Title: first attempt

Hi everybody

this is my first attempt, built with 4mm coro under camber airfoil 38" wing and 29" fuselage with 2 aileron servo and 1 elevator servo, emax 2822 combo and turnigy 2200 mah battery with everything weight is 700 gram, just heavy than my calculation, when we reach to beach for first test i forgot the elevator servo extension cable at home, and also it was just windy day yet with pre adjustment of elevator I railsed tx's stick and at half throttel it left ground and suddenly I took my fingure back and again it was on ground I did not take more chance because water of sea was very near, so for another attempt I am waiting for calm day and less water on beach, first I planed for elevator and rudder control but later I used ailron control, so  alilron controls are near to fuselage and I have doubt wether it will work or not. I am new to this hobby, experts are requseted to correct my mistakes.

I think the fuse is made up of the plastic strip that is used to cover the wiring in houses. Am I right Kasta Sir

Nice build, but I assume that your ailerons would not give you good response as they are inboard and towards the wing root. You may do well to either extend them to full span or move them out towards the tips

@flyingboxcar,
I assume that the low response of the aileron would be helpful to a newbie and work more as a flaperon.

The "low" might better translate as "almost no" aileron control. If you wan't/need less sensitivity, reduce the throws or add expo/dual rate if your radio supports it. Do remember that a certain minimum  control is required to recover from some situations.

In short, DO follow Captain's advice.

Thanks for response
Vivek kumar is right, the fuselage is of the plastick strip which we use in our home to cover up viring and it is easily available everywhere. and also for motor mount the albo which is used in the same plastick strip and it is verywell fitted in the fuselage with just 3 screws , though only plastick strip will bend easily so i have put 7" light wooden stick inside the strip to prevent bend, the whole model I prepared only with a cutter, and screwdriver and some local tools which are always awailable at home, if all materials are awailable we can prepare such model within 2 to 3 hours. there is also landig gear which can not be seen from the back side  the ailerons are near to fuselage, only to prevent quick response, because in real life I fly first time, though on pc I have good command  on gamepad, I have used realflight 4 for practice, tommorow I put more pict.

please forgive my language mistakes I am not so good in English

FYI "flaperons" are ailerons doubling as flaps, and not vice-versa.
