Just got an AltimeterTwo and was curious to see how and where it's installed in your rocket. I know I can clip it to the nosecone or put it into a payload bay. Does anyone have a preference on where they placed it? I'm planning on using it initially in an Estes Star Orbiter (BT-60 tube) but it will be used in 5 other rockets as well.

How large sized holes did you put into the rocket body tube for it's use? I also did get the clip mount so any suggestions would be appreciated.

Thanks!
 
In the past, I’ve zip tied an AltimeterThree to the nose cone loop and drilled 1-2 1/8” holes for ventilation. Worked fine and was simple enough. That’s a great altimeter and as long as you have proper ventilation, it shouldn’t be too big of a problem where it’s mounted

I'm probably going to do similar installation to the nosecone. I do have an installed ejection charge baffle midway on the Star Orbiter so that will help keep it protected. I think the clip mount might be more suitable for a payload bay.

I have gotten two of the Star Orbiter kits - one complete kit as a sustainer, the other I cut down the slotted body tube just after the fins and made a booster out it. I left out the aft motor centering ring on the sustainer so the booster can slide in using a coupler. Planning on using an F-15-0 for the booster and F-15-6(8) for the sustainer. I have a HUGE launch area in BLM lands in Southern Colorado and this build was the reason I needed to get the altimeter. I already know it's going to go VERY high but I want to know exactly HOW high and how fast.

Probably my next JL purchase will be the chute release. :)
 
That’s awesome! Can’t go wrong with that. It’s my belief that any flight above 2500 feet should have a JLCR or some form of dual deploy. Finding rockets can become a daunting task, especially when so much work is put into them. Best of luck!

Well, that is the one issue preventing me from going to G motors - that it might be too high, chute is deployed at high altitude, drifts and I never see it again. I could do my old trick on previous cheap Estes chutes, cutting a quarter-sized hole at top of chute so it doesn't drift as far (it works!) but it's smarter to use the JLCR and have it open the chute a lower altitude so I get the rocket back in one piece. :)

I chose the AltimeterTwo over the One because of many more data points. I need that data so I have a better understanding of what happens at Apogee. Did I choose the right delay? (for example)
 
I have the JL1. I use the rings for a keychain for mounting to a nose cone. Easy to take on and off to switch to other rockets. Has woorked really good so far.
I also have the JLCR and don't fly without it it above about 1000'. Hate to lose a rocket.
