Agreed VG. The first couple gas engines I played with several years ago were first bench run for familiarity purposes. Gas was new to me after decades of glow.. Now typical carb settings are made from the start and the engines are run in in the air .
I have heeded the advice of the few that really know their stuff and have run these at near final needles from the start. The engines broke in fine and work great.. BT W gas engines last better than some glow do, with much less maintenance.

On interference, I have used both 2.4 gig and 72 meg radios and have had no issues. Then again I have used the Tech Aero IBEC from the start. The RFI filtering of this goodie works great
