Hobbypark Glow Plug Igniter for Nitro RC Engines - AA Battery Powered Starter Tool for RC Cars, Buggies, Trucks & Model Airplanes | Perfect for Nitro Engine Starting, Maintenance & Racing Scenarios

Here's the key: get yourself a pack of AA NiMH rechargeable batteries, preferably 2000mAh or higher capacity. Keep them charged and in your field box. Change them out as they run down. Unless you're killing batteries in your futile attempt at getting a glow engine to run due to inexperience or ineptitude, this thing works great.But honestly, I don't know why you'd need to change batteries much at all. I don't understand how folks can't get it to work at all, or can't get it to last more than a few times. I rarely have to swap batteries for a day at the flying field, and it's absolutely painless to do so. This one makes better contact than my GP ignitor, lasts longer with a good rechargeable AA, and is smaller and easier to use/keep in a pocket.
