If I can actually pull off the dual flight, without killing my birds or myself, I will figure out a way to video it for sure.
Ok, see, you have to video that either way. Now I don't want you getting hurt and trust you'll be as careful as possible so no excuses!
I've ordered from AEO. Their pricing is terrible unless you buy in significant quantities. I had to buy 3x of each item just to get a somewhat reasonable rate. Things didn't go perfectly but in all fairness they sent their stuff out as promised. The only thing is their instructions were wrong and I had a lot of grief trying to program their ESC. That said, the AEO ESC works perfectly now. I had ordered a couple of turnigys when I got frustrated with the AEO's but I haven't even touched the turnigys yet so I can't say which one is better. If there were enough parties interested I'd consider ordering a few to split out.

Regarding the 2200mah lipo that's the same size as the stock battery, the first test was interesting. It is indeed a li-polymer battery. However, throttle response was very poor. The battery dropped voltage quickly as shown by on-board meter. It became extremely hot after 4 minutes and critical voltage was reached. For comparison, after the motors cooled completely, I ran the chopper with the nanotech 2000mah. It showed the usual quick throttle response and ran well for the normal 8 minutes at which point I stopped. The voltage was still 7.5. Battery not even warm. Will test a couple more times, but so far not impressed. May be a bad battery or possibly it just can't handle the amp load.
Your results would seem to make sense. The nano-tech seems exceptional for size and performance combined and it's already bigger than the stock battery at 2000mah 7.4v. To get the small size they probably had to sacrifice whatever it is that makes it possible to have a high current rating. I've had pretty good luck so far. I've ordered from a few unknown brands and the only batteries that failed completely were the walkeras I ordered for my chinooks. I thought I was ripped off when a 900mah 11.1v I ordered over 2 months ago (ebay) never arrived. I was about to get a refund when it finally showed up today. I immediately threw it on the charger and noticed one cell was jumping around like crazy so I thought it was a junk. I let it charge until I got an error on it, then let it sit for awhile. When I went back and reconnected it to the charger, the cells had balanced out and it charged fully. I connected it to the F45 and did a low-stress test. I fired it up at about 30% throttle (with weights to keep the heli from moving) and jigged the remote so the tail would stop. I let it run for about 8 minutes. When I hooked it back to the charger the voltage was good and it has since finished charging right up to 4.20 on each cell. In the test I ramped up the rotors to max for awhile and it didn't get significantly hot and there was reasonable power. It's quite a small battery compared to the 1000mah I have. Anyway, I think it's actually too small for my F45 so I might use it for lights on a heli pad or something.
We are all so damned addicted to this!
