I also have a cap 232 from kyosho. I picked it up second hand (or 3rd, 4th who knows) Anyhow the guy I got it from said he flew it with a 46fx, 61fx and 91fx. He said he liked the 91 fx the best because it would rocket out of hover. I put in a .61 fx mounted at the angle given so the stock muffler will go down the center of the fuse. Look around for them, got mine for $110 NIB on this site in the marketplace.
I had to put the battery in the tail to get it to balance at the recommended 3 3/8 from the Kyosho web site even thoufh the book I got from Kyosho says 3 3/4 to 4 1/4. Is this what your book calls out? I have yet to maiden it, so I'm not sure if this CG is good. better forward then back
Also put in a 14oz tank.
Also From what I've read keep the throws low at first so I'm running on dual rates. Elevator at 5/16 up and down low at 9/16 high. Aileron 1/4 low 3/8 hi and rudder 1 1/4.
Just kinda comparing notes.
Thanks
