  1. Hi Thomas, Thats the "veranda" video shot in rio de janeiro, brazil by "gabriel" and yes he is one of the most fantastic pilots I have ever seen. This video was posted on the rangevideo.com for a while as gabrial use a 1w 2.4hz rf/video system from them, the plane he uses is/was a flying wing/zagi-type(not sure of the exact brand). and he has more videos on youtube and hangs out in the fpv forum on rcgroups sometimes.. hope this helps gwen
  2. Hi all, I am the formerly proud new owner of A RANGE VIDEO 900 MHZ .5W SYSTEM, Unfortunately I wish I had looked the the specifications before I bought. As I am writing rangevideo.com to request an RMA. The problem is that rangevideo.com sells 900 Mhz xmitters and matching receivers with the following channel assignments, CH1 910 MHz CH2 980 MHz CH3 1010 MHz CH4 1040 MHz In the US ONLY Channel 1 is legal for usage even by radio amateurs, the 3 other channels fall within the license range allocated to the FAA for its Distance Measuring System(Video xmitters operating withing this range have been reasons for recent fines and penalties for some companies installing/selling video xmitters within this range,found those on the fcc.gov site.) I did write rangevideo.com via their contact form asking about this after I studied for and passed my US technician ham license but have received no response to date so now I will take the next step and request an RMA and start looking again for a 900 Mhz xmitter/rcvr with legal ranges. that I can actually use. comments on this most welcome gwen ps its looks like the mobicom stuff on ebay is almost small enough and I can get on legal 1.2ghz ham frequencies, and NOT piss off the same agency in charge of making FPV regs(FAA) by stomping on their in use frequencies. The SF Bay Area is FULL of FAA Flight aids with 3 major airports in close proximity.
  3. just sitting here awaiting my call letters gwen
  4. Thanx Sander! Would have helped if I had the right day.. spent so much time cramming didnt notice the test date was for the 28 not the 27.. now I can go through the question pool another 4-10 times:) wish me luck for tomorrow however a slighty confused gwen
  5. Hi Kilrah, I am sitting here waiting to leave to take the amateur exam at 9am, I changed my order on the 12fg to 50Mhz(ham band) more power and better range than 2.4 and much less chance likely of interfering xmissions in my area of operations. And will have a FMA copilot on board along with a OSD with a return to home function if this is not the paparazzi equipped airframe in case of carrier loss. Thanx for your timely advice Kilrah.(ie the warnings about the rfi issues with the royal EVO) and will be flying on pcm2048 on 50 mhz with 1w out gwenhastings
  6. Hi Thomas, glad u liked my little "trick or treat joke" for all those who havent gone to my "Location" ,its a tomb in the city of graveyards, Colma, California(ie one foot in the grave). my area of operations is from Oakland California, to Monterey and points south. I have several places I get to fly. All very dramatic, will post some video when finally airborne. cheers, gwen
  7. darn this is where the Kool kids hang out... count me in!!! hope I can contribute technically very shortly... very warm regards, gwen hastings - researcher ps we now return you to your regular noise level(s) after a fanboy has visited (although S/N ratio is 1000/1 in this thread except for my own postings) (humm I better pick up that 1/kw dummy load for 62.00 at HSC tonite or make my own out of a 200W power resistor, 4 quarts of silicone motor oil and a 1 gallon paint can + a couple of bits of wire to make a tank circuit
  8. Wow, You kids are doing exactly what I want to do, I am going to take my VEC for technician sat morning and was going to order a futaba 12FG 2.4Ghz FASST system but have been wavering about going a 50mhz rig instead and having an emergency amps just has been discussed here and from my reading of the regulations about emergency conditions it can be justified and used legally when the only other alternative is a loss of control of the model and possibly injury to people or property if that occurs. So even though the 50 Mhz version will take a few days longer to get here I think I will change my order now as I should have my call letters shortly and the competition for frequencies is a LOT less at 50mhz and the power issue + the range is farther and as VHF television goes away next year in the states the band should quiet(i believe 1 US channel is about 50mhz. The same cannot be said for 2.4GHz ambient radiation gwen hastings
  9. nope my video is on 900mhz, as I wanted to use xbee modems for paparazzi, and I am much more worried about errant RC signals at 72mhz while flying FPV ie I dont want to get knocked down by a parkflyer tx on my channel,so feel the need to go 2.4 , my only question is can 2.4 make the range for FPV. and additionally I have added a verdex gumstix with USB host,Bluetooth and wifi to my config so I can chat with the paparazzi Autopilot and an EVDO modem(we get over 1mbs here ). So the trackR1 will work with the 2.4ghz 12fg then? regards gwen(soon to be FPV pilot and soon after that paparazzi operator) ps I just got my sparkfun breakout board for the IDG-300 in today.. but will simply order a trackF1 to get flying immediately.
