Re: [RCSE] Royal Evo
Hi Barry, Just received mine with a HF-synth-module instead of those old crystals.. I couldn't find the time to configure it though, but it looks great, is very handy and rather liteweight. There are still some switches that potrude from it, so you still need a case. The software seems to be very intuitive. A friend got it the same time and he configured it and said that the hard part is to make a setup-template according to your habbits and then it's extremely easy while giving you alll the freedom you could ever wish to (there is a instruction-PDF you can get at their website that tells everything)... Looks a lot better than those robo-cop-style-JRs (beauty is in the eye of the beholder of course), has four flight-phase-memories for each model and costs a lot less than the Graupner-JR TXs (479,- Euro including 16% VAT with the Euro-$ being 1:1) I tell you more as soon as I configuered mine... ;-)) Cu Wolfram Has anyone been using a Royal Evo? Checking the archives, there has been a bit of a buzz of late. Web site indicates they are being delivered. I'm curious to know if anyone has had one in hand and how it stacks up against the Profi 4000 or a Stylus.

Mostly, though, I think that something like this: http://www.futaba-rc.com/radios/futj9000.html should be the standard in computer-driven Tx hardware interface (not all 9 channels of it, though; I usually need 2 and sometimes 3). I was just talking to a guy yesterday, though, who was completely stumped by his, which indicates a failure in interface design. He was new to the hobby and was getting pretty discouraged about the whole thing just because he couldn't figure out his radio. So the software interface, I think, has to change. For instance, imaging setting your centers by positioning with the stick and then pressing the Center here button. Then setting the endpoints the same way. To get a Launch Mode, align all your surfaces the way you like them, then press Enter and it moves the centers for the program to the appropriate spot. You can then tweak expo or whatever for Launch Mode in the same way. -J d. o. darnell wrote: The concept of graphical user interfaces (GUI) for programming TX's might at first seem like a good idea.

But, here's my layman opinion: For most guys no. I don't think it's usually worth doing it. Which is why much of the time a builder will just stick with constant chord surfaces. It' tough to argue with the convenience of commercially available materials. However, on a speed plane (depending on control surface rigidity) it can be an important factor in avoiding flutter. On an earlier plane, I had a problem with both flutter and a pronounced tip stall at full throw. I'm trying to fix that. A tapered aileron would seem to fix that. -J And, is the effect noticable? For most guys no. Personally, I like lots of roll authority and tend to over size mine any way. But I don't fly speed planes so my sloppy building doesn't risk flutter. The choice of control surface width is very complicated. But a ballpark value is usually good enough to achieve decent performance. Which is why I originally said 25%-30%. They're commonly used values that do fairly well. To examine the subject more closely, we'll need to consult the likes of Blaine, Joe, etc...

RE: [RCSE] RE: GUI programming for TX's
My feeling is that the PC should not be relied on for all the programming but make it easier to do the intial setup. I feel that a good UI is the key. I would give up the idea of PC pragramming ability if the manufacturers would make an easy to understand UI. it is difficult ti have to burrow through choices to get to where you want to be when you have multiple paths to start from. Unless you are really familiar with where something is you have a heck of a time finding what you need. Why not a flow chart and choose what you want to from the chart? Or a menu driven system? On my JR I have to either hold down two buttons on power up or hold down the same two buttons after it is powered up to start down two seperate paths so I can scroll through the choices. Then there are two ther buttons you can press for more paths. I realize that this is kind of old technology these days but I feel it is time for the radio mfg's to make this easier. As for a market or lack thereof, for sailplan flyers, probably no. But what about the other radio control flyers out there. I am sure the TOC guys would find it helpful.

[RCSE] SuperZ For Sale SuperDuperLow Price
For Sale SuperZ Airplane Previous owner says it flys ok Weight is between 35-70 oz give or take 10 oz I'm told it won't break if you winch it Has had it's fair share of repairs but all parts are there 4 servos included. 2 are name brand, the other two servos are a mystery. You must by the plane without knowing what they are. I too fly a Super Z and they are great planes. I won't fly this one though because it's too ugly, has had too many repairs, needs too much work to make it fly, and my friends might see me try to fly it. Comes with the wings. The wings make this plane fly much better. Comes with the V tails too, when added with the wings this plane flys great... so I'm told. As an added bonus I'm not cutting off the wing connectors but will leave them intact so you can plug them into your rx before you launch this on a winch. Even with all these repairs, it should go up on the winch. This is a rare airplane. Act now! Once you crash yours, mine will go up in value. Don't pay attention to those other SuperZ's out there. This one is a deal you won't find anywhere else. Ahhh nebbermind, I'm putting this on ebay. If the bids aren't high enough, I'll cancel the auction and post it again for sale here over and over.

