The Brison 2.4 work well in the Kange Texas Hurricane ARF 78" span and its looks allmost like a Edge 540 and a very stable flyer. I have had one with the fFPE 2.4 both with fixed ign and the updated sycrospark . The updated version fpe flys it ok but the Brison is still a little stronger. My current Hurricane has a Brison 3.2 on it and its awesome.The Hurricane is a top notch ARF and very easy to assemble.
