- This totally could be your first DD flight, but it totally shouldn't be. The stakes involved are much higher than flying an L1 rocket. It is a good idea to have at least 3 - 5 successful dual deploy flights on at least two DD rockets before you start on your L3 so you know "what works". This is not a hard requirement, but may save you from lots of misery.
- The cost of a typical L3 project, from start to finish, is typically usually between $750 and $2000, depending on how much equipment the flyer already owns or borrows. The motor alone will typically probably be at least $250 at 2018 prices. Be sure you are this committed before you start to acquire parts! Rocketeers who rush through their certifications will likely spend the higher end of this range all at once, as they will have to acquire gear like altimeters, trackers, and parachutes that other fliers may already own from their past projects.
- Motor hardware is expensive! At 2018 retail prices, a 75mm 4G case (the minimum size with M motors from most brands) goes for anywhere from $350 - $500. Look to borrow this hardware from your motor vendor or another team member if you do not intend to fly enough to justify purchasing it yourself. Alternatively, hardware can be purchased used from other flyers for often close to half the price of a new hardware set.
