I have the original looger from Eagle Tree. For a long time I wasn't able to run the program on my computer while it works fine on a friend's computer. The instructions are not the clearest thing either with steps missing. There is no mention of the compatibility problem in the instruction. There is not trouble shooting either.
Then a few months ago, I changed the mother board and CPU on my computer and the program works.

The connection on the module for the current mesurement or to connect it to the computer are not keyed. It means that you could connect it the wrong way easily. That's finally what happen and now the module is dead.

The instructions are not the clearest thing either with steps missing. I know that when I bought it there was not much info available on/thru the website. It maybe better now but I will wait for someone else to play with it before spending my money on this again.

It's too bad because it would be very usefull specially to practice precision flying. The live telemetry and the GPS option looks most interesting.
