Default Radian XL Pros and Cons

Hi Guys.
I'm looking at the Radian XL. Any have any experience with this plane. I've flown the two meter radian extensively and am curious about this one. Any comments about good and bad habits this plane has would be greatly appreciated.
Thanks in advance for your input

Having just spent an evening flying several incredibly enjoyable flights on the Radian in calm, light lift, the Radian XL would make an awesome pick.

Default Carbon Fiber Wing Joiners

Howdy folks,

New here to the scalesoaring forum. I fly the Parkzone KA8, Radian XL, and am currently working on a TopModel Marabu. Just getting into soaring but I have been loving every moment of it, in an odd way it reminds me of sailing with Dad on a hobie 16 we refurbed.

I've been really enjoying the XL, however as many of you have commented its a heavy piece of foam. One area that I found to save some weight is the yellow fiberglass wing joiners supplied with the kit. They weigh in at around 130 grams according to my somewhat-accurate scale.

Over the past couple of months I've been experimenting with carbon fiber wing joiners. All four of them weigh in at ~40 grams (my scale is only in five gram increments) so they save around 90 grams worth of weight total off of the plane. This weight saving is also decently far out on the wings, so it has made my radian more roll sensitive in terms of detecting thermals and other little bubbles.

I've made them out of two sheets of 0.5mm carbon fiber which sandwich 3mm epp foam. This makes them just slightly thicker than the stock heavy fiberglass joiners, so as a result they fit snugly in the wings. Interestingly, I have had no need to use the wing screws with my plane as the joiners keep them together really nice, so that saves a step and is one less thing to forget on the way to the field.

I've got the process down to where it takes around two hours for me to complete each set. I couple local guys have asked me to make some for them along with some folks on another forum, so I figured I'd jump in here and see what you all thought. More info can be found at my website, AvemRC.com. Click on 'Upgrades' towards the upper-left of your screen.

Anyways thanks for the read and I've love to hear of other ideas to really maximize the performance out of this plane Name:  smile.png

I love my Radian XL. I been flying it for over two years. It’s my 2nd rc plane of any type. First being a Goldberg Electra I built in high school 20 years ago. The radian is so easy to fly I dear say it’s good for even begainers. You’ll love it.

I did put a carbon rod down the front the vertical stab into the fuse and one from the tail cone out past the impinge. This stiffened up the tail a lot. With great effect too. Also I replaced the elevator servo with on that has mettle gears. This all added hardly any weight. It the servo is a bit weak and is suspected to be the cause of may crashes as the gears strip or lock up.

Buy one. You won’t regret it.
