New personal Altitude Record for my Trex A/P!

Set a new personal altitude record this morning...1615' !! I'm sure others have gone higher, but for me, this is definately a record and was just on the edge of insanity being that it's a heli.
It involved my Trex 600, a strapped on Garmin 60CsX, and a lounge chair (for my neck!). I could have gone higher of course, but it was only a dot as it was, and didn't want to push the envelope any further. Next attempt I'll have my camera on board.

Arhhh you went all that way and don't have photos to prove it?

I assume you used some form of stabilisation? How long did it take to get up to that altitude and come down again?

Photos of the ground would not prove it, only the GPS would be able to do that (see pics attached). I was able to gain that altitude in less than one minute. Yes, I would never attempt any climb more than 500' without my AP2000i for sure - especially important when decending. To come down, I just dropped the stick all the way and let 'er fall - very cool sound btw...

How easy is the AP2000i to set up on the T_Rex would you say?

Pretty straight forward - Mark Webber from Webber Aerial Imaging can walk you throught it. Here's a few photos of my setup...

... you don't want to have a boom strike with that little gadget perched on top of the boom... isn't there a better place to put it?

That's the best place to put it because it has to have an unubstructed view all around. Besides, If my flying results in a blade strike to my IR sensor, then I have no business flying AP.

I don't want to rain on anyone's picnic, but GPS altitude simply is not to be counted on as reliable. Position, yes; altitude, no!

I've had this unit for 3 years now and has always been spot on for altitude. That's one of the reasons I purchased the 60 CSX. It has a barometer calibration feature that is extremely accurate when calibrated correctly.

Here's a quote from a techy product review:
"...In addition, this unit features a new, highly sensitive GPS receiver that acquires satellites faster and lets users track their location in challenging conditions, such as heavy foliage or deep canyons. The GPSMAP 60CSx also incorporates a barometric altimeter for extremely accurate elevation data and an electronic compass that displays an accurate heading while standing still."

Tight man.
Would like to get that camera up on her soon or even a vidcam on it.

Sorry - didn't realise it had a baro altimeter too! A camera would be good next time, if the heli can manage the extra weight.

Hi QuietRiot,
Nice machine!

I'm designing an AP machine from trex 600 parts:
What is the thickness of the tail rotor blades for the T-rex 600, is it 4mm or 5mm?
Do you know the diameter of the tail rotor shaft?
Also, do you know the diameter of the tail rotor blade bolt? (should I get tail blades with a 2, 3 or 5mm bolt hole)

My Trex isn't here for me to measure all that, but if you go to, they have specific specs on it....
