"Reliant" frame - modern lightweight Y6 frame for long range and fun (v2!)

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4845387.

Version 2!

Changes:

• for less manual filing I added an offset to the fittings (0,1mm on each axis, so 0,2mm in total) - this way hopefully there will be no / only very few) filing necessary
• I also added instructions for your CNC service / workshop on how to do the cut-outs (see 2 images)
• height of the arms has been increased from 18mm to 20mm based on several requests
• FC&ESC stack mounting holes moved 5mm more towards the back. This way the USB connector is better reachable (still not perfect, but given the design thats the best it can get)

Hint: The 6mm standoffs between the motor mounts are not necessary. You can also used a M2x10mm screw and bolt to directly mount the 2 plates together. I find it much easier to align them well with the spacer bolts (and kinda nicer), so i'm using these on my build.

Hi there!

I always loved the way a Y6 looks like. In theory up to 2 motors / propellers can break (just not on the same arm), and you can still stay in the air. Sadly it requires you to use a landing gear. However using this design with 90° flipped arms, this is not the case.

Regarding the used components the frame is basically a Y6-version of the #microlongrange, so from my findings the 1404 motors fit best. I'm flying the Y6 with 3s Li-Ion packs using 4" props. The sound is quite nice and definitely not annoying on 3s, which is very important to me.

With the 3s Li-Ion i get flight times of around 16-20mins (depending on if i got the GoPro on or not).

I do design frames for personal projects for fun and document the process in my Youtube-Channel.

Flight performance: coming soon

Notes about the build: The motor plates are pushed onto the arms, and the arms onto the main plates. They are then secured with spacer bolts. The spacer bolts are a tiny little bith shorter than the frame parts, which ensures you get a very tight and reliable connection. I didn't leave any extra space in between the parts. So depending on the drill diameter that your CNC workshop uses, you will need to do a bit of filing to make sure the part fit nicely.

I suggest using aluminium spacer bolts, as they save quite a bit of weight.

For mounting the motor plates on the arms, you need:

12 x M2 - 6mm spacer bolts: https://www.aliexpress.com/item/32831145268.html 24 x M2 - 3mm screws

For mounting the arms to the main plates, you need:

6 x M2 - 18mm spacer bolts: https://www.aliexpress.com/item/32831145268.html 12 x M2 - 4mm screws (or up until 6mm screws if you have them already)

For mounting the TPU camera mount you need:

2 x M2 - 18mm spacer bolts: https://www.aliexpress.com/item/32831145268.html 4 x M2 - 4mm screws (or up until 6mm screws if you have them already)

For mounting the TPU GPS mount you need:

1 x M2 - 8mm (or 10mm) 1 x M2 - nut

Would love to see others build this as well! Please send me a note if you did (or video link), or use the "Made" function :-)
