Contrail has recertified the 75 MM Hybrid line to utilize their, now standard, Pyrodex ignition system. The first few motors in the 75 MM line utilized a manufactured igniter. All were retested and found to have much smoother ignition characteristics with the Pyrodex preheaters. For all customers that have the original non-Pyrodex igniter, contact Contrail for specific instructions for their motor and the new igniter systems.
