Here's a new one I picked up recently from a guy here in San Antonio. Seems to work good and is pretty light. Less than three pounds with the camera.

It's a simple little mount with nothing but a shutter release servo. My Falcon 50 handles it with no problems.

The government cannot give you anything without first taking it from someone else.

I'm half way through stretching one of these to 1.76m and regearing it to take the weight of a dv camera and still do 3-d

Thanks Flyboy!

Hey I appreciate the assist!

PS... We are at an elevation of roughly 3000 to 3500' and are using the XCell gasser with the G23 engine.

Test flights are incredible but we have been keeping it low because we noticed a carb noise and brief loss of power. We made adjustments and that fixed it but were curious if a guy is worried about overheating what is the safest cure? When we richen the carb the gyro keeps twitching to compensate for the jittery surge of the motor, lean it out and the copter kicks butt but may be warming up. We are using (1 gallon) of whitegas and 2 oz of Amsoil)

We are limited on heli knowledge resourses in our town so here I am! A small engine mechanic who works chainsaws etc suggested a different jet for higher elevations.

I can email the first video which has audio and you can hear the change in engine noise at about two minutes of runtime, fully loaded with camera gear. My copter wieghs in at 20lbs even, with all gear. Simular wgt as another copter I seen online here.

thanks, Email is mecorp@hotmail.com

Sounds like...

If you're not using a governor...

One possibility is that you could be overspeeding the motor. Might want to turn up the pitch curve a little and turn down the throttle curve a little, that's the way mine run anyway. The motor likes to work hard but not overly fast.

Also, are you using the newer "pink stuff" Amsoil?

Bucket Cam

Here it is. A heli cam mount everyone can afford.
This unit is still in the R&D stages , when ready
you will be able to film and take multipile pictures at the
same time. R&D says this heli will be able to film at
speeds up to 45 mph.. (vertical that is)
Ain't she a beauty. The bucket can be used for filming
or carry the heli home after crashes.

hey cyber-flyer

i that the same ship that shot the chimney POV flyover?

Sure is a pretty ship when you consider the amout of equipment you have on that puppy!

I love your flying stance...

Same body, new soul

Hi Ethan,
Thanks, this is the same airframe, engine, blades, etc that I used in FPV flight to the chimney. But I've added quite a few mods over the winter. The front is rearranged back to use conventional canopy. Digital Sony MV cam sits on 3 axis gimbal with side mount from Rotorkraft. The gimbal is modified Rotorkraft G7 2-axis gimbal. Two channels diversity TX's both working in 2.4 Ghz band. Carvec2 - sweet gadget.
I've put few more pictures here:

I haven't flown this baby FPV yet, she has 1 gallon of fuel through it but I am still in the tuning and tweaking stage. I test flew artificial horizon indicator last weekend:

If the whole thing works - it's going to be my ultimate toy. I keep my fingers crossed.
Val.

And I thought my heli was a mess of wires and devices. what do you have just behind the rotor shaft? I think there is a GPS unit and something else more. Why do you need a GPS, and whats the other box (if its possible to be known)? and the video tx on the tail fin? or it isnt a video TX ?

I am guessing that the "box" is part of a diversity system as well as possably an autopilot? The Gps is also used for the gps video overlay.

I see atleast two video Tx's, the one that you pointed out on the tail looks like a 900 Mhz, and another cantilevered out on the boom across from the camera.

See the above post by cyber-flyer, I believe that he has been working with video and flying from the first person's perspective for a while.

A very talented indvidual to say the least. Nice looking set up.

Hi guys, thanks for kind words. She did come up pretty well.
Yellow box behind main shaft is GPS receiver (it will be hidden under canopy in the next "upgrade"). The box below hosts telemetry board (TL100 from Sky-Spy) and telemetry modem. There is no autopilot as of now - I tried to use PDC-10 for navigation last summer but results were not very reliable. Telemetry modem is made by myself on the basis of ATMega128 processor. It sends GPS data, attitude data from FMA's co-pilot sensors, temperature, RSSI to the ground station. Ground station uses GPS coordinates to lock on the heli with tracking antenna. Small box on the tail fin is 2.4 GHz 500mW Felsweb video TX. There is another 5W 2.4 GHz TX which is the silver box with radiator fins on counter-balance arm. These two transmitters send video on different channels of 2.4 GHz band and a receiver on the gound automatically selects the strongest video signal to display.
Big investment on this heli is Carvec-2 attitude control system which sits on the left from the canopy. I am starting to like Carvec-2 more and more as it proves to be a worthy gadget. Don't hesitate to ask - I'll answer if I can. I enjoy watching your pictures and videos - may be I can help with wireless set-up questions.

ok I'm asking questions...

still amazed by your "one-man" engineering! awesome.

I was wondering though why you utilize BOTH the FMA device and the Carvec? I thought the CARVEC did both altitutde and attitude? Are you using the FMA sensors just for data?

Also, since you mentioned 2.4ghz. I wondered what's the simplest way to increase range without having to point it directly at the heli?

I'm always flying out of range of the downlink

BTW: It's Poalris Industries GFR-2400 Rx and Tx

Range.

Ethan,
Simple way to increase your range is to increase transmitted power. The range increases as square root of transmitted power. But it can only be done to a point where the weight of amplifier, interference from RF and current consumption will put a limit. I'd say it becomes impractical to go beyond 5-20W on total RF power.
My experience is that using directional antennas is a more efficient way of solving the range problem. Directional antennas also reduce chances of multipath interference and video dropouts.
I only use co-pilot sensors to test a prototype of artificial horizon indicator. I am not using it for attitude stabilization.
Val.

sounds tricky given the horizon temperature variations.
