yes you're right... chital told me otors will burn up if i'll go for 10"
weight should be more than 1.5kg

I'm facing some problems dealing with my quadcopter... it wants to dance not to fly...
as i'm a newbie to multirotors investing 15k with no results is my worst possible nightmare..
care to guide me?

can you post your config. and problem?

x config... problem is it cant lift itself and is stalling in one particular direction

roby
from your pics you posted above i see that you have not mounted props in correct order. second thing dont use cellotape. keep your setup neat and clean. mount your FC properly.

mounting props in correct order? what does that even mean?? and yes..i think my fc's little tilted.. in that case i'm required to do acc calibration again??

kk 2.1, scratch built frame, 1000kv outrunners, 25 amp turnigy plush escs 9X4.5 props

props on the same arm must be CW or CCW on your pic one prop look cw while other one is ccw on the same arm.

brought from quadkopters.com ... well there's sth serious cuz its extreamely unstable... can't lift the thing

check KK2.1 motor layout. make sure you have X mode loaded. it will show you which motor should rotote in which direction. once done mount props in that order. like below

m1    m2
cw    ccw
       X
m4     m3
ccw  cw

i dont know whats cw and ccw

Roby my friend, I don't know if I should feel sorry for you or chastise you. With your RC Skills reading a self professed "Intermediate", you have no right not to know the difference between CW and CCW.

Props that are designed to spin Clock Wise are CW, whilst those that spin Counter Clock Wise are CCW.

These pictures should be self explanatory. Look at the third picture closely. Notice the pitch of the props. Are your props mounted similarly?

well explained VC sir.

The above 2 comments doesn't go well together.

I have been seeing a lot of people recently deliberately telling that they did something when infact they never did.
Example: A customer of ours recently called about a Glow Plug Lighter and told me that it's not generating enough heat.
I asked him to use a voltmeter to check the voltage of the Cell that he is using.
He said had already checked it and found it to be 1.5 volts.

I asked him which cell was he using and he told that he was using a Rechargeable Cell which clearly is wrong since rechargeable AA cells usually doesn't go over 1.2 volts.
I guess people are getting more and more lazy

The video under Reply#11 does already cover up about CW and CCW props. But seems you didn't closely watched that video either.

Roby, The whole reason behind this frustration i'm afraid is anxiety. While we certainly can understand that anxiety will be there when you start on something new. But we also want you to understand that if you don't go step by step then everything will get more and more messed up which will create and increase this frustration.
I hope it makes sense.

And guys i suggested 9" props by purpose
Please calculate the thrust required to lift a quad and the thrust generated by these motors in 9" props
Please advise after calculating thrust specially to someone who is new to this
No offence.....
@roby
You need to have patience for this
You have to learn stuff
The quad will not fly until everything is set perfect and the best way would be meet someone locally

9X4.7 props on a regular quad 1000KV motor is fine.
It's just that since Roby is not going step by step, it's creating a lot of confusion.
Apart from that, he is not using the correct terms.

Example: Stall
He did mounted few props wrong way and in such case the quad can't even leave the ground.
But he referred to it as stall which means approaching ground (while the quad is in the air)

Well i know that but buy asking him what does he mean by stall all he would get is confused lol

oh well thanks vc sir, i got confused their,, i thought it comes in a way whr same colours lie opposite as in many quads.. it was not the case with this quad..

And for your kind information i'm an intermediate to planes not to quads.. visible right?

and Mr. indian hobby .. i mentioned that it stalled even before it left ground... no questions of falling

Very visible.

Do we hint a faint trace of sarcasm here? That would be quite unwarranted after your plaintive cry fro help 'plz plz plz....'

Being an intermediate in RC aircraft you will no doubt understand that Indian Hobby Shop was merely pointing out the difference between a 'STALL' and a model 'Not leaving the ground'.

Hmm, Well if that's how Plane intermediate flyer uses a term like Stall (a term which is so closely associated with planes) then All i can say is.. Sorry for not understanding "your language".
In the language that i'm familiar with (they call it English) Stalling means falling from air to ground and not from ground to ground  

BTW, They call me Bhavesh.
It's in my signature... visible right?

Mr. bhavesh....in your language what ever you call it... is happening again...even after fixing the props

The whole idea is that when you start to work on anything you should go step by step.
If you do get stuck, it's most likely because you were not going step by step.

What to do when you're stuck?
Try to rectify the issue by going step by step atleast this time.
But doing rectification as well in an unorganised manner will make things more and more complicated.

The video under Reply #11 (Which i personally shot) talks about the Props CW and CCW, Motor Rotation direction, Prop orientation and spinning Direction, Jerk Test and others. If the video would have been followed then the question about What is CW and CCW wouldn't have come in reply# 29. Instead it should have came as reply #12.

Sarcasm, It's everywhere.

i thought cw or cww was some specification of prop... well stop pointing out
rather you can help me to finish this quad.. define your step by step that'll help others as well
Maybe i'm nowhere as compared to you , you got brains... does that charges you to make fun of others?
