Here is a fun game to play you can all try out.

You must do this solo with no help from anyone else or it does not count.

Get yourself setup for an AP flight by doing the following.

1) Setup your heli with camera and mount on the ground ready for takeoff, but no batteries plugged in yet.
2) Setup your tripod with lcd display and downlink about 3-5 feet from your heli.
3) Under the tripod set 2 extra sets of battery packs, one spare camera, one camera bag, one blade holder, and 1 Tx. ( Make sure your Tx is a high end one that is synthesized and costs about $400-$500 or more.)
4) Stand about 3 feet back from the tripod and pretend your waiting for the right time to go airborne to get the picture. ( Good photographers are patient right??)
5) Oh yeah, almost forgot, carry all this crap about 3-400 yards from the car by yourself when it is 85 degrees out, and about 2000 % humidity, and make sure the place you're carrying it to is overdue for a grass cutting so the mosquitos are really bad.

Now have the automatic sprinklers in the field you are on pop up instantly and be pointing about 2 feet away from your tripod and everything under it, and have the sprinklers start moving toward your tripod, and have them continuing on towards your heli next (remember your camera mount and camera are under the heli, and just for fun, make sure it's an electric heli with a nice big expensive HV ESC on the side that would first get hit with water.)

Ready, GO!!!! Pick up everything as fast as you can and see if you can do it without any of it getting hit by the sprinklers.

OK, how'd you do?

Anyhow, that was my evening today. I actually managed to get it all up and out of the way of the sprinklers.

The shoot went well. I shoot football stadiums for an artificial turf client of mine. They have been telling me the schools have been asking if I can come shoot their home openers with the crowds in the stands and the stadium lights on. I did not think there was enough light at kickoff to do it, but have had enough requests that I went out for a test shoot tonight.

For the safety concerned. This was from a practice field that butts up against the fenced in main field and I was at the far end of the football field on the practice field. I was at least 150 yards from the fenced in
main field. I went up about 100 feet took some shots and came down. 2 minutes in the air. It was all cleared with the AD and the school.

My wife was sports shooting the football game. She had field access and was at the far end of the football field in the endzone, she took a few shots for me. She had to be pushing 300yards away when she took the shots.

Hey who's the creepy guy watching the game all by himself?

Oh yeah, I forgot one more thing to make the game even funner. After it is all done and you land, be real anxious to see the pictures. Don't wait till you get back to the car. Take the camera off the mount, and look at the images. Then put the camera in its bag, and put it your already overstuffed shorts pocket. (remember spare batteries and stuff are already in there.) Carry all this stuff 300 yards back to the car, you're dying now remeber 2000% humidty and 85 out. Put all the crap in the car and want to look at the picts again in the air conditioned car. Hey, wait a minute, where is the camera that took all the pictures from this shoot???? :shock:

Run as fast as you can back to the shoot site, retracing your steps looking for your camera. Get to the shoot site and find your camera in its bag laying in the field and guess what's headed for it? Yup, the sprinklers have now moved over to their next zone, heading for your camera. I got it before it got wet. :D

Get back to the car and take about 4 bazzillion napkins you have and try and wipe some of that sweat off your face so it quites rolling into your eyes and burning them. Go drive the car around to the normal parking lot, head down onto the field and meet up with your wife who's shooting the game.

OK, who wants to play???? :lol: :lol: :lol:

Funny, I did a shoot on Monday clear across the state, and drove 450 miles that day and everything was flawless. This shoot was 10 miles up the road, and all heck broke loose.

And don't forget now kids, when you talk to the AD and ask him if it's OK to fly from that practice field, ask him if there are any sprinklers in it and what time they will be going off!!!

Interesting game, but...I think I'll pass. Good tip though. I guess, from the overhead shots, you'd want to be standing in the dead grass areas to be safe, huh.

Nice shots, too!

Great story, Scott!! Sounds like a fun time! :lol: Well... in the end you did get the shot(s). That's what makes a pro! :mrgreen:

Sounds like AP is the career for me! :D:D:D

Do I qualify for the reserve team? Friday I got a 2S 300mAh LiPo for my AP camera and downlink, and set it all up for testing.... and then went out for 4 hours leaving it powering the downlink camera! Luckily the drain was less than 100mA, so it didn't puff or burn the house down, but it only had 3.15v in it when I got home!

I hooked it up to my Tx charger at 60mA and watched it like a hawk until voltage read just on 7v, and my LiPo charger then brought it back to life again. D'OH!

Thanks Mark, yes, the overhead shots and dead zones are obvious now that you have the aerial view. They meant nothing to me when I first walked out there.

But those ended up being the takeoff and landing zones.

Definately, you're in dude. :D Been there done that with a 2s 1200 that powers my hole camera mount with downlink and all.

My TP1010 charger would not touch the battery and kept erroring out, even at 100ma. I had my old triton charger and was able to revive it enough to put it back on the TP 1010 and it has been fine.

Very good tip about the Tx charger, as that will always be with me in my Tx case.

I was holding onto the triton incase this happened again, now I can go sell it. :mrgreen:

I like this game! sounds awfully alot like a game I once played.

1. bring two Voyager E helicopters to the field. One is in a scale A-Star fuse the other bone stock.

2. set up one Voyager so that the esc/throttle channel is reverse of the other

3. fly the scale one as soon as you arrive. put in a good 5 minute flight. feel accomplished after landing.

4. forget to disconnect the battery in the one yuo just flew

5. pull out the other Voyager, plug it in.

