If you're looking to fly RC combat in the US, then it pays to look at what the guys at the top are doing. It's no accident.

You don't see anyone using NovaRossi's.

Lou and Tenman are right on.

Cost matters. Espeically in an event where engines sometimes get filled with dirt or have carbs sheared off or worse. Breaking engines isn't common (or none of us would be able to afford this for long), but it can and does happen.

You're welcome to come fly with whatever engine you want, and show us that it's a competitive engine.

Right now, the Webra is king of the pile. The OS is probably the best engine for someone new to combat since it's certainly competitive and it's the easiest engine to set up and get good power from in the air.

If you want to be competitive, you can't afford to have an engine that won't run consistantly, that's for sure.

Also, a lot of those engines designed to turn really small props at high RPM need bladder fuel systems. I personally think bladders are too much trouble, and not worth the learning curve and frustration that everyone seems to go through before getting good with them. If you've been flying CL for years, and already know bladders, then it's not a problem. Or, if you live in an area where there are guys running bladders who can help you out, then that will shorten the learning curve. Otherwise, keeping it simple is the way to go.

The OS and the Webra are competitive on a basic clunk tank, doing things exactly the way guys learn how to do their engines on their basic trainers.

Thrash, so, how many rounds of RC combat have you put on your NovaRossi engines in the last couple of years? How many do you have? and I don't think I know you from Nats or other big events, or am I mistaken?
