Linemaster 2.4 ghz
« on: April 18, 2025, 04:20:17 PM »
I read with interest the post by Carlos Diaz re development of the Linemaster control line handle. I participated in the Ringmaster event and the Linemaster would have been an excellent tool to be used in they this an event.
As such, I wonder if this handle is a available for purchase.

Hello Herb!
I am still developing LineMaster 2.4GHz, i am in the final stages so you may want to take a look at our facebook profile https://www.facebook.com/profile.php?id=61560480371015.
I also started a web site where you can find more info and FAQs. here is the link https://linemasters-organization.gitbook.io/linemaster-2.4ghz

best regards,
Carlos Diaz

Herb, could you design a simple light handle with just ON/OFF to allow 2.4Hz throttle shut down on demand for Stunt use? The current rules only allow 2.4Hz systems, having the ability to shut down on demand would allow for greater safety should some of us older flyers fine the need to end a flight or if there is any situation that could require ending the flight before the tank runs out. Ideally, having an idle start position that could go to full throttle then shut down would be great.

Best,   DennisT

I sent you the prototype of my timer, which also works with a remote control or Timer, albeit at 433MHz, and does exactly what you want.

You can test it, and your feedback will help us improve the device. There are already some minor improvements in the code done.

Both the FAI and the AMA prohibit remote engine starting and stopping via an RF device in F2B aerobatics and other F2A Speed, F2C Team Race, and F2D Combat, even if it's 2.4MHz, except for scale, which has separate regulations for only secondary functions.

Changing the frequency from 433mhz to 2.4GHz only requires a change to the timer's board layout, which is already designed, although no prototype has been assembled only in breadboard.

The RF key coding system has millions of possible combinations and it is the same as automatic garage doors. Changing the frequency to 2.4GHz will not make the timer legal for official competitions.
