How to build RC FlyboardAir after Franky Zapata ?


Hi,

could you elaborate me on what engines do I need to source to build RC FlyboardAir after Franky Zapata

I visited his website
https://www.zapata.com/en
to find no details

from
https://edition.cnn.com/travel/artic...ard/index.html

"Last Sunday the 40-year-old former jet-ski champion took to the skies above Paris at the Bastille day parade, capturing the world's imagination with a board that can reach an altitude of nearly 500 feet -- with the potential to go much higher -- and a speed of 140 kilometers per hour.

"Zapata spent three years creating Flyboard Air, a jet-powered personal aerial vehicle. The key he says, was being able to place five turbine engines over conventional electric propellers to allow intuitive flight controls designed around the human body.

Since flight time is limited to 10mins I would like to know how did he succeed to cross the La Manche Channel


If you have already started to build alike RC FlyboardAir, let me join your team.

If you are looking to build an RC scale model of the Flyboard, the engines needed will depend on just how big you plan to make it. Control and stability will be very similar to what is on every multi rotor, just find one with 5 motors to steal the controller out of.

"place five turbine engines over conventional electric propellers

could you forward me to some web links with turbine engines, which can be combined with electric propellers ?

From what little I can see in pictures my guess is he is using jetcat P300 turbines.

I believe that I saw something about his "board", which said he was using four P400 JetCats. That's why he had the fuel issue trying to cross the English channel without refueling.

Considering he is trying to get government and military contracts I don't think you will find any specific construction data on his system...Trade secret!

in local magazines you can get detailed drawings and detailed description of his aircraft

on the internet you can get Ts of images for FlyboardAir

the problem is always the same

How to build Budget RC FlyboardAir after Franky Zapata

don't expect me to buy 5 x

P400-PRO Turbine Engine, 89 lbs Thrust, by JetCat


Item: JC P400-PRO
Price: $11,999.00

to spend $60,000 for 5 jet engines only

There must be other way, other manufacturer of jet engines to cut the budget 10 fold

Do you remember the first two-wheeled self-balancing, battery-powered electric Segway invented by Dean Kamen, priced at $30,000 ?

Today you can buy alike two-wheeled self-balancing, battery-powered electric hoverboard at $300 or less.

So electronics, gyroscope, control system can come from a drone but what we really need is jet engine priced at $200, manufactured for RC community in China.

What makes RC jet engine so overpriced today ?

Can you explain me, what makes the price of RC jet engine to top any other RC product ?

Turbine is just turbine and if manufactured in volume, can make the price to get down.

Segway was the first
Ook, sophisticated gyroscope's levelling control

alike challenge to control 5 jet engines

But who can build jet engines at $100 and at what trust specified ?

(dreaming.....)
Next year we all can fly on our $1,000 flyboards in thin air.

some hints from Internet search

The problem is none of these so called "tin can" turbines work, at their best they are blowlamps. Working turbines are precision made with tight tolerances using specialist materials. Compressors are now often made using multi axis CNC mills while the turbines blades are specialist castings in Inconel and will be failed for a single flaw. All of this costs money even at mass production levels. Costs are already coming down from earlier levels but turbines will never be a cheap buy, your idea of $100 costs are fantasy, a small glow engine costs that and they are much lower tech. At the size of turbine needed for your flyboard the amount of sales will be low so the cost will always be high, no maker will build large amounts in the hope they wil be bought.

There is a room to cut prices 10 fold, to introduce low cost turbines manufactured in volume quantities

I exactly recall talks when Segway entered a market at skyrocket price

Today you can drive alike vehicle at a pocket money.

Exactly the case with 3D printers.
The first were priced at $Ts

today you can buy small 3D printer at $300

So there is a room for prices of turbines to fall thanks to Franky
