TMT is pleased to announce the certification of a new line of 54mm motors from Skyripper Systems. Todd Moore's line currently consists of three sizes: Short, Medium and Long.
The fuel type is ABS plastic and there are two speeds for each size case. The speed is set by drilled injector plugs, one natural brass (Gold) and the other black.
The motors are filled as a typical U/C hybrid with a 3/8" 'thru nozzle' fill tube, and a forward closure vent.
The six motors certified are as follows:
Designation, Size, Total, Max, burn time, Nitrous CC, Total Weight (Pre Nitrous)
K347B, Long Black, 1529NS, 1901NS, 3.57s, 1130, 1542g
J337B, Med Black, 1073NS, 1876NS, 3.0s, 830, 1338g
J348B, Short Black, 716NS, 1553NS, 2.2s, 550, 1224g
K257G, Long Gold, 1733NS, 2461NS, 6.08s, 1130, 1542g
J261G, Med Gold, 1248NS, 2354NS, 4.9s, 830, 1338g
J263G, Short Gold, 844NS, 1852NS, 3.5s, 550, 1224g
These are excellent motors. As with all of Skyripper's motors, the Preheater is a less than 30 Gram AP grain, which makes the reloads entirely legal to ship through the Standard Postal Service channels and both ready to use out of the box, and easily obtainable by all HPR flyers.
