Acme Conformal® Launch Guides

Lower frontal drag than rail buttons!

Rail launch systems are great. In our view, they beat the old launch rods hands down. But frankly it can be a pain to attach those little guides onto your rocket. Just screwing them into the bodytube won't work. You usually have to contrive some backing plate or try to screw into a centering ring - - and that can be a very thin target to hit!

Not any more!

Now attaching guide rails is a snap with Acme's new conformal rail guide. They just glue onto the tube. That's it, just like the conformal lugs. What's more, these conformal guides have less frontal area than standard buttons, and that means less drag for your rocket.

• Acme rail guides are 6061-T6 aircraft aluminum; no flimsy urethane foam to wear out

• The base of Acme rail guides have a conformal radius that matches exactly to the airframe tube. Other brands do NOT.

• Acme rail guides are very low priced.

• Acme rail guides do not require screws. Screws require backing inside the rocket which can hang up cords and chutes.

• Compatible with Extreme rail, sold below.

Standard Extreme Launch Rail

100% compatible with Black Sky rail guides, but...

Features:

• Stronger: The Extreme Rail is 1" by 1" thick (compared to 1/2" by 1/2").

• Easier to use: The extreme Rail is a single piece 6 feet long - not a series of 2 foot sections.

• Sturdier: It has a 1/2" rod mount (compared to 3/8") and a heavy channel to mount to any pad that accepts a 1/2" rod.

• Safer: Because of its smooth single-piece design, there's no chance of snagging a rocket like there is on rails that are sectioned together.
  More Convenient: The Extreme Rail has one channel on each of its four sides! So, if one channel is plugged with residue, you don't have to stop and clean out the rail in the middle of launch day. Just use another channel (or another, or another...) until its convenient to clean the whole rail.

• Compatible: It is compatible with Black Sky rail guides,. So, if you've installed the Black Sky guides on your rocket, you're good to go!

• Cool: We know, looks dont matter to you. But just in case...this is one bad-ass lookin' rail!!

HINT: Teflon® spray prior to use makes post-launch cleanup a breeze.

Heavy Extreme Launch Rail

Standard size rail slots, but for heavier rockets!

Tested to 70 LBS. This accepts the same rail guides as the standard extreme above (and the blacksky rail), but is 10 feet long, and comes with a strong reinforcing spine for extra strength. Fits on any pad that takes a 1/2" rod. I used this rail on my 55 lbs hybrid level-3 project.

NOTE: This is not the larger rail previously known as the "Senior Extreme" which required large rail guides of a nonstandard size.

We no longer carry the senior. The Heavey Extreme uses the same rail guides as on the standard extreme but it is meant for heavy rockets. The Big Extreme rails were all over the range at LDRS 2002 in Amarillo. They performed flawlessly.

NOTE: For shipping and transportation purposes, the 10 long Heavy Extreme Rail is made up of a 6’ and 4’ section of rail, reinforced with an 8’ long heavy spine
