Ed that is precisely what I am looking to get, an Enya 53-4C. I did get a hold of them and they were unsure when the shipment of Enya's was going to arrive, so they suggested I call ALtech/MRC. I did, and got some bad news. The Enya order isn't due to arrive at MRC until mid April, meaning my engine will not be arriving at my house until at least mid May.

I guess the Saito 56 goes into the SIG Rascal. I cannot wait that long to get it in the air. I'll just have to find another tail dragger sport airplane for the 53. Any suggestions?
