electric vehicle ? watch video of this electric Paraglider !

yeah
big dollar..

ANND: don´t expect them, to get much older than 100-150cycles and 2-3years (at least at currents i use)

to be fair:
the pack costed me ~160US$

but: i have also paid 90 US$ for a twice as heavy NiMh-pack for that heli.. (12cells, 3300mah)
and this pack lost punsh after 40cycles and was useless (too high inner-restistance) after 3 years as well..

so in this rc-heli-application the lipos are far better:
costs (over the cycles) less,
have about same power,
but weight only half weight
and offer more capacity
handling is also easier than with NiMh

One of my micro heli's, MS Hornet II. Usually flown with a TP1320 3s pack. I also have a T-Rex 450, and a few junk micros like Hummingbirds.

the TP1320 is - i think - the battery (with more than 10C capability) with most Wh/kg
(in the 190Wh/kg region)

other cells are much heavier..
for example Kokam 1250mAh..
also it has 100mAh less rated mah inside its more heavy..

result: only 140Wh/kg

wondering that there are Hornets still flying..
it seems to me, that the T-Rex450 has "killed" somehow the market for the Hornet-typ fliers..

[Kraeuterbutter]

oh..
you seem to be right..
it looks like a Predator 30 on the paraglider

meanwhile there is even a bigger predator (the Predator 37) on the Plettenberg-homepage

funny:
they say on there homepage, that they will not take responsibility for using Predators, Xtras or Terminator motors when used in man-carrying planes
*lol*

Most powered paragliders run on 2 stroke motors. This gives them a small but poweraful engine to produce thrust. 2 stroke motors can be tempermental, and require regular overhauls.
An electric paramotor may be best suited for pilots willing to trade shorter flights for a simpler and hopefully lower maintenance engine. Prop noise accounts for most of the sound produced by paramotors so electric paramotors are not really that quiet.
