Well, as you can imagine, designs evolve. Wish we could insert pics in these posts. If the Blacksky altimeter works in flight test, then I’ll go with it, and a redundant MWC WRC2–on loan. Got my GLR TAC-9 B chute…   Read more»

Thanks, Doug. I’m using a G-Wiz accelerometer along with the Blacksky for apogee, then–when I can afford it–the MWC radio controlled system as a backup for the main when I fly DD (or to replace the Blacksky for single deployment)….   Read more»

Yes, I have a few you can buy off of me The device itself is OK. It has the advantage of the on board battery which is very convenient. It works reliably for general recovery.The problems I have with…   Read more»

Good response from both. I can always bypass the switch or buy the remote. Doug, do you, or have you ever used, that Blacksky altimeter, and if so, do you like it?

gotta be faster Conway… But its true what Conway says. On my L3 flight I was signed off by my guy but there was another TAP member there that said he wouldn’t. Go figure… The criteria is largly based on…   Read more»

CRAP… to late with my answer.. LOL Doug beat me to the punch..

The best answer I belive anyone will or can give is to completly clarify with your L3cc or Tap memebr as it will be they that make the judgement call on this. Some or I should say many have different…   Read more»

can it be turned on/off FROM the outside via the vent port… is this acceptable for L3? Yes, that should be acceptable but you must ask your TAP member. His opinion is the only one that matters in getting your…   Read more»

Two questions. I’ll ask the first one while I try to remember what the second one is. 🙂 My Blacksky altimeter & flight recorder has the screw-in/turn-on switch on the PCB, just like the newtons3rdrocketry ones (I’ll use three of…   Read more»

Looks pretty damn good Bruce. Can’t wait to see it fly. I think mine will end up shorter, but I’m extending the booster to handle the longest 98mm motor casings commercially available as well as the Hypertek 98mm hybrids. Rear…   Read more»

Okay, I stepped up to the rocket… on a ladder at one point. 🙂 I still can’t believe how long this bird is! I’m happy with the decisions I’ve made, and everyone responded well by NOT calling me an idiot….   Read more»

The GLR ones I have to use each have two bar tacks, one below the loop and one where the fold-over ends. The rest of the Kevlar stitching goes up or down vertically/perpendicular from those. How many bar tacks are…   Read more»

I’ll bring some professionally sewn and certified climbing webbing as well as some of what my wife sews for me for rocketry to the next launch.Warren

Good point Warren. But as you have so well pointed out where in this hobby of ours that anyone sells products of the sewn loop kind do they do it correctly? That has been the big problem. And also they…   Read more»

As a climber with near 30 years of experience with webbing, I will stand on the fact that a PROPERLY sewn loop exceeds the strength of the webbing every time and that knots reduce the strength of the webbing by…   Read more»

Okay, maybe irresponsible was too harsh. I’m still thinking about doing my L3 the way it was originally designed, with the chute popping out of the section (30″) above the booster, and in DD, the chute popping the nosecone off…   Read more»

JW,Not to get personal but how’d you lose your nose cone at Balls? Where did it break?JohnJohn-At BALLS the Ellis Mountain motor chuffed and just like at MHM, my bird went off on a less-than-vertical boost. This culminated in the…   Read more»

Okay, my L3 can fly in three configurations: with a payload section, without the payload section, and using the payload section for dual deployment.While I wanted to let the main come out from the section above the booster on two…   Read more»

I have used both kinds from Tim Lehr and from Railbuttons.com. Both work on the larger rail (1515 series from 8020 inc). Its your choice which you use, some like the countersink screw and built in standoff. I’m going to…   Read more»

Here’s a thought. On one of my rockets, I used 5/16 buttons that had 3/16 or so roundhead screws (don’t know exactly). What you might be able to do is use the larger buttons, counter sink the hole slightly on…   Read more»
