Default Electric Self Launch System

Hi everyone,

My name is Emir Sherbi, i'm a mechanical engineer from Argentina. With a partner who is an electronic engineer we've designed an electric self launching system that can be retrofitted in most of the composite sailplanes. Some of you may be saw my booth in the SSA convention in Reno with the mockup of the prototype.
The idea is to sell it as a kit so you don't have to ship the glider to my country. The modifications to be made are very simple. Any repair shop have enough knowledge to do it.
These are the links for who are interested in following the project.

When I stopped by your booth, you indicated that this system is still in development with much work left to be done. Is this accurate?

Hi Tom


The most difficult part that we are working on is the battery pack supplier and testing. In other hand we also are starting to build our own motors, not only for this application but also for another types of vehicles (mostly agricultural). But for the US clients we can supply any already known motor brand to power the kit.
As you can see on the pages that i shared, we are starting to work on the fuselage. The pylon is on its final revision for flight testing but we are still working on the batteries.

Regards

Which battery chemistry are you going to use?

INR and IMR, depending on the flight mission.

INR 18650 2500mah Battery (2 Pack) - Samsung

20 amps of continous discharge, the Samsung 25r has been the go to battery for most vapers because of its authenticity and its transparent rating system. In terms of cell degradation the Samsung 25r has been a reliable source of power.

Flub, are you implying this project is vapor ware?

Not at all. I think it is brilliant that millions of vapers have volunteered to do rapid discharge testing of INR battery technology. And a mass market battery like this should benefit from manufacturing economies of scale and competition.
