I am using my second weatronic, one 72mhz and one 2.4 12-22.

My advice is to suck it up and travle with the laptop. It opens up the possibilities. I have an A10 with 10 channels and 14 servos and have plenty to spare...

I was just looking at all of the data from two flights yesterday and it is quite comforting to look and see what is happening on baord that plane regarding signal strength, frames, speed, battery info, current draw etc. Not necessary for all jets but in this big bird it is a relief not to be worried if my signal is ok etc. Plus I have an audible warning if anything starts to be a problem in the air.
yes, more work to setup but still not a bad value, service is fair, Gerhard does everythin ghe can although I think he is at the mercy of supply from Germany.

Good luck, if I can help please respond here so we can share with others.
