Question Regarding Use of Minim OSD 1.1

Hey Reto,

Thanks for the response... I was confused (been known to happen on occasion), but I'm not using my AR7100, but I am using my Spektrum AR7000.   

Still having the same issue, no response in the Tx / Rx Calibration page in the Mission Planner.

I have moved this discussion to the discussion boards, and can be found HERE

Thanks,

Xomby

Hi Thomas,

The process to build a hex is almost identical to the quad (just add 2 more legs), so it should be quite straight forward.  However, the recommendation to start your own discussion is a good one and then we can answer your specific questions.

Cheers,
David.

Hi Thomas.

Here's the info about the ports you should use for your gimbal and how to configure it in the Mission Planner.

Perhaps it would be better if you started a new discussion within this forum specific to your issue. It'll be more organized, searcheable and easier to answer your questions.

Best regards.

Hi

Camera%20Gimble%20Port.jpg

I have atatched a picture of the port I am using for my camera gimble, can anyobne tell me if it is in the correct port. I am using the 2.5apm board

Many Thanks

Hi,

With the new 3DR Hexa Copter and the 2.5 APM Board, is there any instructions specific to this model? The site seems to have very little on the IMG_1186.jpg as far as pictures and diagrams are concerned. The site seems to only have Arducopter and it is very confusing when you purchased a 3DR Hexa Copter.

I think a picture diagram or a utube video from DIY drones would be appropriate on how to build and calibrate the Hexa from start to finish.

Like with any new product you get instructions from start to finish.

Hopefully this will happen soon.

Kind Regards

Thomas Mc Grory

@Xomby: manual of your Rx p. 6 states following. Could it be the cause of your problem?
"Because of the built-in regulator the AR7100/AR7100R has a minimum recommended operational battery voltage of 5.5 volts and is designed to use 6-volt 5-cell NiMH, 7.2-volts 6-cell NiMH or 7.4-volt 2-cell LiPo batteries. (Higher voltage should be used only if the servos are compatible.) While the AR7100 will continue to operate down to 3.5 volts, the AR7100/ AR7100R features a built-in 5.2-volt regulator for the Rudder, Aux 2, Gear 2, Throttle 2 channels output. A 4-cell 4.8-volt battery will not provide sufficient headroom (voltage margin) to maintain a 5.2 regulated voltage. Regulated outputs are provided to allow the gyro, gyro gain and throttle to be operated at the necessary lower voltage while the cyclic servos (aileron, elevator and pitch) are powered directly by the pack voltage (typically 5-cell 6-volt NiMH or if high voltage compatible servos are used 2-cell 7.4-volt LiPo batteries)."

Xonby: Use the Power Module with your LiPo. It's the best way to power the board. 

Comment by Xomby on February 7, 2013 at 3:50pm

Hey Chris,

Yes, I see I confused things a bit.   I was just TRYING to do the setup calibration with my Rx battery connected, because it was not working with only USB connected.  I do not plan to have an Rx battery once this thing is flying.   I think I read some post that said possibly the receiver may not have enough consistent power through the Arducopter only.

I'm at the very initial stages of configuration and have not yet connected my LiPo's or anything.   I did get the Power Module with my kit and will be using that.

So, should I try this initial calibration using my LiPo battery?

Hope this helps,

Xomby

Xomby: I'm a little confused by your power setup. What do mean by "Rx battery"? Typically copters don't have that. Also, are you using the APM Power Module? If not the little JP1 jumper that came with APM should be on. 

Comment by Xomby on February 7, 2013 at 1:44pm

Hey Chris and Group,

I am having a similar problem as Thomas Mc Grory.  The only difference is I got the Hexa-B kit, have assembled everything according to the manual.  I am at the "setup" step where I am to calibrate my tx/rx channels.

I have a JR 9303 2.4 radio system and am using a Spektrum 7100 receiver (JR and Spektrum are interchangeable as most know).

When my receiver is connected to the Arducopter, it just doesn't react at all.   I have tried when only connected to the USB power from the computer.   I have also tried with my Rx battery connected directly to my receiver (power from the Arducopter is also connected).    

The receiver light will not come on when connected with EITHER power scenario.

I saw a guy on YouTube that had the same problem, but he says he just changed wires from the 5 way connector wire designed for the Arducopter to Receiver connections.  Oh, I have put tone to the 5 way connector wires mentioned above, everything appears to be solid there.

Any advice?

Thanks,

Xomby
