After so many flights with Camera etc, few points emerged.

(1) Consider fixing wings permanently, there is a danger of it coming off in the air

(2) 2805 came back on with rewound motor (9 Turn per pole, Thanks to Sandy and his electrical Engineering mind)

(3) be careful of down Thrust , adjust thrust line properly.

(4) 2805 5x3 prop is the best combo. with a 2s Batt ( For you Divyam), can use 3s at your own risk of course, Key is get airborne and climb with 70% power and fly at 50- 40 5 power with 3s

i haven't taken a flight yet ,thinking of a maiden this week end if weather permits also what about the canopy cover any suggestions ..me gonna paint the shikra metallic black with some detailed graffiti on them , let the kites/crows have a electronic lookalike  to chase  ;D

servo on the boom ??? you will require more nose weight as it is with 2s she requires some nose weight

At last I got to load some random pics of my Shikra, With custom (pepsi bottle)  ;) canopy.

With some 'Red white and Blue' masking tape coloring scheme (missed picking up some paint... beside I don't have the brush talent like Gusty and Sandy)  :giggle:

Put some fishing lead as weight for CG at about 51mm from LE, Gusty thanks for help with my DX7 (DR and Expo)!!!

All the electronics from rcforallin. (Sai thanks for sending in Carbon fiber rods that got lost in transit)

Had few 'interesting' flights whenever I found some time...

super joe, as good as you music skills, :thumbsup: i still feel you can re-route the esc properly , also blow some hot air :giggle: over those tapes, it will stretch and sit nicely

PS
painting skills is all sandy, i am a flier ;)

Cool canopy  :thumbsup:

Could have used sprite/ thumpsup instead of pepsi. comes out more nice.  :)

FlyJoe

Sprite will give it one more color too... will try and update.

I had a cart wheel at the last landing and the fuse gave way right at the spot where the carbon fiber rod finishes...

So took it apart, used this as the best opportunity to put the Esc inside, I cut a channel for the motor wires, tucked the Esc inside.
Then took a piece of Lead from my fishing box... Hot glued it to the fiber rod... made a similar hole on the other side... hotglued this and used Cyno for the rest of the Fuse....

Sandy, I got a green, smaller canopy...

Gusty, Hot air did good... lol!

Currently, we are heavily practicing on FMS sim. I am realizing how important to practice on sim. Lest each flight would cost me a new plane.

I have done the necessary solders of Motors and ESCs with 4mm gold connectors. Where can I get following motor mount?? I dont want to experiment much.

1. Which glue should I be using for Shikra?? I have read about cyano in this thread. Can I use Quickfix which is available in local stationary shop?? Any specific tips for glueing of Shikra??

2. Generally, I have seen, ailerons are controlled by a silgle servo. But in shikra, there is a seperate slot for servo on each wing. How to control both servos with a single channel? I have HK-T6A V2.

My questions may be very elementary but it is my fault that I can not dedicate enough time on the forum.

Regards

rcpilotacro

standard CA would do, dont use Quickfix, it eats foams slowly  ;D


for aileron use a 'Y' Cable, thereby connecting both servos to the 'Y' and the common end of the 'Y' goes into your aileron channel

Got the motor mount and Y cable from rcforall. I have everything except battery and Glue. I have already put an order to HK for the batt.

Dear Mr. Sai and all others,

The motor mount- as far as I can make out -is of slow stick. I have another problem. :headscratch: This does not fit on the plane. How to go about it?? any directions?? :help: :help:

I am little confused about glue. :headscratch: :headscratch: Augustine has mentioned about standard cyano. What is the brand name of  "standard cyano"?? How much minimum I should have??  :-\

Regards

rcpilotacro

you need to cut and file the mount or , read this thread in the earlier portions you will see some mod done for the mount, it is a pusher config so mount is not as crtical but the motor must be mounted flat on the mount for the thrust line,  CA(Cyno) you will find it in any hardware store for your info in mumbai these are the manufacturers, there is tele nos included call them first (http://www.grotal.com/Mumbai/Cyanoacrylate-Adhesive-Manufacturers-C45/)

i hope it answers your questions
