Generally small engines, pretty much anything under .09 aren't fun to start with standard starters, in fact the amount of times I've seen 049's ripped from planes with starters makes me not do it at all. The starter cone is too big, and the rpm is a bit low for small stuff.
Sullivan did do a Hornet 1/2A starter, as did Lite Machines, but finding one these days is hard work. I have the Lite Machines one and it's great for 049 powered combat!
If i were to buy another starter (I've had about 8, but never purchased one, always seem to get them in job lots) I'd probably go for one of the geared ones, as they're lighter and have more torque.
