Setting up the Futaba T8FGS (or 14SG) with the P2

Re: Setting up the Futaba T8FGS with the P2

Ian,

Yes, I was able to install your v4 model for the T8FGS on the 14SGH. The docs for the 14SGH specifically talk about that upward (but not backward) compatibility.

Thanks for the insight on the double flashing green tail lights. I haven't solved the left stick centering issue, so either that or the yaw knob are almost certainly the source of the double flashing. Good to know.

Someone asked about tethered flying. Pretty low tech: tie some parachute cord to one leg of the phantom, and the other end to my kid's tractor. Enough rope to confirm what bench test suggested without props: all control inputs working well, and no flight risk with the new radio.

Like I said this morning, can't wait for real flying with the yaw knob, de-tuned inputs, and smooth tilt.

Re: Setting up the Futaba T8FGS with the P2

When you bring the throttle stick below 50% there should be a gradual decrease in motor speed to decent and land. I am correct in thinking that? If so then with I bench test no props I should hear that and I don't. Neither do I hear a slowing of motors when going through the triple rate. Just need a little help understanding this.

Running the motors on the bench without props is not a good way to judge throttle response. The P2 is not calibrated to run WITHOUT props installed (no load). Triple rates are not set up on the throttle by design. Just the yaw, aileron and pitch channels.

I've updated the first post in this thread for information on adding a flat spot to the throttle curve and more detail about the calibration process.

Kelly, if you make sure you're fully calibrated and you are careful with the position of the switches and dials at take off, you shouldn't need a tether. If it makes your more comfortable, some fishing line will probably work. Give yourself about 15 - 20ft.

Here is one of mine. http://vimeo.com/86677054

I love the way you captured the frost/snow on the trees with the slow movement even into the forest. It set a mood that I'm sure you were shooting for. Very nice video.

Motors running on the bench don't sound like they should

Yep. The props make a difference, if GPS is on that will make a difference (you just confused the crap out of NAZA since it can't move and therefore inputs all seem to be failing). Checking to make sure it will start and that the motors are turning the right way are about the only reliable tests for bench work (basic tests) on the motors themselves. Once the basics are there, take it out and fly it.

Wanted to report back that I had my first short flight today with the T8 tested contin yaw, stick control, camera range of motion, but forgot to test fail safe. I will in a few days. Thanks to everyone for all help!

The thing is... I'd much rather be able to go around buildings and structures then go long distances without loosing video link. Is there any way to do that!?

5.8mHz is terrible for that. If you move to 1280mHz, you get better reception behind things.

One thing that link didn't mention is that you might need to put filters on the system to prevent harmonics from interfering with the 2.4 channel (*your control channel*). The antennas will be bigger, too. However, if you get past all that, the penetration of 1.2 is much better than 5.8 (by far).

Hi all,

I've been reading this thread for the last few weeks and as a result I picked up a T14SG. I installed BrandonBallad's profile and all was well the P2 worked and flew fine.
Yesterday, wkf94025 installed ianwood's v4 model for the T8FGS on the T14SGH.

Today I installed ianwood's V4 on my T14SG without modifying any parameters, connected to Phantom 2 Assistant Software, did all verifications and calibrations, all functions work with bench tests. However, I am not able to start.

I (believe) insured that all switches are in there correct position for start-up. I checked that the LD yaw pot is centered.
I still cannot start.

I should point out that If I select BrandonBallad's T14SC profile on the radio, all is well, P2 starts with no issues.

I'm stumped...... I not sure what I am missing. Any suggestions????????


@wkf94025 Did you change/edit any of ianwood's parameters to get you radio to work????

thank to all

tonben

 

[ianwood]

Tonben,

Did you re-calibrate the controls in the Phantom Assistant? Just a guess, but you probably need to do that as the end points may be different to Brandon's.

Now if only Futaba would send me a 14SG so I could test my profiles on it for all the people on this forum who are buying Futaba radios!!! Ehem, yeah.

 

[wkf94025]

Tonben,

I did not edit Ianwoods's model at all. I had one won1t-start moment that I realized was due to triple rate switch not being in full north position (100% rate). Did you calibrate sticks with that switch full north?

[tonben]

Thank you for the reply ianwood.

I did recalibrate all controls and insured that all values were correct in Assistant software. I was even able to see the value changes with the LD pot yaw option. Additionally all your programed Gimbal functions work perfectly.

That is the puzzling point. Everything works on the bench with the exception of a start-up.

I'm not 100% sure I had the triple rate switch correctly set prior to calibration.

I'm at the station now. i won't get home before 1amEST. I will absolutely check then.

From all indications that should be it.......

Thanks Kelly

I think I had mine set wrong (or something) moved it to center and the thing started. It will be some silly thing like that.

I'm FIRST in line to subsidize your 14SG radio purchase!!!!

$20/25 from all who benefited should do it..

Any others???????????

Good point. I forgot to mention this in the instructions. Make sure all switches are in the back-most position (except for SB which should be in the middle position) and LD is centered when calibrating. This is now in the instructions in the first post.

 

[extrememc]

See ianwood I told you. I am in!

Should I have it in the center? If so, it definitely was not centered when I tried to start.

Something to check when I get home.

thank you ever so much........

He's talking about the switch that controls the gimbal slow tilt (SB), not the triple rate switch. The SB switch is the only one that needs to be in the center when calibrating.
