I would like to have a Radian but don't want to buy the RTF version, so am thinking of building one using individual "spare" parts (fuselage, wing, etc) and adding a power pack and electronics I already have. Any of you Radian people see a problem?

I have the Radian myself, and well..crashed it hard the last flight. So, now i'm waiting for my parts to come in to get it flying again.

I did order a Bare fuselage, along with other odds and ends. I don't see a problem with it, may be cheaper then buying the kit, i'm not sure. Only issue i might see is your servos be too big or small to fit...other then that, can't see anything.

If you do order a Radian Fuselage, it does come with a few things attached already. I'm telling you this, because i spent 2 weeks, on the phone and emailing product support at Horizon Hobby to find out exactly what is installed.

- Firewall installed
- Rare earth magnets installed (for canopy and access panel underneath)
- The access panel itself is installed
- Horizontal Stabilator (elevator) plastic mount i believe to mounted, but not mentioned in email.

and i'm not sure exactly, for it wasn't mentioned in the email as well, but i think, the velco straps for the ECS and Battery are also installed.

hope that helps, good luck on the build, let us know how it works out.

Cheers!

I have a Radian and this bird is the best. We have launched it (5mph wind) and 42 seconds it was 1932 ft in the air (used Eagletree altitude sensor) with a 1300 mah battery. I would suggest as long as you have a good motor, weight is about the same, and match the CG you should have no problems. Make sure you get the downthrust and right sidethrust in the motor so it launches properly.
The new Radian has ailerons added, you really don't need it and it adds weight which lowers the L/D ratio.
I like to design and fly unique planes.

Thanks for the inputs. I figure I can buy all of the parts for around $100, vs $160 for the ARF. I think I will give it a go but it might take a little while to get it all together. I will update when done.

Radian Man, I sent you a PM on this but here is the question. I need to choose a motor for my Radian and hope to use one that I have. What is the size (diameter) and weight of the stock Radian motor? None of the spec sheets I have found on line give that information.

I sent a reply PM, however i guess you didn't get it..so here it is again:

Hey dude, k did some research for ya.

The motor is a 480-size, 960Kv outrunner brushless

Weight: 87g (3.1 oz)
Overall Diameter: 35mm (1.40 in)
Shaft Diameter: 4mm (.16 in)
Overall Length: 33mm (1.30 in)

Please remember these are approx. but pretty accurate.

hope that helps!!

cheers,

Thanks Radian Man. It looks like a Turnigy 2830B, which I have on hand, might do the job. It is about the same size and weight and per the specs might have enough thrust to hover the plane. It might be a good spare for you or other Radian flyers. The cost is way cheaper than the stock replacement.

actually the actual size of the stock motor is

Weight: 105g
Overall Diameter: 34mm
Shaft Diameter: 4mm
Overall Length: 42mm

Of course the stock motor is rather bulky and heavy compared to the power you really get. I have use a scoprion 2215-18(62g) with a 10x4.7sf prop in my radian, and it gave me more power than the stock motor did. So i would recommend a 200w motor that can swing a 9-10x5 folding prop along with a 9-10x5 folding prop with 50mm spinner/hub set.

I appreciate the inputs but 87 grams or 105 grams? That is a big difference. Which is it? Did either of you guys actually weigh it?

yes, i have a scale, all test i have done on my own. And compare to other peoples specs that have been posted.

87grams is the weight of a Park 480 motor.

I would not advise you get that motor (turnigy 2830) it burns out with anything bigger than a 8 in prop. Here is a pic of how small it is...

DO NOT USE THIS MOTOR
EXI 450 V2
PZ Trojan
HK Corsair
Extra 300 3D
HK 500GT (not built yet)

Thanks for the warning but I have one and am using it with a 10 x 4.7 inch prop and a 3s Lipo. It works fine and has shown no sign of overheating. There are a lot of reviews on the HobbyKing web site,almost all very positive.
