Gold connectors r used to connect ur motor and esc..If u don't wish to use gold connectors, u can directly solder motor with esc..

1. Gold connectors are used mostly to connect esc to the motor. You may buy them with the heat shrink tubes and connect your motor to the esc or you may directly solder the wires of the esc to the motor(or just twist them around in a DNA type helical shape like the guys at the local electric shops do.)
2. What extension cables are you talking about. Servo extension? Well that depends upon the relative distance between the servo and the receiver, the servo wires should be long enough or extended so that they can reach the receiver after having placed the servo and the receiver in the desired place.
3.Get the 3.17mm prop adapter for the Emax motor, here's one that is selling it http://rcelectro.com/index.php?page=shop.product_details&flypage=flypage.pbv.v5.tpl&product_id=62&category_id=8&option=com_virtuemart&Itemid=8&vmcchk=1&Itemid=8.
4.Well, the prop hole is always bigger than the diameter of the shaft and it makes no difference coz you are not supposed to glue the prop on the shaft directly. First tighten the prop adapter to the shaft with the screws and then attach the propeller to the prop adapter using the rubber bands. I hope you know how to attach the prop using the prop adapter to the motor.

Another thing is that you will also need a battery and a battery charger. BTW is this your first build? You should have sanded the wing to give it an airfoil shape.

Surya,

First things first, you don't need gold connector, in some of my motors i am using pins salvaged out of a 50 pin connector of a heavy machinery, contact has to be good, resistance has to be low that is the key, if you have a gold pin connector it is good, but for the aircraft picture appended above ? not necessary.

Your prop must have come with a few rings put the one that will fit into the prop saver protrusion, you can see the reverse side of the prop adapter that side may have a bigger protrusion, if it is loose it may precess and damage your motor bearings

Just out of curiosity, what is that thing you have stuck it with a cello tape on your wings ? do you think it will strengthen the wing ?. you need to read about various stresses on the aircraft and rigidity required.

Torsional Rigidity, Flexural rigidity , flutter etc. In fact Flutter is a subject, in which, if you want to understand  just the basics, will take you a week, these are some subjects you need to read, Don't mind my saying so, as i mean well for you, any help at all please pm me, those sticks on the wings is just  some added weight, Honestly to me it appears to be a model constructed in some tearing hurry, please spend some time, work on it more. Aeromodelling is all about patience.

Finally, you will realize over time, this forum is quite a helpful forum, HELP x 3 is not required, see topic of 'shouting' flagged by the forum admin in the intro thread.

Happy Flying :thumbsup:

Those things on the wing i guess those were pop sticks as per design given in mickeysrc plan. I wonder what is that material? Is it foam board?

viraj

Thanks a lot everyone .. Atleast now I am out of confussion..

your suggestions were really helpful.. :bow:


@ rohit : those are Barbeque sticks to strengthen the wings as per Mickey's Rc Video.

I am alomost done with the plane now.. only thing I am waiting for Tx & Rx.

viraj I have built mickeys FPV plane
I can tell you one thing about his models, make sure you have the CG  exactly or before the point marked in the planes. Otherwise you will issues like the plane is always pointing upwards.
