That was with four 1300 lipos. Please note I cut my runs early and leave plenty of charge on the lipos so I'm not sure it's a really good indication of the Radian performance. Not sure about the number of climbs and some were gentle climbs, fast climbs, and just "goofing around."

Thermal performance was pretty good yesterday and I could easily float in the sky for just about as long as I wanted. After awhile, I just have to bring it down before I go blind from staring at the bright sky for so long.

What about using a pair of these

The poster in #7555 added flaps, and the sub-thread about them starts there.

Oh, I've got my shades on. I'm afraid that's not enough for these aging eyes after staring at a glowing orange dot in the sky for over half an hour at a time. I'm talking the Radian, not the sun.

Mine flies great with a 2200 blue lipo. It's pretty light, so i can still thermal. Give it a shot!

There is nothing worse than flying a plane at high altitude on a bright sun day with no shades on cos thats when you can see the dreaded floaters! floating around in your eyes.

Well, I came over to the dark side. I have a Radian on order. This will be my first powered glider. I currently own a GP Fling, Spirit, and BOT. The reason I ordered the Radian is for those times that I just want to head down to the park after work. Or at locations where I just can't fit a Hi-Start. I have the PNP model coming. I have an AR500 RX. But, its my understanding this RX is for park flyers. Any problems with this RX/Radian combo?

The AR500 is the Rx that comes in the RTF, Original Radian. It's a full-range Rx. The AR600 is the Rx that comes in the Radian Pro. It, too, is a full-range Rx.

I am curious to hear your "review" of the flying characteristics of the Radian, compared to a traditional, non-powered glider. My Radian is my first RC sailplane, and I've found myself intrigued by it. I love the subtle, yet significant challenges that the plane has made available to me. Energy management, thermalling, duration flight, etc. I'm curious if there is a significant reason to upgrade to a traditional unpowered glider, or if the (relatively) inexpensive, easy to fix, versatile Radian and Radian Pro could address all my future "glider needs". As with most, my life doesn't have a lot of time for building, much less flying...so I like to have something flight ready whenever I have a spare moment.

The ar500 is a full range rx. I have had my radian over half a mile away with no issue. I was up 2600 feet on the altimeter and out in front of me probably 300 feet.

The ar500/dx5e combination will go farther than that. You'll lose visual contact with the airplane before you lose radio control. I've tested mine to a mile on the ground (with clear line of sight using a hill), just for peace of mind. I've since changed my Radian to an AR6200 (with satellite receiver) and my transmitter is a DX7, and that combination goes well over 2 miles, but I don't know if the stock setup will go as far.

I use to love flying a Gentle Lady which I would launch with a hi-start. After flying the Radian, the Gentle Lady may finally be retired. It's just really nice to be able to fly without having to use the hi-start and still get nice sailplane performance for relatively little cost and minimal hassle. Your sailplane interests and requirements sound close to mine.

I know it has more range than that I was just providing a real world example of what I have done with mine. A half mile is fairly extreme range for a 2 meter plane. People that have seen me fly numerous planes say I must have bionic eyes because of the range I fly at and the things I do. I have a 9503 fwiw.

The Gentle Lady was my first introduction to Sailplanes. There are a couple major reasons I chose the Radian as my first powered glider. First, there is almost a cult-like following. This thread with over 7600 posts says something about the Radian. I figured this many folks can't be wrong. I've been researching the Radian for almost a year. And for some reason I keep coming back to it. It's kind of like the Blade MSR Helicopter of planes. There are also days where I can't get to a field that has 800' of open area to set up my Hi-Start. Or the wind is just coming from a direction that doesn't work out right. There are some days that I only have a "block" of time that I can set aside to fly. My quick-fix before the cares of the world mess the day up.

The motor for me only serves one purpose; to get it into the air. I don't have any interest in buzzing around. Once I get up to altitude, the motor is going off and I'm hunting for thermals. One of the major advantages of non-motorized sailplanes is their ability to fly all day long on a single battery. A motor eats up a battery real fast. I know on my electric Super Cubs I'm real lucky to get 10 minutes of flight if I go gentle on the throttle.

I don't know if a traditional Sailplane is an "upgrade". But, there is a beauty to a non-powered Sailplane. I love the sleek lines, the absolute quiet, the way the suns glint off the covering on the wings and sheer relaxation. I think my Bird of Time Sailplane looks amazing. I've seen motors put on them and IMO, it spoils the lines of the BOT. I think the primary objective of Sailplanes is aerodynamics and lift. I love the so called "gas bags". And a prop on a Sailplane will always create some sort of drag.

Setting up and using a Hi-Start or Winch takes time. I think this is a good thing. I know this doesn't seem to make sense for those of us who have so little time to spare. But, as I get older, I find that it makes me slow down and just enjoy the free time I do have. I mean what's the point of staying so busy that it just sucks the joy out of life. "Pure" Sailplanes help me put the world on hold for a time. Once I get a few hours of flight time invested in the Radian maybe my philosophy will change.

Well, now you have the Zen of Sailplanes according to Curtis
