The sirocco 500e looks pretty bloody good

 

This story reminds me another one Velos 880.

Best advice... be patient.

Same story with Protos Max. Delay was counted in months.

My colleague flying Scirocco 550 told me it is the best 550. He was flying Gaui X5 also and prefered Scirocco.

 

IMO it looks very similar to a TREX type build with the torque tube, the main drive, the tail case and tail box and even battery position. So it probably would fly similar. It would be interesting to know the weight, build quality, how the battery attaches and how it compares with cost to a TREX in both purchase and spares.
