will it works..?  yes..see the video..

Modelers, now we made a working turret. You can take more time to make a turret according to plan. So, now we can think about a turret with azhimuth elevation of a gun barrel. For our first turret, we took one channel of TX, and all you saw that we can use any channel to control it; and easy.
So, here we need two channel, one for rotation and one for barrel control.

So we can use any TX controls but you can use the right side TX controls for turret control, while the left for prop and direction.

to make a proposed turret we need one sero set up as earlier, and one more micro servo..
place a micro servo, on a foam board, leaving some margin all around..

place and check the servo slot..place the servo from in to out..

now draw a circle with compass as shown..
draw a second one also..

cut out 4 identical pieces..and fix the servo with a piece of foam bord, thus avoids the glue or screw..

start to fix side pieces..
cut out the second circle, and make a drum with paper strips..

glue the drum in servo cam..
build the balance..

make a barrel according to plan.
here i made the barrel from a straw.
paint with appropriate color.

time to fix..and check..

how it works. See the cool video here...




Friends, all given ideas are mere keys. You can add any imagination to your turrets or all in to scale. All we know how much time we spent on our models, that much be the finishing, and detailing of our models. See how simple it is to add a working turrets to our crafts. You can also add a gun sound with a simple electronic circuits, have some nice crafts. 

Friends,
I got some mail, asking about to extend a servo lead, for turret use. Answering them all individually is tough job, so i am adding here.
Its all simple once again. Usually all we go to buy a servo lead extension, for our use. It is very easy to extend a servo lead, and can extend up to 4 meters, as i worked many with my rail road switching points, and works well..but avoid using low quality wires for this purpose. As the low quality wires can make a good resistance in the path of electrons to the servo, thus the performance is decreased.

So how to extend servo lead, ok, its all simple..

=> take a servo, may be any..micro / heavy / standard with you.
=> cut the leads on half.

we can purchase the flat ribbon cables in various colors and densities, so, buy a meter of flat ribbon cable, while keeping the wire color codes of servo leads, in mind, and please do not buy too cheaper wires, but at least in 20: 20 density.
here one meter wire costs RS 20/-

then peel of three wires from flat cables all in to same color codes to servo wire..

=> collect some heat shrink tube from any electronic spares shop, in to 3 or 4 mm.
=> its cheap, and costs 20 Rs/- for a meter.
=> we can also use insulation tapes.

peel out the insulation from wires.

=> insert the sliced heat shrink tube on to wires about in to the lengths of 1 inch
=> solder all wire tips with a soldering iron
=> make sure the soldering iron is truly Earthed.
=> if not, you can remove the plug, from wall socket, to avoid any high current leakage from iron.
=> this current can damage the micro chip of the servo.       
               take care.

now, after bright solder, pull in tube, to the joints, and heat the tubes with the crest of the soldering iron, you do not need to buy a heating gun for this.

=> now make sure the wires are ok.
=> look for any protutions.
=> now the servo is ready for the show.

hi roopeshkrishna
hello mate, Yes I am still about in the back ground, watching your excellent builds.......
this is a really good tutorial and very useful for those who want 'even more' realism in their models.
well done , very easy to follow steps.  

regards
don

yes Sir..all are simple..

Always wanted to make a continuous rotating servo, this is a very good tutorial to do so. I have seen some other tutorials where the pot is replaced with 2.2k resistor, don't know what difference it makes.
