RC India

Hi all,

I have designed a foamy Yak 55. I will start building the model & will share with you my progress till the flight... ;D the plane is designed slightly bigger than the normal foamies it has wingspan of 38 inches.. i wanted slightly bigger as its easy to fly outdoors in wind.

Sharlock

good one!!!! what is the motor ur planning to use!!!!????

The motor is brushless Chinese make http://www.unitedhobbies.com/hobbyking/store/uh_viewItem.asp?idProduct=4915
battery is 1300 lipo
prop 10x4
radio JR

The fuselage almost done.

Coming up nicely :thumbsup:

What glue are you using ?  And what is the thickness of the foam ?  Planning for any reinforcements ?

The glue is our great Indian glue "Fevicol" great for this job & better than the expensive foam safe that i have used in the past. The foam is 6mm thick, I will be using carbon fiber rod for reinforcements in the wing.

Plain old white color Fevicol used for wood work etc ?  Fevicol has many many types now, hence the question.

I use the Fevicol "MR" white adhesive works the best...

some more updates

Wings & tails feathers before joining. I need to bevel the control surface end so i can get the max throw for 3D flying.

For the paint scheme for this plane i am planning to go for red & yellow with black chex.. on the wing tips

Here is the wing attached & reinforced with a 2mm carbon fiber rod this will be enough to strengthen the wing.

It appears that the motor is way too small for this size. I recommend you put this.

and a 8040 GWS prop.

I will be experimenting with different motors. Lets see how it performs

here is the trim scheme for the plane before painting. I will start the painting the model with black chex on the nose & the wing tips

Finally painted mostly complete, only tail plane & bottom of the plane needs to be painted. I made a mistake by making a slot for the rudder servo in the very front of the fuselage actually i was planning to use a pull-pull system but later changes my mind. I will install the rudder servo in a normal push rod style near the tail.

Nicely done !!  {:)}  {:)}  {:)}

Thanks..  ;D  more to come after i install all the gear.

Hey,

What colors are you using to paint this as it doesn't look that it's being airbrushed

Thanks
Hellyflyer

I used fevicryl acrylic paint to paint this model. I have a airbrush but did not use it.

Cool I am planning to use the same on my Coro Build 3d plane.  :)

The acrylic color should work fine on your coro best results will be if you airbrush it, as the paint is thick & leaves brush marks on it.

Brushless motor installed.

Almost all done painted the bottom & tail plane parts.

Good One. Nice Color Scheme... Is this Fevicryl ? with normal paint brush?

It looks that the motor is a bit small for this. You may be able to fly it, but I dont think it would be good for 3D. Post the updates.

Lets see how it flies I have other motors also will try that if needed. I will fly precession aerobatics on this plane & later 3D..

like the build. Can you please throw some light on the colors used and the methodology?

The colors used for this model is Fevicryl "Acrylic". I used brush to paint this model. Before i start painting i drew the design scheme on the model with a marker & then started the paint process, see the model before painting you will see the markings on it. The time consuming part is painting chex.. but in the end the model looks great with the chex

Once you have the markings done on the model the paint job becomes very easy. I have a spray pen will use it on the next models i will build... I have many different crazy looking paint schemes in my mind. Hope this helps. ;D

Indeed a neat job done. !!!  :thumbsup:

Thanks for the information. Did you use the masking tape for the chex ?

Thanks..

No masking tapes used for the chex. I first paint the yellow & later the black using the guide lines drawn before paint but requires patience for this job

You must be having a very steady hand.......the plane looks really good.....where in mumbai do you fly??

Thanks & yes right you need a steady hand for this job a mistake will ruin the look.

some time back i used to fly at Mahalakshmi but thats far & to fly a foamy all you need is a park. We have a ground near by my place at Andheri were i mostly fly.

I am waiting for the servos to come... once i get it i will test fly the model.

Hey Sharlock

Which ground are you talking about..i live in Andheri too..may be we can catch up some time :)

Regards

Andheri  :o

Where in Andheri dude ? I am in Andheri East (Shere Punjab) too.

There is a small ground near Lokhandwala were i fly, not a big ground but i can fly a foamy there, sorry but outsiders are not allowed its a society play ground.  There are hardly any fields left to fly a rc planes

nicly build!!! Beautiful color scheme as well!!!! seems like ur really good in painting!!!!!

waiting for maiden video!!!!

Thats a great idea. We all must meet up to fly, will keep you updated on my Yak 55

great  :thumbsup:

Hi Ankur, Sharlock.

Its great to knw fellow modellers live closeby. :D

Thanks for the invite. would surely love to join you guys.
Ankur, where do you put up? are you at Andheri too?

And which 2 grounds are you talking about? is it close to andheri?

unfortunately, I am travelling for this week and may not be able to join you guys instantly. would let you knw once m back.

BTW, Ankur, do you think the ground you are talking about would be good for park jets as well? i would certainly want to fly my MIG  :)

Hi Ankur,

You know what... I cross this ground every time I go to Airoli. This is on Mahakali Caves Road which is just behind my house. (Maybe a 5 min drive) Last time, while coming back after flying, I was wondering if I could get a sneek peak into this ground. Now I know where you guys fly. Also, both of you are invited to my place to check out my hanger anytime. It would be great to have such a field soo close by. :) I am glad to see this.

Cheers !!!

Finally installed the servos & will take off soon...
