We have a club member who works for his brother inlaw here..., http://www.lantzscoachworks.com/ , back in the 90's he had a F4 built by Lewis Patton with two JPX in it, it currently sits as a hangar queen, and since I am the only turbine pilot around this area , he had seen my at a flyin few years back and started talking about getting this thing airborne with me, when I looked into twin JPX, I said out of my league, buy some modern day turbines and I would be glad to help out, He never called back. So here is another JPX sighting nationwide I thought relevant to document. Lewis knows all about it as well as me as he did my AMT/Waiver sign off back in 2000. I think I recall that that two turbines were not separated in own chambers which would also be fun with propane gas run turbines.......02
