If you mean a Thunder Tiger .46? Or any other .46 for that matter, a 1/12 scale GP combat plane would be rediculously overpowered and nose heavy. I'm thinking virtually unflyable. Should look pretty scary though. Be sure to brandish it menacingly when you go to the field. If you're brave enough to test fly I'm betting you get one very short, but highly entertaining go round with a distinct sound at the end, SPLAT!
If you're serious about gearing up a combat plane for competition, remember the class engine size limits that are applicable.
2610 used to be a .26 size engine but a recent stupid (IMHO) rules change increased that to .30. I don't know when the change takes effect and frankly don't care. The class was already way too fast in most people's estimation and more horsepower should just about finish the job of killing it off.
2548 requires a .25 size motor which is plenty of zip for that size plane.
If you're not serious, go for it, have fun, just be careful and make sure no one puts an eye out! Good luck!

I can tell you why .30 was decided upon originally (I was on the rules commitee that created the initial Open class rules with the RCCA) There were several engines on the market at the time that were of the .28 displacement and they wanted to allow these. None of them were powerful though and have since fallen by the way side. Also the classes are a throwback to the original engine designations of 1\2 A, A, B, C, and D. That is why the open classes are designated that way. No real airframe rules just an engine size limit.
As for the .46...... Why? Is this all you have lying around? Just go buy a bigger plane. You will have to add a bunch of weight to the tail to get it to balance and it will be snap happy. One thing we found early on, it is best to keep the small scale birds light.
If you do decide to do it, get a video because I want to see it. I love to see dramatic, catastrophic crashes at other peoples expense!

RE: GP P51 25size with a 46TT
I built one with an OS.46la once...
Yeah...it was heavy,I had to put the elevator servo back to the tail!
Hand launches were almost impossible...a plane that heavy wants to drop & tork over with even
the best of hand launchs!
But I did manage to get it going & flying a few times...
yeah it was fast...
burned thru the fuel rather quick...
And when it runs out of fuel...it drops like a rock!
I recently sold it...the hand launching was just a bit too much...even for me!
Good Luck
