I know you're just getting started but I would say to buy a little better servo that would easily handle a 90 or 120 size plane. At some point you will probably want a 60 size, maybe a 90 size and you will look at that money spent on just getting by on a 40 size as thrown away.

At least that is how my growth in the hobby was.... I bought many things over and over as I went larger. Wish someone would have mentioned this to me.

Now about the radio..... jk


Good luck,
Steve
