PT-19
JWN,
I have three of kyosho's warbirds excluding the PT-19 but sill I would venture to say you'll have no problems with your model.
Duke is the guy that posts from time to time on the Kyosho PT-19, do a search for his posts.
To my knowlegde there have been no discrepencies in terms of the instructions, balance point and control surface travel are as written.
