1/3rd Scale FLYING X-Wing Fighter!


Apollo Leader

Recommended Posts

There have been a number of large scale replicas of the X-Wing fighter from Star Wars through out the years. But how about one that can fly?!?!

This is being built by one of the rocketry groups in southern California and will be flown in a few weeks. B))

There is also a 1/4th scale Y-Wing fighter being built by another California group that will also be flown at the same event (Plaster Blaster):

Is it just going to fly straight up and then parachute back down? I'm just not seeing a pitch control anywhere. :huh:

After reading some of the details further, the RC controls and related mechanisms are apparently for controlling the wings in their locked/unlocked poistions during flight.

It flew! For about 3 seconds until it went boom.

HAHAHA! I so saw that coming. I'm no engineer but when I saw that the xwing was gonna be made of wood I knew it was gonna be doomed. The 4 rockets will just tear it apart and even if it doesn't, it probably won't fly straight up for long and may become dangerous as it becomes into a missile or something. :lol:

Watching the footage several times over from what I can tell it was a mix of being both underpowered and the stresses on the wing joints. About 2 seconds into the flight the X-Wing was about horizontal; it needed at least twice the initial impulse and two to three times the burn time to have gotten a much more decent flight. It was right at about apogee (top of flight) when the bottom right wing ripped off from probably the the stress of the motors, the X-Wing flipping over, and that the mounting points for these wings weren't strong enough (especially since they were designed to pivot).

IMHO, if they want to do this again this is what should be done:

1) If they want to stick with the same 4 AeroTech Redline M class motors for the realistic engine effect, they need to to axe the folding wing design and go with fixed wings, make a stronger wing joint, and find a way to nix 40 to 50% of the weight (typically with an unguided rocket you want to have at least a 6:1 thrust ratio or higher).

2) Drop the 4 M's, go with like a single P class motor, and get someone (like Pat Gordzelik) to make it for them. Unless they can find a way to make a more sturdy pivot point for the folding wings, this feature again should be axed.

When I saw the size of the 4 motor mounts in relationship to the rest of the vehicle, I feared something like this was going to happen. But sometimes we have to learn the hard way before we get things right.

There's been plenty of subsonic aircraft (prop, jet, and rocket) that have utilized wooden construction just fine. Obviously making these wings so that they would fold together in mid air made for a weaker mounting point and if the rocket had stayed in a straight vertical path it may have held together.

Here's another video of the flight:

Here's the big Y-Wing that was also flown; the parachutes deployed while the motor was still lit:

Pictures of the Y-Wing in flight; the guy controlling the launch is pretty darn close for an L motor!:

Obviously the Force was NOT with these rocketeers in Southern Cali! :lol: But my hats go off to both team for making two large and complicated flying models. :)

Closest video and from the side!

Watching it from this angle if it had held together it would have taken a cruise missile trajectory into the ground before the chutes could have opened.

Here's some good still shots of it and some of the other Plaster Blaster flights that weekend:

For those who want to see how a large scale model rocket is done right, here's the 1/3rd scale Mercury Redstone some guys from my group here in Nebraska built and flew done in Kansas last month (this is a 27 MB WMV file):

Great comments by the guy, particularly about increasing awareness of the hobby, designing for safety, and triggering the safety escape. Kudos to him & his team! Great way to spark kids' imaginations too! :lol: We need more of that in this world.

Awesome Redstone launch! Man, I feel sorry for the recovery crew...
