    UAV Design

    Hey, I am currently working on my UAV at the moment on cad, I just wanted to ask a few questions about my selection. I have choosen to use a pusher design, similar to the X-45A, with a butterfly Tail mounted with a Yak130 type wing. I hope to bury the engine between the butterfly tail with the forward air intake being used to cool the engine and muffler. Also does it matter how far away the two sections of butterfly tail are away from each other to be effective? As I hope to mount the engine between them, so there will be a gap. What do you think? http://www.air-attack.com/page.ph

    Elevator Throw

    Erm... I don't quite know how this did a double post :/ Mod, Please delete witch ever one is in the wrong place.... - Phil
  3. Hey, I have a wee problem with my trainer, I have spent about 3 hours setting up my elevators on my trainer after the metal rods that where supplied with it, snapped after one bend SO I had to buy more metal and rebuild the elevator. At the minute I am trying to find out just how much "throw" you lot have, and I was wondering if the throw on my aircraft is ok for learning. I get about 8/10 Degrees throw Down and about 15/20 degrees throw up, I hope it is alright. Sorry if I posted this topic in the wrong section. - Phil
  4. Oh I see lol I have gone for the GAS option, rather than the electric one, range being one of the main factors in that, although, trying to hide the bloody muffler is a complete and utter pain in the ass. Why if I may ask, Electric? - Philip
  5. Greetings, I was wondering if you folks have had this pop accross your head in the past when it came to designing your respective UAV Camera Ships, I suppose that to a limited degree the ones that support Security Forces would be more interested in this thread, but I was wondering if other members have just "styled" a stealth UAV or merely tried to quiet your UAV down to a whisper.... Thanks before hand for your replies. - Philip
  6. Hey, Thanks for your replies, I was wondering where you could buy the Y cables, preferably in the UK or if a UK link can't be found or known, could you pass along the link of the US site that supplies, I apologise for the rather stupid question. - Philip
  7. Hey, I was wondering if you folks have ever had the problem of having only 6 channels on your reciever, and only 2 channels spare with about 7 things you want to control? Well I was wondering if it is possible to hook up two or three servos together into one slot, aka hooking them up so that one channel controls those servos. Basically at the moment I want one of my channels to drop my flaps and tail hook together at the same time. I am sure you have hooked up more than one electrical applicance to one plug, because you only have one wall plug in your room. Can it be done, any sid
  8. Hey, I am glad I could be of some help, the pilot tube seems like a rock solid idea, your right in relation to the small movements in relation to RC aircraft aerodynamics, with a vane you would get a more "correct" reading, as the airflow wouldn't be spoiled by the aircrafts structure. I suppose it could be set up so that if your RC aircraft has Telemetery, you could set up a very simple algorthm so that once the aircraft goes to a certain angle of attack, using the vane, and then an a predefined airspeed, the telemetery could start screaming... Some "Bitching Betty" promps would be
  9. Hey, Well... if you cut a hole in the leading edge and put a thick bit of card board or metal flap in a tunnel with in the wing, with a button and part of the flap overhanging the button, as the airspeed increases the flap will hold down the button and disable any warning device you want use, as the airspeed drops off or the angle of attack reduces the airflow within the cut out tunnel the flap will release pressure on the button and the stall warning will go off, you just have to tighten or lossen the flap hinge as required so that you know the stall speed of the aircraft. I hope this h
  10. Hey, My first draft design had to be dropped sadly, it looked too close to a TLAM lol erm thats a Tomahawk Cruise Missile if you don't know that stands for. At the moment if you are interested I can scan in a few of my drafts and post them up here. At the moment the UAV Autopilot system will imploy the same systems that you folks use to move servos etc, with the addition that the GPS unit will be hooked up to the PDA also, providing a means to change the waypoints on the fly. I would love it if you could tell me the parts that you use in your autopilot and if I may be so bold as to
  11. ::coughs:: Beyond the range of a student! lol Wonder if they give out 30 day free trials... lol
  12. Hey Terry, I do apologise for my spelling mistake, the hall unit should read HAL, I was in a wee bit of a rush to get myself out the door for work. ::nods:: I have a few books on RC aircraft and all of them agree that the linkages are rather important and should more with very little resistance, if the aircraft is to surive longer than the time it takes to hit the ground from 5 ft up lol I am going to remove the rods and see about getting the wire fixed up. At the moment I would consider the HAL unit nothing more than a Gyro, as it doesn't change course in relation to a predifined r
  13. ::interesting:: I was wondering what the price range for each of these units would range from? I wasn't able to find a price on the site. - Philip
  14. ::nods:: At the moment I have had to mount it under my Trainer, but to be honest, I am unsure just how successful my trainer will be at the moment :/ I have had issues with the elevator rods, they do have a full range of travel, but there is a good bit of resistance to it, I may have to pull it apart and straighten out the rods sadly :/ Although the trainer isn't of much importance, in the grand scheme of things, I had hoped that it would get my skills up, so once I finsh my autocad UAV fuselage, and build it, I could fly it... It the minute I am going to mount the hall unit in a ne
  15. lol At the moment I am a wee bit unsure of its sighting location, between the undercarriage and then the crash prone area for the newbie, aka the belly so I was wondering, where did you mount your optical unit? On the underside of ontop? What do you use it for, just general flight or camera ship? - Philip
  16. Terry, If I may ask, what are the results from the unit, Steady flight? Okish flight charactristics or a pain in the ass, any tips for me? - Philip
  17. I thank you for your quick reply, I have noticed that too, well I will be sure to let you know if I fry it - Philip
  18. Hey folks, I apologise if I have posted this question in the work section or that I shouldn't be asking you folks without introducting myself. Well I can solve one of those problems I am Philip, current resident in a retirement town, deep in the boonies of the UK, I am interesting in the prospect of developing a UAV system, sadly my knowledge is limited to computer construction and Computer C++ and visual basic program, I lack knowledge in relation to the programing of the chips that I have seen many mention, so I decided that to get into this subject, I should jump in at the start, wit
