Stick Jammer makes a good point.

Throttle management should be part of a well rounded R/C pilot development.

I feel that in mode 1 the throttle and rudder being both over on the left thumb tend to get ignored.

A good practice is to do inside loops. Full power on the up-side of the loop. Then as you are cresting over, cut the throttle back 1/3 or so open, and hold this on the down side. Want to make the travel time on the up and down sides of the loop as close to the same as you can. Finally, on the pull out you can add throtle back.

Practice this and I guarantee (this guarantee + $1 will get you a cup of coffee, most places) you will be flying smooth, pretty loops.

Take care,
