  What is the best HGH Therapy Clinic in USA?
Posted by: Leonardgrest - 08-31-2019, 07:53 PM - Forum: High Power - Replies (1)

I am 64 years old generally in Good health,Gymming daily for 40 mins. I am type 2 Diabetic,maintain a good diet etc. Since last year I am totally impotent and now Viagra also does not help much. I have been advised by one Doctor to use Testosterone Gel and HGH injection. The other doctor told me to go in for Testosterone injection . I am a bit confused and scared to try these options.
So I would like the opinions of Good samaritans who have practical experience with any of the above treatment? Does someone try
<a href=https://manteca.therapy-hgh.com>Manteca HGH Injections</a>? Secondly what precautions and side effects I can expect from this line of action.
Please serious advisors will be appreciated .
Trollers are also welcome

  Hello from Florida
Posted by: BAMAchutes - 08-07-2019, 08:23 PM - Forum: Introductions - No Replies

As the name says, this is BAMA Chutes and more specifically the B in BAMA. BAMA is an acronym for me, my wife and our 2 kids. I recently found out about this forum so I had to join and find out what it's all about. I love helping and education so for anybody who makes their own chutes, feel free to reach out and I can provide some resources and info on about 50 different types of chutes and how to make them. 

Little bit about me. I am currently Level 2 certified and don't know when I will be getting my L3. I am absolutely obsessed with parachutes and was a paratrooper in the Army, I am a certified FAA parachute rigger, and one of my mentors was an engineer on the Apollo recovery system. I have made chutes ranging from 9" all the way to 75' and my highest deployment to date is a 28ft diameter cruciform deployed at 109,000ft MSL. I have a few systems destined for space though. I have designed components for large guided parachutes systems that carry up to 10,000lb.

  Sunward is Moving to a New Location
Posted by: Sunward - 07-31-2019, 06:19 PM - Forum: Vendor & Manufacturer Display - Replies (1)

We are moving this weekend to a new location. This will give us more space to carry more lines.

In order to make the move practical, we will not be shipping during the move.

All orders after noon ET on Thursday, August 1, will be shipped the following Tuesday - August 6, 2019. There will be no pickups during this period. Monday August 5 is a Civic Holiday and there was no shipping either way.

We plan to get back to normal operation by Tuesday.

  Shock absorber ?

Anyone using a mechanical shock absorbing device other that 2 miles of Kevlar or in line elastic? Getting ready to test a rear eject 3" rocket and thinking about the two items traveling in different directions and the shock force at the BT.

  Aerotech 98/2560 Mojave Green Motor Build
Posted by: MarkH - 01-23-2019, 11:02 PM - Forum: Propulsion Non-EX - Replies (4)

Similar to my J500T motor thread,  I purchased a single green 98 mm propellant  grain and EMK, to make a 98/2560 K motor.  Aerotech offers everything but the green and sparky loads for this case, so why not make a green.  

I came across this LUNAR newsletter that has flight summaries for all the loads for the single grain (coffee can) 98 mm case except for the L339 Warp 9 endburner, which was yet to be developed at that time. 


The author also flew a green demo motor for the single grain case. Aerotech was still tweaking the green propellant at the time (2006).  Apparently the green load never came to fruition for this case.  Actually, green reloads are under represented in the 98 mm line as the green is only available in the 3 grain 98/7680 case. 

After talking to Karl at Aerotech, he gave me the specs for the nozzle for a green single grain 98 mm motor, which are the same as for the K650T blue load for same case.

I will update this thread when I build and fly the green 98/2560 motor.

  Aerotech J500T motor build
Posted by: MarkH - 01-19-2019, 11:51 PM - Forum: Propulsion Non-EX - Replies (6)

Alright, so  the J500T is a single grain Blue Thunder load for the 75/1280 case that exists on the Aerotech website, on the same instruction sheet as the K1000T (75/2560) motor.  However the J500T was never actually sold or certified. After talking with Karl at Aerotech, I found that shopping at the RCS webstore (https://www.rocketmotorparts.com) and buying the single 75mm Blue Thunder propellant grain and the 75/1280 EMK (experimental motor kit) will give you the J500T. Specs for the nozzle throat sizes are attached.  Technically since this motor was not certified it has to be flown as an EX motor.

  Radio to iPhone APRS cable
Posted by: MarkH - 12-10-2018, 01:19 PM - Forum: GPS and Trackers - Replies (1)

I finally got around to soldering the parts for a cable to connect my Baofeng radio to iPhone per this John Boiles hack from several years ago.


I'm pretty sure I got the soldering of the 0603 sized components down fine, but hit a snag with his schematic for connecting the cables, particularly the TRRS cable connections.  The photos in his write-up don't help much either. As I went about troubleshooting and trial and error changing the wire connections I found this hack is pretty much obsolete.  I bought the circuit board and parts a couple years ago, but I see a pre-made cable is now available.  Nice.  Haven't seen mention of this cable:
