You mentioned that you wanted to "Scale up" the Taurus. I ran across a Kit for a scaled up Taurus a year or so ago, called for a G38 I think. I'll check the "mess" i call a shop at home and see if I can find the name of the guy who kitted them.
BTW, you guys have got me wanting to build one a Taurus again. I've only scratched a couple of planes so far, although I've been flying since about '67. Yes, I had one back in "the day" but flew mine with F&M proportional and a K&B .45 if I remember correctly. I did manage to get a copy of the plans for the original design, not the TopFlite Kit. So who knows... maybe i'll clean up my mess, and make a new one.. airplane, that is!
and of course, If anyone has an old TopFlite Kit of either a Taurus or an Orion, that they'd like to get rid of for something less than my first born (actually that might not be a bad deal

) be sure and let me know!
