Matt,

Hopefully someone can back me up here, but the connector on these batteries ( http://www.hobbypartz.com/83p-2200mah-4s1p-148-20c.html ) looks like the Thunder Power adapters. I only have FMA CellPro LiPo's right now, but have the TP adapters and as best I can tell it looks like that is what these batteries have. I just ordered a couple of the blue LiPo's like Matt from HobbyKing. However, once my PayPal cleared I got an e-mail from them saying my order may take up to 45 (yes, Forty-Five) days to arrive. []

I know the HobbyKing people always reply to my e-mails quickly (they're 12 hours ahead of us), so I'm sure HobbyPartz guys would too.

Hopefully the industry can settle on one stinkin' balance connector soon, but I doubt it. Until then, you just gotta have a fist full of adapters. . .

Did you get or have access to a Watt meter? Personally, I'm a big fan of the Eagle Tree system. The data logger is the size of a small receiver and you can take it up for a flight then download it to your laptop and see what your system is doing in the air. There is also a small LCD "screen" for ground use without a laptop. Also, you can use it on your wet airplanes for all kinds of stuff like in-flight RPM, cylinder head temperature, servo amp draw, ect.
