Shipping regulations require all motors to be shipped via ground transportation. Smaller motors may be shipped using the US Postal Service. eRockets is an authorized shipper of motors via USPS.
Single-Use = SU there are a small number of delay length choices (4/7/10/13 seconds), and they cannot be altered.
EconoJets are SU's, except limited to F impulse. With limited delay choices.
Economax motors are also SU but are all 80Ns or above impulse.
Metalstorm-propellant High Power SU motors require a L1-certification to purchase. With limited delay choices.
"Model Rocket" reloads are specifically for the 29/40-120 Hobby Line casing. With 1 or 2-grain configurations (1-grain motors include cardboard spacers). You can choose the delay, but since this is a motor you have to assemble, the delay grain is separate and so you can modify the delay. This is one of the most popular systems amongst mid-power flyers.
Loadable Motor System(LMS) to get around shipping restrictions. It is a single-use motor that has to assemble.
High-power RMS reloads specify which casing they are used in. Or use the adaptable casing, it lets you use fewer motor grains in a case than the case was designed for.
New high-power Disposable Motor System, use the Delay Adjustment Tool to optimize the delay.
Six Propellant Types
White Lightning™ (W) - A brilliant white flame, dense bright white exhaust and a throaty roar are the hallmarks of this popular propellant. Easy to track. Exciting to watch! White Lightning looks and sounds like actual sounding rockets and launch vehicles. Special effects professionals and aerospace companies specify the AeroTech White Lightning propellant to achieve realistic simulation.
Blue Thunder™ (T) - Produces a bright violet-blue flame with a minimum of exhaust smoke. These motors provide a higher level of thrust than White Lightning or Black Jack motors of the same total impulse. Blue Thunder is the perfect propellant for high lift-off acceleration.
Black Jack™ (J) and Black Max™ (FJ) - Provides the high visibility tracking of dense black exhaust. In addition to a distinctive lift off roar, Black Jack motors give your models lower acceleration and longer powered flight than White Lightning or Blue Thunder motors of the same total impulse. Black Max provides slightly higher acceleration than White Lightning Propellant.
Redline™ (R) - Distinctly different from its propellant relatives, Redline provides unique visual and thrust characteristics for larger airframes and performance oriented flyers. The proprietary AeroTech formulation imparts Redline with its signature vivid scarlet flame. Redline’s burning rate lies midway between that of White Lightning and Blue Thunder. Photos don't do justice to the "laser-beam" intensity and color of Redline… you have to see it to appreciate it!
Warp-9™ (N) - If you blink you’ll miss it! Displaying a prominent yellow-orange flame studded with “mach diamonds”, Warp-9 is AeroTech’s fastest-burning propellant. Originally developed for Orbital’s Pegasus® fin motors, Warp-9 is perfect when you need the highest thrust possible from a given motor size. Alternatively, when used in an “endburning” grain configuration, Warp-9 delivers unique thrust curve profile.
