I Have theis Velox RevII .60 Its a really good flyer I had os .61 Fx in It But it just isnt doing what i want it to do I need more power. Now im NOT looking to make a fighter jet outta my velox but I need help picking out an engine for it. What do YOU think would be the best motor for it.

Is the plane you have the one on this page?

If so, a .75 or .91 two stroke engine should give a power boost over the 61FX. If that's not the plane, can you post a link to the plane you have?

You mention "im looking to make a fighter jet out of my velox." If the plane is the one on the link, and you literally mean you want to put a jet engine on it; you have a ton of work in front of you. I don't know how to do it, but I guess anything "can" be done.

at 8lbs.... something like an OS 1.08 or a YS 1.10 would be nice

LOL!!!!!!!! Im sorry it was a mistake in grammar i meant dont want to make a fighter jet out of it but i do want a bigger power boost.

A 75 or 90 sized 2 stroke will give you a power boost without a wieght gain. You could go with the OS 90. I really like the super tigre 90 for the price. Check in the marketplace here you can always find great deals on good used engines.
