QX90 Upgrades

In this video I take a few performance parts from Banggood and show you how to install them into an Eachine QX90 micro quadcopter! You can also use these upgrades on any micro multirotor of your choosing! The stock QX90 comes with two 1s 600 mAh lipo batteries and motors that can only handle 4.2 volts. I wanted more power and Banggood hooked me up with everything I needed! I try out two different sizes of 2s lipos that deliver 8.4 volts to determine which is a better fit for the QX90. The new motors can handle the extra voltage and have a considerable amount of extra power at 2s or 8.4v. I test the new motors in my test stand and compare thrust measurements with the stock motors. I also show how to solder all the new motors in place and how to change the 1s to 2s jumper on the F3 Evo Micro flight controller so it can handle the higher voltage lipo packs. The FPV camera and transmitter can no longer be soldered directly into the battery terminals because of the higher voltage so I use the DSM port on the flight controller and use the 3.3 volt and ground terminals that are regulated. Soldering the buzzer is easy because the F3 Evo Micro fc already has designated terminals for it and I like having the audible signals for low voltage or if I loose the QX90 in tall grass. I would have liked to use the parrot propellors because out of all the props I have they provide the most thrust but the QX90 frame is not big enough to accommodate them without modifications. The stock/ Hubsan x4 props are the best option but I only had ladybird props that would stay on the motors for this video.
