Hi Guys !!!

Inspired by the design and after seeing the actual model fly (by Angad), I decided to make one for myself.
Wingspan 28 inches (approx)

Here is what I plan to install.

Battery: Turnigy 2200 mAh Nanotech 3 Cell Lipo
Receiver : Assan 6 channel Micro Receiver
Servos : 9 gram servo HXT900 X 2
Motor : Turnigy 2627 Brushless Outrunner 3800kv 260 Watts
ESC : Mystery 30Amps Brushless Speed Controller
Propellor : GWS 4540 or APC 5.5X4

I hope she will do good and look beautiful in the air.  ;)

Would appreciate any help on the coloring part  :salute:... (what color to use... dont have an airbrush... how to proceed etc) (THIS IS BIOFOAM)
Cheers !!!

{:)} {:)} {:)} Hey Saurabh, the color scheme looks great!! By when will it be ready for its first flight ??

saurabhhsrivastavaa

Thank you all for your compliments. I will try Fevicryl as suggested by Angad. Lets see how it turns out... :)

A nicely built jet Saurabh,
looks good and the electronics too seem to make it one hellva bullet! {:)} {:)}
Just one question, My mustang weighs approx 750~800gms with electronics, will a 100W outrunner and a 8x4 prop make her a good sport flyer?

Thank you all for all your inputs and compliments.  :)

Appreciate your time looking at the pics. Here are a few more that I clicked today morning.

Ashish, my apologies for not crediting your inputs. :) I have to compliment that you have been extremely supportive and helpful all this while. :D thank you very much.  :bow:

For the paint, I will try Fevicrly on some waste cutouts first. Since I do not have an airbrush, will see if the brush strokes are visible on the foam. If so, will try some other solution.





















Cheers !!!

Hi Saurabh,

I wanted to know how are u planning to use the motor that you have selected as the shaft in this motor is coming out the wrong side. Isn't it? Also please tell me the type of motor mount you would be using with this kind of motor.
Helis and Quads ROCK !!

A few more pics after painting.

Will be maidening her this Saturday. Will take the video and post. Any advices on characterstics of Jets ??? This is my first pusher jet. :D
























Cheers !!!

Looks mean and ready to bomb some one ;) :thumbsup:

I thought the thrust angle setup for pushers was different from tractors... tilted slightly upwards ?

Do glide tests work reliably on these FAST models, where stability depends quite a bit on forward speed ?
Hangar : Please see my introduction.

saurabhhsrivastavaa

Thanks Anwar. !!!

I am not sure of the glide test. But Ashish's Su47 has amazingly low stall speed (inspite of wing rocking) and does awesome alpha and cobras. I am expecting this model to fly smooth and steady. However, stability does depend on speed on such models (unless you have thrust vectoring) :)

Lets see how does she does on this saturday. Will post the results and hopefully the video as well.  ;D

I dont think I have taken into account the thrust angle to be a little up. Its exactly in centre and in the middle of the framework. Do you think its gonna make a lot of difference?

However, I need some info on the CG. Could not find much data on CG for this model. If anyone can help, it would be great. !!!  Will install the battery accordingly.

Cheers !!!

Hey!! this looks great yar!!!!

now u started to compete me in coloring!!!! just joking!!!!!!!

abt thrust angle, generally it should be little upwords, but in both of my fighters i didnt bother to have any angle, kept it inline with fuse only!!!

lets test it on Saturday!!!! going to be exiting!!!!!

i am also planing go for new SU37, with the help of Agand!!!!

sounds like screaming fighters going to dominate Airoli field!!!!

whoooooorm!!!!!!

Hi Saurabh,

Awsome Build..but had some questions

Which color and method did you use to paint your bird?
What motor are you planning to use on this bird as it doesn't look like the one you mentioned in the begining of the thread?

Hi Hellyflyer,

I have used Acrylic colors to paint. (Fevicryl) or Hobby Ideas from Pidilite. No thinner / additives added/required.
Done using normal paintbrush.

I changed the motor to 2212/6 2200kv brushless motor with 35/35 amps ESC. Got it from FBOTS. Will be using either a 2200mah 3 Cell 20C or a 1600mah 3cell Nanotech.
Cheers !!!
