Thanks Biggles for getting it out to me so quickly. Since I won this frame from intofpv I'm going to use it to make a tutorial on how I build my quads from start to finish. and answer any questions anyone may have along the way. I could make a video, but I have a face and voice that's better for writing tutorials. for this build I will be going with, ZMR-X210 frame of corse Tiger T-Motors MN2204 2300KV motors.

Be careful with carbon fibre on any carpet with synthetic fibres, as you will build up huge amounts of static electricity, and trust me it hurts. Also not too good on your electronics either. That was another IntoFPV safety Tip. lol I set it down on the carpet just to take a pic. if you were to see my table, you would probably think that it's safer on the carpet. but that is a very good point, thanks Biggles. next I start soft mounting my electronics and trimming down wires to prepare for soldering. I have a Luminier quick swap pdb with 5v bec that I use to bench test my motors and esc's for rotation.

I always use flux when soldering cause it helps the solder flow better, and helps with a better solder joint. I would prefer to use a liquid flux cause it's easier to clean afterwards, but I recently ran out so I'm using this paste flux that I got from Radio Shack. so to reverse the rotation on my motors what I do is switch the outside wires from the motor to the esc. so when it's laid flat the wires aren't crossed. I know you're probably saying why don't I just do it in BLHeli? I've been told that can cause desync issues on certain esc's. so I feel it's just better to let the hardware do it.

That is exactly what I was going to do on my build as it makes for a cleaner installation. "Damn the torpedoes!!!

I was told that it's common on the DYS XM series. but considering these are suppose to be a better ESC with a faster processor, I personally think it's better to switch two wires rather than using BLHeli. • Posts: 391 Threads: 23 Likes Received: 50 in 41 posts Likes Given: 56 Joined: Feb 2016 Reputation: 8 Looking good so far, did you prepare the carbon in any way? I usually don't bother.

I accidently put one of mine in wrong on my ZMR 250 and when I discovered it instead of taking it all out and resolding etc, I just switched it in BLheli and I've had no problems. It was a RotorGeeks 20A ESC. I'll do a little research on the ones I've got now before I do that. "Damn the torpedoes!!!

I usually don't bother. for the most part I don't, just where the power leads go through. • Posts: 626 Threads: 96 Likes Received: 531 in 218 posts Likes Given: 188 Joined: May 2016 Reputation: 20 after I'm done soldering the motors to the esc's I wrap them with heatshrink. then I'll mount the motor and heatshrink the esc to the arm. I always use loctite thread locker on the motor mounting screws to make sure they don't come lose and rattle out. don't wanna lose a motor mid flight. I also make sure the screws I'm using aren't to long that they bottom out and make contact with the coils in the motor. • Posts: 626 Threads: 96 Likes Received: 531 in 218 posts Likes Given: 188 Joined: May 2016 Reputation: 20 20-Jul-2016, 03:20 PM (This post was last modified: 20-Jul-2016, 03:40 PM by JimmyLe813.) now that I have the motors and esc's all mounted and soldered in place it's time for the flight controller, reciever, and fpv stuff. oh I forgot to mention that when soldering your components always, I repeat always check your positive and negative wires. don't be the guy (or girl) with the "why did my esc catch fire?" post. only to find out later that you had your wires crossed. now normally I would solder all my wires directly to the flight controller, but if you're justing starting out, or not comfortable with soldering I would advise using the pin headers. just for the simple fact that things will go wrong, you are going crash. so by using pin headers it makes it easier to trouble shoot and switch things out. • Posts: 626 Threads: 96 Likes Received: 531 in 218 posts Likes Given: 188 Joined: May 2016 Reputation: 20 21-Jul-2016, 12:54 AM (This post was last modified: 21-Jul-2016, 12:56 AM by JimmyLe813.) once I have the pin headers soldered on, I jump pins 5 and 6 on the IO_2 connector for telemetry. you could always just connect the two wires together but I prefer doing it this way cause it makes for a cleaner build. next I'll depin the receiver, I do this by using some cutters and cutting all the pins on the top row off first. then I'll just remove each pin one at a time. next I'll remove all the wires that I'm no longer using from the connector and solder it directly to the the X4R receiver so it looks like this. once connected to the flight controller, it's only a 4 wire connection, and the receiver is still removable if ever came a time I need to remove it. • Posts: 918 Threads: 83 Likes Received: 533 in 271 posts Likes Given: 498 Joined: Jan 2016 Reputation: 30 Love the detailed progress reports..
