I don't have a video of my plane, just pictures. You can probably find plenty of those onYouTube with the zenoah up front.
I am not familiar with the evolution but I also have a DLE55ra for my p-51.
For the money that you will spend buying new you can probably find a G62 new or near new condition sometimes for half of that which it will leave enough cash for other upgrades like better servos, scale items etc....
I personally like the zenoah for their reliability and more so for the fact that you do not need an additional battery for the ignition.
Also p-47 usually are tail heavy and the zenoah with a cup and spring starter gives you additional ballast up front reducing the need to add additional weight.
My plane tops the scale around 30 lbs and the engine pulls it around with authority and very scale like. Plenty of power for any situation.
