Would any body know anyone that was selling a used R50 - Rmax or know where to find one. I am working with a group studying uav's and the current heli is a bergan twin and it's on the edge of it's limits. the Rmax is the only heli I can come up with that's bigger and more powerful. The Bergan is a nice bird but it is just a realy beefed up 60 and it shows.

Please any info will be appreacated

Have you checked Yamaha web site? The R50 starts from x10$$$ of a B.I.T. I can suggest Vario USA's CamCopter 5.1. It is bigger and can lift a lot more.

Those numbers do not add up my friend.

Actually the R-50 has been discontinued, The RMAX has taken its place.

Both of these helicopters have a ten foot plus rotor span and the R-50 carrys 44lbs and the RMAX is rated at 66lbs Payload, I believe that the SchiebleCamcopter 5.1 is capable of 20 lbs payload.

It is also interesting to note that the R50 and the Camcopter's total weight, are withing three pounds of each other(148/145lbs) but the R50 will carry over twice the payload. Not to mention The R50 has the YACS system as well.

The 246cc, water-cooled, 2-stroke, horizontally opposed 2-cylinder engine has been developed by Yamaha specifically for the RMAX application. The light, compact, yet surprisingly powerful 21-horsepower engine can handle 30 kilograms (27 kilograms on the model with GPS) of practical payload, which is the largest in the industry. Because the engine is water-cooled, it brings its power into full play in a stable manner, even in high-altitude areas or in the scorching sun.

How many Rc helicopters do you know of that have flown an IMAX camera on them?

I don't know about the Scheibel 5.1 but I've seen Schiebels carry a whole hell of alot more than 20lbs. Also, Scheibel does have autopilot systems, that work very well, but I doubt most could afford one.

We have lifted 20lbs with just the robinson R-22 mechanics (w/o fuse). Stock everything (G230 engine)

I have been told that Vario has 2 more helis bigger and yes, the 10ft span camcopter is supposed to lift 60lbs out of the box.

Rmax Certified!
I completed Yamaha's low-level flight certification on the Rmax last week. It was a blast. Did several days with the trainer cord, then we soloed on Thursday afternoon. The training follows the steps Yamaha uses to teach the cropdusters in Japan, basically flying out and back tail-in, learning to pass over cones on the ground at increasing distances. We also added some close in Figure 8's and extended side-on hovering (all three of us were R/C fliers). Friday was pretty windy, but we took it up and tried the different YACS modes (with the instructor back on the buddy box for safety), including turning it off. That was a little hairy, but it was good to get a feel for it in case the system goes tango uniform. The yaw gyro supposedly goes into rate mode with YACS disengaged (it's also the only one active in that mode), but it didn't really feel like it, the tail seemed to stay locked as in HH.
It's an awesome machine. Can't wait to take it up again, probably next week. Only get a good hour+ flight time on a tank, but the fuel is cheap!
