FAQ

What could possibly go wrong with hot Jets and lines?

Good question, but it’s a situation that is very easy to avoid.

The hot part is 4 inches long and takes approx. 1 minute to complete its cooling down sequence after use.

Most pilots can launch and land a Paramotor without the canopy and lines going anywhere near the motor. With the jets it’s even easier as all the weight is high on your back in a very compact bundle that is easy to manoeuvre.

You can order the jets with our protective shroud to make sure the lines and canopy cannot touch the hot part of the jets. 

How noisy are the jets when flying?

Pilots who have flown the jets, say how quiet they are compared to a traditional Paramotor, because most of the noise goes towards the rear.

Bystanders on the ground are the ones that get to hear the noise, especially when the pilot flies away from them. 

The locations that you can fly without upsetting people are remote locations away from the general population.

We fly them at our local airfield and so far we’ve have had no complaints, but all our flights have been short with long gaps between flights. 

How much do they cost?

This all depends on the size of jets and whether you want a single jet system or a twin jet system. It also depends on what options you’d like included.

Prices start from £14,000 plus vat and go up to £45,000 plus vat. See our price list for more information, or contact us for a specific quote.

What’s the throttle response like?

This seems to surprise pilots who expect a slow response, because of what they’ve heard about RC Jets, but everyone who’s flown our Jet Back Pack has commented on how smooth and instant the throttle system is. We designed the system to go from idle to full power in 2 seconds and full power to idle in 4 seconds. It is as responsive as a traditional Paramotor.

How expensive are they to maintain ?

Maintenance is very simple and much cheaper than most people realise.

The majority of maintenance can be done by the owner as the system has been designed to be as simple as possible with easy access to all components.

The jets should be serviced every 50 hours, so adding fuel, oil and maintenance  costs, the hourly running costs are approx £120

Do the jets have a flame coming out of the rear?

No, there are no flames  exiting the jets, so there are no concerns about setting fire to anything. Our jets use diesel, so no chance of a petrol fire like a Paramotor.

Can they be used on nil wind days?

Yes of course, the take-off distance depends on the size of wing and the power of the jets, they are very easy to launch in nil wind days and usually only need a few steps.

If you do need to run, due to using a wing too small for the jet size, then you’ll be surprised how easy it is to run with as they are high mounted on your back just like a good rucksack.

Why are the jets so close to the back?

We started our design by having the jets either side of the body to allow for air to flow into the jets un-restricted. This made it cumbersome and difficult  to handle.

We decided on a trade-off by designing the frame to allow for air inflow to be routed from under the frame, from the sides and the top, and found this to be just as powerful as having an open inflow area. Basically, no loss of power noticeable and it allowed us to build a very sturdy compact system that was easy to manage and use. This also helps to protect the air intake.

What’s the weight of the Jet back pack?

This depends on the jet selection and whether you want a single jet system or a twin jet system.

The lightest is 20 kilos and the heaviest is 32 kilos with 10 litres of fuel. 

Why does the Jet back pack have a high attachment point?

During the design and testing phase, we tried a low attachment harness but couldn’t get the geometry right to allow for a stable harness. The high attachment gives the pilot the best comfort and the most stability when launching and flying.

We have not dismissed the low harness attachment, but need to do further design and testing to make this as safe as we want it.

What is the flying time?

This all depends on the choice of jets and whether you want a single jet system of a twin jet system and also the size of the fuel tank.

The smallest single jet system lasts 20 minutes with a 10 litre fuel tank. The largest twin jet system lasts 5 minutes with a 10 litre fuel tank.

We also provide 15 and 20 litre fuel tanks as an option.

How secure are the electrical connections?

All our electric cables are military grade with connectors that cannot accidently disconnect. They require a push and twist action to lock and unlock them.

Are the fuel connectors secure?

We use braided hose fuel pipes and AN fuel connectors that have been used on racing cars with great success for many years, they are very tough and secure.

Our fuel system has been designed to allow for air intake without allowing the fuel to leak out, with our one way valves system and header tank.

Can a reserve be attached to the harness?

Yes, we have both left and right hip attachments available. The reserve can be added and removed within 5 minutes.

We can also add an airbag which takes less than a minute to fit and remove.

Can the throttle control be separate from the steering toggles?

We designed the throttle to be part of the steering toggles. If you let go of the toggles during flight the engines will automatically go to idle.

We can provide a throttle system that is fitted to the hand separate to the steering toggle, for those who want to use power when not flying the wing.

How easy is it to monitor the fuel levels

We currently use a timer as a temporary solution to fuel control. It’s a digital pie chart that shows how much flying time you have left.

We are working on an accurate fuel flow system that can be calibrated for different engines to provide a real time accurate fuel level and remaining flying time display.

Are they easy to fly?

If you can fly a Paramotor then flying the Jet Back Pack is very easy.

They are compact and simple to use, and produce no propeller torque. 

If you are new to Paramotoring then you’ll need to master canopy control first, with a Paramotor Instructor.
