Dear friend,
Well where are you located... I am at Allahabad and am flying my models well enough though a bit jaded because of a long long gap.  You may call me for any assistance you may need... from material to building the model to anything you wish.  I would be happy to share everything with you.
regards

Bunty ,

19000rs is too big in my opinion and if you havent flown anything now then its very bad,
as rightly suggested by shobit sir, use plans that has already been tested and proven instead of jumping to your own plan,
with the pics you have posted i see you have the right setup to start with. its just that you need a good model to put these on, have a look at my glider that i just completed and flown successfully if you need any info.

No you do not need to crash your models... just get a simulator... (some 9-in-one sim are available for a few hundres rupees at various RC shops), practice on them and fly well...

@shobhit17

                    Sir I already have simulator which I buy from rc bazaar I am not using it  , I also know lots of plans which is available on internet, there are lots of simulator  which cost 1000 rs and are very good to learn flying rc airplane. After that there is skysurfter at rc damaka and rc bharat to buy and I am ready to go……

You know sir it is very very easy way

I am scratch builder I love to build airplane using material around us or which is easily available and I really enjoy it.

Sir chances of success is very less here but I will try again and again
When I will be tired doing this I will buy new simulator and sky surfer everything will be okay then .i know it.

I have a 2200 mah 11.2 volt lipo battery can I make it to 7.4 volt battery so that I can use it in my setup .
 
If not possible then I will buy new lipo …
Any alternate wood of balsa pls let me know if plywood, new wood or any other light weight wood can be used to build airplane other then balsa

i consider the weight of the airplane should be around 200 to 250 grms for the setup i want to build

i think only missing in my setup is prop and lipo 7.4 volt

JM 6x4 /152.5x102mm propeller - 1 Piece


ZIPPY Compact 500mAh 2S 25C Lipo Pack

Bunty,

the key for a successful model is weight instead of power, keeping power high with too much weight weight will get your model nowhere, atleast it wont flies that great to give relaxation. keep the model light and first perform a glide test before a powered launch, and use a proper motor/Lipo/Prop combination, small capacity battery will give more time with a lighter plane instead of 2200mah one. select/buy the motor after you complete the model and ensure it can lift the weight. i can PM a good combo of power system and Plan that works well if you need it.

@v2 eagle


                  very true sir , i am totally agree the weight should be very less thats why i am planning to build airplane weight in between 150 - 200 grms , and also i am seraching light weight battery to weight approx  40 grms. so as to increase the chances of success ,

 sir i am planning to reduce the extra weight i will fly without using landing grear. also i will work with 2 sero only for elevator and rudder controls (instead of 4 , 9 gms servo ) ie two exta servo for aileron i remove it so as to less the weight to carry by model

sir you suggested the glide test that is the way i plan to go

i am planning to use high wing with good dihedral (VERY LOGN WINGSPAN)

        sir i have everything just i have to buy few props and a light weight 7.4 volt 800 mah lipo
and there after i am all set to go........

your support matters a lot to me ......

Just great,

if you are going for a EMAX motor go for 2822 or 2812 instead of 2805. you can get more power for the same price and weight.
i myself run my 3ch glider on 2812 and can do hover. also ele and rudder and no aileron is a good move as you do not want to mess up with extra controls ruining your flight. all the best.

 I  want to know what should be the weight to thrust ratio I should maintain so as to make my airplane able to perform hover maneuvers , and as the prop size is increasing I am bit concern about the torque produce by the prop. What should I do to counter the torque?     Head Scratching

I do not want to perform hover maneuver but I want power close to this ratio so as the possibility of success of model increases.

I am very slow this time but want this time very good setup to build airplane , my airplane weight is going to be approx 150 -200 gms. Without equipments.

        The  existing motor produces 450 gms thrust with prop size 8x4  which I think is okay for the model
Sir
         The emax  motor suggested produces 730 g thrust at 15.5 A at 11000 rpm  with  7x6 prop size

The existing weight setup is good with 7.4 volt 500 mah the battery weight is approx 37 gms.

Also I am searching possibilities     Roll Eyes

  Of  motor which can be fitted on my existing battery ie 11.1 volt 2200 mah 25 c lipo and also can I use my 20 amp esc or I have to buy new one. The motor which produce lots of power with my existing 20 amp esc…..

is it possible to get 1 to 1.5 kg of thrust from the motor with my 11.1 volt lipo
It could be a different setup.

To be frank,
ive seen the avionics motor in action and it really is a useless motor.
right from motor mount, prop saver, everything is dispropotionate and really takes some patience to set this up.
OTOH you have various options for motors. for a good plane you need to have a reliable power train and radio setup.
get some good motors like turnigy/hextronik/emax that can produce good thrust reliably. also looking for hover at first flight is too much in my opinion.

here are some steps you might consider,
fabricate a plane first and put some glide test on it.
look for some reliable power setup that worked for someone else instead of putting lot of money experimenting.(for 19000 i would have flown atleast 5 planes)
once you have the confidence, experiment with different models and setups and by that time you will have all the knowledge you need.

All the best.

v2 eagle


by the time i got your post i order new set of battery and receivers now buget goes to 25000 for experiments and i do not have prop. to fit in setup , what ever you are saying seem me absolutely right
it is 100 % right , i think it is time to stop spending money and buy a trainer airplane but

there is what will be the success rate if i fly on my own.


i really want to keep this hobby alive but really i think i have to skip thinking about this hobby for a while
because of the wrong decision taken by me .this is good amount of money i place .

still i am ready to spend money but i do not have you know good setup which assure me


now i am thinking about ebay.in (indian hobby shop) for emax

or rcbharat for sky surfer

@Bunty: If you want to buy props you can find here http://www.kinetichobbies.com/index.php/accessories/propellers.html it costing just Rs.20 to 30. first figure out what kind of size prop you need.  Hats Off

And one more thing don't waste your money and time on experimenting, just buy RTF planes like easy star-2 or sky surfer.  Hats Off

Skysurfer is available at Rcbazar. It has all in it, like motor,esc,prop,servos. All you need is put your lipo, RX and fly.

Here is the link http://www.rcbazaar.com/products/1063-sky-surfer-v3-with-motor-esc-servos.aspx

Buy some good props like APC http://www.rcdhamaka.com/index.php?main_page=product_info&cPath=3_48_80&products_id=674&zenid=ouicd0rgvgaf9t4v1a78knnd34
and electric composite props http://www.rcdhamaka.com/index.php?main_page=product_info&cPath=3_48_80&products_id=1104&zenid=ouicd0rgvgaf9t4v1a78knnd34
(Links just for reference)

They will last long and can take much betting before giving up. Those orange color props breaks very easily if you are learning.

This figure is just to test the system not to use in airplane.



My avionic motor  uses 7.4 volt battery with 20 amp esc

Can I use 11.1 volt 2200 mah battery  with 20 amp esc

Will it be save  to run motor.


Motor details
PROP - 6x4
KV (rpm/v): 2400
300  gms Thrust
Power: 55W
Lipo - 2 cell 7.4V
ESC - 20 amp




in short i want to know can 11.2 volt battery be used in place of 7.4 volt battery
with the same esc ie 20 amp

recomended battery for motor is 7.4 volt

Tomorrow is Sunday new connector are missing prop is also missing but I want to bind up the setup

So I use electric switch board copper connection connector if you see in attachment
 And helicopter blade instead of props I will give very little power so as the motor do not burn up
battery is also having very small holes just like in charging point of battery i have big size battery connector.

Should I continue or stop and wait for new items to arrive

These items are available at kinetic hobby but it will take some time to reach to me.

I can test setup or I stop.
