You can get the hirobo auto starter from couple of websites
www.ehirobo.com
www.rchover.com
just type in the web search (hirobo auto start) and yo will find it
i used it in my hirobo golden cobra
but after i couple of flight i decided to converted into free smoke heli...so, im now in the process, i bouught already the conversion kit for it along with the bruchless motor and its ESC
Im sure it will be such a nice change
i started to get really board from pumping fuel, cleaning after each flight.
