how cold does it have to be to affect lipos and radios. I charged the batteries, and thru the plane in the car, when i got to the field it would not connect.
I came home tried in my basement. conected but had choppy movements? about five mins later everything was moving fine. its only -2c or 28f. I have a
72mhz radio

Anything electrical may be affected by cold. Some devices/connections shrink and pull away.( ESC; Servo connectors; etc. ) Might not have been the battery...might have been a connector. Though, I've read here about keeping the battery in one's pocket to keep it warm, before installing. Rich

thanks

I've had lipos that would not work well in the mid 30's (F). They'd work but not deliver good current. I warmed them up in the truck and they started working well. It is obviously a heck of lot colder up there in Canada so I can see how lipos would perform even worse.

I have had radios out for hours in temperature in the teens (ºF). The flight batteries (NiCad & NiMH) do have a tendency to loose "oomph" faster, but I believe some of that may be due to trying to move stiffer servos and control surfaces.

Don't know about the electric power aspects.

Hey, what's that white stuff all around you on the ground??

My plane an electric apprentice flew great while it was the mid 30`s outside, me? Well, I learned that gloves and TX`s don`t mix, that and I learned that if you going flying in mid 30`s weather dress warm!

I haven't had much of a problem with the electronics... but I've had problems getting my 2-stroke started. I had to put a few drops of glow in the glow plug hole to prime the engine... make sure you use a "Chicken Stick" or electic hand starter, she will kick or re-coil back, it hurts like H&ll if you try to start it by hand. It's best to run the engine a little rich on the high end as well.
