Luckily to get three free Tattu R-line 4s 95c Lipo battery, and I then I test it for my Walkera F210. The Tattu R-Line 4s 1300mAh batteryperformed very well, punch-outs are even more impressive than with stock battery. I could say that also flight time was better, but this could be hardly determined because every flight is different. Full throttle drains the LiPo battery much faster than just hovering.
I have wrote a review and post on these two blog, if you are interesting in it, you can check on:
