Getting back

#1

Hi!
It’s been a long time since I posted here, but I wanted to get back on track and fly these little dudes again.

I was looking to try a 820 build, need to complete the list before pulling the trigger:

Thanks!

I’d recommend this frame: https://www.banggood.com/DIY-Micro-FPV-RC-Quadcopter-100MM-Brushed-Frame-Kit-Support-8520-Coreless-Motor-p-1128232.html?cur_warehouse=CN

If you keep the build low, you can fit some 65mm kingkong props on there.

Love that frame ! You could use some 2s brushed 8.5mm motors

Thanks!
Which batteries are you running on that build.

Do the H8 blueboard works with 820 motors? I don’t think it supports 2s right?

#5

I use some random 700mah 1S lipos I got cheap from Amazon. 16 EUR for 6 if I recall correctly.

I have no experience with the H8 board.

#6

No the Blue board regulator is rated for I think 6v, you’ll toast it at 2s. I have. 8mm motors will be fine to run on it

I was shopping around and found this deal:

https://it.gearbest.com/rc-quadcopter-parts/pp_638488.html?lkid=10040898

I ordered 2x since it is the same price for 1! They are spare parts for a quad that it is not direct drive but I’ll give it a go anyway.
I will let you know how they work!

I am looking for some cheap LiPo deals now. Ordered the frame from bangood also.

I will have an update when I receive everything!

So things started arriving!

I got the frame, motors and batteries but the motors actually have 1.2mm diameter while KingKong 65mm have I think 1mm. Can I drill the blades using a drill bit?

#9

1.2mm shaft is odd.
You can totally drill the props out though, aim for 1.1 to 1.15mm or so, you want a tight fit.
Then be sure to support the bottom of the motor so you don’t pop a motor cap off.

#10

Usual motor shaft diameters are 0.8mm and 1mm.

#11

Yeah they were listed at 0.8mm but they are actually 1.2mm! Not sure if I am able to find 1.15mm drill bit!
