Hi guys and welcome back! In this article we build a 200mm X-Frame quad-blade racer & go out and maiden it. We also crash it hard during the maiden thanks to your carefree pilot ;-). As always, a complete shopping list with all used parts is given below.
Let’s get started. This is our frame, the RedPawz 200-size frame for 5’ props. Build quality is awesome on this, without noticable flex in the arms.
It’s also pretty lightweight – the bare frame is only 74g when put together.
Here are some detail images of the bare frame, it features a typical x-frame buildup in the middle.
For motors we use the AOKFly 2205/2300 motors. Those are really awesome, very very smooth running motors and plenty of power. I’m also really impressed by their build quality.
As a flight controller we got a cheap F3 based flight controller here, which does actually look quite nicely manufactured once you get rid of the cheap packaging, as you can see in these detail shots. Unfortunately it has a little surprise to it, which we will come to a bit later ;-).
As a PDB we use a new one by Diatone, which comes with an integrated LC filter, which is quite nice and works great. Video is totally clear.
As an ESC we use the LittleBee 20A 4-in-1 ESC, which you can see here. I always wanted to try it, since it makes building much easier and also cleaner. Since I’ve had great experience with the normal little bees when it comes to durability and peak amps, I have great hopes in this one. So far it’s working great.
On top of this we have our F3 flight controller, which you can already see connected here. Buzzer on bottom right, RC-in on the left, voltage-in als on the left and on the bottom I’ve already soldered the ESC wires. Here you can see the complete setup, including the RunCam Arrow FPV camera and a cheap Eachine video transmitter, which has been working great for me. You can also see how easy it is to connect the motors thanks to the 4-in-1 ESC, that’s a real benefit of it.
Here comes the surprise regarding the flight controller which I promised you before. On this one the buzzer connector is soldered wrong! So to get the buzzer working you actually need to solder th wires on the bottom directly. Easy, once you know that you have to do it.
For mounting the VTX on top of the flight controller, I printed myself one of my easy stacking plates, which enables me to mount the VTX nicely.
Almost ready now. We just mount the RunCam Arrow and screw in the top plate, which also has a nice action-camera mount.
Here you can see some more photos of the almost finalized quad and … here it is with those sweet DAL quad-blades attached. Those look really sweet and give a great punch, even on 3s. The FrSky receiver which you can see here is a lightweight, FrSky compatible receiver by K-Servo, which I have been using in many of my newer builds. It’s cheap and works great.
Total weight of this frame without the lipo is below 300g, which is pretty awesome as well for a 5’ copter, I really like to build them light.
But now, let’s continue the fun, it’s time for the maiden
Maiden was awesome. I maidened it with 3s and even with that, that thing has plenty of power. Enjoy the maiden and make sure to watch till the end for a nice crash ;-).
Man that was a ride. Result? Just a few broken props. That frame and equipment can sure take a beating. My conclusion? Love it. Awesome copter and can’t wait to fly it again.
