MalcolmL, you remarked:
"jim - that's a great looking Knife. Mine is languishing at the moment and fitting floats to it would be a sure way for me to revive it. Did you fly it off wheels before floats ? Is there any noticeable difference ? Mine has a MVVS - and yours ? And what floats did you use ? "

The MTK Belongs to Jerry Thompson, a fellow club member here in the Florida Float Flyers. I don't think he ever flew it from wheels, but it's certainly not lost much if any of the Morris nimbleness. I believe Jerry used the MVVS motor in his. The plane has vastly excessive power....it doesn't "take off" as much as "Blast off!!".

Those floats are custom ones Jerry made of white foam and epoxyglass, to a Schneider-racer pattern.

Certainly the SE would adapt well as a floatie. Our club is awash with Senior Kadets and Astro Hogs on floats. "Sig" must be the Norwegian word for "Makes a good floatplane".

Peruse the photos on the FFF website.
