are using 200 size at or near sea level and it's okay but I would use a 240-250 as it's easier with a large engine.
