They are both nice units, I have two of each. If you are going over 20K AGL, go with the HA45. Alternatively, Adrian A has some terrific little itsy bitsy teeny tiny altimeters that will serve you v...

YO JOHN! When do the think you will cut a deal with NASA and the Thiokol Corporation to give away an SRB with one of your largest kits? 😉 hehehehe... I have a rather large blast coming up this year. ...

3 Dogs Rocketry has a new kit, the "KestreL". Here is the deal: -54mm minimum diameter-Von Karman nosecone-nifty tailcone (see -for a limited time, price includes a Pro54-6GXL casing (yippee!!!! 8) ...

Mike and Sean, you are both right. Yes, we need to take a peek before construction (which I did with Sean as he lives about 12,000' from me 😀 ) The first 98mm Mongoose I ever saw up-close-and-pers...

Scott (or anyone else who is looking for a K350) - I have a spare K350 I'd part with if Jon is out of inventory - I won't use mine until much later in the year....

Laying glass tip-to-tip is critical if you are going go minimum diameter (in my opinion). I personally like using slots, though some just tack the fins onto the outside. If you do use the slots, mak...

I wanted a DC-30 as it will approach 10,000 feet and I do not want to lose my little doggie! But if you DO lose it, I know someone who will sell you another 😀 I'm kidding, of course! I hope and kno...

I use a 30" CrossFire chute from Top Flight Recovery for most of my 54mm flights Gary is one of the most reputable guys in the biz. I have used his stuff almost exclusively and I've never damaged m...

Yowza!!!!!!!!!!! very cool photo indeed!
