All Contrail Rockets 98mm Hybrid Motors have unique features which allows for a highly versatile, simple to use motor system.  Features which make Contrail Rockets Hybrid Motors so versatile are:

--  All Hardware is Anodized and Dyed for a Super Hard Finish that will not tarnish, rust or oxidize from use or handling.

--  Motor Cases Feature Bolt Together Design that allows for easy assembly and disassembly, with out the worries that threads will get dirty or damaged. 

--  Ultra Tuff Reusable Graphite Nozzles Allow for multiple uses with the same nozzle.  On 98mm Designs the Nozzle Carrier is the same for all reloads and a swappable graphite insert is used to reduce the overall cost of nozzles. 

--  Coaxial Vent Assembly allows for the vent to be routed through the combustion chamber.  This eliminates the need for a top vent on motors. 

--  Press Lock Injectors are Included with Reloads rather than a Compression Fittings, for quick assembly.  You Receive New Press Locks with each reload!

--  No AP Preheaters or GOX Type Ignition.  Simple Ignition Method using Pyrodex Pellets.  User Supplied Pyrodex Pellets (Available at your local Gun Store) offer extremely reliable, non-regulated ignition method in order to avoid BATF and DOT Regulations imposed on AP Propellants

--  High Regression Polymer Grains are available in all Case Sizes!  Increased Regression Rates increase the possible motor combinations available in all hardware sizes! 

--  Cast Grains allow for multiple burn profiles and special effects including Smokey grains, Sparky Fuels, and other Effect Fuels which deviate from the traditional motors. 

--  All 98mm Motors fit Standard Aero Pac Motor Retainers

--  Multiple port Injector Baffles allow for low and high thrust profiles as well as every combination in between.  The 8 port injector can have some of the ports plugged during burn to reduce cost of the reloads as well as alter the burn characteristics.
