Futaba 7C problem

[George1234]

I have a problem with my 7C TX. It will arm 2 different ESC's (0 throttle) but every now and then, with throttle stick bottomed out, it will kick in a bit of throttle and spin the blades, or prop (low speed).
I have changed the TX anenna from a "rubber ducky" back to standard. Put in some negative trim and sub trim. This is with 2 ESC's, and 2 RX's. I'm running out of things to try!
Any ideas?????

Thanks in advance.

Looks like everyone is in the dark as much as me! I decided to have a look at it today, and found the throttle trim wasn't moving on the screen. I took the trim board out, and "exercised" the trim switches. After several attempts to get it back together with all trim buttons working, I finally succeeded, and now everything seems fine. For how long I don't know, but it seems to have been the root of the problem!

Corrosion? Is that your best guess so far? I'd expect that from mechanical trims but not digi trims. Maybe you need to maiden more helis to exercise your trims more often.

The digi trim buttons actually work seperate switches for each direction. I guess my throttle ones had a bit of oxidation, but they look sealed too much for a contact cleaner..................Want a heli maidened?

I'll let you know when I get another.

if it happens again, check into the ch3 epa. give + epa on the the throttle low point. at least that helped me, when my phoenix 60 spooled up on it's own. needless to say i almost soiled myself, as i've never had that happen up to that point.

Thanks, I'll try that if it happens again,but I know for a fact I had a problem with the trim. When I tried to adjust the trim, the indicater on the LCD screen wasn't moving.
