     About Us


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

All Loki Research standard motor cases are CNC machined by highly skilled American machinists

to the highest standards of quality. We start with the highest quality 6061-T6 DOM tubing available today.

Seamless Drawn Over Mandrel (DOM) Tubing direct from ARCONIC


Designed to fit standard hobby airframe and motor mount dimensions with the best dimensional tolerances offered by ARCONIC.

- 38mm - 1.334" ID +/-0.005" IR x .083" Wall +/-0.004" IR x 1.500" OD (REF)                         

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

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


IR, or Individual Reading means tolerance measurements are taken at 3-5 locations and all readings must be within the stated +/- tolerance. IR tolerances provide much higher dimensional quality and concentricity than standard average readings of our competitors extruded and DOM tubing. Since our tubing is called out by the ID and Wall dimensions, we have a known, guaranteed tolerance for the ID where our phenolic liners and other internal components must properly fit, all without additional machining.


Standard tolerances for COTS tubing (both DOM and extruded) use the average of all the measurement readings taken (3 to 5) which means some locations may be on the outside of the tolerance on the low side and other readings may be outside of tolerance on the high side while their averages stay within the tolerance. Extruded tubing is even larger toleranced and is the very reason why we discontinued the old school 98mm Loki hardware line.  So what does this mean?


This can mean a tube with an out of round ID and an ID that is not concentric to the OD. This can produce an extremely unbalanced tube and can cause severe coning issues in minimum diameter and/or high speed flights. Standard COTS tubing is also called out by OD and Wall which means the ID has no guaranteed tolerance and out of roundness can be even worse. This can be the difference between a motors internal components fitting and working properly every single time, or not. Onlinemetals has a great resource for standard tubing tolerances and many others here. CLICK


All Loki Research hardware is Hardcoat Anodized in Type 3, Class 2 Blue on all motor cases and bulkheads for superior protection as compared to the Type 2 coatings of most competitors.

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 or Experimental", this means that the hardware does not have any commercial reloads made for it and is intended for experimental use only.
