They are not crash proof, but of all RC flying, they are the easiest. That being said I've tipped it over twice knocking 2 props into the ground and managed to crash it into a tree once. No damage I can detect, but that's over about 100 flights. If you're interested, I'd get a toy one first and master that (Hubsan makes a good one for about $50) before you move on to something like the DJI Phantom. 

 

I have the Original Phantom I paid $429 for delivered when they were on sale at B&H camera. The stock battery gets about 9 minutes, and the larger 2700mA battery gets about 12 minutes.

 

They're supposedly elevation limited within 5 miles of major airports and a mile of smaller. I'm not aware of a legal ceiling, but FAA recommends keeping them under 400' which is where I fly mine 98% of the time. Only on two occasions have I brought it up over 1500' and that was just to see how high I could get it before I lost it. Like I said, it uses GPS and will bring itself back to home as long as it gets a GPS lock (takes about 30-45 seconds) at takeoff.

Does it have like a reserve battery or something that would get it to the ground if the battery runs out up high?  Like say f you're 1,200ft up and run out of battery, does the thing just fall to the ground? 

 

Do you bring multiple batteries with you so you can play around for like a half hour of flying?

With the Phantom2 and the GoPro active with the H32D gimbal (which keeps cam level) you can get 18-20min flight time. Without the camera, 25 is possible.

 

It starts blinking red when the battery is reaching critical levels, I've always brought it down once it starts doing that. It's suppose to have a failsafe and "return to home" feature that it will trigger. I say suppose to because I haven't had it happen yet. I've flown it probably 30+ times, and I'm only guessing but I've had it in the range of 1500+ feet away and up with no loss of control. The GPS keeps it really stable, as in you can let go of the controls and do something else and it will hover there. At first I was scared of wind, but this thing does well even with a light-moderate wind.

 

My one issue was I totally forgot it also relies on a compass for direction and I tried to launch it from a railroad track. Lets just say it flew in an immediate fast arc and crashed into the woods. Broke a prop on that. Screw a replacement on and you're good to go again (it comes with 4). It's amazing technology, the stuff we dreamed of as kids.

 

Note - if you want the FPV (live video) look for the first person view when buying. That has a separate video transmitter that can then beam directly via an APP to your smartphone. Technically you could do it by turning on the GoPro app and using its' embedded transmitter but they don't recommend that because they both run on 2.4GHz. Any questions I'll be glad to help.

Typhoon Tip, and other folks on this forum,  do you folks see the back door days of Tuesday 6/10, and Wednesday 6/11 in the upper 50's, or as high as the upper 60's with those forecasted 14 Celsius 925 temps?  Will this be broken mostly cloudy to overcast , or complete stratus overcast on your judgment?  I wonder if we get some true heat upper 80's + in here after day 6.  ECMWF sniffing out heat chance on 00Z 6/7/14 run.  Starting to remind me of the 1994 June heat and severe in the 6/13 to 6/19 1994 year.

my NWS forecast seems pretty normal, they are not predicting 80s after this weekend.

  • A slight chance of showers after 11am. Partly sunny, with a high near 78. Southwest wind 3 to 8 mph. Chance of precipitation is 20%.
  • Monday NightA chance of showers, mainly after 3am. Mostly cloudy, with a low around 57. Chance of precipitation is 30%.
  • TuesdayA chance of showers before 1pm. Mostly cloudy, with a high near 72. Chance of precipitation is 40%.
  • Tuesday NightMostly cloudy, with a low around 55.
  • WednesdayPartly sunny, with a high near 74.
  • Wednesday NightMostly cloudy, with a low around 54.

The lead is 4 to 4.5 days now, in the Euro, and it's managed to hold onto a pressure pattern that clearly shows a boundary passing into the area.  However, the trend has been to shallow the depth of the attending air mass. Below is the D4 (96 hour lead) off the 00z operational Euro, and we note the boundary passing into the area (annotation)...  

 

post-904-0-68261700-1402152368_thumb.jpg

 

Notice that behind the boundary over eastern Ontario and NNE, there is only a vague indication of a high pressure node?  Previous run(s) demonstrated more ... even passing a weak low pressure wave S of the region mid week.  That wave feature is gone as of last night, as we see above ... but the boundary still lurks.  

 

I'd like to see this boundary consistent on this particular 12z run (we're really only on the Euro's temporal boundary, after which its accuracy is impressive). The reason being, heretofore all we have had is a trend toward weakening, and until the trend stops, we can't really be confident in illustrating its affect on SNE.  The 00z run from the night before last night was deep enough with the backside BD airmass to even "dent" the 850mb temperature contours back SW a few degrees.  That would probably indicate your dip back into the 50s and very inverted sounding in the lowest 200 mb of the troposphere (or so...)  ast night's run does not ... another clue to shallowing out the BD air mass.  In other words, it's lost some momentum in recent runs as trend. 

 

So we'll see. ...   It is BD season ..well, pretty much every month in this part of the country, but late March through about mid June is a warm-weather duck hunt and BD's will form at least excuse imaginable; knowing that climo for our region, certainly the expectation is what it is.   My memory of the Euro's spring performance is that it's had a BD production bias -- it's nailed the ones that actually verified, but seems to have a default BD on it middle range charts at all times.  Ha, it's like scoring well with BDs by always having one.  

 

Having said all that ... as is, and using the Euro solution, that resolution above, to my eyes, would actually still provide 70F west of the coastal zones, to upper 70s in the CT R Valley.  

 

Lastly, 'technically' that's not even a BD above. It's passing in from the NNW, and fyi, the 00z GFS's version of this boundary is also weak, and approaching from the NW.

Ok. We will stop discussing our thoughts on the pattern and just look at the moosup point and click.

Can't really trust those pt - click values anyway, as they are defaulted off machine guidance/DB.   They can be manipulated ..., but personnel often don't get around to it. In quiescent times is a Met at an NWS office going to sense enough urgency to go in there and fiddle with the numbers?   Actually, when the sh t's hitting the fan, they can't, anyways.  I wonder what their job description is as far as doing so; it's gotta be in there, because the public uses them.  

 

I just have come to find that there is a fairly notable gap between internal discussion content and those values, and was told by a Met from an NWS office that those values are less than ideally populated.  In the plains, for example, though rare ... sometimes we'll get blizzard warning headlines going and the click-cast says something enlightening like, "Partly sunny with snow developing becoming heaving with extensive blowing and drifting.  High in the mid 50s"    zoinks  :wacko2:

 

'NWS doesn't seem to think it's going to be colder than normal'  - -haha.  J/k Steve
