The EMK4-24-80 Engine Mount Kit allows you to design or convert most any BT80 based model rocket for four 24mm cluster flights! All FlisKits engine mount kits come with highly detailed instructions to allow for easy construction, super strong mounts and long life.
The EMK4-24-80 engine mount employs four BT-50-04 (4 inch engine tubes) with engine blocks for each tube, centered in a square pattern with rings designed to fit standard BT-80 body tubes with a 0.021" wall thickness. Thicker walled body tubes can be used by lightly sanding the centering rings to fit, after assembly is complete. This mount does NOT include engine hooks but engine hooks can be added to the mount if desired.
