Reception
Estes model rockets are popular and used by a large number of hobbyists and educators. However, measurements reported by a group at the University of Central Arkansas found that Estes rocket motor models A3-4T, A8-3, B4-4, B6-4, C6-5, and D12-3 have a measured impulses from 15.4% to 22.8% below the claimed impulse. A study at the Australian Defense Force Academy found Estes D11-P motor to have an impulse 11.4% below Estes specifications and the C6-0 motor to be 4.45% below Estes' specifications. A third study found the A10-PT motor to have a total impulse 20% below Estes' claims.
