RE: Kat 40 Dude!!
We have both the white and yellow still in stock and we are all done with vacations now so give us a yell. Orders taken in the morning are shipped that afternoon. There are literally tons of threads on engine and servo choices and setups for 40 size profiles. Do a quick run down the threads or search and you will find loads of info. Any reliable 2-stroke .46 BB or better or 63-72 4-stroke will rocket these planes.
