Hi!
I love aviation and I chose gliding as fun, reliable and quite cheap way to fly!
For launching glider in the air you can use two ways - towing with airplane or using winches
Towing with airplane is not cheap and you need towing airplane, pilot for that.
About winches it is quite cheap, but old winches based on combustion engine can lift glider up to 300 meters. And modern electric winches can lift gliders up to 700 meters, but the cost of this winches is very high.
In this project I am building electric gliding winch based on parts of electric cars:
Electric motor - EM57 from Nissan Leaf
Inverter - from Toyota Prius
Battery - Tesla/Toyota Prius
This is ongoing project, and I will write all updates here, but you can see the history of development from the beginning in my telegram channel and facebook group
