Unfortunately the only tracking # I have is the customs forms # that I sent in PM (LC578441684US). It generally works as a tracking number when I have international items delivered to me but looks like it doesn't work for your country, this is what the USPS tracking site spits out:
USPS Tracking™ is unavailable for this product for ZAMBIA.
I think it would have had tracking if I went with registered mail instead but that would have been double the price which was already 4x worth the cost of the wood in the tricopter frame
