Electric Motor Controller

Greetings - my first post on EAA forums!

Question - I'm looking at purchasing a nice factory built motorglider with a DIY gas to electric motor conversion using a Rotex RET-60. The owner reports that the controller and inverter provided quickly failed. He's tried a couple other brands, same problem.

Anybody have experience with controllers & inverters and can recommend a reliable source? The installation looks to be very well done but is it possible there are gremlins in the system elsewhere?

My knowledge of all things electrical wouldn't wet a thimble so suggestions are most welcome.

thanks!

Paul Dye, Editor at Large for KITPLANES magazine, has just converted a Xenos motorglider to electric. I'd scan through his articles...

Thanks, I did a quick scan of the first article and noted that controllers need some firmware adjustments - which requires a rather skilled programmer.

Any aversion to reverting the glider to a gas engine considering the e-failures?

To be honest, all things considered I think I would prefer a gas engine.

But - since this project is so close to the finish line, if the controller issue can be resolved, the electric motor would be perfectly ok.
