This was actually posted in another forum, but I thought it might make for interesting conversation over her, too.

I fly Mode 1 also. Horizon switch's the trims over so that you have analog on Throttle. One thing that the Zap has over the JR 10X is the kill switch on throttle. On the JR you have to use the trim at the low end to kill. A slight disdvantage for mode 1 flyers in partiular. Maybe we should change the focus of this thread from 1 of Futaba vs JR to 1 of is Mode 1 better than Mode2. I tried Mode 2 last year for the whole season and it was imposible for me so now I switched back to Mode1. For me it is the better way. 
OK ... I'll start the debate.
I learned to fly Mode 1 because my dad flew in the Reed radio days (actually before then ... have a newspaper clipping of him with a transmitter base sitting on the ground it was so huge).
Then I learned to fly full scale while I was not flying R/C. After getting used to having the ailerons/elevator on one hand, it is hard to get used to mode 1 again. When I restarted R/C I got RealFlight on Mode 2. This felt good. Then I converted the controller to Mode 1 for my dad, he could fly it, but it was still difficult for me.
In a general aviation plane with a yoke, you fly with your left hand for elevator/aileron with the throttle on the right hand. You don't fly with both hands on the yoke. I can fly this mode (is it 3 or 4?) better than I can fly mode 1. In a stick equiped plane, pitch/roll is in the your right hand, and throttle is in your left hand (mode 2).
I have found one major advantage to mode 1 since getting back into racing. When you fly a knife edge all the way around the course, mode 1 actually works pretty well, because you only have to change the orientation of the left stick for the majority of the control. IOW, aileron/roll stays on the right hand. I don't fly the high alpha stuff yet, but I can imagine that the rudder/pitch control on one hand and roll on the other could be quite useful.
