Not helicopter related but I will give the Turnigy Nano-Tech batteries a HUGE Thumbs up!
I have an EDF Art Tech Eurofighter and have been flying it with Turnigy 1300 Mah and 1800 Mah 3S batteries...
The 1300 mah would give me 250 Watts initially, dropping to 200 after 2 minutes - They were nice and light and the aircraft flew very well and was manouverable. A loop from level flight is JUST barely possible.
The 1800 mah gave 320 watts initially, dropping to around 240 after 2 minutes - They were heavier and required a greater take off roll and the fwd cg made the aircraft very stable but less manouverable.. a loop from level flight is impossible.
Today my order of 3 x 1300 mah and 2 x 1600 mah Turnigy Nano-techs arrived.
The nano 1300s gave me 300 watts initially, dropping to 240 afer 2 mins (a big improvement over the standard Turnigy 1300) and they are lighter and smaller to boot.
The nano 1600s gave me 350 watts initially, dropping to 280 after 2 mins.. again a big improvement on the std 1800s and they are 20 grams lighter.
I then flew both.. the 1300's were awesome, the Eurofighter took off in half the normal distance on grass and climbed out at a 45 degree angle (I get around 20 degrees on standard 1300's)
It was faster and was able to sustain multiple loops from level flight - a huge improvement
The nano 1600s again were awesome - the Euro took off very well and climbed at around 60 degrees - They were light enough to give me much better manouverablity that the std 1800s. and I beleive are the ideal battery for this plane... I have been flying it almost daily for a month but today was by FAR the most enjoyable the Euro has been for me..
I immediately ordered all Hobbykings remaining stock of 1600 nano tech batteries (only 4 at the time...)
Hope this helps.. but I will only be ordering nanos in the future.. they can be charged at 5C to boot.. My chargers can't do that, but I can charge them in 20 minutes, compared to an hour for the std turnigys...
As I said, they get a HUGE Thumbs up from me.
