I carry one when I run my weed wacker and leaf blower cant be too safe lol. You will love going gas but one tidbit of info I had a good 25cc converted gas engine on a 25% cub it put out 8 lbs of thrust (weeeeek!) I took it off and put ona Zenoah G26 went to 15lbs of thrust, almost twice the power. I guess you get what you pay for.
