Tired of replacing the motors after a few flights, (aka they have to work at full throttle to lift the 420 grams of the Rocket Drone), I've decided to upgrade them to increase the thrust.
After watching a video on YouTube, made by V262 Octaquad (who has replaced the V262 motors using the one installed on the MJX X101 Quadcopter), I found one on Ebay at just £19.99!!!
To remove the motor holders, I have done a-nearly-complete tear down of the quadcopter.
Regreattably, the carbon shafts/booms of the V262 are 4mmx5mm, while the ones installed on the X101 are 4mmx4mm, therefore using a 120 grits sand paper I've had to remove that millimeter.
(Please use a mask and a wet towel / kitchen paper, when you sand the carbon fiber shafts).
I've also replaced the Controller/Receiver, which in the X101 is positioned underneath the frame of the quadcopter, therefore it has to be mounted upside down on the support of the V262 Controller.
To do so, I've desoldered the motors cables from the motors and the LED cables from the PCB.
(If you prefer, you can keep one strip of LED, to see when the X101 quadcopter is bound).
Cut also the plastic frame around the controller of the X101 (please take a look at the picture).
In this way, using 2 zipties, I can attach it to the support of the V262 receiver (upside down), being sure that it has a bit of air to "breathe" (aka, the Mosfets become very warm during the flight) and that tightening the zipties to secure the X101 controller, I don't damage any electronic component. Last but not least, I've re-attached the cables to the motors.
Now, I have more power and I can afford to add a little bit of weight, therefore I've replaced the battery increasing its capacity to 1000 mAh.
