Hi Ian,
we ran out of these faster than expected, I think there was pent up demand for this item because we sold our entire stock in a few days. We will likely place an expedited spare parts order in the next few weeks so that our customer do not have to wait for ocean freight shipping. As an alternative, you may want to try the motor for the B25, it is very close in size and Kv to the P-38. http://www.motionrc.com/fms-1450mm-b-25-4023-kv1000-motor/
