Attention for time critical orders! Through a special permit, USPS will allow us to ship Composite motors by Parcel Post only. This process is not like priority, and can take 5-10 business days. It does not track, or move on weekends, like priority mail. It will show you an incorrect delivery date and only update when it leaves our local office and arrives at yours. It will not update along the way. Fedex is available, however they will charge an additional $40 hazmat fee to go by ground, and need an adult signature. Check the box in the shopping area below the quantity when ordering.
We are testing the market, so if you are interested in different lengths, please email us.
