I received my order from Hobby King for green frame arms and green props, to help with visual orientation when I am flying. I should be able to spot the bright green front of the Quad. At least I hope so.
Also, I just received a really nice Multicopter simulator called AeroSim RC. It seems to be highly rated by multicopter fliers. While it doesn't have the high res graphics of many current flight simulators it has a significant number of different types of multicopters (Quads, TRi'd Octo, Hex, etc) as well as a few helicopters and planes. In addition to providing a good simulator it also has a training section. It walks you through several different training scenarios to improve your flying. I have tried a few so far and found it very useful.
Here is a video the provides some info on the product from an recent customer:
Now to the chopping...
When I ordered the four motors for my Quad from Hobby King, I "planned" to order the "short shaft" version of the NTM 28-16 1200Kv motors. What I received was the "normal shaft" version, which has a 1 inch 3mm shaft sticking out the bottom of the motor. I don't need that shaft, since I will be using a prop adapter screwed to the other end of the motor. And what is more important, the normal shaft won't allow me to be able to mount the motors in the frames, since they will hit the landing gear. So, the only solution, short of sending them back to Hobby King, is shortening the shafts.
I used a piece of aluminum plate I purchased at a local hardware store, drilled a hole in it just big enough to push the shaft through. The plates supports the shaft, acts as a barrier to metal filings and also conducts some of the heat away from the motor. I used a Dremel tool with a large cutoff wheel to do the cutting. It went very well and only took about 20 seconds per motor. I wrapped the motors in aluminum foil during the cutting to keep metal filing from the cutting from getting into the motors and their super strong magnets.
Here is a video I found on YouTube of someone using a similar process to trim their motor shaft. The major differences, I needed to trim a lot more off so the aluminum plate I used was only 1/16 inch thick. Also, I wrapped the motor with foil before I started cutting, to protect the motor from the steel "saw dust" generated by the cutoff wheel.
