Good Vid

Surely it would be very nose heavy with a 2200mAh Li-Po fitted
even the the guy says
"hi there, yes 2200mah is a good all round battery - i recommend it if learning to fly because it makes the plane slightly nose heavy... cheers

I fly a Decalage moded Rad CG @80mm with a stock 1300mAh Li-Po ,
I once fitted a Turnigy 1500mAh Li-Po and had to add 10grams of weight to the tail , just to get the CG back to 80mm again

So theres no way a 2200mAh would be slighly nose heavy

If you look at our "his" other vids after he crashed you can see the carbon fiber rod he installed and according to Scott it has greatly improved his response and tail stiffness.
I said there might be some people who might think it was, but I was not one of them. Not one of them. Not one of them. I totally believe it is real, because I know how flexible the tail was on mine before putting in the carbon rod. The stiffness definitely adds to the rudder and elevator response.

I might add that I was definitely going a bit too fast for a catch but did it anyway- the canopy kept going even though the plane stayed in my hand- and the camera was mounted on the wing saddle looking at the tail- the pic was obtained from a frame by frame analysis and i grabbed the frame with the most flex...

original video with slow motion -jump to about 5:30 for the catch

Are you doing Radian research my good Colonel? I really think you would enjoy this bird- I swear it flies even better than our easystars- but i won't tell them that in the EZ thread- I like both planes- but on all but the most windy days- the radian will out fly- out glide- and out climb- the EZ while even being easier to control- and due to its larger wingspan- it is easier to see further out or up...

For some reason in heavy winds- (20mph plus) the Ez fights the gusts better- perhaps there is to much wing on the Radian (acts as Sails) or because the weight of the Ez is slightly more with less span- but the radian would be a great second plane for you- it was my fourth or fifth acquisition- and quickly made its way to the front of my hanger

Before changing the prop I could not maintain vertical flight and it would take 28-30 seconds to get to 200 meters
All I can say is the air must be better here in IA as with a 30 second flight up I would be well beyond 600' closer to my limit of comfort at around 1500'.

This weekend I need to time my flights to be sure just for fun along with video.

I thought I remember somebody saying there was a must do mod to the radian. Was it the control horns?

I am...... but it was the relative windy performance situation that has made me order the EZII in preference to the Radian at the present time. Round these parts, it is the wind that stops me flying most (well that & the rain!). However, the plan is still to sneak a Radian into the hangar by going in under the Senior Management's radar........

Sometimes Management must be kept uninformed..

Good for you- I swear you will love the plane as much as your others if not more-did I say that?

the control rod connectors are the most important- the stock ones just plain suck and are prone to failure....

Today I got a few of my Li-Po's out to test the CG on my Rad . .


For starters my Turnigy 2200mAh would not fit , so I opted for a 2100mAh..


To start with I fitted the Stock Parkzone 1300 Li-Po and balanced out my Radian, which has been Gorilla glued back together far to many times.


My Rad has had the CarbonTow Mod on the Fuse and I've got CT on the LE of the Rudder , Gold-n-Rods fitted , aswell as having the Tail Magnet mod for the Elevator ..


Stock 1300 Li-Po CG @ 80mm


1500 Li-Po CG @ 77mm


2100 Li-Po CG @ 74mm-ish

Dang Kids anyway ....and I still think 3D should be reserved for Movies

I am new to the Radian Party and WOW it's my New Favorite (out of 3 other EP- SP's an 'bout 5 pure sailplanes). In MHO you can Forget all that stuff about Decalage and worry more 'bout Cleavage . Just more the CG aft to 3.25" - 3.5" and Go Fly !!

Get it Up an Keep it UP

I was super impressed by that video of the kid hovering the Radian. For one thing, it must be even harder to do on a plane without ailerons. He said everything was stock except the battery but that motor sounded more like the Power 10 in my Corsair.

All that aside, what impressed me the most was how that skill could open up many more places to fly. There has been some talk about how to land in small spaces and different types of nets to try. If you could just cruise in and hover it and pluck it out of the air, you could take off and land in your back yard.
