I did design them myself. They may not be the best design because it's the first time I have ever designed anything. I will be happy to upload them on Thingiverse if you find them useful. Anything in particular that you may be interested in?

Definietly the arm guards and the two peices up front by the camera. It looks like they might give a smidge more camera protection?

I have uploaded the arm and front guards to
https://www.thingiverse.com/thing:3257701
Both need to be glued to the carbon and I will need to change the design of the arm guards so they are easier to glue together. They are also a bit big so you may need to snip off a few pieces to mount the motors. The arms on the MD frame get damaged first so the arm guards should help. Also, Micro Eagle is so big I needed a bit extra to protect the lens. Hopefully the guards stay on after crashes. Good luck! If you have any suggestions please share.

Thanks a ton. Now to buy some TPU.

I have only ever tried one, SainSmart but I think it prints great with stock Ender-3 extruder.

Perfect thanks, I'm using the ender 3 also.

I have also uploaded an XT30 holder and a canopy that also holds a rx. I hope you find them useful

I was actually just thinking of modeling up an xt30 holder, thank you!

Please check the Thingiverse for a front bumper I just uploaded. Second day flying the drone it caught a top of a pine tree and tumbled down. Smashed front brace and a side plate. The front bumper should give it a much needed protection. The picture shows the bumper on a 2.5" MD but it will fit both.

Nice. I'm waiting til after Christmas to buy my red spool of TPU then I'll be printing a bunch of these, that one especially.

What glue did you use to bond the TPU to the carbon? Superglue?

Superglue seems to work fine. It holds pretty good but you can still separate parts, it's not final.

I think you should be fine with these motors. They are not as efficient as 1404 but they are not too bad and more fun so even if the flights are shorter you should be happy. I usually fly with 650mAh 4S batteries around the house and get 4.5-5 min on average. The problem is the battery sag if you push it harder. If you do you may get low battery warning after 1-1.5 minutes. But it will still fly long enough. If you fly it like less aggressively like 1404 you will be fine. These are nice motors. I have older Dys 1306 and, oh, man, them bearings just SUCK!

ikr!! idk why but ive found so many motors from different sizes and many work so well except they wear out so quickly because of the bearings huhuhu. So the battery will sag but itll still last a while. so a 550mah will be alright for like 3-4 mins right?

if you had to decide DYS 1404 4300kv (or 6000kv) vs EMAX 1306 4000kv

It really comes down to how you like to fly. I love 1306 4000kv motors. I find 1404 motors boring. 1404 is about efficient cruising. Much easier to do tricks with 1306 though you will have to fix your drone more often. If you just cruise with 1306 you may easily get 5-6 minutes out of a 650mAh pack. A bit worse than 1404 in terms of efficiency. The problem is that once you have all that power at your disposal will you just slowly cruise?
You have to try it for yourself. If your 550mAh batteries have decent c-rating you should be fine with 1306 regarding the flight times. Give it a shot!

What can I say? All cool kids 3D print now! 😎
As for the Butterflight, I was tempted to flash Betaflight but since HelioRC is kind of designed for Butterflight I thought I would give it a go. On top of that, I think I have put too much conformal coating on the boot button. Oops! 🤭

Thank you very much!!! Obviously, we are not strangers anymore .... Hahaha! :grinning:
Thank you for bringing the screws to my attention. Hmm, gun metal, that is class!
Or wait till I get it out for a spin and it gets a mud bath :pig:

Thanks a lot! Though because it's so new and shiny I am very reluctant to take it out while the yard is wet and muddy. I just need to throw it in a puddle to get it over with...

Hahah yeah, I was the same with my first ever build, until I crashed it on it's maiden flight LOL

Thanks!
For maximum performance/distance, you probably want the antenna ends at 180 degrees. However, this is not a long-range quad. I have experimented with different antenna placement on a smaller MD and about 60 degrees gives me much more distance than I ever need. Within about 300 yards I never get a failsafe at 100 mW tx power, not even close. At the same time, 60 degrees is much easier to mount on 2.5-3" drones.
Also, I believe I might have seen different antenna mounting suggestions on either TBS or Frsky website including 180,90 and 60 degrees variations. 180 degrees may just give you the longest range if it's what you are after.

You're correct 180° is the best. If you're only going out a KM or so, you're probably good.

Not even that far. I have had a very good luck with R9 receivers (mini and slim+) so I now use the mini instead of XM+/R-XSR on all quads I build.