6. with both models plugged into their batteries change the model setting on your transmitter.

7. as soon as you hit enter and switch to the new model, observe the scale Voyager spool up at an insane rate.

8. realize that you need to advance the throttle to get it to stop spinning (because of the reversed throttle) and advance the throttle to full to stop the scale Voyager.

9. forget the fact that the stock voyager is still plugged in and now watch it start to spool up.

10. see both helicopters begin to take flight at the same time.

11. pick one to fly... the easiest one without the reversed throttle. chop the throttle and let the scale Voyager roll over and eat dirt.

12. (this is the best step!) DO NOT REALIZE UNTIL AFTER ALL OF THESE STEPS that all you needed to do was hit throttle hold (works regardless fo throttle sense)

yes I played that game once.

Yikes! Why is it that the brutally obvious solution escapes one is such circumstances? I hate when that happens!

Are you sure that would have been the effect ? Throttle hold merely brings the throttle channel to a preset position regardless of stick movement. That position would have been low throttle on one of your helis, and high throttle on the other ?

come to think of it I do believe you are right.... hmmmmm.... I was damned either way. wow... all these years I thought I was so stupid by not hitting throttle hold.

hmmm what is more stupid, not hitting throttle hold or not realizing that it would have made no difference. that damn crash has come back to stab me even years after it's occurence.

Man DJ, picturing that now, it almost sounds comical to have been able to have seen it.

I'd have been crapping my pants at the time, but another good story!!

DJ - one way you COULD have got around it is to hit hold and full positive pitch (stick up) and the one with the correct setup would just hopefully spool down, while the other one would be at negative pitch and hopefully now coming to a stop. We can't let you off THAT easy for making a mistake.. :D

Not the case with Futaba. Not sure about JR....

In all that making new models and stuff to get my AP2000i right, I went to the field with my RaptorCam with the throttle in normal instead of REV and as soon as I plugged in the packs, the thing armed and started spooling up. I immediately hit hold...nothing. Then luckily for a slow softstart, I was able to go into the menus and reverse the throttle channel then hit hold and it worked.

Could have been a lot worse!! :shock:

That is crazy with a possible 2 crashed at one time. :arggg:

I think the only real solution (if you programmed failsafe) would have been to turn the Tx off. This would take some really quick thinking though in a crazy situation.


That is a wild story DJ, I cant imagine trying to fly 2 at once! :D

Failsafe is the result of sending information on what to do if the signal is lost.

If he shut off the TX, and had failsafe to 0 throttle, then one heli would have shut down as expected, and the other would've attempted to achieve orbit as, due to being reversed, failsafe sent it to full power.

NO way. I'm with Tabb on this one. Failsafe is in the Rx. 0 output from the Rx to the throttle would be the same for both Rx's no matter if they are reversed or not.

The reversing was done in the Tx right?

When you shut the Tx off, the Rx knows nothing about the setup of the Tx anymore, and the failsafe will take effect with what is in the Rx which would be 0 for both heli's and they should both shutdown.

DJ said one Voyager (read: heli / rx, not transmitter) had the ESC channel set up as the reverse of the other.

Therefore, on one heli, a pulsewidth of 2.0ms = 0 throttle and on the other one, 1.0ms = 0 throttle.

The TX sends the failsafe info to the receiver through the datastream (at least on my 9chps. I don't know how the 14mz or JR or any other radio does it...)

Thus the failsafe programming on the receiver is going to be updated within a few seconds.

Further thus, if the signal is lost, both receivers are going to fail to (for example) a 1.0ms pulsewidth. On one heli, that's going to be 0 throttle. On the other, it's 100%.

Teej

I don't know what system DJ was flying.

Whether shutting off the TX would've been good or bad is dependent on luck, timing and the specific system in question.

In the case of my gear (9CHPS) the failsafe data is updated every 2 minutes. It sounds like he had both receivers on for at least some amount of time (long enough to hook up the motor batteries at least). Murphy's law says there would've been a failsafe update packet sent in that timeframe, thus making one of the helis "faildeadly" instead of failsafe.

08-28-2006, 07:11 PM
That's a good question/point guys... how DOES failsafe work? Is it reporting the correct setting for what fail safe is every so often, or once? And if so is the receiver storing this data to some sort of flash memory that it forgets after being shut down (or PROM instead)? Is the receiver waiting for this "packet data" all the time, or only within certian time frames? JR vs. Futaba?

Teej
08-28-2006, 07:16 PM
Read your manual to be sure. I know for fact the 9C-S works the way I said.


Updating F/S Settings: If you specify a F/S setting, the FailSafe data is automatically transmitted once each two minutes.
When you choose the F/S mode, check that your settings are as desired by turning off the transmitter power switch and
verifying that the servos move to the settings that you chose. Be sure to wait at least two minutes after changing the setting
and turning on the receiver power before turning off the transmitter to confirm your changes have been transmitted.

In other words, Make changes on TX, leave TX and RX on for at least 2 minutes to be positive the update is sent, then turn off TX to confirm movement the way you intended.

But somebody needs to tell the creepy guy watching the football game to put on his long pants...... Makes the mosquitoes a whole lot more tolerable....

Thanks TC, did you not see the part about it already being a million degrees and 2000% humidity? :mrgreen:

I'll take the heat and humidity ANY day... as long as I don't have to put up with mosquito bites....

I hate those (*&$#%&)!# little bastards! For the first time in 30 years, we actually had a few of them here in New Mexico..... but they died off in a couple of days. We've had 8 inches of rain here, so far this summer... Unheard of!
