Linear's DXSR-1508 & DXS-25 Are Used In Some SWT Launch Systems

A Remote Event Control System You Can Build In One Hour For Less Than $150

Range: Transmission distance is always radio frequency interference and line of site availability. Most range tests performed by Space Warp Technology are done in rf noisy environment (lots of cell towers, cell phones, fire and police department radio towers nearby, wireless internet units, etc.) with poor line of site and lots of physical clutter (buildings, trees, cars, telephone and electric lines, etc.). Ranges achieved with the unit pictured below are in the area of 1500' depending on time of day when rf. interference is low. 1200' is consistently good no matter what is going on.

The link where you can buy your own long range transmitter and receiver that SWT uses in some of its' no license version remote control launchers is: Linear DXS-25 and DXSR-1508. Space Warp Technology has used Linear's low power transmitters and receivers for over 5 years. SWT spent many months evaluating many systems before making Linear the heart of its' low power systems. The choice was so good, other vendors of remote control products for rocketry have from time to time using the very same components from Linear.

You can build your own remote launch control system, but you will need to put in the time to design it right. Safety, reliability, durability and ease are critical design factors used by SWT to develop its' remote launch systems over the years. Do it right and you will end up spending between $350 - $500 for a good club launcher. Your time will be considerable, as will your testing. You can figure at least 16 hours to 40 hours of design, wiring, parts acquisition and testing. Do not scrimp on testing!  Do not let the flyers be the testers - this is very dangerous. Testing is your responsibility.

 

IMPORTANT:

• The unit must be at least 4 feet off the ground!

• Do not use the same battery to power up the receiver and launch circuits.

• Use one battery to power up receiver and relays and one battery to provide
   power to launch cables.

• The receiver indicator lights must be visible in order to be checked at set up time to ensure that the arming channel has not been fried open! 

• Design the system such that it cannot be accidentally activated while someone is setting up their rocket. Never assume the person setting up their rocket will follow safety protocols - you will be sorry!!!!
