I have seen theworldmodels gs p-51 fly with the 2300. It weights the same as the hangar 9 p-51 so the 2300 should fly it very well. Also I have seen a top flight staggering fly in nashville tn with a 2300 and it weighed about 18 lbs and it flew but bairly. Yeah the 35 will fly it just fine but the 2300 will fly it well. Thanks for the concern though.
