Two 1/5 scale rc cars with TURBINES! What you think!?

... but I don't really get the point as once built they're pretty much unusable as a fun RC car...
Actually not so - those that know me will know that I have a large 5th-scale jet car also. I just set it to the safe maximum fun speed (40/50mph) for what I want to do, & use it the same as when it was a 2-stroke. And these engines will put up with tumbles & bumps, no problems - they're not delicate, once built!

Indeed Arif! and yes I agree, growing friends with you and more jet buddies since building these beauty's!, talking about speed with these etc I've thought about stopping better..... Here is what I have fitted :-) And these engines will put up with tumbles & bumps, no problems - they're not delicate, once built!

If I weigh about 10.5st/70Kg ish, what size of turbines would be needed to make a full size quad 'copter' which could do VTO/L with me on board?
I'm basically fantasizing about making one with turbines, bucket seat, hand and feet controls, perhaps giant airbags etc (touch screen, GPS, engine/fuel statuses etc). It'll never happen, but I like to paint detailed mental pictures...

Their engines are easily compatible with manned-flight vehicles. Say, their smallest produces 40kg of thrust - so as four, is tonnes (not literally) in the quadcopter application.
Personally, I'm more interested in making a person-carrying hovercraft - so the downsides of anything like a crash are going be very low indeed (unless you make it go fast). You could then think about just one of their engines - so the one producing 120kg of thrust. I think they're about £8000+. Bang-for-buck - that's amazing!
Without that, you're looking at second-hand 1:1 heli-turbines.
My dream model project, if it had to involve flight - would be of the Harrier jumpjet. S'all about those nozzles!

It's the smell I love coming back from my garage - deliberately soaked in!
I agree there I love the smell of burning paraffin in the morning, it's like perfume!! These small gas turbines can become addictive! Actually in the process of redesigning and building my smallest ever engine in whatever spare time I have at the moment (third year PhD student, so free time is like gold dust). To give you an idea of scale, the turbine on the right in the picture is 66mm diameter and a fairly common size for these small engines, the compressor however is 32mm! Had an intermittent combustion instability problem in the previous design which cooked the rear bearing destroying the engine in the process, which was almost instantaneous because at a shade under 300,000 RPM any lubrication problem is instant mechanical death 
... Ah well, sourced another turbocharger in good nick (from a Smart roadster) now onto version 2!!

Thanks for the info Arif, interesting insight. Do you think a turbine could be hooked up to some sort of electrical generator so it could feed four decent output electric motors? Then only a small failsafe battery to get the craft down to the ground safely would be needed.Their engines are easily compatible with manned-flight vehicles.

Do you think this is a possibility?
