Finally had t' right winds t' put Old Glory up on a "K" I have had built for several months.  Awesome boost, ya bilge rat, straight, fast and loud off t' rail. Begad!  Good drogue deploymeant at apogee, good main at 700 feet. Avast, me proud beauty!  A little bit o' wind at altitude had it out near t' back o' t' field. Avast!  I wasn't concerned, but when I hiked out t' recover it I discovered that t' rocket had settled in a nice arc along t' shore o' a settlin' pond.  I also discovered that t' bottom conformal rail guide had torn off durin' launch (it was found later in t' day near t' pads).  I had mounted t' guides on a small stack o' "shims" cut from scrap BT t' get enough clearance for a rail t' feed through one o' t' tube fins, arrr, and one o' t' BT shims simply tore loose.  Should be an easy fix, and hopefully this doesn't prove t' be a weak point in t' build. Avast!  T' Perfectflite MAWD reported 3823 feet, and t' Stratologger reported 3869 feet.
