The engine is fine. Maybe I put the satellite to far away putting some tenchion on the plug. Oh well SH** happens. Already mounting the X45 into a Weston Magnum R. Having to make a new canopy section to cowl in the pipe for the rear exhaust ST x45. The Demon was very fast had 2 full throttle passes. It was passing a electric s400 like it was standing still and that plane has been clocked at 142. The 2.4 stuff is still a better system them my 72 was at our field. Whould the satellite coming unplugged cause the loss of signal??
