Back to the rounded edge carbon fiber arms. Second quality arms available in the meantime.

Written by

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.

    Hi David,
    as much as understand your somewhat forced decision to go back to the rounds, I, and probably many others, would greatly appreciate it if you would somehow find a way to offer the square booms again. They were such an improvement over the rounder ones and a truly necessary upgrade for my Tricopter V3. I´m not asking you to find a solution right away, just as soon as it is realistically possible for you (whenever this might be 🙂 ).

      Been searching for a good manufacturer for ages. Will continue to do so. 10x10mm booms are smaller than most manufacturers can do. Opening a new mould at each place is really really expensive and they never live up to the standards I want for the finish. By far the most frustrating part of all of the parts. Hope to find a new manufacturer though. We’ll see.

    Hello David,
    I have placed my order a couple of hours before this post. What would be an expected delay before arms and mini-tricopter kits are available again?

    1. RCExplorer - David Avatar

      Shouldn’t be more than 14 days according to the manufacturer. It should have said on the product page and in the cart that the kit was backordered? Sorry about the delay

    Hi David.
    I placed an order on the 28th of feb. I got an email saying that it has been dispatched. does that mean I will be receiving a set of the square arms?

    David. Is on your plans to build a 250 size? 🙂

    1. Terje Avatar

      Regarding 250 size: Cut front booms to 135mm, rear boom to 150mm, use 2300-2600Kv motors with 5? props. Go fly 🙂 (Or make a ridiculously complicated custom build to keep weight down, that is what I tend to do…)

        Everything should be reduced in size not only the arms, are you working on a 250 ? Take my money!

    You said on the 2nd of march that the arms should be back in stock in 14 days. Aaaaaand they’re not. Maybe i’m impatient.

    1. RCExplorer - David Avatar

      I’m impatient too 🙂
      My supplier had promised that they would be sent in a couple of days when I made that post, but then they had some sort of problem and the arms were delayed… I can’t really do anything about it, and it is really frustrating. But, you can order the “uglyarms” if you get too impatient. I’ve just added a coupon for “spare arms” as well, if you’re not planning on buying a kit. Sorry, but that’s all I can do 🙁
      As soon as the arms arrive, the stock will be updated.

    The arms have finally shipped out. Waiting eagerly for them to arrive. Should be early next week
