LOL, yep-they sure are monsters!
I do have the Special Hobby version, and hope to get to it soon. I had hoped to build it this year, but all of the current GB's have ruled that out.
On your spinner, will the P-51 spinner be large enough in diameter? The one on that racer looks a lot larger. I am not dure about any other spinners, guess you might be able to measure what you need in diamter and post in aircraft if any one has one that size. Just a thought...
Funny lil' side note...
If you look VERY closely to the photo I posted, there is a tiny sticker on the starboard inner gear door that reads "RIFF RAFF 99". Not sure if it is a joke or not, but thought it was pretty funny myself.
