Generally I try to make positive posts and although this may seem negative, there is some positive in it. Windows Password Unlocker found on passwordunlocker dot com is worthless. They claim it is free and that you have a free trial but they fail to mention that there is no trial at all. You waste time and a CD/DVD burning their advertisement and that is it. If you want to have more than an advertisement then you must purchase the likely useless software and then waste yet another CD/DVD. Stay clear of passwordunlocker dot com and their Windows Password Unlocker. It is best to create a password recovery disc when you purchase or install your computer. If you have not done so yet you should do so this minute. If you have not done that and you have lost your password then there are a number of actual free applications that do exactly what they say they do. You may want to look into Ophcrack, Cain & Abel, DreampackPL all of which I have tested and found to work exactly as they suggest. If you download and burn Windows Password Unlocker be sure you have only wasted your time and your CD/DVD.
The 3 blade props found on GWSProps.com have so far been the cheapest 3 blade props I have found for the quadcopter plus both their s+h prices and times are very reasonable. Overall for the price you cannot go wrong. They use less power while providing the same amount of thrust as larger 2 blade props and they are only an advertised 10 grams a piece. The quality of the blades seems to be a bit inconsistent but this may be at least partially due to packaging used in shipping. The plastic props are breakable and ship in a padded manila envelope though none have come in broken out of three orders. I have found a number of prop blades to be bent upwards on one or two of the three blades and at one time had only noticed it on the HD-9050Rx3′s but it now just seems to be random. The weights vary slightly which could be fixed easily by sanding or filing little by little off the top and bottom of the center hub area until the weight matches your lightest prop and then repeat for the rest. I actually use a dremel for this which makes it much faster but you must be very careful or you can easily shave off to much.
My findings for prop weights from a few randomly selected props from 2 orders.
9x5x3 10.3g, 10.1g, 10.0g
9x5x3CR 10.7g 10.5g, 10.3g
9x5x3 10.3g, 9.7g, 9.8g
9x5x3CR 10.7g 9.9g, 10.1g
I have also noticed that not all of the props are marked GWS and the plastic is different. This is for both black and grey props and I have yet to find one grey prop marked GWS. I really have not compared the blades for durability but I am guessing there should not be a great difference as they feel roughly the same and after all they are only $2.00 a piece and are more than sufficient to keep the beginner supplied.
