This pack contains 4 Rocketarium Stainless Steel Motor clip sets form 18mm Engines. Rocketarium clip is a longer version of standard clip, which rests on the motor block and is more durable than standard clip.*
The set comes with 4 clips and 4 thrust rings and is designed for Standard 18mm engines, such as Estes "B" engine or Aerotech 18mm RMS
Width 0.12", Thickness 0.025", Length 3" *
Requires 3.25" or longer 18mm motor tube.
* In the standard motor mount - motor clip often damages the tube when ejection charge is fired. The ejection charge pushes the motor down and thin paper wall is the only thing preventing the clip from being pushed out. You will often notice that the clip in the standard mount falling out or can be freely moved up and down after couple launches. Rocketarium clip is longer and it rests on the thick thrust ring, which does not allow the clip to move down and damage the tube. Since the clip is longer - you need 3.25", or longer motor tubes, which are available separately.
