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

[Bennyboy1983]

Just finished building these two beautiful pieces of art!, both make a insane amount of power and I now need a runway :-)

What is everyone's thoughts?, been done before I know but as I built one a few years ago I missed the challenge and built another, and another!. Here's one! http://youtu.be/3pF1gGwPJNo

Can provide more info on request of anyone's interested, most people think I'm bonkers!

Would love to know what that sounds like, mind you i wouldn't want to be stood behind it when you start it up!

[Bennyboy1983]

It sounds like nothing else!!!, worth seeing in the flesh!.

Are these pushers or driving the wheels directly?

An interesting engineering project if a pusher but I don't really get the point as once built they're pretty much unusable as a fun RC car. And only marginally more if driving the wheels.

Looks like a neat job though.

[Bennyboy1983]

These are both thrust driven, and the blue one I've used quite a bit now and is totally useable!!, just fast..... The other I've oy just built so not really used it much, I'm going to be building another with a turboprop turbine and gear reduction running 4wd which will be fun I think. And thanks for the nice comments yeah it's a neat install. I built this last year on a push bike...... I bottled it at 86mph!.

Now that is bloody cool. I much prefer that to the RC cars. More details please.

For me the fun of an off-road RC car is the mud, jumps, and rooster tails from the wheels. A turbine surely precludes a lot of that due to fragility???

[Bennyboy1983]

It's still fun using the rc car mind!!!! Real fun. The jet bike got loads of attention mind. Here's the first ever video of it and just testing at 1/3 throttle!. http://youtu.be/qUuA_etuBDc

Looks cool, what does a mini jet engine set a chap back these days?

THAT, is brilliant.

86mph on it. Kahoonas the size of the engines I should think

If buying new, around £1200+ would be a reasonable guide. If buying used with service history (they tend to need servicing around every 25hrs or thereabouts) then around £7~800+ would be the ballpark. Helicopters can go up as well as down, etc.

Surely that's asking for a batmobile body shell!

I think that is their USP



sorry

Funnily enough my response was the same as your mate with the camera. There's a lot of money on the back of that bike then.

I know nothing about RC cars, however anything that sounds like that and has flames is officially awesome

I used to watch Tractor Pulling on Eurosport for this very reason.

[ReaderScars]

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...

[Bennyboy1983]

You'll need a lot of money and someone who knows how to build it! Plus if you crash you'll die!, well maybe anyway. Turbines are crazy they really are!!. Both mine were just under 2k each plus everything else on top but worth it when you here THIS....http://youtu.be/_2raNLSaHeU

I've been building these small gas turbines for more years than I care to remember. Actually have a couple sat in my desk drawers here at uni that I use to help the second year aero-engineers when I teach the jet engine lab exercises. I love these things, also have a few commercial engines too. I've also just acquired an APU engine from a Chinook Helicopter free of charge via another engineer, should be interesting. I also remember the OP's bike from an Ebay sale a year or two ago and thinking, brave sod. Tried the same thing on a dodgy old Apollo mountain bike in the 90's albeit with one big engine and chickened out around 40 mph.




Just be aware that gas turbine powered cars accelerate quite slowly, and so you give it a bit more throttle, still not that fast, bit more throttle and then off it shoots at a ridiculous rate of knots.... it's mental, but fun The hardest problem I had was finding a big enough area of clean, flat tarmac.
