I am in the process of installing my JR XP7202 in my Shark 450 since I don't like the original radio that came with it, but on the original receiver is has channels marked and not ail., rud., and so forth so I am a little confused on which servo goes to which on my R790 rx. That and when I power it up my gyro wants to just blink red and beep, so I can't get my radio to scan for an open channel. Any help would be greatly appreciated. Oh and also not sure which way the plugs go into the receiver. thanks again for your time.

it should be listed in ur manual but i will list them for you =)
1- throttle
2- alerion (the helis left swash servo)
3- elevator
4- rudder ( gyro in)
5- gear
6- pitch ( helis right alerion)
7- gyro sense

Now u will have set ur radio to a 3 servo swash for it 2 mix the 2 alerions and if the rt servo is moving opposite then switch the 60 on servo on that page in the tx to -60 or vesi-versa to the left alerion. the gyro wont stay lit till it recieves a signal from the tx and it will blink till u set the gyro sense over 50% for head hold on the gy 401. i would start at 65% but make sure u set 0 deg on the tail in non hold mode first which would be any thin less then 50% so i set the switch 1st position to 65 then 2nd position to 40 so when powering up the rx leave it in 1st then switch to 2nd after the gyro init's then set 0 deg and ur done so no really sure how scan select works but read the book and it will really help u. Ps on helio freak there are tons of radio set up and gyro set up u tube vids. just watch the vid of the trex 450 and radio set up. it will walk u through step by step =)

Thank you very much JEEP, that helped alot. I also figured out why the rx wouldn't find a channel on the tx, I had the radio on the wrong mode. So I changed that and used your post as a reference and got it up and working. thanks again for your help.
