Futaba 7CAP Support
I'm nearly finished asseblying my GSP Cap232. I used 2 elevator servos. After an hour of fooling around with my radio (Futaba's 7CAP), and radio instruction manual, I was finally able to mix the two servos and elevator halfs sucessfully. However, when I adjust the elevator trim, only one servo moves.
Does Futaba have support on RCU like WildhareRC does? How do I get this problem solved? Thanks, Jim _____________________________________ Failure is the opportunity to begin again more intelligently. |

Yes they do, and between here or there hope you get your answer.

RE: Futaba 7CAP Support
Thanks for your help. I went to that site and posted the same question. However, I noticed there were other unanswered questions there. How often does Futaba check that site and follow up on problems/questions?

RE: Futaba 7CAP Support
The short answer to your question is, you cannot do it in the radio. The capability simply isn't there. You'll have to use a reversing Y-harness or other electronic aid to tie two servos into one channel. As you discovered, you CAN use a Pmix to make it happen, but then you have no trim on the slaved side.
If you'll look a few posts down from your original one in that forum, you'll see a fellow with the same question. He was asked about his set-up, etc., when a simple "no" would suffice. Perhaps "they" are reluctant to admit to any faults; dunno why that would be, because the 7C is a good radio otherwise. Why Futaba left out dual elevator servo capability on it is puzzling, but the fact remains. Bottom line is, you've got two choices; employ an auxillary device to gang your two elevator servos into Channel Two, or get another radio. The fellow mentioned above decided to upgrade to a 9C. Who won that one???;) |
RE: Futaba 7CAP Support
you got two options to do it right, the 7cap just doesn't do. I asked futaba about this a few months ago. their replied was this radio is an upgraded 6EXA not a downgraded 9C. so either
get a 9c radio or get a pair of hitec digital servos and a programmer and reverse one of the servos. you can do a y harness and reverse but the problem there is you'll have a hard time getting the servos to match. the movement and time will not line up |

Thanks Steve,
I'll have to order that Futaba SR-10 Dual Servo reverser from Tower Hobbies. I appreciate your input. |
RE: Futaba 7CAP Support
It is possible to reverse the servo internally, but it is not for the weak of heart or shakey-of-hand types.
Find someone in your club to do it for you or look for a ham radio operator to do this. There's lots of posts about this all over RCU. |

ORIGINAL: DrFrier Thanks Steve, I'll have to order that Futaba SR-10 Dual Servo reverser from Tower Hobbies. I appreciate your input. Actually, the more I think about it, the more I believe you should follow redfox's advice. If the elevator halves aren't perfectly in sync, the model will never fly right. |
