Overview

The E-flite® Radian® motor glider is all about enjoying the serenity of soaring. With no Hi-start or cumbersome launch system to worry about, its built-in high-power electric motor system and lightweight construction delivers a soaring experience that’s hassle-free. The distinctive, 2-meter span elliptical polyhedral wing allows it to efficiently capture lift and deliver excellent maneuverability with the simplicity of three-channel control. The 480-class brushless motor not only gives the Radian glider outstanding climb performance, its efficiency with the required battery will allow you to climb back up to altitude to chase those thermals multiple times on a single charge.

The original ParkZone® Radian® airplane introduced many to the elegant simplicity of thermal soaring. Made of durable Z-foam™ material and equipped with a smooth, efficient brushless power system, it gave RC pilots a level of enjoyment that’s made flying with a glider the perfect activity even for grabbing a quick flight. This E-Flite® Radian motor glider carries on the design with improvements to the airframe for an even easier soaring experience.

Industry-Leading Control
The full-range Spektrum™ AR400 receiver installed into this E-flite® Radian® motor glider combines the speed and precision of DSMX® technology with the signal security of an active amplified antenna. This antenna enables the AR400 receiver to “see around” reflective materials, like the motor and battery, so you don’t have to worry about antenna polarization blind spots. It also allows the AR400 receiver to pick out your transmitter signal with remarkable clarity even in the noisiest 2.4GHz environments. All of this is complemented by SmartSafe™ failsafe protection and the security of Spektrum™ QuickConnect™ technology that provides lightning-fast reconnection so you can be confident of being in complete command.

Z-Foam™ Material
Exclusive Z-Foam material makes it possible to create a design that’s lightweight and surprisingly durable. Any repairs are simple to make with just about any fast-setting glue.

Bolt-On Wing
The two-piece, plug-in wings feature carbon-fiber tube support and the long-lasting security of a mounting tab that connects each wing half with a single screw.

Outrunner Power
The efficient power system of the E-flite Radian motor glider features an 960Kv outrunner, 30A brushless ESC with the brake enabled and a folding two-blade propeller.

Hummm...AR400 vs the original AR610. Don't know if that's good or bad or neutral. Mounting bolts for the wings, nice. Did the decollage change? Hard to tell in the photos but it seems to have move slightly up at the horiz stab leading edge.

Some nice upgrades on this Radian V2, yet should still retain the wonderful soaring attributes of the original. Unfortunately, looks like HH did not upgrade the prop assembly (same PKZ1018 part number). Was hoping this area would be made more durable to prevent thrown props.

Wow .... and I have had the thought of getting a real Radian rolling around in the head for several months, ever since flying my UMX one for the last 4-5 months. Glad I waited for the new one, almost ordered the older version last month, thankfully mother nature has had me grounded for over a month now .... flooding access to field and I haven't been ordering new stuff tooooooo much during that time.

Wing Loading Changed


If you look at the specs of the original post, the AUW with battery is 31 oz with a wing area of 551 = wing loading of 8.1 vs. in the 6's for the original radian...that can't be correct?

Just chatted with HH and asked if there was going to be additional reinforcement to the tail boom and tail surfaces, since those are standard mods people make to the existing design, and was told "yes, the new version has a much stronger and stiffer tail." Potentially good news, there.

Wow.. "E-Flite Radian" That just blew my mind.

They should have upgraded prop and spinner, etc.. though.

Not sure where you are getting that from. On the HH site they really don't give great specs on all of their planes .... and I hate that, so it is hard to compare, but they both appear to have same AUW and Wing Area. I didn't see the V1 model on the eFlite site.

I'm going to follow along. I've never bought or flown a glider but have been thinking about one for a while now. Is this the best way to start?

Tossing planes into the snow
This old thread gives the area of the original wings as 632 sq in, and a wing loading of 6.6 oz/sq in. I don't know about the accuracy of those numbers or where they came from, but that's what I've been using as a reference all this time.

Hey all,

Wanted to give some info on the new Radian.

First it is the same Radian you love. Flies the same if not a little better now.

Here are the changes:

Bolt on wing, makes the wing more secure on the fuselage and it seems to increase the responsiveness a tiny bit.

The fuselage is basically the Radian Pro fuselage with the fiberglass stiffener and reinforcement above the wing mount. Also helps with handling.

Clevis style pushrods, no more thumb screw keepers.

There are 3 new parts, the wing, fuselage and decal sheet, the rest use the existing Radian or Pro parts.


I have not tried to bolt Pro wing on this plane or these wings on a Pro. The tabs are different (much beefier on this new Radian) so a little modeling may be required to make them fit if the wing tube and tabs are in the same location.


As for the wing area, not sure where that number came from, but this is measured directly from the CAD and is on E-Fliterc.com and is the same span and chord as the original Radian.

Wing Area: 551 sq in (35.5 sq dm)


Hope that helps.

Thanks Matt

I did find the old parkzone page --- but of course --- they do not mention the chord or the area there either - as usual for some spec pages. http://www.parkzone.com/Products/Def...ProdID=PKZ4700

On the list ... I was going to buy the PNP since that was all you guys had left - and possibly put it on another brand radio, now I will have to clear 2 spots on my DX6i - one for this and one for the Pulse, both which I hope to get in the next 2 - 4 months.

"Radian Pro fuselage with the fiberglass stiffener "

Does the RP have a stiffer aft fuse where it is at it's narrowest?
If they did not stiffen up the aft fuse, they should have!

I'm glad to see this plane make it out of the Parkzone line that was eliminated.
