This is my first 5 inch racer. Flys really nice with the HQ 5x4.8x3s. Hoping to upgrade the vtx but the eachine one is holding up quite nicely for 11$. The Fire 2300kv motors are quite power hungry and if you are wanting to run a 5050+ propeller you may need to upgrade the esc's. However I only use the HQ 5x4.8x3s so those propellers are fine. Overall this build is quite a speed monster. I do use this for some freestyle fpv but it is more race focused. Also go check out my youtube channel i've got some dvr up there link below. For a quad using some higher pitched props it runs super effiecient. *UPDATE** I've been doing some freestyle and comparing it to some other quads and it preforms great as a racer and as a freestyler.
