T-Motor MT2216 900KV Version 2.0 high-performance brushless electric motor for multi-rotor aircraft

Tiger Motors T-Motor MT2216 900KV is a high-performance brushless motor specifically designed for use on multi-rotor aircraft such as quadcopters and hexacopters. The all-new Version 2.0 of this motor now features EZO® Bearings from world renowned Japanese bearing manufacturer Sapporo Precision, Inc. Built with precision workmanship, T-motors are smooth running and well balanced right out of the box. This cuts down on vibrations that can negatively affect aerial video and autopilot inertial sensors. This MT2216 900KV motor is recommended for use with 3 to 4S LiPo and 10x3.8 to 11x4.7 props. See photo library above for detailed spec sheet and dimensional CAD drawing. T-Motors are backed by a two-year manufacturer's warranty on materials and workmanship.

T-Motor MT2212 980KV high-performance brushless electric motor for multi-rotor aircraft

Tiger Motors T-Motor MT2212 980KV is a high-performance brushless motor specifically designed for use on multi-rotor aircraft such as quadcopters and hexacopters. Featuring Japanese-made bearings and precision workmanship, T-motors are smooth running and well balanced right out of the box. This cuts down on vibrations that can negatively affect aerial video and autopilot inertial sensors. This MT2212 980KV motor is recommended for use with 3 to 4S LiPo and 8x3.8 to 10x4.7 props. See photo library above for detailed spec sheet and dimensional CAD drawing. T-Motors are backed by a two-year manufacturer's warranty on materials and workmanship

SecurityCamera2000 CMQ1993X SONY Super HAD CCD 600TVL D-WDR DNR Board Camera For FPV

Only 8 of these most popular FPV cameras from SecurityCamera2000.com, now with IR filter, are available in our shop, or by clicking the photo to amazon.com's product page:

The most popular FPV camera from SecurityCamera2000.com, now with IR filter. This is a 600TVL FPV board camera with Nextchip 2040 DSP, Samsung and Panasonic resistance components, and a Tantalum capacitor. It is installed with dual 850nm IR filters which block IR light, providing true-to-life image colors. This camera is very suitable for FPV. Mavbot has also added the DIY filter kit so you can run your camera and video transmitter off your 3S LiPo without needing a separate battery. Kit contains a diode to reduce voltage from 3S LiPo to the range required by the camera, and a 105°C 330µF capacitor and ferrite ring you can use to make a filter to remove the interference lines from your motors and ESCs. Solder your V+ to the camera thru the diode to drop the voltage, and solder the capacitor accross V+ and GND (the stripe on the cap and diode is the negative side). Wrap the V+ and GND power lines to your camera and your video transmitter through the ferrite coil at least 5 times.

Beware of Prop Hub Cracks

Tip: Be sure to remove your props and inspect them carefully for cracks from time to time; especially after a crash, or even a seemingly minor prop strike. The DJI Phantom prop below doesn't appear to have suffered significant damage aside from superficial scratches (it hit a lightning rod at high speed, and the copter recovered attitude and continued flying without much of a hiccup):

Figure 1: This yellowish line on the DJI Phantom prop hub is finer than a hair and nearly invisible.

But notice the faint yellowish line on the prop hub, even finer than a hair. It doesn't look like anything to worry about, but apply some slight tension, and it becomes clear that it's actually a crack that runs 90% of the way across the hub:

Figure 2: Applying slight tension to the prop hub reveals that the fine line is actually a severe crack.

This crack will expand over time, until it reaches all the way across the prop hub. At that point the entire prop will likely break in two during some high throttle maneuver, and the quadcopter will fall out of the sky, perhaps to be severely damaged or destroyed on impact.

So I advise to remove your props regularly, and check carefully for hairline cracks, especially in the hub area. And after a crash or prop strike, check the props before flying again, and replace any that have even small hairline cracks.
