Yes, so by stretching out the fuselage to the correct width you have the edges of the spinners exactly at the edge of the wonky bit.

Could you save the last of the polygons and make a night fighter variant? A bit more interesting than the typical P-38.

It only needs the S's on the inner H-stab surfaces to be complete.

How do you make a plane slip when it turns, like drifting?

Why do you compare flying a plane with.... drifting..... a car I presume, I think what you might be referring to is the fact that a P-38 will sag its tail if you don`t input some rudder while in a banking turn
A 109 shooting a P-51 is wrong...

Brields, It has to do with authority. Generally the larger P-38s that I have seen have airfoiled h-stabs and the V-stabs and rudder seem to be just tapered flat stabs. This gives very good pitch control but yaw control requires more work. Coordinating the rudder in turns. Going back to your car analogy its like oversteer. The turns are very wide without power control or in this case rudder control. Another factor playing into this is making sure the airfoils are right for the booms. Its tricky though because looking at the booms side-on its basically an inverted flat-bottomed airfoil. Something that does not really work well in the physics setup. The competing forces of the wings lift and the minor fuselage (booms) counter lift create a wash over the tail that also contributes to the effect. Then you have the area of v-stab in relation to the wings and such. Remember, air does not scale. These fighters were designed to be as minimal as possible full-scale. Keeping the scale lines on a model means you are bound to get inefficiencies.

Case-in-point. Boof's goon. I made a model from the same 3-views he used. I had to enlarge the rudder to 140% of the scale size to get good stability. Its not great but its much more manageable. It did not have good control at low speeds and even the at high speeds I had to do a lot of work to counter the torque. With the enlarged tail, I still have a slight mix with throttle and rudder but the low-speed handling is totally comfortable so I can land it in one piece.

Thanks for all the help and suggestions.

The P-38 has been POSTED

I tried my best, tweak the settings if you don't like it. I am looong overdue to move on to something else.

This P-38 is AWESOME! I was going to make one myself--almost started it actually, but thankfully Chris told me you made this one and BAM! I am flying it now. Everything looks and works perfectly on this model other than one detail. The model doesn't split in half the moment the wheels touch the air just above the runway....Oh wait, that's isn't supposed to happen like another P-38 model I know of. Yours works perfectly oneder. I love the landings too. Thanks for making me not have to model this one.

Maybe I'll do a P-61 to compliment your model. It just might take a year or three to get it done. LOL.

Thanks Matt, it could have been better actually. I had a lot of polys left over but I chickened out and posted it kind of prematurely when I started having trouble with the editor, I was afraid I might lose some of the work.

There was one problem. Something the P-38 was (in)famous for. the two engines
turned in opposite directions to lesson the P-factor effect.

nothing a simple AV can't fix.
