HYPERION PLYWOOD SPACERS FOR BACKMOUNTING 40MM OUTRUNNER MOTORS
[HP-ZS40PSP]

These are hard plywood spacers for backmounting of outrunner motors.Three sizes are available to fit almost any motor on the market.See Details

These are convenient as the length can be easily adjusted (see datasheet for a table of lengths), and the can be easily sanded to provide some small addtional thrustline correction.
Finally, the wood composition helps reduce vibration, and provides some extra protection in a crash as they give way under high loads.
Once the length has been determined, stack togther and apply thin CA glue to make a solid, one-piece spacer.
