The RMS 18/20 reloadable motor from AeroTech has the same size of an Estes C motor (18 x 70 mm) but can be loaded with D class reload with a thrust up to 4 times higher. You can use this motor in rocket kits made for C class engines, or even in the larger rockets made for B engines (not too light, you don't want to lose the rocket and the motor at first flight, don't you?). Keep in mind you will have a thrust of 2 to 4 times that of an Estes C...!
You can use this motor also in rockets made for D motors, but you need an adapter like the Estes Standard to 24 mm adapter, sold separately.

To use this motor you have to choose a reload, assemble it following its 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. The two notches in the rear closure fit the engine hooks used in every Estes-like kits.

Aerotech RMS reloadable motors are easy to use but we suggest you to follow the instructions closely. After each flight the motor must be cleaned very well with a wet cloth or a “baby wipe”.

When to use this engine?

Every time you want your Estes-type rocket to go higher.

The following reloads can be used with this motor:
