| This is a complete aerial photography platform as seen at 2006 Mayday fun fly in Sulphur Springs, LA powering up 250W automotive headlights Camera mount that comes with it is a modified HSC Pro60, equipped with one-of-a-kind vibration isolation system (see pictures). It serves to dampen vibration and shock during landing, and provides constant isolation in 6 degrees of freedom while airborne. There are no more bungee cords or straps to worry about. Isolation system is resistant to weather and chemicals and is designed to dissipate vibration through micro-friction.
Helicopter power train is also on-of-a-kind. It uses a modified Zenoah G231 with a custom crank shaft and electronic ignition. Stock ignition (magneto, coil, pickup) have been removed to provide tremendous weight savings and eliminate magneto vibrations. Crank shaft machined and fitted with flexible spider coupling – used in the past to transfer torque to a custom-wound generator that was mounted inside the magneto cavity on the bottom end of the crank shaft.
9CH JR PCM receiver, batteries, and the generator circuitry are mounted on their own vibration isolation platform in the front of the chassis – this will eliminate any potential problems from engine vibrations and keep your on-board electronics safe.
There is over $6,500 invested in the helicopter setup alone, and much more in the development of everything that is mentioned here and accessories.

This helicopter was recently crashed from a foot off the ground when a JR 8311 servo cyclic servo stalled causing the helicopter to pitch slightly forward and hit the blade. This was without all the AP equipment on or installed as I was still adjusting the helicopter.
DAMAGE REPORT:
1 JR 8311 servo gear set
Main Blades (tail blades are perfectly okay)
Skids
Tail boom/torque tube
Main shaft is probably bent (althought I haven't taken it off to check)
Washout Base arms
Flybar
And the tail fin
Canopy paint has 1" chip but the fiberglass canopy itself is in tact, no cracks , just that one spot where the paint is chipped.
Asking price $1,750. I would like to present this as a complete aerial photography system. Willing to sell the helicopter and/or electronics separately and part out the rest. We are located in Welches, Oregon. PM or call me on my cell phone
This is an amazing deal and you'll get a complete AP system for CHEAP!
