woah... that is very neat! are you using a pusher prop? or a standard prop put reversed? does it really make a difference?
waise... dont you think, the "belly" of your model resembles a raptor than a pak-fa. The twin engine PAK-FA has two separate intakes with a channel in between resembling a Sukhoi-30, whereas the raptor has an internal bay in that region. With a similar planform this is what i feel really would differentiate between the two.

i am using normal prop, with motor mounted backwards, and rotation is in opposite direction, so it will be normal prop in Pusher config!!!! it hardly make difference if u use pusher prop or normal prop with changing motor rotation!!!!!

abt belly, like most of my earlier builds, and different design studied on internet, i prefer to keep design simple, instead of making it complicated, also u get plenty of room for electronics...

I agree, but some people speculate that it makes a difference.Logically, I feel it shouldnt make a difference, thanks for confirming.

Although i would like to point out that this in not the case with brushed motors. They can have different speeds in opposite directions.

Active control tech(ACT) provides for directional stab on Pak fa. In an rc without fin will be an issue even with gyro. Take care of this aspect. Ther are alternatives . Can Be discussed

Hi gusty sir!!!! ACT, no i m really not aware of it !!!!

but will it affect RC plane!!!!! Abt vertical fins, yes i will put them but it will come in the end, bcoz it is very easy to store and handle while building plane without rudder/fin. it will be mostly non moving!!!! will see how it behaves in high alpha, if i found that nose is falling then will try to put some rudder control with gyro also!!!!

pls advice!!!!!

Ashish

Fin is for directional stab i.e so that she doesn't depart directionally. Nose drop is essentially longitudinal stability issues. Low chord fin will make the airplane depart at even at slight high alpha. Consider two ventral fins as well. Short chords will do. Ventral fins aren't masked at high alpha.. Believe me you can show off a small dorsal fin and yet have good stability. No gyros required. Submitted for consideration

agustinev,

talk sense man!!!! by that I mean talk in a language that a dummy like me can understand
ACT , two short ventral fins etc.... D-UH What?

@ Pankaj!!!!

ventral fins are pair of small vertical stabilizers beneath the fuselage. acts as stabilizers only!!!! during high alpha maneuver rudder is covered by wing and is not much effective, so to provide stability these fins are very useful!!!!
otherwise directional controls become very difficult. without which nose tends to fall down....

@gusty,

i havnt planned for ventral fins but, lets see how my maiden goes, depending on that may add some. little worried abt how my maiden with TV goes  ....not sure if i will be able to handle or not  ....
more over to secure belly while landing i have already put skids protruding beneath fuse, close to rudder, it may work as fins as well.... will post pics soon... it is abt to complete 

already attached elevators, need to connect push rod and rudder and fix location for battery and it will be ready for maiden...... but i think will be able to maiden only after rainy...

here is the color scheme i have decide, it is almost similar to original, but symmetrical....

give ur comments guys!!!!


cheers
Ashish

Differentiate under And over wing color scheme.
Pankaj
ACT is no big deal to understand. Search will give you plethora of hits . Fly by wire fly by light auto pilot auto stabilizers are some of the examples of ACT

yes sir!!!!! this is from top, bottom will have single dark color, may be dark gray or Black!!!!!

finally, with lots of patience, was able to put some colours on this one.

took few evenings and lots of patience, and Acrylic colours... vertical stabilizers/rudders  are yet to be attached

initially decided to use spray cans but, found that it is not feasible as i needed few shades, more over if not used properly may damage foam....but would have been easiest ways to paint this bird.......

but finally decided to use acrylic colour...... Gray, Black & white....

it is still not in final state...require few last strokes of white and outlines....

though it took lots of efforts, at some places brush strokes are visible, i tried to make it smooth.. but ....some places...

but overall it looks beautiful!!!!!  started to love this bird more and more.... little afraid to maiden this

cheers
Ashish

 
Looks good man!!!!

Ash
Where is the fin? Won't she spiral out ?

Gusty

Check post #36. He says they are still to be attached!

Wow nice build, great color scheme looks great, cant wait to see the complete build

would be interested to see how you'd fix the v-stab/rud

Good luck on the maiden flight...

Cheers,
Arun

awesome build ashish... have a nice flight...

thanks guys!!!!

soon will be attaching fin, i will be simply stick it on the wing using Evotite and it will be firm!!!!

i hav don this in some of my earlier builds.

after lots of efforts in painting, finally i finished it!!!! 

it look beautiful..... may be i spend more efforts painting rather than building it  ..... need lots of patience  ......... few wrong strokes and u have to correct those  ......

so here is my one of the best build......

some more pics from sides

My son playing with motor!!!

The best picture of the among is that two best creation of you side by side.

Your Plane and your Son.

Really looking nice. You should get a Salute from me to allow to play children with the plane. The broad forehead of your son proves that you are really good in creation and beautify them with long patience.

Enjoy the creations.

That looks cool.Waiting for a video.

thanks Kalyan and Foamy!!!

Kalyan thats is really interesting!!!!! and my son likes to rotate that prop so i am little less worried.... took the pic and took my plane away from him

cheers
Ashish

awesome build!
