Lightweight Starter

[lancef53]

I was looking around, and I think that the battery I was wondering about was the odyssey battery, it weighs about 15 pounds and is used in supercubs with the big engines, It should work fine for a C-90.

Seeing as I started this thread in 2004, I thought I'd chime in and let you know that I got my starter / battery installation inspected and approved by an inspector from the Detroit FSDO this past fall. I went with the Skytec / push button starter and installed a Concorde RG Battery in a box behind the rear seat at the same place they put them in the 7EC. I use an RV type trickle charger to give it a boost now and then but the battery can go a long time between recharges.

I am very happy with the installation and don't miss having to hand prop at all! I also appreciate the provision of auxiliary power which I use to run my Garmin 296 GPS and hand held radio. I am still considered a "non-electrical" aircraft for the purposes of transiting a mode C veil, etc.

What Tim did is another issue that I have seen several people address.

They usually put a cigarette lighter outlet or other 12v power access point during the installation. This way we can have a better source of power for our radio, GPS and lights if needed during the flight, but the plane remains a "non-electric" airplane legally.

You may want to consider using an Odyssey drycell battery which weighs 15 lbs. Aircraft lists the battery as part #11-01945 and is certified for the Super Cub. This way, you could put together a total loss starter system for about 30 lbs. Since an electric starting system is preferable in the eyes of the FAA, I would think approval would be simpler.

Well, we have the starter(sky-tec) and battery in hand, what did most people do for a battery box? We were thinking about keeping it on the firewall, like the later model planes.

Thanks for the help!!

Lance,
Since the Odyssey battery is sealed, all you need is a hold down, not a vented and drained box like you'd use with the old conventional batteries. If you want to attach it to the firewall all you need to do is rivet a piece of aluminum "L" extrusion to the firewall for it to sit on, a smaller one above it to hold it down, and nutplates to either side to hold an aluminum "U" bracket.

In my case I installed an aircraft RG battery in a aircraft battery box I got from a salvage yard. I put it behind the back seat where it would go in a 7EC. Having a certified battery in a approved box in a approved location may have made it easier for the FAA to approve my installation although it is a little heavier.

Does anybody have a copy of their 337 that they would like to share? We are doing the sky-tec starter and lightweight battery in a 7bcm converted to a ccm, and our A&P said any paperwork would be helpful.

Thanks, Lance

If someone has a copy, pls email it to me as well and will post it on the bulletin board.

Hi Lance. go to these site for paperwork information. If you have Sky-Tec p/n C12STC2 this starter is FAA PMA approved part and is a simple install and sign off by the A&P.

If you go the STC route then the A&P just fills out a 337 and has an IA approve it and file it.
Sky-tec has PMA approval : PMA NO: PQ0852SW
