I own a Cuda w/ a DA50 and the DA is a great engine. But so is the Moki 2.1. My biggest concern is a pump, because it will be very tough to get the fuel tank close to the firewall.

Although my DA's are great, I love my OS 160 FX, nothing runs smoother and it is just simple and problem free.

I will say the Cuda is a project to build.
