Data Flight Log
 

Hi guys, another rookie question. Starting to set up the electronics on my Jetmach 60. Can a data flight log be permanently plugged into say, a JR 1221 receiver and viewed after a flight or must the data log be plugged into the receiver after every flight in order to check holds, etc. ? Thanks. Chic

On my planes w/o telemetry, I leave the Flight Data Log reader in for the first few flights to gauge how far out I can fly the thing. (e.g. I see a couple Frame Losses and I know I was near the edge of the transmitter's coverage area.) Every time the Rxer is powered off and back on, the data resets. Once I know how far out the plane is safe to fly, then I just put in the logger when a problem is IDed or suspected. To keep things as simple as possible, until a plane has several flights on it, I like to use the flight log reader. Then, after several flights, I put in telemetry.

On my planes with telemetry, the data is logged in the Txer. The Flight Log Data reads out on the Txer's screen. I get an alarm on a Frame Loss, etc.. I also have telemetry on my gas plane's RPM, Head Temps and Battery Voltage which reads out on the Txer. I put alarm set-points in for each parameter. In-flight RPM data is great for testing various props to get the engine in its powerband. In-flight head temps are great for testing different baffling arrangements to get the best cooling, etc. I love real-time telemetry. But, until the plane has a few close in flights under the belt, I avoid it just to keep things as simple as possible.

Thank you Len Todd so much for your response and explaining how you use the data log. Chic

you can put the TM1000 and the data logger reader on a Y cord and leave em both in the jet if you want.. both will work at the same time, giving you the option of telemetry and a quick check in the jet. either or...

I used to put both in since they are cheap

I have a data logger in each of my planes and my boys planes other than the foam park flyers. Its not an insurance policy that something won't go wrong but it is nice to see if things are not working up to spec or normal like on previous flights, before the next one. I also still use my GSU on my turbines as well, again l like to see good numbers before I taxi out. Not any different than a full scale pilot scanning the cockpit before each and every takeoff just to make sure the gauges look good.
