jetkart - work in progress

Post by metiz » Fri Apr 18, 2008 6:14 pm

I've been building engines for close to 2 years now, time to make a vehicle for one. At the moment not much to tell other then: this is more dangerous then running any engine I build yet. I'll probably use a Talon 20 with an augmenter for this unless it becomes to heavy. Construction pics below.

Looks like a fun ride!
Anyone know the land speed record for a valveless?

Metz Monster!

Yep looking scary!

You know Square tubes buckle real good don't you?

Any more build and I would use round tubing.

The wide track I see as a plus. You must be like me and getting old.

The bike tires I see as a Plus. Less friction and able to be on down the road.

I have the Chines Engine that Eric Built , sold to Adam, that Sold to me I need to do something with.

I live in the boonies , desert, sand and Mexican neighbors. What can I do with it?

Maybe the Enics thing?

metiz -

All right, looks like you're aware that you need more of a truss in the vertical direction. Taking that into account, this looks fabulous. In my opinion, a lightweight trike is just about perfect for a pulsejet vehicle.

Most of the 'karts' we see have two basic design mistakes (in my opinion): they use small wheels, and the engine's thrust line is far too high. You want to keep both the CG and the thrust line as low as you can make them (and still be practical in terms of ground clearance and so on).

Looks great to me!

Why not using your Talon Dreadnought engine? :twisted:

Hey klubbson I hope your going to be there for his first run, you guys live pretty close as a far as I know!

Dreadnaught would be ok as long as metiz didn't mind getting a little...or a lot...of air-time :)

Racing red

Post by metiz » Fri May 09, 2008 3:23 pm

small update. found a nice bed frame on the dump and I used that for reinforcements for my frame. looks like a hotrod now with red racing stripes :P. The seat is there for show and needs some more work, but the position is about right. pic below

First own design, possible jetkart candidate

Post by metiz » Mon May 26, 2008 8:16 pm

Just design my first, long overdue, own pulse-jet. I strapped it to my jetkart to see how it looks. it's pretty awsome from where I stand :D
The engine, if it runs that is, should produce 60, maybe 70 pounds of thrust. still need to bolt an tailpipe to it.

big thermo first test. It runs! video

Post by metiz » Thu May 29, 2008 10:57 pm

First test of my very own Thermojet. It runs! - to bad about the HOLE I forgot to plug in the cc. Reaked havoc with my thrust controll but whatever - the engine runs. The engine could use some massive fine tuning: bigger intakes, less steap angle on the tailcone, shorter tailpipe- and cone, smaller cc (thanks to James for pointing this out). video below.

I don't remember saying any of that stuff lol!

I did say your intakes could be bigger, and your CC might be too long, other then I was not that critical! LOL
I did say all those dings are not optimal, but you knew that already ;)

Its your first Metiz engine bud give it time, it will be a ripper.
