LMT 1920 big enough for Rustler or CRT 5.?

I have a real nice lehner hi amp 1940/5 turn (3100kv) motor that is perfect 0n 3s it is almost brand new (only 3 runs total) and I can't decide if I should sell it or get a crt 5 and put it in that. I ran this in a 9 pound txt-1 race truck on 3s and it had gobs of power and never got above 105 deg not even in hot weather, it runs super cool on 3s and I think it would make a perfect crt5 motor. Is the crt5 a fun basher?
