Hi All, I have a few bnf quads I’ve learned to fly, solder, and rebuild however this will be my first build from scratch. I want to do this build right and wondered if you could offer any advice. I’m unsure how I should wire my esc to my FC as I want to ensure I’m not limited to the output of a few pads as detailed in the matek wiring instructions. Oscar Liang has mentioned a possible alternative and wondered if he or any others have found a good solution. Parts list below: Armattan rooster Matek f405 ctr FC Dalrc 40a 4-n-1 blheli 32bit ESC 12 gauge power leads 2306 2450kv hypetrain motors Foxeer predator mini Tbs unify pro hv Tbs triumph to unify Fatshark hd3 Laforge diversity v4 Ibc mad mushroom antenna Xair 5.8 directional antenna Frsky r-xsr receiver Thunder power adrenaline 4s 1300 100c Taranis x9d plus M9 hall gimbals GoPro session 5 GoPro 2.5 mm fpv Lens to predator HAKKO FX-888D Ive looked around YouTube and forums but haven’t seen much info out there. However that’s understandable as the parts are fairly new to market. I really apprecIte any help you can offer as I stare in agony at all the parts just screaming to fly! Thank you for your time and help, Mark • Posts: 12,099 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 04-Apr-2018, 09:28 PM (This post was last modified: 04-Apr-2018, 09:30 PM by voodoo614.) Matek website has great diagram on how to wire up everything. Your FC has a great large pad so you can wire the power to your 4-in-1. I would wired it that way. Simple! If you want more complex wiring, you can check out Joshua Bardwell manuel for his FC. There is a section for wiring to 4-in-1, and it will also applies to yours. http://www.mateksys.com/?portfolio=f405-ctr#tab-id-3 The Dalrc ESC has a port that comes out with all the signal wires. You just have to figure out which wire from the Dalrc that is signal 1, 2, 3 and 4 and solder to the corresponding signal pad on the Matek. If you draw a diagram, one of us and verify whether it is correct or not.

It is just a big resistor.

Make sure you post some pics of your build, you're using all nice components Posts: 12,099 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 I found 12 gauge too thick. Difficult to plug into lipo due to not being as flexible. 14 gauge is good enough. Don't forget the 60/40 or 63/37 solder.

Here are few to start: Frankenbuild: New build: To Oscars recommendation on his site, I went with 63/37 kester solder, and was actually having issues with the 12 gauge as it was too stiff as you said voodoo. Thank you for the advice!! Thanks again everyone! • Posts: 177 Threads: 4 Likes Received: 52 in 47 posts Likes Given: 88 Joined: Apr 2018 Reputation: 5 08-Apr-2018, 01:06 AM (This post was last modified: 08-Apr-2018, 01:10 AM by MarkII.) Hi all, I’m not sure what to do with VCC and Current wires from esc. I assume current goes to the current pad on the FC, but am unsure if VCC is necessary? What should I do?

Clean soldering. Heat shrink is a bit much, but who am I to judge. I assume you have the FC mounted that way just for photos. If you plan to keep it that way, don't forget to change your orientation in Betaflight Configurator. • Posts: 177 Threads: 4 Likes Received: 52 in 47 posts Likes Given: 88 Joined: Apr 2018 Reputation: 5 08-Apr-2018, 06:34 AM (This post was last modified: 08-Apr-2018, 06:35 AM by MarkII.) Thank you voodoo! Yea just to solder, here’s where I am now. Just need to solder both power leads and the r-xsr and I’m ready to go. |
