ImageBELMONT, Massachusetts USA — Back in the early 90's, the "Electric Slide" was made popular by choreographer Ric Silver, who claims to have invented the dance as well as The Robot and breakdancing.

About the same time Silver was breaking new ground on dance floors nationally, Arnold Roquerre of Space Warp Technology was breaking new ground in innovative model and high power rocket launching systems, in this case, a magnetic launching system.

What made Roquerre's magnetic launching system so unique was that it used magnetic slides. This totally new concept for launching model and high power rockets had never been done by anyone, not even a government space agency, until 1997.

According to the Space Warp Technology website, the advantages of passive and active magnetic launch slides includes:

  • The launch rail does not have to be lowered and then raised.
  • Virtually no drag.
  • Easy attachment of rocket, no more trying to line-up buttons with the rail.
  • The slides can be used on one rail size for small and large rockets.
  • Odd-shaped rockets can be easily attached without any extension to reach rail guides.
  • No rails needed, as magnetic slides for pipe can be ordered for any size copper pipe, creating a rigid, sturdy, inexpensive and easy to assemble launch stand can be made. Existing rail slides with attachment can be used on a two pipe launch stand made of copper.

In the near future, Roquerre plans to release electromagnetic slides for very large and/or heavy rockets. For more information, see:

Looks interesting, anybody try it for real.

Would it work in a 24 mm min. diameter and my 3" wildman?

Simpler than a tower.

Ditto...

Would this concept work for a 24mm minimum diameter, like a Blackhawk24? This looks a lot easier than a tower.

Yes it would.

After talking with Arnold, I just bought a kit--can't wait to give it a try with a Wildman Blackhawk 24 and a 38mm minimum diameter project I've been working on. I'll be sure to share the results here, but this looks and sounds very promising.

Incidentally, this system was designed with minimum diameter in mind, so this may be the perfect compliment to the Blackhawk series or similar projects.

Does anyone have weight or power restriction info about this unit?

What is the amount of force required to break free the magnets? If it takes 2 Newtons to be free from the magnets that's 2 Newtons less thrust that goes toward propelling the rocket upward. How does this loss compare to the extra drag & rail friction losses for rail buttons. It seems to me that a tower launcher, with virtually no friction losses, would still be the most efficient option.

Probably true - but in most rockets the drag added by the rail buttons or guides is estimated at nearly 10-15% of the total drag force. Even with a small penalty the advantages in terms of setup ease and speed of loading the rocket on the pad would be substantial compared to most towers.

I just installed two magnets into a Blackhawk 24 airframe--no problem at all. Easier than installing rail buttons, and not much time at all:

Draw line, mark drill spot, drill hole, swab hole edges with thick CA, insert magnet with rail slide (wooden piece with magnet in the middle and two rail buttons--holds rocket to rail & breaks away at the rail's top), push it in flush with the tube, push slide away leaving magnet in hole flush with airframe OD--viola, done.


All of three minutes per airframe magnet, two magnets. I can now hold the rocket up with just one slide easily, and it will use two slides. While holding it securely, it breaks away in the path of travel easily. No tower, no lugs, no buttons, no drag. This is looking very promising!

Would you be willing to post pictures?

What is the chance that the magnetic rail button will break free before the slide moves up the rail? Then you have a situation where there is little or no guidance. Imagine using a very high thrust motor and light rocket.
