Gill G35 Or G35M

Tomkatz · Post by **Tomkatz** » Sat Mar 19, 2011 3:41 pm

Guys,

I have a bad battery in the aircraft and a never used Gill G35. Does the MX-7-180B require a G35 or a G35M? The battery is under the seat. I know the "M" stands for manifold and I'm assuming this is a vent manifold.
Any additional knowledge is appreciated. BTW, it is a 1996 aircraft and electrlite has not been yet added to the unused battery.

Thanks in advance for any help!

Take care all,
Tom[/list]

You may want to consider the Concorde Recombinant gas Mat battery.

This is the one is standard equipment for you bird:

This one is PMA'd and approved:

I think you will find many very happy pilots flying behind an Odyssey SBSJ-16 dry cell battery: http://www.skygeek.com/odyssey-battery.html.

These things have plenty of cranking power, and they cut your battery weight in half. They are approved on cubs --PMA, and it should not be too hard to get a field approval on a Maule.

The thing is, I have on hand the Gill and will have to use it at some point. I would like to use it now. The last 3 batteries which have been in the aircraft have been G35's. I just can't find a 337. I will look on the original equipment list. I do look forward to the new gas batteries.

Anyone have the 337 paperwork and installation photos for one of the Odyssey batteries in an M-4 210C? Hopefully I'll get another year or two out of my current battery but I like the thought of the lighter battery under the front seat instead of the heavy one way out back... Saving 12lbs plus cable weight would be nice.

I did the odyssey batt on the firewall last summer, one of the shops on lake hood did it and has all the paperwork. One of the best mods I ever did. I had battled starting issues with the Gill in the tail and can't say enough about the odyssey. Under the seat would work, especially with the big motor airplanes for CG, but the firewall mount is great for preheat and keeping the tail light. All total I got rid of 31 pounds on my empty weight number. I would strongly recommend this to anyone.

Thanks ,
Tom

Do you know if the Odyssey STC covers a MX& 180B?

I think the only STC for the battery is in the Piper cubs, but it is becoming a quite common field approval. I know of several Maules and Cessnas.

I have paperwork for odysey in the mx7 and I've done a couple of M-5's as well. It's an easy field approval up here in Alaska but you'll need an IA to do the paperwork for you.

You need to use the odysey SBS J-16 (or Hawker same model) as it's approved for aircraft use due to it's explosion proof case. I also use the Odysey hold down case at the bottom of same page as they're inexpensive and battery fits it nicely. I split a long hose clamp, attach it to the sides of case for the battery hold down and usually trim up the top of it to allow easier battery removal. Firewall works nicely as you can preheat with engine as MikeW mentioned.

Mikew,

31 lbs off the aircraft is amazing! Not easy to get that much weight out of the plane no matter what you do, well maybe if I only drank light beer.

I echo Tom D's experience. I have had a lot better reliability with the The RG-35AXC Aircraft Battery From Concorde Battery Corporation.
