I use the Dubro Kwip Klip. I have to peep through the oversized muffler passthrough hole on the cowl to guess if I bring the Kwip Klip onto the glow plug. Getting the glow connector onto the engine is not so bad when compared to getting it off when the engine starts to run. I have to kneel behind the wing, reach forward past the wing under the cowl, grab the battery with index finger & middle finger, press the release w/ my thumb. While doing this, I am on the verge of falling forward and crush the wing, worse yet, plant my face into the prop. I think I need to get myself an extra long Kwip Klip, one of the metallic purple ones...
