Use an F motor for slow, graceful flights or pack it with a G motor for real excitement. We’ve even flown the Tiny Pterodactyl on an H-238 and amazed the crowd with a neck snapping transonic flight!*
* Nose weight was added to keep the CG forward of the CP during this flight. Some rocketeers like to keep two nosecones on hand: one weighted for higher power motors and a standard one for lower power flights.
