T1000FC Manual Mode with GPS


I've decided to open a new thread discussing the T1000FC and the Manual Mode
Bypass circuit (MMB) for the T1000FC Auto Pilot sold at Hobby King since the
thread where we were conversing was suddenly closed for some unknown reason
by the thread starter it seems.

For previous T1000FC and MMB info the thread in question is here...
https://www.rcgroups.com/forums/show...c#post29577313

There is another thread where some other solutions were also discussed
by jj604...
https://www.rcgroups.com/forums/show...closed&page=13

A few test samples of the MMB PCB have been sent out to selected members
that will put the circuit through the wringer and report back here.

This MMB circuit allows you to choose the middle position of a TX 3 position
switch that controls the flight modes of the T1000FC with GPS to get a Manual
Mode direct from the RX. This should now give you Stability Mode, Manual Mode
and RTH Mode. The original T1000FC middle switch position modes are no longer
available with the MMB.

I also posted some T1000FC GPS info on the other thread just before ir was
closed. Worth taking a look.

----Updated Mar 22 2015----------------

Here are links to purchase the MMB....

I also put them up on eBay for non-forum members here...

I am looking forward to this feaure. I put the T1000FC in two of my airplanes. The Skymule and the Twinstar-II. As much as I enjoyed teaching students how to fly with an auto-leveling system, it always felt like I had "dumbed down" the aircraft.


It is a super safety feature to have any aircraft with RTH (Fixed or rotary wings), but the price with the T1000FC was a complete loss of any aerobatics. I could not do a roll or a loop with the GPS turned on. Plus the control stick/flight response differences between GPS-on and GPS-off in self-leveling and non-self-leveling behaviour could only be taught by using different airplanes. (Or by rewiring).

I agree with you 100% Eric. That's why I decided to tackle a way of introducing
a simple Manual Mode with the T1000FC with GPS connected without requiring an
additional RX channel. The MMB uses the same 3 position switch RX channel
that connects to the FC Auto Pilot input connector.

The TC1000FC with the GPS connected has no modes that control the Rudder
so I connect the RX directly to the Rudder Servo like the Throttle.

I receive some feedback from one if the testers that the instruction drawing was a
bit unclear (the drawing in the 1st post).

I'll try to explain the functions of the individual pins of the individual rows in detail.
First so that we all talk about the same pins and row locations the vertical rows will
be numbered from left to right from one (1) to seven (7) and the pins per row will be
numbered from top to bottom as ten (10 Top) twenty (20 Middle) and thirty
(30 Bottom).

All rows from 1 to 7 have their 30 pins tied to ground that comes in from the
RX AUX output.

Rows 4,5,6 and 7 have their 20 pins tied to +5V that comes from the RX AUX
output.

Row #1 Pin 10 - comes from the RX Aileron Signal Output pin
Row #1 Pin 20 - comes from the RX Elevator Signal Output pin
Row #1 Pin 30 - is Ground

Row #2 Pin 10 - goes to the T1000FC Aileron Signal Input pin
Row #2 Pin 20 - goes to the T1000FC Elevator Signal Input pin
Row #2 Pin 30 - is Ground

Row #3 Pin 10 - comes from the T1000FC Aileron Signal Output pin
Row #3 Pin 20 - comes from the T1000FC Elevator Signal Output pin
Row #3 Pin 30 - is Ground

Row #4 Pin 10 - goes to the Aileron Servo Signal pin
Row #4 Pin 20 - is 5Volts
Row #4 Pin 30 - is Ground

Row #5 Pin 10 - goes to the Elevator Servo Signal pin
Row #5 Pin 20 - is 5Volts
Row #5 Pin 30 - is Ground

Row #6 Pin 10 - goes to the T1000FC Auto Pilot Signal pin
Row #6 Pin 20 - is 5Volts
Row #6 Pin 30 - is Ground

Row #7 Pin 10 - comes from the RX Aux Signal pin
Row #7 Pin 20 - is 5Volts (supplied by the RX)
Row #7 Pin 30 - is Ground (supplied by the RX)

BTW the first three rows #1, #2, #3 have special servo leads
that are supplied and look like the the pic below. The Connector
on the left with the 3 wires plugs into the MMB PCB.

