Thanks guys!
Will post a short video as soon as I go the camp, right now am in the oil fields..will be home on Saturday.
It still has minor drifting issues, utilized all my free time building and setting her up so am kinda out of time for the moment.
@KALYANPRODHAN I do have bits and pieces of the build log, which I think I have posted in some thread before..will try finding that thread later.

Any vital pieces of info would be of great help..

Yea! one last thing, weight is 1.2Kgs and I get around 6 to 7 minutes on a brand new 2200 30C lipo, I wanted to know from experienced people, what if I use a 2650Mah 40C lipo? will things heat up on the same settings?
I am using a 11T pinion on a 2700 KV motor and everything is Ok, the motor gets a little hot around 60 Degrees,The ESC is plush 40, remains cold throughout flight.

So, for a guy like me who doesn't know much about helis, the question is, " Can I have a video of it in flight?";D

What are people's reactions when they see this?
not many people have seen it yet, but the ones who did don't believe when I say I built it.

If you post a few clearer shots of the rough edges where the fuselage was repaired and elaborate on the materials used, perhaps we could help smoothen out the ridges.
I will, soon.
The tail section is stuck using 2" masking tape + white adhesive + a little cyno.
I first used a wood filler to smoothen the rough edges, but as time passes, cracks are noticed>>not advisable on a model where vibration is the main problem.

This is the tail section which has been masked and glued, am also using a zip tie to diminish vibration and its working good.
Now the question is, how do I cover all this up without putting on extra weight?

Actually there are two more threads, I can merge them if you want; it would make a good log :)

Thanks a ton fellow member! yes you do that as I am going for inspections now!

I am assuming that the fuse is made out of fibreglass. In that case, would it help if the entire tail section is re coated with a fine layer and sanded down with fine grit?
Growing old is mandatory, growing up is optional!

Actually no! it is not fiberglass, it is white Styrene 8-)
I do have extra sheets of the same, but it is a bit difficult make it smooth as the thickness is 0.5mm.

A glimpse of what was happening today..

There is a mistake in the yellow "V" symbol can some one point out?
And an interesting question, does anyone know why the Israeli army had those signs on their helicopters?

AFAIK, the yellow "V" is painted on single colour/ green/sand yellow Israeli AF Helis as recog livery to prevent them from being shot down by friendly ground fire. The "V" is not used on the camo versions and therefore, is out of place on this model. Also, Since the CH 53 operates extensively above water, this marking would not be applicable on it. I could be wrong though......................

Isn't it  a marker for helicopters with flare dispensers.

Here is a video I shot at night, its too dark to notice anything.
The heli has a slight drift and I suppose I will start to work on it as soon as I get time.
I will try and upload a better video tomorrow.

Yesterday was rather a bad day when the tail gear slipped and came off, I tried searching for it but could not find. Replaced it with a new tail gear and after 2 flights found the lost gear stuck between the bottom wood support..
