I'm new to glow engines and have tried two different Hot Shot 2 glow plug heaters on my first glow engine a YS 110. Frequently both glow heaters would shake off of the plug before I could get it taken off. Now the second one will no longer attached to the plug. Note that the engine is mounted horizontally, and that I've only been running this engine for one week.

My question is what glow plug heater do you suggest that I get?

Is there a glow heater that uses a LiPo and attaches with a wire rather than having all of that battery weight hanging off of an angry engine? (I like LiPo batteries.)

PS I have a YS63 coming in the mail and will use the same glow heater with that engine also.

Thanks, Glover
