well then yeah..... that would be something to look at if its available.
Only question ---- is why does the Dago weight 1lb more (per specs) than the regular P-51

If I recall you will need a .25" muffler for the jett-stream extension to clear the cowl on the dago.
This one here has a SJ-60L and a full pipe. I think your rules will require you to stick with the jett-stream.
other photo here is a nice P-51 racer... this one is about the same size as the old House of Balsa .40 size plane, but it is about a pound lighter (and flys better). Was scratch built.
The .40 size Great Planes p-51 would indeed be a great choice too.
My personal choice if I were going to be warbird racing an ARF would be this one...

Use an 8oz bubble jett tank, Hitec 225 servos all around, nimh 700 mah battery, small 5 ch receiver. No doubt this can weigh 5 lbs when done.
Modeltec's P-51 is real nice, but just a bit on the big side... if you keep it light, it may race nice.

I do know of someone flying this with a SJ-46 in it... apparently flys well

Depends if it qualifies as "reno" or not.
for those following along, there is a thread in the jett support forum for the SJ-50 and spitfire combination
And also I saw the modeltec fun-fighters at the Toledo show... They apparently will have that available in a few different color schemes. But I dont think they are in stock yet.
