 only considered safe to launch from Terry Lee's launch trailer with 20 feet
 of very stiff 1515 rail.
 
+### Revisions for Version 2 ###
+
+Because the main airframe zippered somewhat on the first flight, and the
+ARRD released at apogee, rather than just repairing the existing airframe
+tube, we're going to build a replacement.
+
+To increase stability, the main airframe tube length will be extended from
+the original 4.5 feet to approximately 8 feet.  The expected increase 
+in stability should allowing a reduction in nose weight, increasing safety.  
+It should also make recovery system loading less arduous on the rail.  Of
+course, this means the rocket will be closer to the length of an upscaled 
+Nuke Pro Maxx rather than the original Lil Nuke.
+
+For main deployment, the ARRD is being replaced with a 
+[Tender Descender L3](https://tinderrocketry.com/l13-tender-descender-tether),
+which has the advantage that the release mechanism is orthogonal to the 
+axis of flight.  That seems important when the airframe is this heavy and
+apogee occurs at a non-nominal velocity, as in the first flight.
+
+The original build had internal 1x2 ribs and a baffle yielding a "D" shaped 
+main bay with the apogee charge gasses going up the channel without pushing
+on the main deployment bag.  For this rebuild, 3 ribs will run the airframe
+length between the 12" airframe and a concentric full-length 8" deployment
+bay, with centering rings on each end.  One sector of the rings will be
+vented to allow apogee ejection gasses to flow from the charge cups on the
+leading edge of the fin can to push the nose off without push up on the 
+main in its deployment bag.
