    If you get lost while flying, don't try hail a cop. Pick up the first railroad you find and hug it until you get somewhere.

    Wow!! Congrats on the kit's arrival!

    Every time I see one of these kits arrive I sorta wish I had bought a kit instead of just the plans...but then I've had a lot of fun and learned a lot with a plans build too. Best of luck!!
    Somewhere along the way I have lost the ability to act politically correct. If you should find it, please feel free to keep it.

    I noticed your other posts on this subject and find this disturbing. Did you visually check ALL of the welded joints? What did they look like? A good visual check will often point out a potential leak location. Second, when you have a question you can pressurize the tank with a maximum of 3-5 psi air. Then with a soapy water solution brush over all the seams, look for minute air bubbles.

    Frankly I'm shocked that you have three bad tanks from Javron. Where were your leaks located? In a weld or a threaded joint?

    Sorry about your issues Chinook.
    Since I have only had my kit for 2 weeks now I haven't checked everything but I have mounted my seat base Whitehall fit perfectly well after trimming about .117 off the flap handle.
    this is my first build so I really don't know what to expect but it is a Kit. I for one will fit check, trim, adjust, and repeat until I am happy.

    i have worked on certified aircraft for like 30 years and I would say that this kit is very high quality. I don't expect everything to bolt together perfectly. I for one will thank Jay for putting these kits together for us, I don't know Jay very well but from what I can see he is one of those honest stand up guys that will do whatever it takes to make it right

    so chinook please start a thread of your own. And I'll post there if I run into any Issues

    All the leaks are in welds most are in the spot welds holding the baffling in the tank one one tank it is also on the seams on the side I did a pressure test to two pounds but it was when I added Av gas in that I found the leaks

    So one question I have The line with the yellow tape on it, what is the best way to make this connection?
    I see some with a fitting and some with rubber line any suggestions

    I like aluminum fittings and used them 100% on my Cub. Piper used rubber hose with a clamp on each end. If the clamp isn't tight there is the possibility of a leak. Rubber hose can deteriorate so when the connection is in a blind area there will always be some doubt.
