Hi, welcome to the forum.
What kind of rf remote do you want to clone.
If it's one with rolling code (cars, gareage doors, etc.), forget about it.

Leo..

it belongs to a model aircraft it is part of a system made by a guy in Russia i have no idea if its using rolling code... in fact i know verry little about it. only that it is doing a very a basic function and they are charging us way too much for it. (around 190 euro) so i want to make my own
