Default Blade 180CFX & 150S Main Gear 3D Model for Printing

Hi all.

After losing a few teeth on my new 150S main gear within minutes of getting it in the air, I realized it is is backordered pretty much everywhere. In the interim until things are back in stock, I whipped up a 3D model for a new main gear. I've flown around 12 - 15 flights on this so far and it is working great.

Recommend printing in nylon filament and using a raft to avoid the first layer squish to keep the teeth as perfect as possible. Oh, and print slow - you want as much fine detail as you can get.

If the mods think I need to move this please let me know. It seems we don't have a dedicated 150S forum yet, but I figure this thing is 80% a 180CFX anyway, so posting it here.

I have not flown my 180cfx in a while, but I kinda look forward to having to print a main gear. LOL. Big thanks to you for your contribution.

I have a printer, which can and does print nylon, if anyone needs one printed. Takes a day or two before I can print Nylon though because I have to dry it for at least 24 hours first before I can print it if I want any kind of decent print quality. Perks of nylon

I've had good luck keeping my nylon in an airtight dry-box with a couple of the large rechargeable Eva-Dry desiccants stored with them. But I have a few rolls that are beyond this and need to be baked for a bit to dry well. It's just tough to keep it dry.

Nylon is awesome stuff, though. I'm consistently amazed at how well nylon helicopter parts work. My smaller helis are all running printed nylon landing gear, and I've not broken a set yet even with how rough I am flying (crashing) the micros. They're both wearing nylon tail fins as well with the same result.

On the main gear - do keep in mind it is noisier than a smooth CNC-cut or injection molded gear. This is just unavoidable with the layer lines being inherent to FDM printers. Other than a bit of noise though, it's stood up to full collective pitch pumps and hasn't skipped a beat yet. It actually runs very smooth. I don't plan on running this forever, but I do plan to keep several on-hand for hard times.

I have a dry box but I don't use Nylon often so by the time I actually need it the filament still ends up wet. It's unavoidable, Nylon is extremely hygroscopic.

It's so hygroscopic I've run into cases where, before I had a dry box, I'd pull it out of the dehydrator and it would print great, but by the end of the print it would be noticeably wetter. I print straight out of the dry box which prevents that now... I don't print very large items with nylon because it's expensive and most of the time not needed. But I still have to dry it before use if it's been a few days since it was last dried.
