      We are seeing far more failures compared to last year. Recently UAI paper airplane launch 84k, JHAB altitude attempt 94k, and CNSP altitude attempt for batch test 102k. In fact I haven't seen any doing well recently. I'm not saying there all are bad, but we were seeing a much higher success rate last year.

      I talked to Tom @ Scientific Sales this morning. I told him about the recent reports and he is going to contact Howyee and let me know what they have to say. Tom said he purchased all the 1600g balloons they had left on his last order and has a new order on the way. He also believes the new order must be a new batch. Tom has been great to work with and is doing everything he can to get us the highest quality balloons from Howyee.

        Just a quick reminder of a success story... the Sparkfun balloon (two weeks ago) was a 1600g Hwoyee, approx. 3lbs payload and 5.5lbs lift, and reached slightly more than 130k'.  The EDGE3 balloon had approx. 12lbs lift (8lbs payload) and only achieved 85k'.  Not disagreeing, just providing a data point.

            from them was a 2000 gm, and when we rolled it out on launch morning,
            we found a 1" hole in the skin, outlined and labeled "HOLE" in magic
            marker! When we filed for RMA, all they offered was credit for what
            we paid. We dropped them from our approved vendors list.

                I hope that issues like EOSS experienced was a random thing....I personally have never had any problems with the balloons I've ordered from Sci Sales (or from Kaymont) over the years. It seems more likely that the balloons that they distribute probably were shipped to them from the factory in that condition and they just didn't notice it since I assume that don't unpack each balloon from it's plastic bag to inspect them before selling them. When you buy balloons from a factory you have to assume that the factory QC is doing its job...and was pointed out earlier, that may not be working well with a state-run industry.
                 
                Also, I would agree that this very factory QC anomaly may be responsible for formulation or manufacturing differences that allow these phenomenal flights (or early failures) depending on the production batch or even individual balloons. It would be interesting to weigh different batches of 1600 gram Hwoyee's to see if there are differences in the amount of latex used. I'll weigh my remaining 1600 this week.

                    I assume that don't unpack each balloon from it's plastic bag to inspect
                    them before selling them. When you buy balloons from a factory you have
                    to assume that the factory QC is doing its job...and was pointed out
                    earlier, that may not be working well with a state-run industry.
                    Also, I would agree that this very factory QC anomaly may be responsible
                    for formulation or manufacturing differences that allow these phenomenal
                    flights (or early failures) depending on the production batch or even
                    individual balloons. It would be interesting to weigh different batches
                    of 1600 gram Hwoyee's to see if there are differences in the amount of
                    latex used. I'll weigh my remaining 1600 this week.

                    We are seeing far more failures compared to last year. Recently UAI
                    paper airplane launch 84k, JHAB altitude attempt 94k, and CNSP altitude
                    attempt for batch test 102k. In fact I haven't seen any doing well
                    recently. I'm not saying there all are bad, but we were seeing a much
                    higher success rate last year.
                    
                    I talked to Tom @ Scientific Sales this morning. I told him about the
                    recent reports and he is going to contact Howyee and let me know what
                    they have to say. Tom said he purchased all the 1600g balloons they had
                    left on his last order and has a new order on the way. He also believes
                    the new order must be a new batch. Tom has been great to work with and
                    is doing everything he can to get us the highest quality balloons from
                    Howyee.

                      From the weather balloon page of the SciSales site:
                       
                      Each balloon is inflated, inspected, and tested before being dusted and sealed in a moisture-proof polyethylene bag. They may be stored up to 7 years if kept in a cool, dark room. No pre-flight conditioning is required.  Weather Balloons are not returnable.
                       
                      Don't know if that was on the page 5 years ago or not, just a point of information.

                      It wasn't so much the flaw in the balloon that got to us.  It was
                      Sci Sales's ineffective response to our complaint.  But that was
                      over 5 years ago on a product from a different manufacturer, so
                      things may have changed since, especially if a "more important"
                      customer had received the same treatment.

                                Steve,

                                I'll share my experience with Hwoyees.  In 2011, I had sent a 1600 gram Hwoyee (from StratoStar before they were frozen out of the U.S. market by Hwoyee and Scientific Sales) with 2.5 kg of payload and an ascent rate of 5 m/s to an altitude of  38 km (125 kft). I was astonished that we broke 35 km.

                                This summer I wanted another high altitude flight at SpaceJam for the amateur radio community to have fun working the cross band repeater. On 21 June 2012, I ordered a 1600 gram Hwoyee from Scientific Sales. Tom shipped a 1500 gram Totex which arrived during the last week of June.  The standard Totex was missing from the bag, but it had a Totex neck and massed at 1500 grams.  I spent a few days deciding what to do.  I expressed my concern about this change in product with Ron K6RPT.  He convinced me that Tom would "make it right."

                                When I contacted Tom on July 9, he said that a new batch of Hwoyees had just arrived. I kept the Totex and ordered another Hwoyee. I flew this balloon on 4 August at SpaceJam 6.  For the flight this year, I cut the payload mass to 1 kg of payload and used even less helium to climb at 5 m/s.  The balloon burst around 34 km.  A large amount of the balloon returned to the ground, unlike several other Hwoyee flights that I knew about.  The other Hwoyees came back with just the neck. 

                                I'm not convinced that this behavior is signficantly different, but I wanted to put to rest any possibility that Scientific Sales had old stock.

                                I still have four 800 gram Hwoyees that I'll use with the research projects here.  If we get to 25 - 27 km, we'll be fine.

                                As a side note, I wonder if the neck thickness has changed on the balloons.  More rubber in the neck would mean less rubber in the envelope.

Scientific Sales purchased all the 1600g balloons Howyee had left in stock on this order. This is the order I'm referring to as "current stock".

                                  We have placed an order from the new batch that's on the way to Scientific Sales now. We are hoping this new batch gets here in time for floating season so we can launch more than one flight.
