Hey guys! I've been silently lurking for god knows how long now, finally got some extra fun money to start work on this amazing build! I'll be using Protopasta carbon fiber PLA for the printed parts. I'll also be documenting the build on Youtube (Links to come). In the meantime, I was wondering if any one has some sage advice for this project?

It begins!

Hi Killsec.
It's good to have you here. Have you checked on eBay? I found those small micro switches there. eBay sellers ship overseas to a PPO and all that stuff.

I recommend 3110 motors with 13  inch props or 4110 motors with 15 inch props like DJI1555

Greatly appreciate that and will look more into those and base my decisions on my findings, thanks for pointing me in the right direction!

Hey Killsec, I haven't tried that type of PLA yet. Is it expensive?. Does it requires a regular extruder?  What is the temperature?

Protopasta Carbon fiber PLA is a bit on the expensive side, I think it runs 40$ USD for .5kg. I did, however, buy a roll of Hatchbox Carbon fiber PLA to see if the results were similar because you can buy double the amount for the same price. Let me start this off by saying that both are easily my absolute favorite materials to work with because they produce an absolutely mind blowing finish. at .2 layer height I can barely tell its a printed part. They are both a lot stronger which means less infill. One of the things I'm going to do is dial in a good mixture of structural integrity to weight reduction because you clearly don't need as much infill as you would with standard PLA.

For my temps I print at 200c and 60c on the bed. For nozzles this shit is abrasive so definitely get some abrasion resistant nozzles, they are super cheap and easy to swap out any ways.

Pretty much between hatchbox and protopasta carbon fiber pla, the difference is quantity for the price. I love hatchbox and the only reason I tried protopasta was because I had no idea Hatchbox already had a spool of it

I'll have a more thorough review for both on the blog soon.

Hey, good question. you need to find the COG or center of gravity when the drone is complete. First, tight the locks up according of what you see in the pictures, then when the drone is finished, put on the battery and everything that make it be heavier, affix with a knot a large piece of thin cable in the middle of the drone about the wall that divides the space of the battery and the lifting mechanism, hang the drone from your ceiling, a tree or a ladder and make sure that it stays in a perfect horizontal position. If not, move the locks and the "T" arm-leg supports until the drone is perfectly horizontal. You can do it after or before drilling and wiring, but drill the carbon tube horizontally so the wires have room to move back or to the front when you adjust the center of gravity.
I strongly recommend you to print and use the position Locks that have the bolts and screws externally so you don't have to drill on the carbon tube directly.

Please feel free to ask questions.

So I finally picked up work on this again, got my motors, props, and escs, the only thing I'm missing is a PDB. Does anyone have a recommendation for a good one?

Hello friend,
In order to get those files, please try to get a hold of Steven Wagg who is main designer of this drone, he is the moderator Cdrskull.

It is better to test all that system before to assemble it. I did it according to the diagram and the contacts worked inverted, so i had to change the wiring. Try pressing each end stop with your finger until the servo motor stops when pushing down and also when pushing up. I posted two pictures of the system disassembled when I tested it.
