Viper1990's Scratch Build Planes

F-35 profile

2009-12-20T19:52:00.000-08:00

This is a relatively simple to build plane. Because it is a profile plane. Meaning.. its not a full scale body. Just a 3-plan view put together to look 3-dimensional but it's not. It's advantages is that it could be built quickly at a low cost. Around 90% of the total cost would on the electronics.

I've decided to build one F-35 and paint it hello kitty scheme! Its extreamly light weight at the end of the built. I've use 6mm depron sheets to built the entire plane.

Powered by a 350watts motor, it have enough thrust to do vertical climbs and mild aerobactics. Don't be too rough on this lady here or she'll break in the air! (i've seen one of my friend's plane got destoryed mid air while plunging down to earth at high speeds)

The best part of this plane is, if it breaks, just build another in no time at all! The electronics could be transferred over quickly.

Here are somepictures of the F-35 profile version.

Hello kitty paint scheme!

Heres me with my F-35

And of course my friends who flies other types of profile jets like the F-22, Mig29, Su-35

Mirage2000

Here is one of my favourite jet planes, Not only it is easy to build, it is fun to fly! In a sense, it's able to handle slow speeds (25-40km/h) and higher speeds above 60km/h. No worries about flying a delta wing plane because it's able to handle stalls very well , Meaning if the plane is about to stall to it's doom, just throttle up and it'll fly away! This plane here is partially made of white styrofoam and blue foam for the wings.

White foam is very light yet brittle. But, once again who said plane is built to crash? Don't crash it and you need not worry about the brittle material! With the light weight structure, the plane is able to perform loops/barrel rolls...etc with ease.

(Remember to paint the plane to look good and attractive!)

Cleared for take off!

And there she goes!

1.8m multipurpose glider

2009-12-20T10:31:00.000-08:00

I build this glider for 2 reasons.

1) Bomb drop (built with a radio controlled switch operated bomb bay )
2) Aerial view (Can accomodate a camera up to 150grams to be fixed on the plane)

Thus ,its multipurpose... Oh, and it can also do stunts like loops and rolls. But not really recommended because it is a glider. This plane can catch thermals and stay up there for quite sometime. The glide ratio is great (40:1) when the throttle is cut off. The plane takes almost forever to get down back on land! It is light weight, only 800grams , the wingloading is at 8oz/sq ft. Making it a very light floater. gentle and easy to fly. Very suitable for starters in rc flying.

Skybox

2009-12-20T10:08:00.000-08:00

I am in collaboration with the aeronautical students providing knowledge in building, aerodynamic calculations and electrical wiring. (oh and flying the plane too!) Project started on March 2008 and ended on January 2009. This is one of the most massive plane i ever flown it's power reaches 2500watts producing nearly 8kg of thrust. Massive ammont of power enough to pull this plane weighing 11kg , running 30meters down the runway to lift off!

This project is in par with the global hawk's project

The team and I madiened this plane at woodlands flying field. We've choose this place because of it's large flying area as well as the long runway.

Global Hawk 120mm EDF

2009-12-20T10:01:00.001-08:00

I'm working with a few students in collaboration to build one of this giant beauty, The global hawk. Project started on March 2008 and ended on January 2009. Wingspan at 5meters weighing at 11kg, It have a powerful powerplant to get it flying.

This project is in par with the Skybox's project

The material used for the plane is mainly depron and bluefoam.The fuse is depron wrapped around a plywood structure while the wing is airfoiled out using whitefoam and glassed it using fibrecloth.

The motor in the 120mm edf can deliver 2200watts of power producing 5kg of thrust. Enough to lift the giant plane up in the sky.

In my early days of scratch building

2009-12-20T07:05:00.000-08:00

Time flies when you're scratch building!...., when i look back at them, they are my milestones in rc planes. They look crappy but they are the strong foundation that helped me get started in scratch building and rc flying. I've learn building and flying at the same time so the standards in this 2 areas are always on par with each other.

Enjoy the pictures of my very first attemps in scratch building planes!

Mirage2000 first attempt

Mirage2000 with lightings!

Got one of my friend to build his very own MUGI plane!

F-16 chuck glider built in school out of balsa!

My very first (bought from store) RC plane, not surprising was the nicest looking around too

My First "puller" plane , cessna 174

Mig 15 (yep,very crappy)

Boeing 777, i doubt it looks pretty much like one -_-

Taken from another angle...still looks crappy!

F-16 built, ugly, but hey it flies!

Fat F-15 pusher. Very very slow and ugly plane! but once agian it flew!

My first flying Wing

Attached lights to it so i can do night flying
