All dressed up and nowhere to go 

Since my TX battery is busted, I can't tune / test her. She just sits there trying to look pretty.

Dt 700 motors
10X4.5 props
20 A Simon K flashed ESCs (Thanks Pravesh)
KK2.0 board with 1.6 firmware
2 x 2200mAh 3S LiPo
Aluminium arms and ply centres
AUW 1750 grams.

Sick and tired of researching the ideal gain settings. Would the more experienced fliers care to guide me and let me have a set of 'failsafe' sort of settings for the board?

Thanks.

No joy? Where are all the multi rotor guys? Hibernating? I just came out of that.

VC Sir,
from what I have seen of my quad, the default PI settings are good enough for a decent flight. I had found that the self level gains were too high causing oscillations (I think the default was close to 70). Keeping the firmware up to date has been very important for me. I had some odd flipping issues with the old 1.9S1 firmware. I noticed that you are running 1.6. Steveis 1.19S1 is currently out.

Thanks, that is what I'd thought - the default settings were good enough. Since I have already messed up my settings, where can I get the default settings from? Do I do a factory reset on the board?

Yes sir, a factory reset will restore the default PI values. May I suggest you update the kk firmware. It can be done very easily with a USBASP tool or with a little more effort using an Arduino. The latest firmware is available here along with detailed manuals: http://www.rcgroups.com/forums/member.php?u=367321

Will this help get your Tx up and running?
As a temporary solution?
Can send.

KK Iyer Sir what are the dimensions of this tray?

Whether it fits or not, I am grateful to you for the gracious offer.

V2Eagle has already despatched one such tray to me. I am anxiously waiting for it.

VC - long time.

As I have a lot of time on my hands these days - I can make you a new tx pack completely soldered/heatshrunk with the choice of connector.

Complementary!

post a pic of your requirement and connector and expect a new one with a week complete with uniformed messenger.


is it a 6 cell triangular arrangement (7.2 volt)??

@VC,
3x3x11cm. Jst connector.

Didn't know Saikat sir too had retired 

8 cell 12volt arrangement

I had one such situation, but er9x firmware saved my day.
hacked the 3S lipo and made it 2S. changed the low voltage alarm cutoff to 7.4. voila, its done.
I dont remember stock firmware having such options.

Saikat and al the others - Thanks.

I was using this Lipo and the dimensions (LXBXH) are mentioned as 97X30X27 mm.

Saikat, thanks for the gracious offer, however, I wouldn't like to take anything more for free. Will accept only if I am allowed to pay for the batteries.

Warm regards.

VC - that is just a 3s lipo - use any lipo (3s) that you have lying around.

you can even get 3 cellphone batteries (bl-5c is a common one) and solder them
in series (bl5c) in my neck of the woods costs about 80/- a piece, so you
can have a brand new battery(albeit 900mah) for rs 240/- and some time with a soldering iron.

@SK, the KK board VC sir is using is KK2.0, and v1.6 is it's latest f/w .
@ VC sir, Do a factory reset on KK board, and all gain values are reset   load the motor layout again , Calibrate accelerometer, set up receiver channels and you are ready to be in air .
For your Transmitter battery, The above Idea by saikat sir is quickest, easiest and reliable, I used such a Battery pack (Nokia BL-4c x 3) on my FS-T6 for around 2 months (Recently upgraded to a Tx LiPo pack as Mr. Praveen Jose sir gave me one)

Hey thanks all. Had another 3S Tx battery 1450mAh lying around. Taped it to the body of the Tx and cut a slot on the battery bay hatch to let the wire in. All systems go.

Oh wow VC, your absence in the quad world was missed.
Good going on the multirotor, but may I ask why a hexa and not a quad? personal preference or for the rush of it?
Secondly, my question may sound stupid, but is it OK to run motors with prop savers on quads? won't the sudden changes in elevator/aileron affect the angles on the props? like kinda "wobble"
I am so happily flying my qrx350 pro, Had no time for building one!!

Many people use Propsavers on quads with out any wobble or any other problem...
It is a misconception that prop savers aren't suitable for Multirotors...
But always check those Rubber bands or O rings before each flight

Dear Dorwin,

The Quad was accomplished more than 2 years ago. It has now been stripped and the components are being fitted on to a sturdier airframe. The Quad has Prop Adapters. I was a bit sceptical about using prop savers on the Hexa, let's wait and see.

Cheers!

I never build my own maybe that's why I was assuming, but thanks for clearing things out!!

Awaiting a beautiful video VC..

Another question I had was about the arms, Is it advisable to let the arms of a multirotor rise up to a certain degree for it to be more stable?
I've noticed mutlirotors with arms on the same plane are more agile and sensitive to stick movements then the ones with their arms raised a little, is this theory correct?
Your answers BTW are all going to my next build bag!!

and VC apologies, I am bombarding your thread, but then again, your flowery thread is attracting a lot of bees!! and where else could I get my questions answered so fast...

Now that is something that I would like to know more about.

Well Hey sir that hexacopter looks really good sir.Waiting for the video.
Regards,
Aman.

A simple experiment, 2 pieces of A4 pepers. one coned and the other left as it is. The coned one will tend to fall in a much controlled manner as its pushing the air to its sides, whereas the plain piece of paper will be all over the place..food for thought!! Sherlok Holmes:hatsoff:
