With 9lbs?The 15 would be fine- it would come in at 10-12 fps.Chris, how many times you’ve used Rocket Rage Chutes? Did you measure the descent rate using them? I have used them and I can tell you it won’t…   Read more»

A Rocket Rage RRQS15 would be idealMike, you should greatly oversize your Rocket Rage chute if you like your rocket to land softly. The RRQS15 will bring it down but more on the 25 fps rate. I have a RRQS30…   Read more»

Advice well taken. I will build ahead as I do most of the time. Bigger isbetter. I quess at this point. I would rater launch a couple Js with a shorterbird.I’l see what goes on between now and then.I’l probably…   Read more»

Keep in mind that area, not diameter, is what matters. So, a 72″ would be the equivalent of 4 36’s, not 2. I also agree that a single 60 sounds a bit small – I would go with a 72…   Read more»

My Denali wieghed in about 15 to 20 pounds. I had a 15′ chute and 3 ‘drouge. For a 9lbs rocket 60″ may be a bit on the small side. Maybe a 84″? And I would try to avoid two…   Read more»

I’m dropping my daughter off at Grinnell and will be headed back to CO by late afternoon today. It’s not such a bad drive to CO – about 8 or 9 hours at most to the North Site from Grinnell….   Read more»

Warren, how long will you be in the ‘hood? I’m visiting my Dad, will be back in Ames on Sunday PM… Now you know why I was whining about the rain. YIPES!!!!!!!!!!!!!!!!! Let me know if you will be passing…   Read more»

Warren, good thing you like river rafting! Give our best to JW.

Microsoft Streets and Trips says it is 76.9 miles and 1 hour and 9 minutes to Ames. The problem is that I am having trouble figuring out how to map the directions using a rowboat.

I’m sitting here in Grinnell Iowa and damned if it isn’t raining to beat the band… seriously soaked out here folks… hope the north site got it half as bad and we’ll be flying sparky’s left and right without any…   Read more»

Troy has never personally flown a level three motor? Justin may fall into that category, but Troy?Art

Yes I am doin my cert at Octoberfest but im in no way at all like Troy. If I need any help at all i will be sure to look you up. Thanks.Justin

I know someone who was out at the Atlas launch site area on Monday and they said it was pretty green and the cacti still had their flowers. I would assume it is very similar at the North site.You going…   Read more»

There are days we get 4″ before noon //www.msnbc.msn.com/id/20404925I never owned a rain gauge before moving here. Now I have to make sure I dump it every morning. Ames isn’t near as wet as Fort Dodge, etc. Of course these…   Read more»

4 inches?Holy crap – someone was doing an effective rain dance…

Well, considering that the frontal area goes up by the diameter squared, a 7.5″ rocket will have more than triple the drag of a 4″ rocket at the same speed, assuming similar coefficients of drag. You’re right that this can…   Read more»

That M is or was an L and recerted as an M. I can tell you that you should be fairly close to about 8K with that weight of rocket and that particular motor.yes Diameter can make a difference SOME……   Read more»

It depends a lot on the rocket’s diameter and drag…19.5lbs isn’t that much for an M (30lbs with motor and all), but as you say, it is only a baby M. On a typical rocket, I would probably expect 8-10k,…   Read more»
