I got one of these on a 1/4 scale TaylorCraft......it is top-shelf ! Very well worth the conversion. I am running mine on C-H and using Syncro-Spark. I have changed the carb set-up since this pic was taken. I made a twister intake "model" from a wooden block and sent it to Ralph Cunningham @ R C Ignitions. This allowed the linkage to be easy to alighn with the firewall. Ralph is the best !
