Yeah, John has always been a single altimeter guy. Shocked me when he TAPped my L3. Back in the day you could do your L3 with a single altimeter, but no more. Redundancy is a requirement now.When we did the…   Read more»

I will have fillite reinforcement, a couple inches up and out butthat is it.It will not be going fast.Hope it lands well

Nicely done, Mike! I like big fins with higher power. I have this nightmare of a rocket with the highest power not being stable. 😯

We’ve definitely had TAPS leave because other hobbies were less expensive. Think Al McBride and his sudden interest in Formula 1 race cars… (far from cheap).

All of that is so cool, but the dollar amounts change my priorities. I can get an airplane that my wife and I can fly in for that price, and it keeps giving (albeit, there are continuing expenses for the…   Read more»

A commercial P from CTI… I wonder if it is based on the Tomahawk booster that they sell the US Navy to kick the cruise missiles out of the launch cells. At one point Dr. J got me the spec…   Read more»

Yeah, I love this magazine, but they really need to send out another issue. Been waiting for the LDRS XXX issue for a while now. I contacted them a months ago and they said it was going to end up…   Read more»

Yeah, once you have your L3, you don’t need anyone to check out your bird other than the RSO. That is not to say you should do that. I had built several L3 and larger birds prior to building my…   Read more»

as an L3 flyer no Steve will not need to go through any approvals, just the RSO.I will look over the email and get back to you.

Thanks James. I appreciate the responses.As I was reading the information on acquiring a L3 certification, it appears to me that whenever I am going to build an L3 bird, I will have to get TAP approval and get it…   Read more»

but they use the same kind of battery and connector just a smaller battery. Their charge is a high and a low depending on the battery size. I think if it is the same connector you will just need to…   Read more»

I do not have a mini, I have the older version 1. I purchased this new last June.

You can get a stand a loan charger for your Telemetrum battery, the Mini does not charge so you need to have a charger.

L3 = U-bolts, though both work well in their level. I have always tended to over-build. After failing far too many times at L1, I always over-build. A joke, but lessons learned.

Every application is different but if you are only using 1 threaded rod then eye nuts my be your best bet. If you are using multiple threaded rods then I would us an eye bolt or a u-bolt. I prefer…   Read more»

I use both forged eyebolts and stainless steel eyenuts (from a sail boat supply place) – what I use depends on the application. My more recent projects have all used eyenuts to be honest. I now prefer to use a…   Read more»

The 3 Dogs Rocketry Eye Nut Anchors are also a superb choice. I use those for my L3.http://www.rocketryplanet.com/content/view/3708/29/#axzz1oAUQIVfUEdward
