It's a FX.

My fuel is SIG 20% oil (50% castor-50%syn) 10% nitro

I will try the pinch test.

When I advance the throttle it puts out smoke. (Dolsen, typing in all caps is considered yelling)

I know it's not the delay in sound because I can float the plane in like I'm going to land it and then hit the throttle when the plane is right in front of me.

Thanks for the help guys. I'm not intimidated when it comes to tinkering with it, just do not want to burn up my engine. I broke it in and it has about 10 flights on it. Would because it's still new be the reason for this?
