The jive is smaller and shock resistant and with an extra heatsink which i have fitted doubles the continous current rating and it has a built in 5A BEC. Dont know how reliable it is yet but i have got the old controller as a spare which is held together by glue, tape and cable ties now as it got too hot and melted the heatshrink off which held it together and the heatsinks fell off but it still works just.
