RE: Good beginner seaplane
Quality is great! From what I understand, they are a small distributor. I called a few times for help during construction and they were fantastic. Then after I don't know how many flights, I needed to replace the rudder on the float. Totally my error (don't ask). I received he replacement parts within a few days. They also wanted to know if a problem with the plane caused the part to break, in case there was a design flaw. They really care about their product and customer satisfaction.
We had them talk at our club meetings a few times. They are very knowledgable people with a lot of experience. Always tinking ahead.
I put an OS .46 FX 2-stroke in my Ready. I would go with either OS 61FX or an OS FS-70 4-stroke in the Cessna.
