But most important the bar that the lines attach can be removed allowing you to bring the handle back to the model to start the motor, run the throttle and maybe check to see if the other two channels are functioning. Then walk back to the handle slide the bar back into position and then fly the model. The last time something like this was available was the Bill Young handle that was a down the line electronic control system. With this being Spectrum 2.4 Ghz you can easily find a receiver and hook up any servo or ESC for electric power throttle control.

Carlos - Make additional bar units available so that people like myself that have a dedicated set of lines for a model can move the handle from airplane to airplane without unhooking the lines from the bar unit

Exactly Fred!
The idea of being able to separate the handle from the wires easily came from Bob, we just refined it and took it to the next level, not only to be able to disassemble the wires to start the engine but also to be able to interchange models easily and quickly.

My goal is to sell the rods with the screws and cable separately and also the receiver, this way you can have as many modes as you need and use the same handle (although for now you can only store the configurations of 4 models in memory).

Unfortunately the hardware we are using at least for the prototypes does not allow linking with any other receivers on the market so we have created our own receivers with up to 5 channels.

Carlos - Contact me with pricing and other details that I put into the Feb CL Scale column. I would need the information by early Nov to get it into the magazine

Don't know if you ever saw the Bill Young handle, he built a down the line electronic control CL handle similar to yours in the 1990's that Grant Heistand and I tested for him. He ended up selling his also, I don't know how many he sold but they were used by the CL community. I have been flying with converted 72 Mhz radios using the down the line methos since 93' and converted over to 2.4 Ghz in 2013. Not all but most pilots these days are flying with the 2.4 Ghz controls.

The attached picture shows three handles:

Upper Left - Bill Young single channel down the line handle
Upper right - Bill Young 3 channel down the line handle
Lower Left - Converted RC Car transmitter built into a handle

I donated these to the AMA Museum over 2 years ago but they have yet to put them on display in the museum

Yesterday was first flight of our LineMaster 2.4GHz. I think I speak for myself and our test pilots when I say that we had a great time.
In the video, you can see how we performed a flawless flight with no mishaps, testing the throttle control functionality. Alan Abriss officially became the first person to fly our LineMaster 2.4GHz.

It was also my first flight (the person with the black T-shirt) and it was an amazing experience to be able to master the model with some ease thanks to the speed regulation capabilities of our handle. This shows how intuitive and easy to use our product is, even for beginners.

Moreover, not only did I have fun, but also Alan Abriss and Russell Graves, two pilots with many years of experience in control line flying, showed the joy of someone discovering something new - seeing their smiles and enthusiasm while using the LineMaster and during the discussion afterwards was amazing!

And many thanks to Bob Whitney for his guidance and patience and for donating his old Ringmaster for us to use as a test platform.
