The FX.46 does weight 4oz more than the LA.46 Hope that's not a problem ?

Anyway, I will still have to start contruction, so I'm not flying it for the next couple of weeks.

Please keep me posted on any experience with the FX.46

I currently have one in my Easy Sport, I could always try it, but I don't like to swap/build over engines

Is a 11x5 of 12x4 prop not better for vertical performance compared to the 11x7 ? I was always told that higher pitch increased top speed at level flight, but lower pitch increased thrust (in vertical or manouvers)
