RE: Top Flite 1/7 P-51 Build
Looking real sweet there JohnnyEm. Are you flying off pavement or grass with yours? I have the ARF, (I know this is the kit thread) but basically the same airplane. Will be following to see how your maiden goes.
I had Century retracts on mine for about 50 flights, flying off grass. Unfortunate pilot error combined with hitting the grass right where a gopher had apparently been digging caused me to have to re-wing mine. Ripped one gear almost completely off and the other was bent pretty bad.
I had done some massive reinforcing of the gear mount area and had to re-do my struts several times over the year and a half, but it was generally a great bird. Actually just finishing up the new wing, getting ready to re-maiden.
Best of luck with your new 'Stang. It is beautiful!!
