I have recently purchased one of my old giant stingers w/G62 from a friend, This plane is 7yrs old with a lot of time on it! The engine runs fine but I forgot how much it hammers at low idle.I will fly it this season with the magneto but I would like to put a synchro spark on it. Why are the ign for the zenoahs only $124.95? do they use some of the parts already there? Is the ign from rcign comparable? I am a toolmaker so if I can save some money by making a few of the parts let me know.
