I'm using mine right out of the box with everything that comes with the ARF and it is fine. I always build slop into my elevator controls but this has all the ball links with no slop and it's fine.
The airplane really grooves well. The only thing that I would wish for is a cowl that would let you get your finger on the venturi to prime the motor rather than have to turn it over to start. But hey, if it's goopd enough for Bill Werwage (He always flips his planes over to start) I guess I can live with it.
I have about a dozen to 15 flights on mine and I have to say I'm really enjoying it.
Cheers,
Bob Lampione
