Hi Evadeom

Happy NY from Oz

Here down under most of our radio's are Mode 1 ie throtle/rudder right stick but because alot of hobby shops here bring in RTF planes from the USA and some can only be used in mode 2 and the problem comes when you move on to bigger and better planes and join clubs because they all fly in mode 1 (in Oz) and will train you in mode 1.

So back to your question if in the US if mode 2 is mostly used then set up the FMS as mode 2 and get practicing

Cheers Lawrence
