Looks like it's time for you to get an Avistar with a 46 LX engine.

I was wondering, Is this the same plane engine combo that you claimed (on another thread) was capable of speeds reaching 150MPH ?????
I found the following statement in the ARF RTF Forum
There are few Avistar planes pushing close to 150 MPH with the 46 LX BB engine and giving planes that cost a $1,000.00 or mre a good run for the money.
