This is a really great frame. Especially in this price range. Sophisticated, solid construction. Enough space for a full 20x20 tower or you can split the vtx in the back. Designed for 30x30 but suitable for both. It flies great paired with hglrc f435 and gep 2306.5 2450kv motors. The entire assembly costs less than $150 and this thing snaps. Would I buy again and will most likely buy again. Probably the best freestyle frame I've ever bought.
