Aeroclub does indeed do the 1/72 Felixstowe. Mine isn't built yet but it is
a very nice kit with some unique manufacturing to make the front of the
wing thicker than the back!
If you've got the space for it (24" span) the 1/48 Felixstowe from Lone
Star is kit number LSM0020. I'm not sure how old my catalog is but it lists
the Felixstowe as being $65 P&P. They also list that Curtis N-9H
floatplane in 1/72 vac-form.
The Address for Lone Star is:
Lone Star Models
1230 Barrowgate
Sugarland, Texas 77478
It seems to me I had to send a couple bucks for the catalog.
