BOUGHT A XP7202 JR RADIO WE CAN'T ADJUST IT TO THE HELICOPTER IT JUST GO AROUND IN CIRCLES. WHAT AND BE DONE TO CORRECT THE PROBLEM IF ANYONE KNOWS THANKS DAN

Look for 3 servo setup in the menus. Have not worked with a 7202 but that is what you'll need to fly a Trex 450. It is a ccpm swash plate.

do you mean spin in circles on spool up? you need to be more specific but if its spinning in circles on spool up mine did this when I 1st set it up turns out gyro was reversed.

What gyro/servo combination do you have? Is the tail rotor servo reveresed?
Gary

YES IT DOES SPIN IN CIRCLES VERY FAST WHEN YOU GIVE IT MORE THROTLE .THE GYRO IS A JRG500T AND THE SERVO IS JR DS285. WHEN I SET IT ON THE FLOOR IN FRONT OF ME AND FACING ME AND TURN THE ROTOR BLADES CLOCKWISE THE TAIL BLADES TURN BACKWARDS WITHOUT THE RADIO EVEN BEING ON. IS THIS RIGHT ? IT WILL JUST SET THERE AND SPIN IN CIRCLES. HOW CAN I TELL IF IT IS REVERESED? I SURE THANK YOU GUYS FOR YOUR HELP

either reverse your rudder channel or the gyro itself......

Fwiw, you don't need to use capitalized block letters in your notes. It is considerd to be the same thing as yelling out loud in a quiet room.
Set the heli "nose forward" (tail towards you) and s-l-o-w-l-y advance the power/collective stick. Then let the thread know which way the heil's nose is starting to turn when power comes up.
