DESCRIPTION
The Expediter Rocket Building Kit is one of the ISP PERFORMANCE SERIES of kits, which feature factory pre-slotted airframe and through-the-wall fin construction and high power motor capabilities, the EXPEDITER offers sleek styling due to the use of LOC’s exclusive airframe reducer. The 54mm motor mount is great for low thrusting 54mm motors like the J90 or I65. This model missile is a great Level 1 kit that flies on a variety of H and I motors. It is a very cool looking, versatile rocket.
I built this rocket and it’s a very high quality kit. Recently just used it to do my level 2 certification flight with it and it flew beautifully with a J350W motor and perfect recovery using a chute release set to 500’. Definitely a nice solid rocket. Now I’m modifying it as a dual deploy
I actually have two of these, an older one with the 36" chute and the glue on fin tabs, and a "new" one as described above. Both are great fliers, allowing for something as small as a high impulse G up to a J. I would not recommend 54mm motors without nose weight as your stability cal will be below 0.5. This kit is light enough though a J90 with some nose weight is an AWESOME flight. I've added dual deploy to one of mine (the new one) and the 4 inch to 3 inch transition piece is a perfect place to mount it. Love this kit for it's flexibility in flights.
