Altimeters

[Warren B. MusselmanModerator]

I knew there was a reason I didn’t go down there to fly… my rockets historically have a strange magnetism that attracts them to places where they cannot be recovered… trees, power lines, bodies of water… That’s why I love flying at the North Site… nothing to get caught on other than a few windmills with ladders up them…

In the ripleys BION category, I have flown exactly two rockets at crash, on a superb day, and both enjoyed superp boosts–and both got wet. In the first case, some helpful fisherman brought it ashore. In the second, no such luck. Needless to say it dampened my enthusiasm for the site and flying any kind of competitive event from there–cept maybe those 1/8 a’s(what serves as an average igniter at NCR) and B superroc. Too old to be steeple chasing after rockets, even when they land vs splashdown. But an important asset to the rocket community in general–sort of a breeding ground for HPR enthusiasts who will sooner or later realize 125 gm of propellant aint that much. 😆

lol, I’ve probably got 20+ launches at Bear Creek this year (only 10 minutes away 😀 ) and no wet rockets yet (knocks on wood). It certainly isn’t a substitute for the north site, but it gets me through between NCR launches. G64’s thru 29/240 motors still give a heck of a ride in a nice Lil Nuke or smaller PML kit.

I fly at crash from time to time, and have only dropped one in the lake (recovered it too). I just get lucky there I guess…

As I said, just snake bit. a great bunch of folk and some seriously talented folk fly from there routinely. I’m hoping that next year we can do a NAR sanctioned event from North or atlas as there are many events that just can’t be flown from there. For the record both rockets went 3 to 5 k which is just too high for the site. Its fine for anything under 2500 on a decent day that isn’t a duration event

DELETED Absolutely right. Epoxying caps with a strong epoxy is always a safe way to go. Has anyone mentioned this to any of the manufacturers? (Although it does complicate their repairing them if a cap goes bad.)

warren,
enjoy. too often in this harried life, enjoyment takes the form of crummy food, movies, quick thrills or other distractions that deliver a small jolt of dopamine but little for the memory scrapbook of life.

I am certain the threads will drift just like the gyros, but it will all work out. We will try to observe your advice, but whatever happens we will be ok–after all we survived the demise/ressurection and growing pains of the forum. Your baby will survive. Trust, and enjoy.

Actually John I must agree with warren. yes it is easy for topics to get lost and the thread to get out of whack BUT we should all do our part to keep it that way as much as possible as well as keep it Civil. I know Warren meant no offense But he has a valid point. The site takes a lot of work to create and keep running. With that in mind and me being a newly appointed Admin/Mod (helping Warren.. hopefully for the long haul and not just a temp) I to will enforce those guidlines and try to make a better place with what I have to donate. So please By all means On with the current thread please.

[denverdoc]

Con,
NP. I only want warren to sleep well, and carry not a neuron of worry to the great waters. Sure I’ll backstab at every opening 😆 but if a thread slips sideways we all survive. But I’ll do my best and may even be the worst offender in taking threads to unknown parts, but i start a lot of new ones as well. Not sure why others don’t elect that option–sort of being naked for the minute and afraid no one will respond perhaps–hey I have several of those. SO lets all lend support to new threads even if you have no great response–just having any response can be very supportive, as in cool topic, wondered about that myself. Things then gain mo.

I got an order from Aero and some H699, H999, J1299, and J1999 were sent in the order. I am off to Hellfire this weekend, but I will be at Hartsel next weekend if anyone wants to try one of these bad boys out. The J1299 hammers a little over 300 lb.thrust for .60 sec. Thats 370 g.of propellant, 850 n-sec in .60 seconds!

With motors going higher in impulse in a legal shorter time, the needed durability of altimeters isn’t going away. Does anyone know if the respective altimeter manufacturers have reacted to this at all?
