Nicely done!

Pretty cool! I think he needed more stones, some larger rocks and a few potholes for his testing...

I was thinking the same thing ..... why is he building an OFF-road jet car

Very cool though

 

[StephenSchandelmayer]

Very awesome, it would be quite the event if that thing started tumbling at high speed.

Will it come with a fire extinguisher???

Yeah in the UK long smooth straight clean roads are a bear to find.
He might need more than a runway's distance to get his rig up to MAX speed. IDK.

It would need a lot more downforce to try getting it up to speed. Now it will go into any direction the jet points.

I often considered making an emergency parachute myself, but never did...

Theoretically (and probably practically) he could generate downforce simply by tilting the rear of the jet up by a degree or two, no?

In RC planes they have servos move a turbine or edf up and down, it is called vectoring

In planes that is called vectoring

Thank you, that is the word I was looking for. Though I always thought of vectoring as an active movable component of a jet engine. But functionally, yeah. Same thing.

If the jet was actively stabilized yes, but at this application/scale, any rock/front flip will change the direction of the propulsion, unlike planes (in air/big/tones of weight)
In a car, wheels of the ground stops the propulsion.

I'm no rocket surgeon, but I'm pretty sure if a plane flips it changes the direction of the propulsion too...but I get what you're saying

A plane would already have taken off at the speeds it becomes dangerious

The big difference with airplanes hitting turbulence is that they have control surfaces in all 3 planes (pitch, roll and yaw) - they operate in all 3 dimensions.
With the car, you only have yaw control (steering) - if you hit a rock and pitch up, there is no control to bring it down. And since the engine thrust is now upwards, the car becomes a plane ... for a short while.

I want one just for the sound.

This is what I envision it looking like (incidentally this is one of the most epic RC jet fails of all time...it's well worth 65 seconds of your life).

I love the wife, "I'm gonna call you right back, my husband's jet is on fire..."

That is how it will look.
It is interesting that the fire extinguisher sounds exactly like the jet engine.
I was expecting a lot more cursing ..... and tears, or perhaps that is why the video cut off.

When I was designing the carbon body that Raz poorly used I was talking with a guy that was contemplating a Jet/Turbine powered RC car. With enough runway you could break the record pretty well given the thrust they have grows as it goes faster.

118mph This thing may have 150 in it

 

[StephenSchandelmayer]

I'm torn because yeah the motor is pushing the car down but I have to imagine it's also just catching so much air on top to flip it over. Hope he keeps trying though, really awesome build
