ParkZone Radian Electric Glider for FPV


Have a look at this: http://www.parkzone.com/Products/Def...ProdID=PKZ4775

The Parkzone Radian looks like an ideal FPV plane and comes with brushless motor and 30A ESC. You can also choose a complete RTF Package with 2.4GHz 5-channel radio and lipo included. I spoke to our local supplier today who flew their demo model and he says this plane flies like a dream with vertical climbing potential and good handling. I'm definitely getting one!

Great! It looks like an Easy Glider Pro - only cheaper!

How does this "Z-foam" material compare with Multiplex' Elapor though? Electronics' quality?

Ooops! No ailerons?

Yeah no ailerons but I'm sure it can be added if you feel adventurous. There's a discussion about it in the RCGroups Sailplane Forum

Description of foam types found somewhere on the net:
"EPP is very hard to break. I have EPP planes that have bounced 6 feet in the air without breaking. But it is somewhat rubbery so you end up having to stiffen it with spars and shafts. In the case of many EPP planes, it is the supporting structure that gives the EPP some body that will need repair, not the foam.

Elapor and Zfoam seem to be about half way between the two in their ability to take a hit, stay in one piece and hold their shape. In the case of these foams, they may survive a hit but the foam may be dented so you need to have a way to expand the foam to return the item to its original shape."

Here's the PKZ 480 Parkzone motor. The ESC is from E-Flite.

Looks like a nice plane. Did you see it flying inverted on the vid?

I just watched the video now, didn't see it before. Looks like a really good flier. I wonder how it will handle in wind? And if it would perform well with ailerons added (Although I don't think it's really necessary for FPV on this one).

Those wings have so much curve to them it'd be hard to find a place straight enough to add ailerons.

I like it. Those wings do have a lot of curve to them, but I bet that could be remedied easily enough.

How would you get the curve out of them? Cut and paste?

So I saw the Radian in action today... very impressive! It climbs vertically with no problem, glides really slow, turns on a dime, and looks like an overall good performer. It looks and feels very strong and light. There's enough space in the fuselage for FPV gear. I'm definitely getting one!

I think the Eflite Apprentice has alot of potential for FPV also. The fuseage is huge and the 63" wing has some leading edge droops to aid low speed stability.

I redress the Easystar wing tip only by modeling them with my hand. I put pressure on the other side.
You can also use boiling water, just let flow some hot water on tip (few seconds) and add pressure with your hand

I didn't know you can do that! Maybe I should get an extra wing for the Radian and add ailerons...
