Radian RTF

Radian RTF

Equipped with 3-channel control and Spektrum 2.4GHz radio technology, the Radian can be flown without the worry or risk of interference. Although a powerful 480 brushless motor enables initial launch, the propeller soon folds back to reduce drag, freeing the plane to utilize thermals of air to remain aloft, instead of batteries. That means flight times for this quiet and eco-friendly alternative are much longer than they are with traditional electric aircraft, making a relaxing day in the great outdoors even better.

Like all of ParkZone’s innovative and high-quality aircraft, the Radian looks great right out of the box and provides pilots with the control and reliability they seek in a park flyer. The plane’s large 2-meter wingspan and elliptical dihedral design improve flight performance and visibility from the ground, while plug-in wings provide for easy transportation and storage.

Not only does the Radian’s lightweight Z-Foam™ construction offer the perfect balance of weight and durability, it also makes repairs simple and quick. Since everything needed to get the Radian airborne is included inside, you are only minutes away from the ultimate soaring adventure.

Features

  • Spektrum™ DX5e 5-channel full range 2.4GHz DSM2™/DSMX radio system eliminates interference and the need for frequency control
  • Ready-to-fly right from the box – everything you need is included inside, even the batteries
  • Large 2-meter wingspan makes the Radian easy to see and provides an excellent lift-to-drag ratio

  • Variable rate DC cell-balancing Li-Po charger safely charges and conditions Li-Po battery
  • Powerful 480-size, 960Kv outrunner brushless motor for efficient power
  • Throttle, rudder and elevator provide true 3-channel flight and maneuverability
  • E-flite® Pro 30A Brushless ESC with Switch-Mode BEC for maximum performance
  • Durable, lightweight and repairable Z-Foam™ construction
  • Plug-N-Play® version also available (PKZ4775)

I have been out of sailplane flying for several years due to moving to a location that had no slopes or room to run out a winch line. I have been wanting to get back into flying and began checking around and came across the "RADIAN". I checked all of the reviews for this plane and found that a vast majority of them were very favorable. I just purchased my RADIAN and as all the reviews state I can concur the plane was ready to fly in about 2 hrs. 10 minutes or less to put the plane together and the other time waiting for the batteries to charge. This plane is truly great! it flies like a dream and is very easy to control. If anyone is contemplating a beginner plane this is definately it. I wanted something that was slow and simple for the relaxation and joy of flying, not to mention I have been flying so sporatically that I'm not ready for flat wings yet. Again this is truly GREAT!

After buying this kit, I charged the battery, and while it was charging I checked the balance point and prepared to go to the flying field... After charging the battery and arriving at the field, I assembled the glider, bound the radio to the receiver, and with another club member took a test throw to see how the glide angle looked.. checking once more to make sure everything was in order i turned into the wind and starting the motor, launched into the wind . . . It rapidly gained altitude, and after i had it at about 700 feet, I glanced, for 4 seconds at the most, down to the radio to attach the strap around my neck to the radio . . . Upon looking up, the model was gone!! Ii immediately yelled to the other club members to see if they could spot the model. None of us could spot it. I threw it in a southerly direction in a partly cloudy afternoon sky..we searched for 3 hours with no luck. Immediately after losing sight of the model, I gave the radio left rudder and down elevator..well to make a long story short, we never found it.....
Fast forward a month. I received a phone call from a club member, a man cutting his lawn a mile and a half away to the north (remember when last seen it was gaining altitude to the south)..had found my model!!! When it was returned to me, outside of a little dirt in spots, it was as if I had just taken it from the box. I took the origional radio, put in a new battery, and it started right up ready to be flown again!! We figured that after I lost track with it, it caught a thermal which turned it around, it flew for a mile an a half and landed all intact. We are in a drought here so there was no water damage and outside of a few cobwebs it was almost as good as new. I would recommend this model to anyone who is into gliders, a beginner, or anyone just wanting to enjoy a smooth flying, easy, fun model, and since i lost my first one I purchased another, so now I have two...this is a very good model, very good!

If this is your first plane, get a HobbyZone Super Cub LP or Mini Super Cub. This is certainly not the easiest plane to fly, but if you have some experience it can be. It flies great and looks wonderful. For me personally, it takes some warm up time flying it to get into the "zone". With this plane, the first think you notice is that there is a certain point where you control the plane perfectly and it looks amazing. The hard part is getting to that point, and that is why you need some experience.

On the advice of a very good friend I decided to go with this the RTF Radian. My first plane was a Mini Super Cub and after 3 months decided to try gliding. This plane excels at soaring and can get you catching thermals in your first few outings. Having a prop when needed is definitely a plus as a beginner with this type of plane. Also the plane is very durable and if required easy to repair. The RTF model has been great the controller and all accessories have been great. If you are thinking about trying glider out then I don't think any other can compare for soaring ability, user friendliness, and price.

I have been flying RC aircraft for a while now and if I ever want to just have cheap fun then I take my Radian out. I love it because I can try flying inverted and other simple tricks. The great thing about it is all the parts are fairly cheap. I have made many bad landing with this plane but I always just thrw it back in the air and it works fine. I would recommend this to a friend because it is probably the most fun plane i have ever owned!

The ParkZone Radian is simply a great airplane. It is advertised as being suitable for beginners. That might be the case as long as the newbie is hooked up to a buddy box until he gets the hang of it. I would highly recommend a couple of months flying a HobbyZone Champ and getting totally familiar with the Tx controls, landing, hand launching, and orientation in the air. Once in the air, the Radian is a thing of beauty and joy as it loves to float on even the slightest thermal. It climbs like a rocket ship too. Flight times on the provided battery are easily in excess of 25 minutes, and the Radian usually has to be forced to land for a battery check. The Radian is just a great airplane and is a very cool way to spend a relaxing couple of hours at the flying field. Just make sure you have plenty of room to land. Try it. You will not be disappointed.

While the build of the model is simple I managed to screw up by over tightening the elevator servo horn screw causing it to break. Lucky the local hobby shop had replacement control rods with the screw sets. I felt the quality of the entire kit was so-so. My controller had a braided wire which looped out of the controller and was trapped by the case. Not a big deal, but set kind of a bad impression.

The flight and flying was great. Very fun, stable, and lasted an hour and 15 minutes on two batteries. I can't express enough how much fun it was to fly at the local park.

I highly recommend this sailplane.

Second time I flew it, the control screw came loose and it took a nose dive. I made sure I didn't tighten it too tight because I broke the screw before because it's cheaply made. The micro control screw is the most important part on the plane and it is cheaply made.
