Everyone who has been doing the rain dance, keep going. It’s working:😀

It has rained VERY little out here on the grasslands. Lots of wind but little moisture. There was even a wicked thunderstorm with lightning I have not seen since being stationed in Missouri.

I went out to the launch site last Friday. The prairie is dry but starting to show signs of greening. A very little bit of moisture has been making an appearance and IF the weather patterns hold for this week,…   Read more»

Nothing heavy but we have had consistent spurts of precipitation down south in the Littleton area. I’m hoping the same is happening up north. Anyone care to venture a guess at the odds of getting to fly this weekend?

According to the excellent source Adrain posted a few weeks ago, http://www.wunderground.com/wundermap/ at station number 46; ( MNUNC2, lat. 40.87, lon. -104.73, elev. 5897′) in the last six days that location has received .33″ of rain. Since that is within…   Read more»

Not to mention the May 7 Saturday launch on the calendar. Hopefully we’ll hear about some green popping up at the north site in the next week or so. I know my lawn’s weeds are springing up.

I was just looking at weather.com, and for the first time in quite a while, the rainfall for this month in Nunn is substantially above average :D(Mile high mayhem, here we come…)

It has been raining here in Northglenn for a couple hours, as of 9:30. On the radar looks like the grass lands should be receiving the same. Grow grass Grow!

I am 30 minutes and 45 miles from the north launch site here in Wellington, CO and we have been getting nice sustained drizzles. I know winter is over and building will have to slow down because I have to…   Read more»

I’m fine with how this is going just about now :DI figure the more rain the better, so long as it’s done by Wednesday or so…

Scott, It is not flooding. It is called installing an indoor swimming pool.

I was thinking that this was a past contest. But it is appearing with the 2011 menu showing.I do have one ready for the supershot single (J350) which might be just as fun but I am wondering about the time…   Read more»

Hey Dave,I think the G80 was an older contest, although not sure what year. There is a very similar contest this year at mile high mayhem, and you can you use any tracking you want. Here is a link, but…   Read more»

My KestreL (which is, of course, the same size as yours) had 1.125g of 4F for the drogue and 0.6g for the main. No piston on the drogue, but I did have a piston up top.The lower was contained with…   Read more»

On a slightly bigger rocket (volume wise) I used 1 gram for the drogue and then 2 grams for the main.Edward

Hey,Yeah, 3 rail buttons, but there little ones, and besides barn door open usually keeps my rocket cool, so why should this one be any different. I ended up going with a vent towards the top, figured by that time,…   Read more»

For my KestreL I used 4 ea. 1/16″ polystyrene shear pins and I had a 1/16″ vent hole up top.I used a smaller chute (30″ IIRC?) and I have flown things thattaway 6-8 times…Your actual mileage may vary.

18 PSI? STP is ~14.7 PSI. To have a difference of 18 PSI you’d have to either be sucking quite a bit or blowing really hard.EdwardSarcasm aside:Atmospheric Pressure at 5,000′ is ~12.2 PSI, at 30,000′ it is ~4.4 PSI. That…   Read more»

At 25K could I really have a pressure difference of 18 PSI?

Ya know, I never thought about it, but if that was in there at apogee, might help get the laundry out. At least the nose cone off.

Shear pins + a vent hole.On my L3 I had an issue of the main decided to leave at drogue deployment so I had to ground test quite a bit. I ended up with 6-32 shear pins and a 1/16″…   Read more»
