CeeGee. I agree with Rocketman. That is the best way to do the programming and that is how I did mine. I only use 7 channels, including battery, but one of them is in channel 8, and I selected the ailevator feature. However, you would be able to protgram channel 7 to do the same thing. The only difference is you'd have to do the programming instead of selecting a pre program feature. There is an excellent website for futaba (futaba.com, I think) and they address a lot of questions on the website on how to do this stuff. Also, they accept phone calls at no charge to help people with programming. I had to use them quite a bit when I was setting up my Ultra Stick 40 for flaps and also having the flaps act as ailerions. That took a lot of time but they finally got me through it and it worked perfectly. But I think your situation is much simpler and you can probably find the answer on their website. (Web site is: www.futaba-rc.com) Sorry I can't remember much more about the programming as what I do now that I have my planes setup in the radio is I just copy the closed programming to any new model and then just change one or two items and set up the trim. Hardly any programming to do anymore. Anyways, I think you can get this to work with the receiver you have now if you do the programming thing. Also, in the future purchase the 8 channel receivers. They are worth it. I use the PCM version because I like the fail safe features and the tighter tolerances. I think this helps with flutter also. You have twice the resolution with the PCM units as you do FM. Anyways, hope this helps a little bit.
Thanks,
