Good health to Yours Family !

=electric is cheaper,NO need in music !100 hp Rotax Phoenix towing
K7 has "skid" so at the beginning of aerotow you need higher static thrust. Important is to start to move=electric is cheaper,NO need in music !
or=also three blade prop could be acceptable....
=yes,for glider towing mashine, not a soaring one...The CR flight solution probably give a lot ot thrust,
(my experiment,in work...)CR FLIGHT system
You are right - for tow plane could be an option. However pilots are interested in universal options and I don´t want to allow to pilots to change props=yes,for glider towing mashine, not a soaring one...
tow plane could be an option.
That is true
=many,many work for tow planes ...
=sailplane,glider should have high L/D ...sailplane enthusiasts.
Hello!View attachment 99480
I tried presenting this to a group of sailplane enthusiasts. I never found the slightest interest from them so I gave up on it. Bought a Cherokee and moving on.
That is a great idea for a glider installation like that. Just shut both down on failure of one and have emergency procedures that are same as for glider. I like it.Hello!
Seems that concept with two small motors is popular.

In case of EASA / FAA certified glider is modification difficult - only holder of type certificate can allow such a modifications.
In homebuilds world is your limitation only your imagination.... and money...
If you use electric propulsion you can use multiple motor design (at least in Czech Republic). The only condition is that in case of failure of one motor the other one much switch off automatically (reason is that UL/LSA pilots are not trainer for asymetric thrust).
So now you can go ahead![]()
To stay "glider like", there is also the solution tested for the "Euroglider" :
Two small pylon over the trailing edge of the wing with rearward folding props.
Drawback of e-genuis and sunseeker duo configuration is that the vertical tail plane and tail cone must be heavily reinforced (so only possible on new designs), and have quite long power cables (both problems add lots of weight). Also, with all this weight "behing", you would need batteries under your feet, or move the wing rearward (of course they used the second solution, again possible only on new designs).
From the 2kg of copper I installed in my FES glider, I believe Egenius has at least 10kg of power cables in the tail...
The problem with the Euroglider configuration is that it is not legal yet (expect on the prototype to help convince french regulators that there is no problems)...
Euroglider team is only working to adapt CS22 (certified gliders) application in France, forgetting about ather countries and other reglulation (CS-VLA, ultralights...) that are much more potential to see the developpement of new planes with this configuration...
=allmost "blind landing"...?nice places in Alpes....
