This is some sample video taken with the HD 808 keychain camera attached to my Hobby King EPP FPV RC model plane while on a 1.3Km journey across the New Zealand countryside. Also onboard was a Hobby King 900MHz video system modified to operate on NZ-legal frequencies. Unfortunately the RF output of the HK video transmitter is rich in harmonics that cause the 2.4GHz RC receiver to be significantly desensitized, limiting the pracitical operating range to not much more than 1Km. By comparison, I have flow the FoxTech 200mW 5.8GHz video system out to distances in excess of 2.2Kms.
Two mods being used in conjunction. A redstone “plus” if you may, and Radio mod. Redstone by Pixelkids www.minecraftforum.net Radio mod www.minecraftforum.net Im using the first version of Radio mod, because in the newer versions it has radio transmitted doors, and TNT and other things, in which I do like wiring my self. Also, this is the direct Fraps AVI of the video, instead of a coverted WMV. I may do this for a while, maybe not because it takes a good 30 minutes for these to upload. And I dont like having 1gig per video sitting on my laptop.

PLEASE SUBSCRIBE : D Capo, Picks, and Wireless Transmitter – All in one! Here’s a really quick cheap and cool way to play your guitar on an amplifier (even on your car radio, tailgating anyone?) using nothing more than a wireless guitar transmitter, a FM radio, and a few audio jack adapters. Easily works up to 15 ft. Professional wireless guitar transmitters can run up to 400 dollars, and this costs less than 10. Sounds like a pretty good trade-off to me.
We installed a security camera at our business for about a year, I feel like I constantly have to be checking it and it replaced my normal viewing of television and radio. If the system goes down, I get anxious and scared that I don’t see what is happening. I can’t read or do any other work as long as I hear at least the white noise from the security camera then i am ok. I could be enjoying myself by listening to music, but no I have to hear every word they are saying. It’s taken over my life and I can’t turn it off. Anyone else has this experience?
Tetsuo Kogawa performs with his simplest FM radio transmitters.

See servo failures, UBEC testing, and HK Orange Receiver Range tests vs Spektrum AR-500 Receiver while Range testing with my Turkey Baster Can. Then see the full range testing in the car. Typical Range of the Spektrum DX6i Transmitter is approx 3000 feet and with that test it resulted with the following relative formula. 5 feet from the can equaled approx 480 feet 10 feet from the can equaled approx 793 feet 15 feet from the can equaled approx 1156 feet 20 feet from the can equaled approx 1780 feet All 3 of these HK orange park flyer receivers are flyable, based on these results. However, I do not have faith in the Hobby King Turnigy servos for this plane, so reverted to some good old (made in USA Kraft KPS 15 II Servos) The HK UBEC has been working flawlessly, however a 4.8 v receiver battery would be less likely to fail than this UBEC using a 7.4 LiPo. Stay tuned to see the building tips of the PT 19, engine starting, and flying.
