    Just taking the battery out without it being anywhere else, moves the CG forward.

    I see, Denny. I assumed it had something to do with engine running to cold or shock cooling. The 120 has amazingly good heat, so I'd like to keep that going if possible.

    Alright, what's AOSS

Coming from a low HP aircraft you are going to really like the 150hp cub. Prop will make a big difference so test fly a few if possible. A good test to see if spending a lot on lightweight mods is simple. Fill both tanks, fly for 1 hour (that should be about the 50 lb weight loss you want) now ask yourself if you notice any big change, do a landing, and takeoff. On a cub the three things than really make a difference are Borer prop, Bushwheels, and AOSS.

    Have you flown behind a Sutton exhaust much? They kick out a pretty good amount of heat. The cub that I share with my brother has a Sutton and it'll keep you toasty even in the coldest weather. Equally as good as a hot rod exhaust IMO.

    Itís been great, I got my license soon after the day we met. I am waiting on a maintenance item to transition from the S-20 to the S-21. Should be up and flying late this week.

    Glad you are enjoying Utah

    I agree that a Sutton puts off a good amount heat. It’s enough to keep a coffee thermos hot or cook a chosen foot. What you don’t get from the Sutton but do from the dodge or LEE is the radiant heat coming off the firewall. The difference in the middle of the summer is substantial. The combination of a Sutton and disconnected heater box makes it tolerable.

    Plane does need new bungees, I guess it's only $2000 more to just get the AOSS while at it...

    Also just want to comment on how fantastic this forum is. I came in with a question that I'm sure has been asked 6 ways already but not quite in the way I wanted, and people were all just happy to fill me in with their experience. Thanks folks

    I have a 5 hour dual instruction (all one day in the backcountry) required for insurance and then it will be based in Heber. Come on over.

Donít want that possibility in the passenger compartment.

    If that battery catches on fire it doesn't matter where its located, you have a serious problem. More than likely it will be fatal if you are in flight.

    If you would start before 10 pm we might feel bad for you, but we know that as a married man you must take care of the cats, dogs and goats before you can go to work

    Wait until you have kids, you will understand more. And we do realize your rebuild was prior to marriage... that helps.

    We tease you because we respect how hard you have worked to be where you are today. Just remember we are warning you you will slow down with age...

    Now, EarthX- remember that they don't charge very well if cold. I am moving mine into the cabin to get heat to it because it does not charge well in winter.

    Any pound reduction under $100 is a good pound.

    Agreed. I keep hearing these claims about EathX, yet I only know of one incident and it smoked the first time it was powered up. THAT leads me to believe it had problems with the install not the battery. 'My brother-in-law is a mechanic and he says....'

    Had to swap that AC fitting for an AN I see. Warbird guys want all that AC stuff now to be completely original. Looks like an interesting project.

    Josh Svennington was telling me about having a runaway EarthX in his experimental helicopter. From everything I have read I don't see how but he gets pretty worked up about them. I know plenty of people running them with no issues at all.

I think some of the problems that the Li-ion batteries had were miss- attributed to the Li-iron batteries and thus sullied the reputation of both technologies and specifically the Li-iron batteries. I believe that most if not all the fires and runaways were in the Li-ion series of batteries ( I could be wrong, so please don't take my meager knowledge as the gospel) but you now have a couple of terms that are similar but different (Li-ion Vs Li-iron) to google search.

    Hope this helps

    This has been my impression as well. Two different chemical formulas.

    https://earthxbatteries.com/our-batt...ery-technology
    "There is a lot of talk about lithium batteries these days, but not all lithium batteries are equal. There are dozens of different types of chemistry used in lithium batteries. The EarthX batteries use cells made of Lithium Iron Phosphate (LiFePO4) chemistry that was developed in the U.S.A. This chemistry is the highest performance, most robust and the safest on the market today."

    Yeah the AC was cracked. Canít get them anymore. Had to re make the line. Iíd be surprised if those fittings have been out in the last 80 years. They were stuck.
