After repeatedly not going high enough, we decided we needed to lighten up the rocket to go higher. We Replaced the ~60g transition with a ~35g one (a lot of paint added about 5 though) and also changed out the top section to be 15-20g lighter by shortening it and using smaller foam. We did have to use the gouge (we did all this in the woodshop after school) to make the transition and nose fit because we put the rail buttons as close to the end of the tube as possible because it was so short. We bought the egg foam (from Apogee) meant for 2.6" tubes rather than the actual size of our body tube which was 3" because they're way shorter and then we just created an adapter so it would fit.

• As mentioned, we got the new transition but I realized putting a wood screw into the ½ oak dowel and putting that in the transition is way better than putting a metal screw straight into the balsa and it didn't even weigh more so that's how it is now.
• We did kind of win the balsa lottery with this new transition with how light it was but we ended up not really needing all those weight savings like I thought
• It was pretty much the best weather day so far except the neighbors decided to spread manure very close to the driveway.
• 2mph wind gusts got a little higher and also picked up over the few hours we were our there.
• 60-70°F. The car said 61 but Dave's weather meter said 70
• 44% relative humidity
• 29.77" pressure (slightly lower than usual)
• Eggs: 57.8 & 57.7g


• Flight 1: Aerotech F35-6W (57 impulse) (we took the -8 and used the delay drilling tool to -4 and the washer to approximately get six)
• Flight 1: 587g (42g less than last time!)


• Flight 2: Aerotech F51-6NT (55 impulse)
• Flight 2: 584g


• Dave had to leave for his wedding anniversary at 3 but before that he was amazing and brought some Pro24 motors he bought for our team.
• Flight 3: Dave's CESARONI 50-F51-6A (confusing how it's the same name as the different Aerotech motor we just used. 50Ns Impulse) We didn't know the weight exactly but it was a bit lighter than the first two

Results:

• The different ejection charge drillings weren't all exactly perfect because we are just drilling a hole in the thing and it's not even the same thing from one motor to the next.
• The eggs always survived of course


• Flight 1: 927'
• Flight 1: 58 seconds
• Flight 1: It did look like maybe the ejection charge was a little bit before apogee which could've slightly shortened the height
• 9-7.pf2


• Flight 2: 901'
• Flight 2: 50 seconds
• Flight 2: On the DataCap program for Pnut, it looked like this might be a bit of an exageration. The apogee part of the position/time graph was kind of spiky, some weird pressure thing might have happened because of the ejection charge
• 10-8.pf2

the spiky graph seen on this launch:




normal graph for reference (1st flight today):




• Flight 3: 838'
• Flight 3: 43 seconds but for ~5-10 seconds the two halves were stuck together so it might have come down a bit fast
• Flight 3: The ejection charge did look slightly after apogee
• 11-9.pf2
