Additional elect power?

[E. D. Eliot]

I'm training on a Sling so I'm around their shop some. They are constantly building up new Slings to sell. Saw one which had a Rotax? alternator attached to the upper left hand area of the engine PSU. Bolts right on - I think that it is a 15 amp alternator. Looks like a very clean installation and I guessing - that that alternator was created or blessed by Rotax.

So, i'm interested to know if anyone has installed such an alternator to his/her RV-12 after certification? The cowling of the Sling is longer so, to install this type of alternator on my 12 would require considerable cowling rework. Probably need to add 4-5 inches to the front of the cowling. And add a prop spacer alike the one on the Sling. I'm a few months or a year from doing this so I have a while to gather opinions and facts. Your thoughts - Thanks, Ed

There is also an alternator that can be mounted to the rear of the gear reduction unit. I believe that the vacuum pump mounting pad is used for the purpose. That would (probably) not require a cowling extension, however the pitot tube would have to be relocated elsewhere (like the wing). You might want to check that out.

You might want to check out Edge Performance. They have one that mounts to the back of the engine. https://shop.edgeperformance.no/en/home/458-ep-32a-secondary-alternator.html
