Blogs i write are mostly related to OSRC in one way or another, may it be a user manual, tutorial or something interesting for the reader. Since i developed the OSRC system, naturally writing information about it is my main priority. However now and then i do tend to write my own thoughts about other topics, related to technology.

Dual Rates

If you need to adjust the Dual Rates on a channel then this section will guide you through the steps needed to achieve just that. Besides the commonly known functions, the OSRC firmware provides additional control over the setup to assist the operator.


Visually, the Dual Rates are controlled the same way as the Exponential Curves. The difference lies within the part of the curve being controlled. Just like the Exponential settings, OSRC uses the Gamma Correction formula to display the curve. The part of the curve that is controlled in this section is what can graphically be explained as the Tail of the curve. By altering the Minimum or Maximum values, the Vertical Scale (sort of speak) is altered.

Chan - Channel Number

This option lets the operator select which channel is to be modified. For practicality reasons the only channels that are affected by the curve are the first 4. Although we could easily make all channels be affected by curvature alterations, for the time being there seems to be no reason to do so since the values in most need of this feature are the ones controlled constantly by the operator, which are the 4 axises on both Control Sticks.

Min & Max

By selecting the appropriate option, the operator can control which part of the curve needs to be altered. As on most known devices, there is an option to control separately each side of the curve.

Zoom Function


If needed, the operator has the ability to Zoom into each section of the curve to make slight adjustments. By activating the Add function, the operator can Zoom In on the graph or Zoom Out by triggering the same function.

The part of the curve that shall be magnified is the one selected through the Min or Max options. So if the operator has the Minimum option selected, then by activating the Zoom feature, the Minimum part of the curve shall be magnified.


Have been working with electronics for as long as i can remember. Always enjoyed making something new and having the pleasure of seeing it work at the end. One of my latest and i must say, greatest creations is OSRC - Open Source Remote Control. Finally i can work on a single project, devote my full attention towards it and improve it as much as possible, with help from the RC and general Open Source community.
