Just for the ease of set up you can use the HT 81s in each wing half to get rid of the torque rod set up. That always seems to be the stumbling block for most new builders to this little plane. Out of the servos you listed it's the only one I have used so I haven't got A clue about the others without looking them up. Getting an engine in that little cowl is another thrill if you want it to look good. I just rebuilt one for A friend this year and made some changes for him, really for myself, I like easy.
