Now that looks like fun!

[Jan Olieslagers]

What are the engines? What fuel do they burn, and how much?

[C42]

Jetcat P200SX model turbines (55lb thrust each) run on Jet A1

[rmcb]

I want one.

Make that two. Just in case...

[Noah Zark.]

It'll be brilliant when they fit the reheat! I want one, I want one!

[Torque Tonight]

Bentley Continental fuel economy coupled to Austin Allegro performance, I suspect.

But I'd still like a go in it.

[172driver]

Cool! I want one!

[abgd]

Do they come in turboprop?

[AdamFrisch]

These are straight pure centrifugal turbojets for the RC crowd, so they're very inefficient. If these engines could be coupled to a bigger fanjet in front, thrust would probably tenfold. Or a gearing for turboprops.

These engines probably burn around 6-8gph per engine, which is about 16gph per hour. This is not that far from what a Rolls Royce C250 (that's in the Extra 500, Silver Eagle P210 and Bonanza turboprop conversion) burns at economy cruise, wringing out 450hp...

[C42]

It's burning 1ltr a min at the moment, there are a pair of P 300 sx engines being built by Jetcat for it which will give it 50% more power. They will be fitted when they arrive. I have to remove the ailerons and stiffen them first before it flys again, they were twisting.

Turbo prop option is a simple bolt on, all systems are the same but there too noisy (props doing 6k revs)

It does strike me a little like the worst of all worlds? Horrible economy with poor performance, range, capacity, etc. Loads of noise and no benefits. It doesn't look like it's pressurised either!!

But as others have said, I'd still love a go!!

[C42]

Don't take it serious, It was only built for a bit of fun! I have other aircraft for touring, aeros, displays etc. I just fancied a jet, got talking to a friend and he was just as keen so we did it

I must admit the Jetcat with 24oz/min of fuel flow per min at full power (55lbs thrust)and a TBO of only 25 hours has little appeal. There are several engines developed for the UAV market that beat those figures by a very long way.

A similar engine that is only 1kg heavier from AMT develops 88lbs of thrust rather than 55lbs. However sea level fuel increases to 39.5oz per minute, that drops greatly with altitude. TBO is 50hrs.

MicroJet is the engine of choice for serious UAV operators, a 17.5 lb engine will produce 200 lbs of thrust for the same fuel flow as two Jetcat engines producing 110lbs of thrust with a TBO of around 200 hrs.

Not aviation but funny (and jet powered):

That's a mate of mine (Josepi) in the wheelchair, I have driven it and I can assure you its much more scary than flying the twin jet!!!

I had a Sirocco microlight with a Rotax for a while before they got grounded.

It was awful in lots of ways (spoilers, wire bracing, kingpost, funny wing setup), but boy was it fun! And it could outlast my bladder by a factor of about 3!

I believe there's now a SSDR version out.

CG

[C42]

That is the SSDR one, it was just too heavy for SSDR with with the engine on the back. Take a 35 Kg engine off and put two 3 Kg engines on and it's well in

I seem to remember a "Dave" in the Watford area who was a Jetcat model aeroplane dealer, his dad was a well known glider pilot - Is that the same Dave/C42?

[C42]

No it's not! Lol!! But I know Dave and his dad Mick well.
His company is called Motors and Rotors but the engines came direct from Jetcat in Germany with full factory support for the project. ( same engines as Jetman uses on his wing)
