We’ve run out of arms for both the MiniTricopter and the Tricopter V3.5. The sharp corner arms turned out to be too difficult for the manufacturer to make reliably and the yield was low. (Though they didn’t inform us of this until we put in the latest order). So now we’re going back to the rounded corner arms again. But from the new manufacturer, so the quality will be improved compared to the very first arms we sold. The new arms are being made and will ship out to us soon.
In the mean time we can offer the tricopter kits with “second quality arms” at less than manufacturing cost. A $7 discount is available for the Tricopter V3.5 kit and $5 discount for the MiniTricopter. Use the discount code uglytriarms for the Tricopter V3.5 kit and uglyminiarms for the MiniTricopter while in your cart. For spare arms (both full length and 1/2 length) that are not part of a kit you can use the coupon code uglyarm ($1 discount per arm). Make sure that the coupon code works before proceeding to the checkout page.
By “second quality” we mean that the arms have not passed our usual quality control and may be scratched, somewhat uneven on the surface, of a little bit uneven length/width, or with other minor faults. They are still straight and fully functional (maybe a bit of sanding down of a bump might be needed, but not more that that). These arms are available and in stock even if the “normal quality” arms are on backorder, which means that your tricopter would be shipped without delay. The arms may be of the rounded or sharp edge design, but they will not be mixed. You cannot choose which type you will get.
