Reloadable motor RMS 29/180 - Aerotech

A 29mm reloadable high power motor is usually the first High Power motor used. Level 1 certification requires at least an H motor so this motor is usually the first choice. This motor can be used in kits made for small 29 mm motors, like some Public Missiles and Madcow Rocketry, or Aerotech kits and Estes Pro Series kits.

They are assembled in a similar way of the smaller reloadable motors, like the RMS 29/40-120 or the RMS 24/40 therefore it is nothing different from what you are used to.

To use this motor you have to choose a suitable reload, assemble it following the instructions, dispose of the residues after each flight and clean the motor accurately. The motor can be used an indefinite number of times.

RMS motors are made of aircraft-grade aluminum and consists of three parts: the case, the forward closure and the aft closure. The forward closure holds the delay and the parachute ejection charge, the rear closure holds the nozzle and, being of a larger diameter than the motor body, it acts as an engine block as it butts up against the motor mount tube.

When to use this engine?

This engine is the most widely used motor for the Level 1 certification flight because it uses an H128W reload which is a good compromise between power and cost. It has also a G reload therefore you can use it even if you don't have a certification, maybe in the same rocket you will use to get it.

The following reloads can be used with this motor:G75J
H128W
H165R
H238T
