I have never used Hyps as yet, only 300 Nano's and the 200 E-flites, and have only been flying my Mcpx since mid-july, now 2 Bl and 1 stock, but even with my limited experience, I could feel the punch and lightness of these Batts and just received 7 more.
Excellent service and communication by PRC!
I have used Nanoteh and Hyperion and there is no comparison to the power I receive from these batteries throughout the entire flight.
Best part is that these batteries fit in the stock tray and have the stock connector on them. They are a bit snug in the tray and can be difficult to insert the first few times, but they do not slide around during piro flips and did I mention the power?
Thanks for the great product and fast shipping, David!
