Hi this is my first plane with all servos install. Comment please

Job well done Rajesh.. Keep it up.. When yo are planning for the maiden 

Well waiting for the reciever may arrive Saturday .so maiden will be on sunday.malay bhai mote tike binding sikheiba

Good job Rajesh!

Why is the elevator split in two parts? That might lead to problems during flight.
Also, one of your ailerons seems a bit off.

Good efforts Rajesh. keep it up

I see no problem with the ailerons and don't commercial airliners have split elevator?

Well, commercial airliners are not made out of coroplast. Check the the 2nd pic for aileron offset.

@Topalle,

A single elevator is easier and reliable than a split elevator for a small RC plane. i agree even 100cc YAK, Edge will have split elevator with one servo for each.
The right aileron seems to be a little down when the left is flat. should create a flap effect when trimmed. need to redo the push rods to proper size. Overall the plane looks good and proportional in size.

Actually I found no way to use single elevator. Btw its nt double I have made a hole at the point you see and then put a rod inside it and connect the two elevator with fevi quick keeping them at same level.so when u move one elevator other moves as if its single elevator

That should work. To make a single elevator all you need to do is place the rudder before and above the elevator hinge.

Next time move the vertical stab an inch forward inline with the horizontal stab and give a 45deg cut to the rudder to allow movement to the elevator. this is the custom for most planes. joining the elevators with a rod is a good idea but why bother when there is better way. to the best try to make everything in one piece to give extra strength.

Thanks .btw I hadn't think about the 45degree cut .I will do it today

Your aileron linkage has got too much offset.

the servo horn and the aileron horn should be connected in a straight line - yours is extreme.
You will face issues while flying .

post a video of your maiden

I tried to fly my plane today .But after running 50mtr when it leave ground it just capsizes vertically.any suggestion please

Disturbed CG... Nose must be heavy

Can u tell what should be the ratio of wingspan length and fuselage length

Usually it is different for different designs and models. For a high winger like yours the chord length should be around 15-25cm, aspect ratio 5-7 and therefore fuselage 65-70% of wingspan. These calculations differ from model to model.
Please post the video of what happened during maiden. It would be helpful to figure out the exact problem.
Also, please mention the specifications of your model including all specs.
The above calculations are for a high winger trainer model as could be seen from pics you've posted earlier.

Ok its fuse length is25inch.and its wing length is 36 inch.its span width is 18 cm .im using 1000kv motor with 1000mah battery. And 9 inch prop.

Seems to be fine. Did your plane flew at all?
 Did you tried controlling it with elevator. Sometimes, little elevator has to be applied for take off. Or you could up trim your elevator little bit. Please post the video if possible.

No it just reached 2meters. Then capsized every time I tried.

What is the AUW?
Give a link for the motor and ESC you are using.

sanded the tail portion. Ans shortened the fuselage a little bit
Then my plane left tbe ground at a hight 1feet.as I feared to give full throttle. Maiden video soon

its auw is 380 grams

So did you flew it?

no.it just runs but doesnt take off

There is something wrong.
What are your flying skills? How much throttle you give during take off?

here is  my maiden video of my first aircraft:-
https://www.youtube.com/watch?feature=player_detailpage&v=dLiCL7PMGbg

have practiced in simulater in my android .and i give full throttle while flying

here is the second video

Looks like it's a bit heavy for the power system you are using.
Or maybe it's just ground drag. Have you tried hand-launching it?

Just saw the second vid. Looks like it's underpowered.

I went through the video. Following things are required to tell exactly where the problem is:
Agree with swapnil, ground drag could be a reason so try hand launch next time.
Please post the link for the motor you are using and also the battery. Is it a 2S or 3S.

Kindly post the link for all the electronics you used. If you couldn't find that then post exact details of everything. Battery, motor, esc everything. Looks like your model is under powered.

I have got turnigy aerodrive 1000kv motor. And 1000mah lipo with 9+5 propeller  20 amp esc all are 2cell

In one of your videos it is visible that battery is placed on the LE of wing. So, kindly make sure that the CG is balanced. Also, a bit nose down is preferred but if it is difficult doing so then no problem. Also, during hand launch you need to throw the model carefully. Since, this is your first time I would advise you not to throw model on your own. Ask someone else to launch it and you just have your hands over controls. It is difficult commanding both things first time as you don't know how the model would respond. Try to give full throttle and then only release the plane.

Friend there are so many thing that need to be covered while mentioning about motors. Max. current draw, thrust, max prop, voltage etc...

Otherwise give exact model number. See, you have to be very particular while mentioning the specifications and details because in your case that is urgently required. Otherwise, you'll just end up in breaking your model. A little search on net will do no harm for mentioning the details. especially for motors.

I noticed something else. You have too much up-elevator while launching. You need to trim that down. Also, maybe the plane is a bit tail heavy. Try a 3S Lipo with a 10 inch prop.

Ok I got that motor from Indian hobby shop on eBay .sorry im unable to send u the link

Just a moment. Let me check.

I think the seller has removed the item or must be out of stock.

Kindly tell the model no. or any pic showing the motor. Is it DST-1000?

Ok itss 1000kv max current draw 14amp thrust isc770 gram

Yes its that one u told

Ok its DST-1000
I would suggest you to go for a 3S battery. I hope you are having one.

770g thrust is for a 3s lipo with a 10 inch prop right? Are you using those?

Did you notice the up-elevator in the 2nd video? That's one of the major reasons for the crash.

Yes  it s that u told

Although prop size is not recommended on website still 9-10 prop could be used. In my opinion 3S lipo could make this thing airborne. Also, I'd already mentioned you need not launch model yourself during hand launch. During takeoff follow as:
1.) Have a proper control check of your controls.
2.) Ensure you have got fully charged batteries.
3.) Plug in the battery and give full throttle.
4.) When full throttle is achieved ask the other person to chuck the model. He/she needs to throw it or you can say push it in air. During this, you need not touch elevator. Yeah you can use a very slight elevator. Try out the following links for a better understanding:

I think you should not through it, let it run on the ground and takeoff to gain enough power, it will have a lot of drag I suppose
