I ran this frame's V4 engine until I hit a canopy at 70 mph. I love updates. It's a bit more powerful and has enough space in the back for my Akk Fx2 Ultimate and a Hawkeye 4k split dashcam. The frame has a nice bevel and the TPU parts fit well. This banana spider weighs 455 grams and AUW 657 grams with 1300Mah 6s. I can't wait to loosen up the new color a bit. I highly recommend.
