Microdude... it isn't just about strapping the biggest engine into the smallest airframe.
This theory doesn't work... if it did F1 racing cars would have enormous engines on them... as it happen they use completely the opposite.
Have you heard of NHRA? But comparing cars with planes is like comparing apples and oranges.

By using very large engine you're creating more problems than it worth... and to make matters worse... you could well be going faster with a far smaller engine!
Putting the YS 110 in a 46 size mustang doesn't really create problems that are not solvable, and to me its very much worth it. Also, if you can find a faster engine for the 46 size warbirds that is smaller than the YS 110 I would love to know.

You need R's... massive amounts. Two stroke pylon racing engines doing 25,000RPM spinning heavy pitch props.... now you're moving.
People who first put the YS 110 on a 46 size plane were aware of this, that is why they use a 12x10 prop (under proped) to get around 12,500 RPM on the YS 110.

Keeping thing light is the key. As is having a design that is suited to speed. That isn't a P51. Even your average, normally powered hobby p51 is going far faster (we're talking scale speed here) than a full sized version goes.
Of course keeping it light will make it faster and we know the P51D isn't the fastest airfoil, but if we wanted a fast airfoil we would have all bought pylon racers (Or even a spitfire or zero which are slightly faster when scaled down). I think you're missing my point that I want a fast warbird (Not a pylon racer, not a jet), and in particular a P51 because that is usually everyone's favorite warbird (I know it is my favorite warbird).

Over powered planes just perform plain ugly... they handle bad, perform bad and look bad...as in not good.
You need so much right thrust, extra aileron trim... so much extra ground clearence... possibly even a larger fin.
P facture, torque problems, gyroscopic effect... it all makes for a grim flying experience.
Mind you, juging by the video it doesn't look like the finer point are really your concern.
If going like stink is your thing... get a dedicated modern pylon racer and paint it to look like a P51.
The thing about a specialise pylon racer is they're build and constructed for serious structual stresses, handle beautifully and they go SOOOO fast... you'll DO yourself, so take an extra pair of underpants.
I think the plane looks fine, in fact I like the look. The head of the motor sticking out of the bottom doesn't bother me. I know warbirds don't handle as good as sport planes (Edge, Extra, etc) but that's not why I buy them. Even then I think they perform fine; the plane I fly has built in thrust compensation so torque rolling has never been an issue. Also, all of the "problems" you mentioned isn't really a problem at all or it has been fixed.
I think you have really missed the point of this thread. I wanted to know if anyone has built up a plane like the one I am proposing not if I should. That isn't to say I don't take constructive criticism, but it seems to me you're really talking out of your a55.
