Like I said in the "Silence" thread, I have been learning what is the highest altitude that I am comfortable flying at. I suck at estimating heights and distances and havnt installed my Carvec yet. Just curious if anyone can give me a rough estimate of my altitude on this shot. This is about my limits. Wasnt shooting anything in particular, just practicing.

High enough that you should be thinking about a full size aircraft.

What's that supposed to mean? I'm not trying to show off and I know I'm not above the 400ft limit. Trust me, I'm flying a Trex 450 so surely I'm not over 400ft. WTH?

Edit: Thanks Cranster

You should really be careful when you fly, that 450 is endagering peoples lives here! LOL

From Wikipedia,

" A standard water tower typically has a height of approximately 120 feet (40 m)...

http://en.wikipedia.org/wiki/Water_tower

So if you assume the tower is 120' and it takes another to make it to the horizon, the helicopter height is something just over 240'.

Damn Flyingeye, wasn't expecting that kinda research! I was thinking no higher than 250ft. It is definatly a challenge getting her back down. Do larger helis handle VFR better than smaller ones?

I'm impressed that you can even see a Trex 450 at that height. I'm just playing with you, nothing personal.

And the water tower's base is obscured, taking up some of the 120" average height, so I would bring Flyingeye's valculated estimate to 220'.

My heli works out great. I would like to one day step up to something larger. I figure it will be easier for me to go from something smaller to a larger heli. Granted most of my AP has been done from 100ft or less its still fun to go high. Just have to have "busy fingers" during the descent.

rerazor- No worries!

cute trick, but you have no idea the angle of the camera, the elevations of the land, etc.

why don't you see how big your heli looks, than lay it on the ground and walk away until it looks just as big, and measure that.

alternatively:http://www.alliedhobbies.com/catalo...&showprevnext=1
get a buddy to use that for $20. I've seen plans on line for free.

Actually, the angle of the camera and elevation of the land don't matter as long as the horizon is sufficiently "far" away. If that is the case, any object that appears on the horizon is at the same altitude as the camera (and helicopter). If you can infer the distance an object is below the horizon (i.e. length of the water tower) you can deduce how much higher the camera is than that object. This would not hold up if the horizon were "close" as in the case of a nearby mountain range.

Guessing height and distances are all about training.
In this case its hard to tell, you can be fooled by a wide angle lens, that makes the distance look even greater than it actually is, and then there is elevation and stuff.

If you knew the height, you can calculate the distance to the horizon by using a table.

Another method ive been using for guessing practically everything is the average method;
If you guess the maximun value, then the minimum, add that together and divide it by two, you will very often get real close to the actuall number, just try it in your daily life, guess someone age, temperature, or stuff like that, its amazing how close you get everytime

In this case by assuming the picture is in "real size" i would say max 300ft, min 150ft, which makes an average of 225ft

Or like Max and Noobs say, buy a cheap device from 20$ and up

Personally ive been using this which also works great and easy to use; http://www.blip.com.au/item.aspx?itemid=18

But soon i will go for a "full" Eagletree system

Never argue with an idiot, he'll drag you down to his level and beat you with experience...
