see i have that starter box, but i dont like it. i want a pullstart. i like the pullstart on my nitro 2 and my savage. i'm selling that starter box to my friend for $30 cause i used it about 10 times and he already has the batteries and chargers and I dont. his engines dont have pullstarts, so im selling it to him. thanks for the help, but im looking for a stronger pullstart for the os12. i might just sell this engine and get a new one, that's another possiblity
