     About Us



The webstore is closed until further notice. There is an excessive amount of backlogged work due to the increase in sales and the loss of an employee in May. We need to catch up on this work and restock our reload selection as much as possible before reopening again. Due to several factors, I am unable to say how long this closure will continue for, but hopefully not more than a few months. We look forward to your continued purchases and support as soon as we are back up and running again on all 8 cylinders. We are sorry for any inconvenience this may cause.



Most Sincerely,

Scott Kormeier

Rocket Motors are safe & predictable only when properly used by responsible persons.

Responsible persons placing orders for High Power Reload Kits require a photo or copy of your NAR or TRA Membership card, School, University or Government agency credentials and a Photo ID.  At this time these items will need to be emailed to scott(at)lokiresearch(DOT)com.   

I will work with the webmaster to incorporate a file attachment at the time of checkout in the future.  

All Loki Research Dealers will be asked to obtain this information from responsible persons as well.

Thank you for your cooperation. 

All Loki Research hardware can be used for Experimental (EX) use for making your own propellant and reloads.
All Loki Research reloads are certified for use at both TRA and NAR launches. When you see hardware listed that does not say EX, that means there is a commercial reload available for it.

When you see a Loki Research case or complete motor that is designated as "EX", this means that the hardware does not have any commercial reloads made for it and is intended for experimental use only. 



When the term EX is used for 38mm hardware, the nozzle throat size is different/larger than what is certified for use with that case sizes respective certified reload.  These larger throats are what is typically used by people who like to experiment.

 UPDATED ON 5/20/15

Know what you are buying is the best, and not just a best buy.

All Motor cases are CNC machined by highly skilled American machinists

to ever increasing standards of quality.

54mm & 76mm Seamless DOM Tubing direct from Alcoa


- Made to standard OD hobby dimensions with the best possible ID & Wall tolerance offered byAlcoa.

     - 54mm -1.939”ID +/-0.006” IR, 0.094” Wall +/-0.005” IR, (2.127” OD)                              

     - 76mm -2.753” ID +/-0.007” IR, 0.116” Wall +/-0.006” IR, (2.985” OD)                              

      (IR = Individual Reading x 3or more readings/locations = much higher dimensional quality than an average of multiple readings)


We are in the process of trasitioning back to Type 3 Hoadcoat on all motor cases and most forward bulkheads.

Currently all 54mm and 76mm cases, and larger 38mm cases being shipped are Hardcoat plated.


Polished ISO Graphite

All Graphite nozzles are made from high quality ISO Molded material.


Taylored for reusability in small solid rocket motors.

When polished, they can be extremely easy to clean post flight.