  10. So Kilrah , I wrote www.aeropix.ch, I assume that is the head gyro a lot of people use(It has a square futaba connector) asking if it works with the 12FG, as the Royal EVO has NOT been delivered yet I have emailed the vendor and will have the shipper return the unit to the vendor and have him send out a 12FG in 2.4GHz txrx combo instead(and will order the Track R1 in the same breath if you say this combo will work plug and play.) regards and thanx so much gwen ps going 2.4 ghz because of claimed range and lack of interference..(ie less liability from out of control craft due to interference) pss I am getting my ham license next weekend does futaba deliver the 12FG in 50Mhz(for licensed amateurs?) 16km? no problem at 10w
  11. ouch wish this had reached me sooner, went the evo because I thought it had more flexibility(I am a implementing a paparazzi autopilot/first be a FMA CDP-4) , and was under the impression that the evo trainer cord is channel selectable(I am implementing my own head gyro with an IDG300 for FPV with an ATMEGA tiny13 or a picaxe 8 chip). The EVO is going for 600.00 us and I couldnt touch the futaba for less than 1k(if you know of a cheap source for the TX alone(ie 600.00us) tell me I will pay the restock fee on the EVO)(BTW I just now checked the EVO 12 manual and found I can delegate up to 5 channels to the trainer cord) thanx gwen ie my headtracker is loosely based on this http://serge.laforest.free.fr/HMT/HMT.htm I disassembled the binary to see the algorithms and am reimplementing on a propeller prototype board in spin. and I that being said I searched on you and found you have done exactly the same as I am attempting and appear to be very experienced in this area. So what ARE your specific gripes about the Royal EVO?, Ouch just read your gripes about emi/emc from the Rf modules, and limitations on trainer cord I take it the futaba 12fg doesnt suffer from this limitation? which specific model do you recommend, (also keep in mind I need access to the ppm signal onboard the aircraft for paparazzi) and will chat with vendor tomorrow about taking unopened tx back in exchange for purchasing a system a 2x the price. (was migrating from CDP4 control to using the same sensor for paparazzi, with added z-sensor)
  12. Hi All, I am getting ready to do my first FPV attempt(s), have purchased a brand new easystar(will transfer the guts of my old E/S brushless setup, old airframe to be sacrificed for CNC /elapor machining experiments, finding the sweet spot for cnc/elapor) Video headset is a headplay unit, video tx is a 900mhz .5w rangevideo. video rx is 2xrangevideo 900mhz , 1 x 8db hyperlink panel to SMA male), 1 x 7 db omni(quad stacked collinear in a radome) both feeding a oracle video diversity receiver then into a belkin to ubuntu linux(recording) and into the headplay unit. I have a kx-131 with a pandora mount. I have ordered a sparkfun IDG300 breakoutboard(and using a french design http://serge.laforest.free.fr/HMT/HMT.htm) as the basis for my gyro driver for now until I recode in spin or c), I have at present an eclipse 7(but I understand this is hard to interface to a head gyro system where 2 airleron servos will be in use.(ie I am shortening the wings of the ES and flattening the wingtips and adding airlerons.)) will probably use an older futaba 8ch for my receiver but have a new berg 7P if that is sufficient(and much lighter) I am considering obtaining a EVO-12 to ease the head gyro interface. I will be using this design for my OSD http://forums.parallax.com/forums/default....x?f=25&m=202781 using one of hitt consultings usb propeller proto boards. from all the experience represented in this forum can the members tell me of any gotchas they may see with the setup(note the stacked collinear presents as a 4 lobed radiation pattern)(for those worried about circular pattern omnis. regards gwen . ps brushless is a rc-dymond EP 2800KV inrunner with a 7.5x5 prop(mounted in the can of a speed 400) powered by a TANIC 2150 3S1P.(yes the fuse is taken down to accomodate and CF rods and strips are being added during assembly to stiffen things up.
  13. Hi Mr Rc-Cam, and of course my question comes up about the hitt consulting propeller based OSD, that uses a missing sync detector chip also. will this work with the oracle? http://forums.parallax.com/forums/default....=181370#m181370 about half way down on page schematic in expresspcb as an attachment. will be hopefully ordering an oracle today gwen ps what about using a 900mhz 7db omni/tilted on its axis and a 900mhz panel as the 2 diversity antennas?