Re: [RCSE] You gotta REALLY wanna do this!!!
Has anyone here given thought on this thread that controls stick position at the transmiter doesn't really tell you anything at all about actual control throws at the surface of the model? Linkage, horn length, slop, flex, servo type and other variations wilklhave an effect on actual throw. If you want to do this, rig something to actually measure throw in angular units verses transmitter movement in angular units. ATV in numeric units ??? thats exactly what i proposed to do at #2: to pick up the actual input signal vs control surface deflection graph using computer. all the graphs that are drawn later, when you are creating a setup for TX (at #4) show actual control surface deflections. or percentages don't tell a lot, and variations in models and installations will present different throws for the same transmitter inputs. I think the idea is neat, but I don't think it will really make it as it's gonna be too costly and complicated to be available to the limited user base, and results won't be guaranteed. one thing i forgot to mention: the market for this kind of system is really small. if this is done commercially it will die sooner or later. i believe that open source project of some kind would be much more successful and useful for everyone. arne 1) it is possible to build a very cheap computer controlled multichannel servo signal coder/decoder using some microcontroller chip. RS-232 would be a cheapest way to connect it to PC. 2) you hook your plane to this device and measure the control throws of all control surfaces. perhaps not just min, center max but at more points, to get more exact response of the control surface to input signal. computer will drive the servo and you manually measure the deflections (i think that automatic measurement would be too expensive to implement). this is one time job. 3) a software model is created for every TX. the model captures the programming model of TX and all it's capabilities. creating a model is big work and must be done by someone who throughly knows the TX. of course: if the manufacturer is cooperating, it's much easier. (the model captures only behaviour of the TX, the user interface, programming and communication is dealt later). the abovementioned device can be used to measure the exact charcteristics of the TX: you hook this device do your receiver, move the stick to some particular position and let the calibarating program to measure the servo signal. you can pick-up exact characteristics for differential or whatever you need. 4) the model of the particular TX is realized as a plugin for a bigger programm that can be used to program your TX. the programm provides unified user interface for all TXs: with sliders, knobs, switches, sticks, whatever. you can select TX model and create various setups for it, compare setups (graphically), store them to file on PC and so on. this programm can drive the servo signal encoder described above, so you can test the setups on your plane. if you want to transfer your setup from one TX to another you can compare the output graphs of setups from different TXs and alter the parameters of the destination TX until you achieve a similar output graphs. since you have measured your plane (on step one) you can observe the real behaviour of the control surfaces. 5) the programming instructions can be added to the TX model. so if you are satisfied with your setup, you can print out detailed programming instructions for your TX. or you can re-create the model in your computer by following the programming instructions. this can be done for every computer radio. advanced options: 1) if the TX has a PC interface and if the format of the programming data is known, one can create additional (different) plugin for this TX that handles the communication and uploads/downloads the configuration to/from TX. this plugin cannot be created for all types of TXs, it's not that universal, it might even be platform-dependent. 2) add some automatic conversion function that will try to convert setup of the one TX to another (using neural network or something like that). arne RCSE-List facilities provided by Model Airplane News.

Re: Blue screen sandbagging, was [RCSE] GUI programming for TX's
Oy, now you're talking about actually *controlling* with the computer? I mean, that would be fun, and it's definitely possible, but that's some wicked klunky. In that case, I think you'd want to start with a Palm and write a custom app to talk to a custom-built Tx module with sticks for input. All possible, interesting, difficult, and expensive. i added a mixer to my hitec focus 4am transmitter. the mixer is an analog computer. when i built it i looked at the possibility to build a PIC based digital computer instead. the problem was a DA converter. AD converter for sampling the stick positions is very simple. microcontrollers with sufficient number of analog inputs are available and cheap. at that time i found only one microcontroller that had a built in DA converter. it's certainly possible to create small addon board for simple non-computer radios that would sample the stick positions, send the data to PDA using RS-232, receive the processed data and send it to transmitter circuit. imagine: you can record your manouvres to PDA and replay them later :) only one thing bothers me little bit: reliability of the software. some kind of emergency cutoff switch for fully manual control is probably required to save your plane when PDA crashes. arne RCSE-List facilities provided by Model Airplane News.
