I have plans for 700 heli if any one wants to build a big heli contact me.Plans are drawn in Autocad 2013
this pic is portion of it other things ( head and tail assembly) in other file Everything is of required dimension and size
Details
Total length 1350mm without blades
        height 420mm

frame height 260mm
         length 370mm
         2mm thick
Battery Compartment 60mmx70mmx365mm

Required 
Servo : standard
              specs: 10to 15kgcm torque speed (60degree rotation)=.10 to .08
             Tail servo
             specs: 4to 5kgcm torque speed (60degree rotation)=.06 to .04
Motor 520kv power >3000w

Plan include every thing required for heli 

So after getting the plans how do we build the heli do we need to fabricate the parts

You need a CNC 5 axis or  4  axis  to cut them on alloy  Aluminum 6061-T6 and assemble them with other things like shafts bearing and nut bolts dimensions included in plan And some carbon fiber parts and frame  dimensions included in plan

thanks for all this. Iam out as I currently don't have an acsess to an cnc machine of 4 or 5 axis.
btw can we use a 3 axis machine for this one
super good initiative

you can rent a CNC will cost you around  :Rs:300 per hour  if any one interested

Who has drawn the plans? And i dont see the side frames in your photos?

You can not see side frames because they are drawn on paper

And i have drawn them

How much will it cost if I ask you to get the whole kit cut and everything including shipping to chennai

I have no idea

Wait till I get my own done

oh so you have not tried and tested it no prob will surely wait

@abhay i have sent a PM go through that carefully.

It can be incredibly dangerous to fly such a large chopper that is untested and a brand new design, you sent a pm stating your head design is better than DFC, Please understand DFC is a tried and tested system. With many hours of testing behind it.

I am telling this for everyones safety.  I would advice you to contact some other members of the forum who are much more skilled than me like Gusty ji or Anwar Ji for advice on whether you should go forward with it or not.

Pls. Dont be demoralised by what i say. I am saying it for the benefit of everyone. And for your own personal safety. Because large helis can be incredibly dangerous.

Regards

I second you, yashodhanp.

abhayf14, what other models or design information did you refer to before laying out your own CAD? Have you done the necessary software/theoritical analysis for ensuring technical parameters are within tolerances? If yes, please post those details.

Also, please email me the deisgns I'd like it in .dfx format.

dude have you heard of the print screen button?

i am not that tech savvy !!! but i have seen it on kbd dont know to use it

Press print screen button on the keyboard > open an image editor like paint or photoshop > paste > save.

tech savvy? so you have experience with helis, and can make a cad drawing, but you can't print screen? enjoy your 700 heli.. if you hurt yourself, don't come crying.. we've already warned you...

aniket bro no offense but recently u acting like a grandpapi of the forum ...man chill and calm down am sure the guy has an idea and knows what he has done and knows the risk factor involved too ....all heli guys do know ....its a plan that he envisioned and chalked it down ....when the build starts he will take the necessary precautions to ensure safety  and make sure good materials are used ....any way i would love to c the complete design if u could pm it to me ill have a look and give u inputs abhay ...cause i was thinking of the very same but dint find time .....pm me ur plans ill have a look and help u with it ....u dont need to build it urself ...once we conclude the design is rigid and great, u urself can approach a heli manufacturer and get one done .....may be a new heli in the market

Lol nitesh you really want to buy a 700 with no experience of building heli's? or no experience of even flying one? a 700 kit itself comes at Rs.50000+. Bro think before you decide what you want to do.

hahaha! yea I guess I've been getting quite over the top nowadays! I sound like some creepy old guy sitting on the side and yelling at others...

my concern is only that someone who knows autoCAD and can design a heliframe doesn't know of the print screen button? then says that he's not tech savvy... kuch gadbad lagta hai...

yeah dude ull scare the guy before  he even  finishes ....chill one step a the time ...yes its very common for people not to know or remember simple things even if they know complex things ....it happens to me ...may happen to u  also its not gadbad ....

no man.. I have been getting a little wary of super-sized rc choppers... ( the whole "large spinning blades that can slice humans" idea doesn't really appeal to me... ) since recently, courtesy the news... so it kinda freaked me out when this guy turns up saying that he's gonna scratch build one...

@abhayf14 unless you send your drawings to us , there is no way we can comment or help you out

for safety i am going too a true size 500 heli it may take 1 to 2 weeks
thanks all
