From the old Rocket Silo, Rebel Rocketry brings you exclusively for the European market the Tripoli certification pins. Developed for the Tripoli HPR flyer to show your level or just pin it on a picture of your certification flight and hang in on the wall. These pins will only be sold to certified members of Tripoli and we need your TRA membership number to check your level. You can only order the pin up to your certified Level as a TRA HPR flyer.
