How do you even SEE your plane at 1500 ft? I hope its large!


You have to keep it almost directly overhead when that high, and it looks real small.


So how do you know if it's flying level, or even that it's flying properly at all? Seems pretty risky... Are you monitoring the video from the ground to keep bearings?

OK guys, here are the altitudes, A10FLYER, not too bad on the guesses!

TWINTUROSTANG, you're right on pics 5 and 8, real close.




Thanks....that was fun......and luck! I think I'll go play the powerball tomorrow!!!

The plane is a Multiplex Twinstar II and is a very stable platform IMO. It is trimmed out to fly wings level and best glide angle with power off. The plane will climb with power on. All I do is keep the plane flying straight in a particular direction and it should be climbing with power on. I usually do not monitor the video while in flight, if I do, it's only for a second or two as it is very easy to lose your visual on it. I do not fly beyond visual range, I want to know where my plane and equipment is at all times.

Glad you enjoyed it, it was fun putting the pictures out there and seeing the guesses.

What does your camera weigh?

Plus, I'm sure the 56" wingspan is a big help also. Most of the electrics are in the 35-40" wingspan range. A larger wing is much easier to see at longer distances, or higher altitudes.

BTW, I've got a Twinstar II on order with Tower. For now, I'm going to use that as my AP platform. Later on, I may make a custom fuselage and mate it to the twinstar's wing.

I have Googled this thing to death......WHERE is it?? The clues you gave lead me to believe it is in the southwest part of the metro area.

Next ?....do I know you? I get the feeling I do......
