hi guys i have a problem with my radio and hope some of you can help me to fix it; ive recently flew my US 60 (flies great) at the time of triming the plane found out that when ever flip the dr on my trim changes;
taking the time to find out what hapen i could not set the dr correctly but cant fix it
my set up as follows:

i did set the ATV at 110 (both ail and flap) (flaperon activated every thing at 100%)
the AFRset at 95(expo -20)
the dr at 78(expos -18)

is there some thing wrong with the programing or is it normal that trim changes when you flip of the dr

thanks in advanced

PS Im not willing to change Radio Brand!![:-]
