I use an Onboard glow system on my 2 stroke on my Showtime.. but I didn;t mount inverted.. I just put it upright like a trainer.. Honestly I like the look of the big cyclinder out the top of the cowl. Just my preference but the engine runs great upright.. even better withonboard glow.. never deadsticked it and it flies beautifully. Besides, it's not a scale plane... so no need for a scale engine right.
