These guys , have some what appears to be, good quality E-motors
and folding props.
Perhaps go with their motor, and controller+interface ; and build
your own batterys , to save some money ?

They look like they have some nice kit

No it just moves less.
=only 2 details ! (SIMPLICITY...)

=the photo +differential gear with 2 CR propellers= 55 kg...

+circa 40 kg FREEWING.(BKB-1 like)

Next step=HYBRID drive system.( <115 kg)

My friend is using Geiger propulsion system in his beautifull trikes. Geiger use modular "plug and play" system working with low voltage.

Interesting looking trike.

#### John.Roo

##### Well-Known Member
This trike is designed for ATOS hang glider wings
Therefore is trike very light and aerodynamically efficient.
It is possible to have it with smal two stroke engine or with electric propulsion.

=SILENT GLIDER looks better...

(aspatially with IMPACT or PHANTOM rigid wings !)

Sorry Henryk, in this case I don´t agree. Reason is not design, but control lines.
When you fly airplane you expect how controls are reacting.
When you fly trike, you also know how to fly it.
Most difficult difference to keep on mind are pedals - on trike is control of front wheel opposite in compare with airplane.

In Silent you have special combination.
Controls are looking a little bit like in airplane, but to go up to have to push (like on trike).
To go left or right you use "steering wheel" (I don´t know exact description - look to picture below).

You really have to have on mind this "combination" - especially when you fly with more types.

As far I know is was tested also Silent version with control stick

But than would be probably better to use also "airplane like" pedals system to control front wheel....

Driving a car if you hold the top of the wheel you move left to go left and right to go right. Hold the bottom of the wheel you move your hand right to go left and left to go right. Why aren’t we all dead?
If that hasn’t blown your mind hold the wheel at 3 or 9 o’clock and you move your hands up and down, seems to work fine???

=AERODYNAMIC, COMFORT are the clue...

controll systems are many,different,
f.e. KASPERWING=

=two halve stics= L, R, L+R...

or "semiclassic"=

I don’t say you should not buy it I am just conservative... If all goes perfectly is not a problem. When you have to solve quickly some non-standard situation you will feel the difference. Just my personal opinion ;-)

I thought about going with a trike ; but i didn't want to keep all the
drag of the control frame and control wires. I'm going with the idea
that nestofdragons presented ; for a way lower drag solution :

Nice! You definitelly reduced surfaces to absolute minimum

Flying wings looks elegant.

alternative for IC engine TORNADO 280...

Small generator for single seat "hybrid" airplane?
12,00 kg / 6 kW continuous output power
Or maybe even for two seater
29,50 kg / 14 kW continuous output power

#### henryk

Small generator
=2 kg/ kW ?

-iff=
7 kg , 40 kW BLDC as 3-phase generator (1000 $) + 10 kg , 20 kW IC 2-T motor... ? (3000$)

=(4000 $) , 1 kg/kW ! + some PETROL... #### blane.c ##### Well-Known Member HBA Supporter =2 kg/ kW ? -iff= 7 kg , 40 kW BLDC as 3-phase generator (1000$)

They do seem a bit "pricey"?

I was also thinking that it is easy... just take BLDC motor, some two stroke engine... connect it together.... but is far not that simple. It only looks simple.

If you don´t beleive me - try to make one
Well working and "real life tested" range extending generators are practically not
existing.

It is still "pricey".

just take BLDC motor,
-BLDC is not 3-phase generator ?

=SYCHRONJUSE is better, but PRICY ! (f.e. EMRAX motores)
