I have been flying my park flyers out here in the Chicagoland and having fun flying with frozen fingers. The temp 22 to 30 degrees and they batteries are a bit warmer. What would be the coldest you can fly before it would affect the LiPo and servos?

Hey Burner - I've been thinking it's the new FPV gear that eats the battery on my EasyStar II. My flight times went from 25-30 minutes late summer to 12 minutes or so in December and January, flying between 0 and -10 degrees F. I was sure it was the Vtx. Yesterday the temp was up to 28, and I had it up for 19 minutes, so I guess the problem has been the cold. That's with a 3S 2200mah Turnigy battery. My servos work fine down to -10, but fingers start to suffer! My greatest worry in the cold is cracking the insulation on the wiring. I change batteries in the car when I can, and move the wires as little as possible. I've had to replace an aileron servo wire and the video cable for my DVR, but the connections to the batteries have held up.

Did u notice batteries warmer after flight? It hard to tell if they warmer or my hand just frozen and it feels hot. Just worried about burning out batteries. I know the ESC loves the cold weather. Can't find anything in manuals.

I'm gaining confidence with FPV. Yesterday I flew my EasyStarII 873 feet up and 3400 feet away - max up and sideways for me so far! That's with a 600mw 5.8ghz Immersion Vtx, Fatshark Predator glasses, Spironet antennas, Dx6i controller, Ar6115 rx and DORA for RSSI. I had solid video except when the plane passed directly overhead.
I could have flown higher, but I was getting RSSI glitches at a distance of around 3000'. I don't think the Dx6i will reach much further without an antenna upgrade. I have a 7db patch antenna to stick on the controller.

Nice day. I messed around on the UM t28 for warm up, then I put the UMX stryker through some aeros: Snap rolls, harriers, and inverted flat spins.
Then I FINALLY maidened the PZ F4U-A1 . I like it. Its not as fast as I thought it would be, but it's not too slow either. Definitely more aerobatic then I thought, so I flicked to low rates. One thing that's annoying about it is that it really needs prop wash. The tail surfaces barely respond with the motor off, and it slows down pretty quick. All in all, it flies nice, like you would expect with a PZ model. It doesn't do that weird tail-dragging thing that some corsairs do on aileron-only turns.I managed to nose it over on the landing One of the drop tanks came off. Oh well,YOLO . A little epoxy and It will be good as new
