El, the 2300 is A Super not A Thunder. I just got one in A trade A week ago, they couldn't get it running, the tank was way below the engine?? I changed that and it fired right up and is the smoothest running engine I have had in that size. I'm going to maiden the plane tomorrow so we will see how it works in the real world.
I have given away all my old TT .46 engines A while back,I just haven't used them in several years but they were every bit as good as the OS engines I had.
