So depron filled wings work well :p

 

Well then, let's drop it. I'll continue using depron filled wings.

Try using chemicaly expanding foam. Make a mould . And that would yield excellent foamy plane with lesser joints , weight and weaknesses.

But that would end up costing too much I guess.

But the expectations are also high . So a highly capable platform is needed.
What seems a bargain in plane's control and wing area . Is a quicky 300. That consist of 2 sets of wing .

Just increase the wing chords suitably.

 What do you want me to learn from that plane sir? Use the same design maybe?

just go with the depron filling route  

I mean u wil get 2 wings and more area for panels .

Yes, now I do understand. The Rutan quickie, the plane which Mathur sir recommended, is one of the most efficient planes in the whole world. It has 2 sets of wings, one low wing and another high wing.The low wing also has the landing gear fixed to it. I am very excited.

Maybe it is the perfect airframe for the purpose. Maybe it is.

But without scaled down plans, building it is not going to be easy. We will have to scale it down by ourselves.Let's try.

Try to obtain 3 view drawings and make up your own plans in sketchup.
There are tutorials on utube.

Hey ,
What are the flying charactersticks of that plane?
Be sure that when you build it,
It does not become a aerobatic model.
You know; the cessna 150 is a trainer originally but as you convert is to rc ; it becomes a sport model .
This is because:
Suppose the real plane requires x density of air to fly as a trainer. If you scale it down; then the air density also has to be scaled down. But we fly rc planes in that same density air. This is (almost) the reason for real trainers to become rc sport planes.
First ensure that the plane you are building will be suitable for a beginner.
I am sorry if i have said anything wrong.
Regards

Karthik ,i am jus 18.
Back to question, just make 2 same wings. Make a nice fuse. Add rudder to it . Thats it.
Prabal my friend . I fear for what dual rates, end points and expo is meant for .

If thing really go bad , use a 401b gyro. 
always remember calm winds never make a great pilot.

i was thinkin' you guys were planning to scale down that same plane

Yeah i am talking bout the same plane 'rutan quickie '
its the building techniques.
I think depron shall be the right material for the plane. Though it shall need wing reinforcements. Experts correct me if wrong.

I presume that members offering suggestions have personal experience to validate whatever they are suggesting...

Uh oh i had already  made this plane but not rc it was meant to be a chuck glider  . What i made was a not perfect but did glided well.
Just one problem with this design is its cg position .

However this plane suits this project . But for sure not a first timer's cup of tea . In fact it took me 50+ chucks to perfect the cg.

So it is a difficult plane to build. Though it has high efficiency, its chord is small. If Burt Rutan has done something, it would have a purpose. I think that if we change it we won't be able to get that same efficiency. Maybe we can use this in the later stages.

Good news:
I have found an Indian online seller of depron. Its Rc Bazaar! Even the 12x3.8 prop is available there! Yay!

Bad bews:
I was not able to order the maxeon cells because they were out of stock. Maybe they'll be back in a few days.

So for now, let's settle for a simpler airframe.

@ karthick
are you still considering the big old foggy plane?
Check out the ft simple soarer. plenty of wing area. even though the wing has one break in it;
the plane is still considerable

I have mentioned the simple soarer long back. I think we need to scale up the plans for that. But anyway, lets try. First of all , let us consider the pros cons of everything and come to a final decision. I will post a tabular column of all the pros and cons tomorrow.

I am leaving old school as I am moving to Chennai. I like my old school very much and the people at my school also like me a lot. I have been saying things about my aeroplane for a very long time. So i wanted to do a live demo.

I have this Kfm - 4 aerofoil based flying wing which I built. I have planned the show on 24th of this month, which is a bit close. So I am in a hurry to get things done.

So I am going to make this flying wing my first plane. I have no other go.
The weight of the airframe and the electronics and the DT 750 is 950 grams

So I have selected the 9x4.7 prop which gives around 750 grams of thrust at 9.5A.I found that propeller and 3.5mm connectors on ebay for around Rs450 ( 2 gemfan props(genuine) and  12 3.5 mm connectors with heatshrink)

please advise me on my next step.

The problem with rcbazaar is that the 3.5mm connector is out of stock. All other connectors are out of stock. At RCB one prop costs 95Rs.
