RC India

Hello guys, today i completed with my first quad built, i have assembled Frame+motor+Esc  :thumbsup: yet to mount APM 2.5 FC

I have used Hobbyking X525 Frame
Dt700 Brushless motor
25A Plush ESC

Soon il upload setup/installation of APM 2.5 Board on youtube  :)

The quad is looking very beutiful. what  size of props u have used.

one more question , to all forum members .
Flying quad is easy or hard compared to planes ??

PS: sorry deepak using your platform for my stupid questions. 8-)

No problem  ;D And about quad, this is my first build  :giggle:  i have never flown anything before  ;D  so why i chose quad is, am doing this as my final yr engg project so that later on i can modify for my hobby  :giggle: and moreover am using this for FPV, quad will have better stabilized video.  

Prop size is 11x47

Please mount the propellers much closer, as close as possible to the motor can to eliminate vibrations. I would suggest you use a prop adapter after cutting off the excess motor shaft.

@sundaram, yes sir, already a screw got loosened when i was testing the quad. but as of now the vibrations hasn't caused much trouble. nd thank you sir, cutting of the excess shaft is a good idea, definitely il hit the ground and bend the shaft

AWESOME !!!

Thank you  :hatsoff:

Deepak, My advice is to you is Cut the shaft and keep it short.  These long shafts seem to bend soon and it's going to cause a lot of vibrations.  If you cant do it yourself take it to a workshop and get it cut professionally.  Remember to encase the motor using some tape or cloth before you do this.  Small metal splinters can get into the motor and get stuck to the magnets. Then you'll have to open up the bell to clean it.  This is'nt difficult though.
I have replaced the shafts with 6 cm.  Everytime you crash the shafts take an impact and bend.  Even a 1-2mm bend is enough to give you a ton of vibs.  Happy Tweaking and flying.

@dreamfly, sir, i have cut the shaft as suggested by you and sundaram sir, am using some locktite solution for the screws, as they are getting loosened due to friction, moreover some rubber washer for motor will greatly improve damping i guess, thank you sir, for valuable comments  :hatsoff:

use thread locker instead  or better why don't you use nyloc nuts?

Hey deepak, where did you get Locktite from?

locktite should be available in any hardware/paint shop.

Thanks, but I couldn't find it anywhere here in Kolkata. Is there any special local name for it?

Locktite is American.  Does it have to do with the ruling political party in Kolkata I wonder? Also hobby shops stock it.

@mhkabir98, hello, i got that from local hardware shop, its thread locker Anabond 122, it costs Rs 20 for 4ml, which is more than enough for my quad

@dreamfly, i searched for nylon  nuts, its not availavle here in cbe. So using thread locker instead  :(

Not Nylon nuts  but  "Nyloc".  These are normal steel / stainless steel nuts with a sealed nylon washer.

Thankyou sir, il try that

yesterday I flew my quad after a serious crash but luckly on my rooftop.  I then flashed my F-30 esc's and here's me testing the bird once again.  I am very nervous these days and very cautious fly flying.  I don't take it too high until I am sure that the motor esc combination works. I use Tiger 3506 motors with 12x38 props with Simonized f-30 Esc's. You can also here my son asking me not to take it up too high. He witnessed the crash earlier.

Nice work deepak, looking good...

Man you lost it?  ??? ??? ??? ??? ???

No. I found it, nearly 1km far, i pulled the throttle down totally nd it fell from 60 meters height. Luckily nothing happened except for a broken propeller

You are really really lucky...  8-) 8-)
 Dont take it that high fly low and learn  :) :)

Agree with what Arun said. BTW what with the upside down video? :headscratch: :headscratch:

Yeah. I neva took high  :headscratch: its the wind and moreover i forgot about the orientation of quadcopter   :giggle:  tats wer the problm starts, only after it took off i came to know abt it.  :banghead: messed upwith the control  :-\ .. And the video ? Its my friend who took in mobile  :giggle:

Hello, here is my test flight of APM 2.5 and it is stable  :) i'll add videos of fully autonomous mission soon  :thumbsup:

nice, if you can cut down the long shafts of DT750. Sometimes they give lots of vibration.

Looks good, fly it outside dude.

@satya : hav to cut, as far as now, its good, even after crashing.

@rahul  : i have already did fully autonomous mission today. wil upload it soon

i am waiting :D
how stable is it?

@deepakkshr, where did you buy the APM 2.5 from? Indian Source? Also, how much did you pay for it? any links?
Cheers!

www.rctimer.com.
Its arduflyer 2.5

@Rahul : First few flights wer difficult for me to control as i have to constantly adjust the throttle.  :-\ I simply switch to altitude hold mode, so i never have to worry about throttle, it stays in the same height. Its real fun. And also the automatic mode, it takes off on its own, goes to all the way point and land on its own  :thumbsup:

@veloci: I got it from rctimer.com. I paid around 6700 -6900 with gps

and telemetry?
how did you manage customs?

I hav no telemetry attached to it. Nd luckily no customs
