Pulse proportional transmitter is working. http://www.youtube.com/watch?v=ih1w-nTu_Xg&feature=em-upload_owner The circuit boards will be positioned with component sides faced together. Next step is the receiver, super regen with low pass filter for the 400 Hz tone, so no tone filter as usually for me. The tone 400 Hz isn't "scaled" in the photo of the scope. On top the pulse, beneath the modulation with the tone, both signals of the pulser circuit board. The RF circuit is a copy of the famous Simprop 2 + 1 transmitter of the past. More to come. TF

Joe (PT19 flyer) and other readers, I received some e-mails from Joe about the construction of the Taurus and "slender look". Important to know is the slender look is mainly a matter... without the paint scheme. So Joe, if the Taurus on bottom looks slender, your construction probably... about the picture!

RE: Four channel tone filter radio
[b]Double simultaneous?[/b] For who is interested in radio systems. An important part of the (super regenerative) receiver is the detector of the receiver combined with the right filtering. The detector, combined with that right filtering does show us the tones of the transmitter, also the combined, two tones is needed, of a double symultaneous transmitter. The outputsignal of such a combination of tones is shown in photograph three. Signals are the down elevator and the right rudder signals which are separate shown in photographs one and two. When the shape of the signal is right both relais of tone filters are activated, in this case, to have right rudder and down elevator. Of course all combinations of rudder and elevator are needed (4) and possible. A German system also is to alternate the both tones a few times each second. With such a system more modulation dept is adjustable combined with higher level of sensitivity of the receiver filters, which can result in an expanded range. A second trick is, electronic cross linking of the tonefilters of each servo. The activated filter (relais) blocks his "partner" filter electronically. TF

RE: Four channel tone filter radio
Because original parts are scarce I did design a second circuit board based on silicon transistors. This circuit board for real practice use is more reliable and serviceable. The old board is for the museum. see second photograph. "Power" transistor is the "modern" 2N2219A in common emitter configuration instead of the AF118 germanium tranistor in common base. Both transistors were often used in the past. Modulation still with a hand made modulation transformer for collector and base mdulation, for the AF118, modulation was collector - emitter. Result of modulation is visible in photograph 4. There is also is also more power available. To do, mounting a heat sink! TF

RE: Four channel tone filter radio
Four channels so two servos needed I still do have my Metz (Germany) two channel servo of the past so a second was needed to complete the 4 channel, two servo radio. My choise was the Simprop Contest (analog) proportional servo converted for 2 tone filters. (Back io the future!). The limit- and neutralizing switches are mounted on the place of the potentiometer. Speed is reduced by a resistor. Some details to make the servo reliable, wiring etc, but he will do the job. Neutralizing is done by energizing the (second) tonefilters, Profit, only four wires are needed to couple the servo with the receiver. No tab is needed, the motor is energized by 4,8 VDC.

Four channel tone filter radio
For who is interested in radios. Transmitter of the period 1966, 27 Mc four channel,.picture 1, scratch built AM double simultaneous, so two tone generators. Circuit design was of Helmut Bruss, Germany!. The receiver is "new", finished these days, superregen and equiped with 4 tonefilters (Circuit design Schumacher, Germany) to control 2 servos. Total weigh 150 gram! The old receivers did evaporate in time. The relais are "modified", from an old microwave oven. Photograph 3 inside the transmitter. The case is designed to "store" 3 4.5 V batteries for 13.5 VDC. Currents draw 40 a 50 mA. Max current for the PA transistor, 30 mA!. All the brown sheet is "Pertinax" also the printed circuit boards.. Picture 4., amplitude modulation shown when one of the tones is activated. 1000 - 5000 Hz is used for tone filters. In the future the plane will be rebuilt. Photograph 5 is with the 2 channel and photograph 6 with the 3 channel. Now 4 channels! What a luxury! Hanna is proud too!! She always shows up with the result of a project, the QA employee. TF

RE: Dirty Birdy versus Phoenix 7?
[quote]ORIGINAL: countilaw Tim, It's not really that either one flies better than the other one.    Lets go back to the 70's when these planes were being designed and who flew them.   There were good pilots and then there were great pilots.   There were pilots that had deep pockets or sponsors that provided them with deep pockets.    These guys had the time to fly numerous hours in practise and had planes that were designed to do particular maneuvers better. And example would be the anhedral in the rear stabilizer. This was supposed to give the plane better knife edge capabilities, plus it looked good. When these pilots won or placed in the Nats, it made their plane more desireable.  It may not have been because the plane was a super plane, but that the pilot was a great pilot, mostly from the hours spent practising the pattern. All the planes, whether it was the P.6, Arrow, Magic, or whatever, flew well.  Other pilots liked the way a plane looked. The lines, shape, curves, and etc fit their idea of what a plane should look like, and they chose it and learned to fly it. [size=2][b]So, it's not that any one design flew better than the other,[/b] [/size] it's what plane fits your idea of what a plane should look like or what turns you on and how much you practise to makes that plane do what you want it to do. Frank AMA 8510 [/quote] Frank, not so romantic, It wasn't much different compared with the "real world"!

RE: What do you guys make of this??
[quote]ORIGINAL: Aurora_60 I had some time to start cleaning a YS 61-AR and found a weighted prop nut in the spinner. No big deal. I remember these a while back, but I think it wasn't too popular since you end up adding rotational weight to the engine that takes away performance. But this one looks different. For one, I cant find any numerical markings on it designating what weight it is. It was also really propped with a 12x13 APC C-2 on it. I'm starting to think that the weight was added to help keep the prop moving, but I dunno... What do you guys think? DM [/quote] Nothing sophisticated, just a weight to balance the plane. Costs, 3.49 bucks. Extra note: a killer for a pattern ship, that rotating extra weight!

My first plane 1966, after a period of controlline. Scratch built radio, two channel, Metz two channel rudder servo, so no escapement. The radio has tone selective filters . Airplane is of own design and engine a Webra 1,5 ccm diesel. The radio I used for a boat in the first place to try out, the range was enormous. Receiver was a superregen which I am rebuilding now, see the last picture. Second picture, 1967 Later the plane was equiped with three channel receiver and a one channel Metz servo added for motor control, two positions. engine Webra Glostar 3,5 ccm. One battery pack for the two Metz servos and one for the receiver. Tail wheel replaced for nose wheel. The transmitter is my second one and also a "bang bang" (Dutch tip-tip), so about 45 year old, double symultaneous scratch built and four channel. Now I am building a new four channel receiver. the coils are ready. The battery indicater is in the third transmiiter, my first proportional so must be replaced. All a matter of money. Last pictures, first proportional. own design scratch built. the last picture with the first ailerons. Cees

RE: Classic Pattern Engines Available
Yes Joe, a fuel pressure regulator. Reference pressure is taken from a sensor tube near the air inlet of the carburetor to create a setpoint for the fuel pressure regulator at the same value as the air inlet pressure of the carburetor. It's a method to eliminate the influence of the hydrostatic pressure differences and G-load caused by attitude of the plane and location of the tank. Only difference now is the distance between the centre of the regulator and the spraybar of the carburetor. Picture made from another position does show the reference tube. Temperature measurement of the glowplug base is done with a thermocouple and the cold junction is mounted on the regulator. This has advantages for the cold junction temperature compensation. Cees
