Re: EarthX
Another option 15# needs a 337 but only $240.

That's great! Though in my first model year 120, I'm keeping all the lead behind the cg I can!tonycondon wrote: ↑Mon Jul 24, 2023 6:25 pm Cessna 120, 140, and others now on the AML for EarthX STC. $$$ but saves 18 lbs over Concorde RG25XC. On my Christmas List

Re: EarthX
I'm sure all the 140A folks know this, but according to the STC approved model list, the 140A is not included.

Big Pro...weight savings.
Potential Con...lithium type batteries tend to suffer shortened lives when left fully charged all the time. I reduce my RC plane lipos to a storage charge of approximately 3.85V/cell when not in use to maximize their life. I-phones have a setting for optimized charging where the phone waits to charge above 80% until it thinks you will need it also to maximize long term battery life. If I was to put an Earth-X battery in my plane I would want to try to figure out a way to drop it to a storage charge in between flights and then fully charge it prior to flying because at $700+ for the battery I would want the most life possible out of it. With that said...if these batteries prove a 10yr or so life in the field, my worries above would not really matter. The long life would more than offset the cost especially considering the weight savings.

Re: EarthX
I would highly recommend removing your battery box and installing an odyssey with its box. This will save you about 10 pounds over a concord and the factory box, and cost less than $300. For $700 that battery better fly my plane for me. Is another 8 pounds worth another $400? I guess for some. If you were moving it to the firewall that would be a huge motivator but back in the tail - I’ll pass.
