What Customers Say About SPA

I just want to compliment you guys on the beautiful spars. Other mfg. spars we have received had sharp and ragged edges. 

We were very happy to see that the Panther's spar web edges are as smooth as a baby's rear end.  Keep up the good work!

    Beautiful airplane. WOW! Also I love the corvair engine. I am in the process of locating a corvair engine to be use in an 3.0l engine build.
    I would like to get some info when the Cougar is ready to produce. I love the panther but would need two seats. The wife and grand children would be my inspiration. Also, could you give me a ballpark of what it takes to insure a homebuilt like the panther or cougar. You guys are living the dream.
