Got it finished and flying this weekend. Had 4 flights with it yesterday, even managed a p19 with it on the last flight.
Very pleased with it so far, bit of work to do with it re rudder trim but apart from that its great.
As with most biplanes, rudder is very powerful making rollers and ke manoeuvres a lot more stable and easier to control. Problem is the powerful rudder control it amplifies any unwanted yaw trim.
It was very calm aswell so will be interesting to see how it performs in the wind.
