Not sure if anyone has seen this article

http://www.rcgroups.com/forums/showthread.php?t=1383846

and the video

The speeds make most of our jets look pedestrian. The first part of the video does not capture the plane much but the second part of the video that has slower flight at up to 406 Mph is better.

This plane was fitted with a data logger and measured G forces. Have a look at the file

This shows G forces peaking at nearly 90G and average is about 38G unless I misread the file.

Funny how they still trust 72 Mhz

Nothing wrong with 72 Mhz. 72 Mhz technology in R/C has been around longer than 2.4. I trust my radio equipment, I just wouldn't trust my reflexes.

Why wouldn't they? It was only a couple of short years ago we trusted 72mhz in 20K jets. Just because something new comes out doesn't mean the old technology is no good. I'd still take a 69 Camaro over a 2011 Camaro

where does the AMA stand on this, since jets are limited to 200?

AMA does not prescribe speed limits on anything except models powered by turbine engines. Weather or not anyone "cares" is another matter, but there is no published speed limitation on sailplanes.

That looks as fun as seeing how many touch and goes you can do on a tank of glow fuel on a kadet senior. haha

The other good reason for sticking with 72 Mhz on a plane like this is that it is probably mostly carbon fiber to be able to handle the loads. The 72 MHZ antenna plays a little nicer with all that carbon fiber. I am still using 72Mhz on my Stratos sailplane which has a fair amount of carbon in the fuse.


And yes, I would take a 69 Z-28 any day over the 2011 Camero.

I wish I understood why this question ALWAYS comes up whenever speed is mentioned for anything other than jets. Pointing fingers at another aspect of the hobby isn't going to get you any special consideration or changes to the turbine segment at all. In fact, all it's likely to do is to have the AMA or someone else getting their fingers into another group's enjoyment.

I watched the video any never saw any glider ?
Well the guy threw it off the hill and then it disappeared.

Yeah, maybe the camera guy was just panning the camera and making swooshing sounds! Nerves of steel, brass spheres!!!

As sailplane flyer, the speed issue with a sailplane is moot once they get out of the rotor on the hill. He can probably hit 200 in a dive if he's flying flat land. The sailplane cannot maintain speed like a jet does. Note also he is flying on a deserted hill, not in a populated area.

And DSing is all about the speed, it's like flying pylon alone. Some people like it, some would get bored with it after a while.
