BM,

1) The RR Merlin engined P-51 (B, C, D & K) belly scoop slopes up at about 45 degrees. Still, these details just don't matter when it comes to belly landing because the plane will land fine. Really.

2) The Herr kit isn't with 10% of 1/12th scale. It has many errors in its shape. Check it against a good 3-view for specific problems.

3) DO NOT use any kit's plans for reference. Most kit's plans are NOT accurate because designers tend to make concessions that ease building and/or manufacture. If you are refering to the GP .40 size P-51, it is a "fun scale" design that isn't very scale at all.

There are ACCURATE 3-views availble from numerous sources, including here:

Please, if you intend to build a plane for Combat, do NOT build it from balsa because it will splatter before you have a chance to have any fun with it. If you can scrape together $36 (plus the shipping), I highly recommend the JK Aerotech P-51 kit. Do a search here for "JKA" and read through what has already been posted about them.

Watch_ur_6,
The streamer starts out 30' long and all one piece. The streamers you saw on wings and tails were cut from other planes.
