New S4 Ethix Lemon Lime Propellers 5037 from the Mr Steele Camp and manufactured by HQProp.
A very popular prop for fpv freestyle flying in easy to see colours for the added bling factor. 

The S4 props are designed for freestyle fpv pilots who want a little bit more instant punch than the S3 with a slightly steeper pitch they offer slightly quicker response. Ethix is a brand that not only supports the FPV community by releasing great and innovative products at affordable prices but some of the proceeds make it back to the pilots that design these.
And the colours of the props are nice and juicy just like lemon and lime :)
