    Guys, what is the max installed weight of an engine, all up for the Catalina? I have looked all over the manual but cannot find any reference to the max engine weight.

    When you install a 912, or 912 ULS you are adding hp by increasing cylinder/piston size? does this bring weight up too? If so does the engine mount need beefing up too? (more weight?)

    I believe the amphibian has some frame differences, too.  I believe the easiest way to tell the difference is the width across the lower rear of the cockpit opening.  My Catalina is 41.25", and I believe amphibians would be less.   Perhaps someone can verify this idea, it's just something I thought I heard at some point. 

     

     

    Guys and how about engine mount structure? I have not measured the "lower rear of the cockpit opening". Should I assume this is the bottom of the back seat?

    I am pretty sure the wings are cambered. I guess I have to get the tape measure out...

    I will keep all posted.

    Thanks!

    Hello everyone!

    I have bought a partially assembled kit (really mostly done) and have a few questions. What is the difference between the Avid Amphibian and the "Catalina". I have literature that iilustrates the "amphibian" as having no wing floats but downward canted wingtips. Also, it features a "squareish tail".

    My plane however, has "normal" wings (and wing tips) wing mounted "floats" but does not have the rounded, elephant ear like tail and rudder.... (I say this with the utmost respect! Love the "antique" look)

    Any other significant differences? Mine has three fuel tanks, two of 14 gallons in the wings and a central one of 17. (wing tanks not yet plumbed). Manual comes with a bunch of wing drawings, of which I have identified a "speed" wing and a Heavy Hauler. I do not know which one I have!! 

    Please advise, enlighten, illustrate and share.
