  1. I made this I am getting it ready available as a kit There is a whole thread about it here: http://www.rcgroups.com/forums/showthread.php?t=1564878 That camera turret was inspired by this very expensive product (4000 USD):
  2. Hi The autopilot set up is so easy. The goal is in an idea that struck me one day. Speed hold. We measure the difference between static and dynamic pressure. All of you understand how this works. On the plane we have the Pitot tube, from where the two pressures are lead to the engine servo interface (Speed Hold). It is a board where two pressure sensors are integrated along with electronic that tells the engine servo what to do. It works in this way: After take off you fly the model at a requested speed. Then activate the speed hold by a switch from the transmitter. By another proportio
  3. Hi everyone. We have rebuilt the RCAP as I promised. It is now working much better then the original RCAP. The main fault with the old one was that the servo kept the rudder position for only 1/10 of a second. Then the servomotor stayed without power. If the plane was fast, the wind would blow down the rudder in to the center position. That was the trouble. Such a fast plane would not be able to turn. Our GPSNI (GPS Navigation Unit) keeps the rudder under power all the time. There is another success. We built the speed hold and ALT hold as wel. Our acrobatic plane is able to travel on a pred
  4. Hi Terry I have made power point presentation regarding the arrow pointer. Where do you want me to post it
  5. Hi Thanks a lot for the replies. The reason why I chose this plane is as it is fast, big, can carry some payload and a lot of fuel. Copilot handles it very well, even the rudder driven by RCAP is fine. I shortened the linkages and it is fine now. It flies 50 - 70 Mph. I am a licensed pilot. I fly ultra light planes. When all is ready I will follow the model plane on a route by a real plane. The model must be fast, otherwise I could not do it. It might happen, that when it arrives at the final point, it is so fast, that the reaction to the rudder takes some time, and before it actually start
  6. Hi Rcap has its imperfections. Have you read my report about RCAP testing? There would be the answer to most of your questions. I am using Garmin E-Trex, Acrobatic plane with a 2 meters wingspan, The trouble is not the pots. The trouble is the behavior at the final waypoint, and the servo handling when RCAP is on board. The servo works in jerky movements. Have you noticed? So far guys, it looks like no one here has actually flown the device on a route that ends with a destination waypoint. I am going to solve my problems in this order: 1 I will reprogram the chip with a file that rad
  7. Nice you found domething. We are interested what it is
  8. Well as soon as it gets to technical language. English is not my mother tongue. Can you give me more detailed explanation of what you mean. Please do not use abbreviations, as they are difficult to find in a dictionary if they are listed at all. Why would Mike (creator of RCAP) put the C9 and C10 of the published value there, if they were not supposed to work? I suppose he must have had them checked working. Would you have any different suggestion? We are nearly through the Alt hold and Speed hold, working on RCAP to guide a model properly.
  9. Hi everyone. Has any of you flying experience with the RCAP as me? Do you have the Gain or Travel limit trims working? They are not working on my piece. I have tried Alt Hold of my construction. There are some problems but it looks it will work fine. I have bought and tested PicoPilot and returned it to the producer. I was not able to set it working. The support I got from the producer was nearly nothing. I would have to spend a lot of hours adjusting my plane and the control surfaces to start with it. Besides the software that enables the route planning was clumsy and not precise. RCA
  10. Hi I have sorely tested the RCAP in flight. These are the results. 1 The trims do not affect ether of the functions Gain or Travel limit. Solution to this is to reduce the rudder movement via the linkages. 2 Once it gets to the last waypoint, it starts holding there. As the intelligence of the RCAP relies on the GPS receiver, it would not hold in right or left patterns, but it would hold in random patterns. Typical example is: 3 right patterns, then two left ones then 1 right and so on. 3 The situation in number two can result in this: When the RCAP brings the model exactly above th
  11. Thanks to all joining This is my experience with it. First I have to say I work on it with a friend of mine who does the programming of the processor. I am the test pilot. He had to correct the program a little as there was no oscillation on the processor. It was an easy correction. We used the available files to program it from the net. It started to work afterwards. There is just a problem with the servo movement when it is not engaged. If the rudder stick on the transmitter is moved quickly, the servo gets confused. Example: I move the stick quickly to the right the servo would go there, a
