Mods, or modification, is taking any stock item and converting
it to the point of coolness. We modify everything, sometimes
without regard to time or money things we take interest in, be
it computers, cars or even our toys. The AR Drone is no
different, owners add legs, stilts, LED light arrays, cameras
and some have really cool paint jobs, there is NO limit to what
you can do to your drone.
To us modders, we don't acknowledge the warranty,
especially when it comes to the drone! The biggest reason is
that Parrot has made available every part and special tools for
sale. For a reasonable price, any broken part can be replaced
using the online YouTube tutorials Parrot has created.
This is a simple yet important mod. The motor assembly is comprised of a precision electric brushless motor attached
to a controller circuit board. The controller board both supplies the motor with power while communicating with the
motherboard. This board is coated with a water resistant, non-conductive substance. Parrot realized that enclosing
the assembly with a protective shroud and adding unnecessary weight was not the answer. The precision motor
armature is a very strong magnet and can attract extremely small ferrous (iron) particles, or magnetic dust .
The only way for debris to enter the motor housing is through the two small holes located on the bottom end facing
the ground. One way to tell if debris has entered the motor housing and stuck to the armature is by feel. If you
finger-spin the props (you should after each cush landing) and there seems to be something stuck in the plastic gear,
clean it out. If both gears are clear and resistance is still felt, there maybe garbage in the motor, if so, you will have to
replace the motor assembly. Attempting to operate the drone with a bad motor you will get error message and the
drone won't go online. For future peace of mind, the following solution is easy to perform.
Guaranteed, after 40 (forty) flight hours, or the total amount of time your drone has been in the air, your drone will start to get wobbly,
constantly twitching, making small adjustments while in hover mode. At times your drone just doesn't act right. So check the side play on
the prop axles. I doubt Parrot realized that what they ordered from the manufacturer is NOT what they got when it comes to the Prop axle
bushings. Advertised as "self lubricating bronze bushings", these bushings are not bronze or even a red metal but cheap copper plated
steel inserts and they don't last!
Creative drone owners are replacing those inserts with sealed ball bearings, a recommendation if you plan to fly for many seasons. If you
do replace the inserts, keep the bearings should your central cross break, simply move the bearings to the new replacement cross.
If you're like any other drone owner, you'll want to get up close and personal with that flyer while hovering. And if
you're like any other pilot, you have and ended up getting your fingers whacked by the spinning, almost invisible
propellers! Play it safe and paint the tips of those spinners. Use white or yellow TESTORS paint. Mask off where you
want the paint to stop and apply 3 coats. 3 coats will bring out the brightness of the paint over the black plastic.
Place a piece of tape on the end at the same angle as the tip, then place a piece next to the first one, remove the
first one and paint the tip. Repeat on all props the same way and it'll look professional !

To remove the old bushings which are 2mm thick, stick the axle into the bushing
3mm (not allot) and twirl the axle around using a little pressure or resistance, and
the bushing will walk itself out of the hole. This is possible because the
manufacturer only pressed them in without an adhesive. Do this to all bushings
both top and bottom.
The replacement bearings are 2mm X 5mm X 2.5mm and can be found in hobby
shops and on the Internet. The average cost for a pack of four is around US $4.99
plus tax and shipping. Amazon.com is the best place to order bearings and even
parts for your drone, and they have a return policy as well. Once the bushing is out
simply push the new bearing into the hole. This operation can be performed with
the motor assembly in place. REMEMBER, you will be working close to the
controller board, be careful NOT to scratch the board or knock components off. It's
simple and shouldn't take more than a 45 minutes to an hour to complete.
After all new bearings are in place and you have sanded off the little nubs from the
large gears you can re-assemble the prop/gear/axles. When completed, finger
spin each prop, if any don't spin freely, remove the prop and gear, re-sand the nub,
re-assemble and test. Click here to see the vid.
