  1. Loop brings up something I have wondered about. Does anyone here have or know where to find the output power specs for different manufacturers R/C Xmitters? I'm thinking like Futaba, JR, etc. I know I have seen one and I can't remember which it was but it was listed at 600mw output power. Thanks, Curt
  2. Thomas, Looking at all the pictures you have up and your club certainly needs to be congratulated on having such a good active participation. Love the pics and keep the videos coming also. Curt

    Dummy Load

    No he asked about an antenna dummy load. This is for testing an xmittr without effectively broadcasting a signal. There is no "measurement" inherent in a SIMPLE dummy load. It is only a load to absorb rf. With a purely carbon resistive element i.e. No inductive component as in a wirewound unit, and using connections as short as possible to eliminate as much lead inductance the load will work fine. The "things" will be so small that they can be overlooked. For testing a length of coax. 1. Why add a loss to the system with a hunk of lead in. And it will be a loss. 2. Any mismatch caused by the coax under test AND the insertion losses of whatever test gear is being used will greatly affect the ultimate signal matching results substantially more than any small inherent defects in the properly constructed dummy load. I have a DL here which I use to check and maintain my xmittrs it will handle up to a KW. If I had an SMA on the front of it instead of the 259 I could check the output of a 1w 2.4 unit with no problem....but WHY? C.

    Dummy Load

    Just use a 5W CARBON NOT WIREWOUND resistor. Solder your connecting leads close to the body of the resistor and cut off the excess leads. Do make the connections as short as possible to minimize the inductive tuning that excess lead length will cause. This will give you plenty of headroom for a 500mw, 600mw or 1W xmitter. The value of the resistor should be the output impedance of the transmitter antenna. ~50ohm. Use a .5 or 1% tolerance component and you are good to go. IF it is a RESISTIVE load the output freq makes no difference as it is neutral. Cost other than your time to assemble.....and not counting a matching SMA connector probably around 50 cents. Curt

    Fpv Videos

    I know this quote is from a while back but in case some may not know how to beat the megaupload/rapidshare type systems. If you have a internet link which you can break and reenable (DSL modem or whatever) AND if you are assigned a dynamic ip then you should be able to relog on and get a new ip addy. You can go ahead and dl again without having to wait for their imposed time limit. These systems log your ip so if it changes you become a different person...heh heh sort of anyway. Curt
  6. Yea this is what I feared. Like Mark said lots of 2.4G RF flying around. In real close proximity to other 2.4 equipment. I have no doubt the 2.4 aircraft flight radio system works fine on it's own. It was just what kind of effect the onboard video xmitr would have on the aircraft receiver. As well as on the ground the effect RC xmitr would have on the video xcvr. All in all I do like the idea of 2.4 operation for flight control just not if our video systems are there also. Will wait and see. If somebody does happen to run into someone at the field who has one of the new 2.4 systems. Try turning your video system on and see if you get interference from it. In all honesty I would expect hash on the screen if nothing else. Thanks, Curt
  7. Has anyone here running a 2.4GHz video system used or been running your video systems with one of the new Futaba 6EX 2.4 GHz systems also running? I'm wondering if there is any and how much interference between the 2 systems. I doubt the aircraft control systems would be affected due to the transmitter locking system used by the receiver, but would like to know if any interference in the video/audio has been noticed. Thanks, Curt
  8. Yea. You probably don't want to pay the price for a one up or small proto run etch from a PCB house. $$$$$ Since you are wanting to save money by building your own. I would say Terry's suggestion is the way to go. Curt
  9. Hey Rob, Thomas, I like all the experimenting which is going on here with the patch antenna. As well as with the lower end receivers. I use the plural since I have one also. Not the same brand as what Rob is showing here but the receiver can inside looks darn similar to the one I have. I have the patch pieces cut and ready to assemble, connectors will be here tomorrow. I will install the receiver connector in the same fashion as Rob. After pics and and a comparison of the junk dipole to the patch as well will follow.
  10. Uh isn't that Jeff Goldblum from his starring role in "The FLY!!" Heh heh. It would probably do the job but I couldn't take the ribbing from everyone at the field. Curt
  11. I sure would Denis. Any info you have on the vacuforming rig you use for making canopies. Thanks. I do have a question...Was there a canopy on the aircraft when you made the Bromont video? I ask because it sure looks clear enough that it looks like there was no canopy at all. No distortion or anything. thanks, Curt
  12. Denis, Can you put details up here about your vacuforming rig for making the canopies? Or would you be interested in making some and selling them to us other EasyStar pilots? It would be very much appreciated. Thanks, Curt
