Ok, I have asked everyone I know, and they have all said that they do not exist in that scale.
I'm guessing you're dealing with an R/C kit of some sort. pushing 3 feet long or so?
Best advice I got was to use a set of 1/32 scale and blow them up and have them re-done.
I think at this scale, the best way is to do some masking job the result would be much better... It depends on which you want to do though because some of tail arts could be problematic... But nothing undoable !
