Ya it’s a nice option when starting. But my old school attitude,I know it’s a virus. I shy away from using a starter, oh I have one, but it collects dust mostly. And as far as battery clips go, I use the old style clips, and a small clip for the plug and use heat shrink to protect from shorting out if it hits the head, instant plug burn up. I use a power reducer to one point five volt. To start my Fox Stunt engines. I was test running my 59 I plan on using it in my project Flying Fool 45. It spit fuel in my left eye, caused an infection, now I use shop glasses to protect my eyes. Don’t know why my 59 spits fuel out of the Venturi. My 35 Stunt engines don’t do that. The 59 is the First slant plug engine I own. I got a three inch spinner for that 45 Fool really looks nice when installed. Aluminum spinner, plan on a 12/4 to 8 prop, bought one of each all maple props. Have to do some testing if and when I get to fly. Not this year but possibly next year. See how my Back does? Hey guys keep them lines tite! AJ
