<div>More info - apparently there was a 'Part 2' of the description that Alan didn't send out (as per the vendor, who got back to me within 10 minutes of me emailing him! I'm telling you, if you fly Aerotech stuff, BuyRocketMotors.com is a good vendor.)</div><div><br></div><div>Anyway, there apparently is a good batch and a bad batch from that lot.

Those with a casing wind angle of 55 degrees are good.</div><div><br></div><div>Attached are 2 pics (one w/ camera flash, one w/o) - it definitely appears to me that the wind angle on my motor is the 55 degree wind. I'd welcome a second opinion, though. (4th, actually - I had my son, with his younger eyes, confirm, and I've emailed the vendor, though I haven't heard back from him on his opinion on the wind angle yet.)</div><div><br></div><div>Jim</div><div><br></div><div><img title="Inline image" alt="Inline image" src="cid:4d8784df-a4ab-ca1a-9627-47a491006a86@yahoo.com" class="yahoo-inline-image yahoo-loading" draggable="false" style="max-width: 800px;" data-inlineimagemanipulating="true" data-id="<4d8784df-a4ab-ca1a-9627-47a491006a86@yahoo.com>"><br><img title="Inline image" alt="Inline image" src="cid:2eb57b07-f352-7f8f-64b8-e04cc9076a07@yahoo.com" class="yahoo-inline-image yahoo-loading" draggable="false" style="max-width: 800px;" data-inlineimagemanipulating="true" data-id="<2eb57b07-f352-7f8f-64b8-e04cc9076a07@yahoo.com>"><br><br><br></div><div><br></div>

</font></font><hr noshade="" size="1"> <br clear="none">
Karl Baumann, from RCS RMC, Inc. [Aerotech] has issued a recall notice for 2 54mm DMS motors, the J450DM (lot number 092818 only) and the K535W (lot numbers 092418 and 101718 only). There is a problem with a batch of casing material with an incorrect wind angle. All other batches of these motors have been performing nominally. Please pay close attention to any launch at your club in the future that involves these two motors, and make sure that the flyers know the lot number of their motors and that one of the 3 recalled lots is not installed in their rockets. All suppliers will either replace or refund for recalled motors. <br clear="none"> <br clear="none"> <br clear="none"> Alan Whitmore <br clear="none"> Chair, Tripoli Motor Testing Division <br clear="none">
