Here's Jundroos P-51B Stock plane from the current line up, (maid by W.T.H Knows). Didn't know I'd be doing this untill yesterday. anyway the whole thing was rescaled to .951 the original size so that it's now accurately sized. I also reweighted it as the original had a bone dry weight of almost 11,000lbs and the real Mustang has a bone dry weight of just over 7,000. It's also been redragged as the original had every flight surface dragged at .1, and you can't actually do that in Simpleplanes. Don't worry, it keeps it's 395 mph's at 5000ft, and (presumably) has excellent high altitude performance as well. Armament reworked as the B model only got four 50's. It's external stores are stripped. so do with them what you will. I also reworked the fuel load so it caries more accurate fuel. It also now has an 11ft propeller.
