Hobby King C3 Tricopter Tail Covers

thingiverse

At last I have completed designing the tail cover for my C3. Leaving the connecting end as a blank, un-profiled makes it easy to trim it down according to the size of the motor being used. I've posted two versions of this design online, which will allow anyone who isn't keen on wings to make their own. You can see from the attached photo that once printed out, it's not too difficult to split the model in half and then profile the connection area. This can be easily welded back together using some acetone, allowing you to put the two parts back into place smoothly. I will add a second photo of my unit once I have finished working on the cosmetic touches that it still needs. Feel free to post your thoughts and offer any advice - it's all welcome. UPDATE: January 24th 2015 To go along with this design, I have also uploaded another STL file which is called "First Solid Stage 2.1". This second version was needed because the wings on the first version kept getting in the way of the tail propeller after they had been completed. It seems that at least one person hadn't thought about the space needed between these parts! To resolve this issue, I've lowered the wing positions slightly, and made a few tweaks to get things right. Before printing out the new design for myself, I want to check over it a little bit more and make sure that it will all fit together perfectly. Here are some additional details about my setup so you know what works best for me. Instructions: I printed the winged version of this unit in ABS plastic with side walls that were 2mm thick. When making my initial prints, I was careful to adjust the base density to just under 20%. This really made splitting apart my unit and then welding it back together using acetone relatively easy. Additionally, by applying some additional layers within the model using acetone after completion, this has added a nice layer of extra strength which is definitely worth doing if you plan on making one like I did. The self-tapping screws can now fit perfectly in line with two specific bulges along the length of my unit, as these had been adjusted for both the differing thicknesses within my model and to make room for my frame's unique features. I made sure to print these additional pieces that were designed specifically to keep the parts attached together at 100% density so that they provide a secure anchor for your screws when they're used.
