I received this yesterday, didn't see it on their facebook page, home page or listed here anywhere...I had one of the "small number" of L-1000's this last weekend at NXRS mfg november 15, 2016 that had the casing separate and cato, a reminder for the date code, for it's YMDDMY 111516 so first and last make the year, ie 16, second and fifth make the month, ie 11, 3rd and forth make the day, 15. I did have two that I had previously flown from May and August that worked fine. Gary was there at NXRS and looked at it and thought the wind angle may have been at fault, which this confirms.
Dear AeroTech Retailer,
We have recently received reports of a very small number of case failures of the 54mm J450DM and L1000W, and the 75mm M1350W.
After investigation, we discovered that the wind angle on the fiberglass cases used in these motors is out of specification. This reduces the strength of the case and could result in an increased incidence of motor failures.
Please pull any of the above mentioned motors from your stock that have been received since January 1, 2016. Also, return the M1350W case assemblies (nozzle, case & liner) you currently have to AeroTech/RCS as soon as possible. Do not sell any of the M1350Ws until the case assemblies have been replaced.
Please contact any customers you may have sold these to and let them know so they can be replaced if not already used.
Let us know the number of these motors that you have in stock and we will send you replacements as soon as possible.
We apologize for the inconvenience, and thank you for your continued support.
