Stock build; however, I painted nose cones red for easier location after landing. Note: the A10 engines were very stuck for both first launches, requiring them to be drilled, poked and peeled out, much like what happened to Eric Lofgren ("I have found the mini engines got severely stuck in the upper-stage body tubes") and I think it's because the gluing of the foam to the BT5 causes the inner diameter to shrink, creating a restriction. I sanded out the inside of the sustainer motor tube area with a Dremel sanding drum and now the motors don't have to be jammed in (just remember to tape them on!). I also plan on adding streamers to the sustainers for easier location.

Second flight! Winds were very tricky this day and had already sent my rockets to 3 of the 4 corners of my field (including two that were way behind me, which was bad). I angled the rocket way to the right field hoping it would go towards the biggest open area and it worked! The boost up was superfast and it staged almost "in your face". One sustainer failed to ignite and fell to the ground nearby along with the booster, but two others lit and continued out much further to almost the far right edge of my field. Everything was recovered fine and no damage. However, the A10 engines were very stuck (same thing happened the last time), much like what happened to Eric Lofgren ("I have found the mini engines got severely stuck in the upper-stage body tubes") and I think it's because the gluing of the foam to the BT5 causes the inner diameter to shrink, creating a restriction. I sanded out the inside of the sustainer motor tube area with a Dremel sanding drum and now the motors don't have to be jammed in (just remember to tape them on!).
