Ara,
The Veco 19 BB is a great engine, it has lots of power and easy to run. Anything that a .25 will fly I can handle with ease. Lightly build is the key on Sig Twister or Banshee are really fun to fly and very competitive. I had one of the first Veco 19 BB and put that into a Green Box Nobler, I won a bunch of contests with it, the prop I used was a 10 X 4 Tornado wood Plasticoat prop. There are many props around now days so finding the best prop shouldn’t be hard.
Later,
Mikey
