Thanks for the input. The reason I'm trying to save a buck is I'm retired on a small pension plus Soc. Sec. Just started RC this past spring, so I don't have much in the way of supplies or experience. I was very active in control line in the 50s, 60s, and 70s, but things are a little different now.

I am buying the DC3 from av8r4aa here on RCU and now I need the engines. I have decided that 4 stroke would be the way to go. I don't think I can really afford a new OS 52 or Saito 50, and the used ones I see are hardly less than new. I found the new HP VT 49s for $130.00 each. That's $50.00 bucks an engine less.

Anyone else have any experience with these engines? How about other makes?

Again, thanks for the input. I can use all the help I can get.