Rows #4 and #5 use the lead attached to the Ail and Ele Servo.
Rows #6 and #7 use standard Male to Male Servo extensions.

If it still seems not clear just let me know.

T1000fc


I have been one of the lucky ones to get a prototype version of Lasersbee's MMB switch and have been testing it for him. I am glad to tell you that it works flawlessly and is easy to setup . This little unit gives you your plane back! The centre TX switch position now turns off all Stabilization. The positions either side of centre are Stabilized mode and Return to Home, just like it should be from the manufacturer. Great work Lasersbee.

Thanks for doing the flight tests 747guy. Glad to hear the MMB circuit does what it
was designed to do.
Just waiting for the other testers to chime in. I know some of them are having time
and/or weather issues/delays.

Subscribed. I'm putting the gear into a plane finally to test this weekend.

Lotsa stuff
747Guy, Thanks for the reply on the HK discussion. As you can see, I've found it.

great news


Hi, I commented on this on the HK site and a few of you were very helpful to tell me about this thread!
I'm in England, how can I get one of these boards to add to the TF1000?

I'm keen to add RTH to my sky cruise 2400 before attempting anything beyond los and even in that monster I still do loops and rolls!

I'm just waiting for a few other testers (to confirm or not ) the findings of 747guy
before releasing the MMB for sale. I Just want to be as close as possible to 100%
sure that all is fine.

Well the wind was finally down enough and In found the time today to test fly
my Sky Surfer fitted with the T1000FC and MMB. My mechanical servo setup
required two servo reversers between the RX Aileron and Elevator and MMB.

I took off in stability mode as I usually did and once in the air and about 400
feet away I tested the RTH and all was as expected. This time I remembered
to set the Home position before taking off.

I then switch to Manual mode ready for any weird characteristics and... Whew...
It worked like a charm. For a Manual Mode test I looped the plane.... Inverted it
and rolled it with no adverse effects.
I then put it in stability mode and landed as smooth as possible.

I must add that since I designed this MMB I may be a bit biased. But I really like
this Manual Mode add on to the T1000FC.

Just to say I finally got a chance to try mine in flight today.

As the English would say, "It does exactly what it says on the tin."

Well, done, Jerry.

I put mine in a stock EasyStarII as it was a windy day and it's a good test of stabilisation for a lightly loaded underpowered foamy.

What was different is that I did not use a straight receiver but a Lemon DSMX 7-channel stabiliser which is a 6 channel DSMX receiver integrated with an excellent 3 axis rate stabiliser.

So with my DX8 I had Lemon Off/Stabilisation on the Gear switch and T1000 Autopilot/Off/RTH on the Flap (Aux1 switch) switch. I did not need any servo reversers. I just soldered the headers into the board, plugged it in and it worked with the leads supplied. I set the rates on the Lemon with the T1000 Off, and vice versa.

So I ended up with 4 switchable options:

1) No stabilisation (Both switches off)
2) Rate stabilisation with in-flight gain control (Gear on/Flaps off - position 1)

And with the Gear switch off and the Flap switch at position 0 or2
3) Autopilot (self levelling)
4) Return to Home

It all worked perfectly.

You would never turn both stabs on in practice but just for fun I turned both the Lemon stabilisation and the T1000 Autopilot on at the same time. As expected, after a bit they got into an argument and started to fight one another and the plane began to oscillate with increasing frequency.

This is a much neater solution than my buddy box switch. I think I will remove the headers and permanently wire the two stabs together to make one neat self-contained unit.

I'm just waiting for one last Tester's results. I'll work on the pricing and put
them up on eBay to sell.
I think I'm going to put a Special discounted price sale in the RCG classified
section just for the members here that buy directly from me. You will just need
to give me you RCG user name and contact me through our website.

Thanks for the kudos guys...
Thanks for doing this testing for me John and all testers. Nice detailed explanation
of your tests. I just love data...

That is now 90% confirmed as a viable Manual Mode Bypass for the t1000FC
Auto Pilot with GPS..(in my mind).

As I stated above I'll make these available in a few days.

Jerry
