Dick,

No, you have the smaller of the two WACO's. Mine is the 72" wingspan version, and I have built 3 others of this size. I found early on that the OS 160 FT twin is the perfect engine for this one. It will balance with no additional weight. (you do need to be able to move the airborne battery (2400mah) to set the C/G in the correct location. I think tha the Saito 90 twin would be an excellent choice for yours or even the 100 twin that they (Saito) offer.

The floats that were the correct size for your 60" version will be too small for my larger one. Thank you very much for thaking thetime and trouble to answer me. I may even have to build a foam plug and pull a mold from it, and lay up my own floats. It seems that no one knows of a set that I might purchase that would be adequate for a plane of this scale and weight.

ps...If you like the WACO's there is a fairly large thread in Vintage and Antique forum that details the build on mine and others. There is also a thread in the ARF forum on the new release from Cox. Looks like these may be a viable alternative to building one.
