A great flight that never happened
#1
A long story.

About a week ago, I decided to try a flight at a spot I've been eyeing for about 6 months.  What I did though was go out to make the flight in a new area without doing any recon.  Well I usually don't do that and it bit me in the butt a little bit.

The spot is a mountain range in Southern Nevada.  And the specific target was to fly to the highest point in that range.  We can access the range from a dry lake bed.  This is the same dry lake bed you have seen me fly over when doing some long range testing.  Some of the dry lake bed and the entire mt. range is in a Wilderness area.  That means no vehicles, and no drones.  I knew this, but I was planning to fly from outside the wilderness area.  The airspace in a wilderness area is open game, but to take off or land, even crash land in a wilderness area is illegal.  Airspace use by drones over restricted areas is yet to be challenged in court, but other aircraft it is as I mention.  Anyway, we get out there and discover in the area we want to take off from on the dry lake bed is over 1 mile into the wilderness area.  We decide to make a go of it, as it is early in the morning, and law enforcement out in the area is sparse at best.  So we drive to the dry lake bed and set up at the edge.  I estimated the distance to the base of the mountains at about 1-1.25 miles.  I usually have a pretty calibrated eye for distances, mostly out to about 2000 meters.  Well my eyes were way off.  As we were flying out there I watched the feet rack up on the OSD until I reached the base of the mountains, for a total of 15297 feet, 2.9 miles.  Well, because of it being a new area and already being 3 miles in, and not knowing how much elevation gain would be needed, I bailed out.  I also blew judging how far the base of the mountains were away, so knowing how far the peak was set back from the base was unknown as well.

Below are a couple pics from the flight.  It would have been a pretty entertaining flight, flying up one ridge line and down another.  Also the view on the other side of the mt. range is pretty cool too, having driven on that side.  As it stands right now, this flight will have to wait until I get a wing/plane.

Oh, we got buzzed by a guy in an ultralight a few times.  Lots of that activity out there, but the Feds use ultralights for enforcement as well....so that tightened me up a little too.  My license plate was obscured by the tailgate, so if it was LE, we dodged a bullet most likely.

Actually, playing with ecalc, it looks like I may be able to pull off this flight with a 5000mAh battery (currently running a 3700mAh).  I may just get a couple 8000mAh batteries.  It looks like between 8-10k batteries are the biggest lipos for this platform before the battery weight exceeds the benefit of more mAh.  I need a big lipo to make my 15km run, so why not go big, right?    

But finding a C rating for a big lipo that's workable is a challenge.  For the mountain flight I need a 45C minimum I think.  

Standby.

You can probably get by on a much lower C rating. 8000mAh at 45C will give you a possible discharge rate of 360 Amps!

Hey, I fly fast!   Big Grin 

Actually, what I noticed in Ecalc is if I have a lipo of say 5000mAh and 45C, flight times are about the same as an 8000 mAh lipo at 30C.  But if the 8K lipo is 45C, then flight times go up about 35%.

I really don't want to do that yet....It's in my future, but it is a whole different level of stuff to deal with....I just want to fly.....
