I am considering adding a turbine to the quiver. My little 10 pound electric heli is working great, but I also want a big, heavy pig to haul a full size HDV camera and other stabilizing mechanisms.

So, for those of you with real time experience with turbines, can you help me with some questions.

1. How do they perform at altitudes above 8k. Have you flown above 8k?
2. Anyone working with a Bergen Turbine Observer? I don't like underslung mounts, and would prefer a prefab front mount system.
3. What is the learning curve for working on turbine systems? Lots of tweaking? Or set it up and forget about it?
4. What is the real deal, no bull_ _ _ _ safety issue with turbines? I only fly in non-populated areas. I'm not into taking pictures of houses, or flying over crowds of people.

Thanks.......

I'm currently leaning towards the Bergen because it's clean looking, and appears to be well built for it's purpose.

I've been flying a Bergen industrial turbine. See my gallery for pics.

I have flown it at 6000' (density altitude 8700-9000' ) at 36 pounds total weight with no problem, other than some main gear wear (the nylon bergen main gears) at around 15-20 hours. Flight times in these conditions are 13-14 minutes on 66oz Jet-A (flown until the two main tanks are empty, UAT still full). The new Wren heavy duty fuel-lube gearbox is working really well so far.

I know someone who has flown an industrial turbine at altitudes >8000', PM me for info.

The learning curve for turbines is easy, probably easier than learning to tune a nitro engine properly. You just have to keep track of the order of things, and not to leave valves in the wrong position. The auto start jets are easy. Manual start jets are not. Buy a good CO2 fire extinguisher and ALWAYS keep it on hand. You will eventually use it. The engine starts easily, and will basically shut itself down safely if anything is wrong. In most cases the ecu will tell you the problem. I haven't noticed any ecu setting changes going from sea-level to 6000', nor from 22.5# to 36#.

Otherwise, the heli flies the same as any smaller "hobby sized" machine. You just have to remember that you're flying a heavy bird with basically a 60 sized rotorhead and a large disc (I'm using 850's, but it can handle 890's). Don't horse it around. You have to make smooth throttle inputs otherwise the turbine could easily overpower and smoke the clutch or strip gears.

The heli at sea-level with no payload (~22.5 pounds flying weight) is plenty overpowered. At my altitude and at 36#, I had to bump up all the throttle points about 5-10%. It flies very well at this weight - not scary or on the edge, plenty of performance margin although I certainly am not up for shooting any autos with $50k worth of electronics on board (and I LOVE autos!).

Call Chris Bergen, I'm sure he would be delighted to talk to you about his turbine observer. He's a first class guy, and Bergen customer service is second to none. PM me for more info. Wren Turbines is also an excellent company to deal with.

If you were wanting to fly a turbine in a congested area to take pics of houses, etc, I would suggest strongly against. When jets crash, they explode and burn. If you'll be in a non-populated area, it would be fine. Just keep the fire extinguisher on hand, and have a spotter ready to use it if necessary.

Interesting insight Eric

Just being nosey, but what's the black flight-case object on your Bergen Industrial Turbine? What do you use the heli for?

Thanks,

David

The black box houses a computer and comm system, with two cameras up front (color & flir) with imu, for vision software research to support a video aided navigation project. Autopilot integration and perhaps a pan and tilt is slated to follow. Basically, it's a testbed for UAV research, that we use for multiple programs.

Man Eric I want to come work with you! Awesome setup!

Remember when flying inverted that down is up and up is EXPENSIVE!

Just go get yourself a degree in software engineering and apply for a job!

If there were enough UAV jobs for everyone with the skills, there wouldn't be an internet. It's an addictive hobby once U get used to spending huge amounts of after-tax money and don't tell your boss about it. For it to become a career, a country has to be fighting for its life, which US certainly isn't.
