This P51 ARF is a very nice model. The quality of the ARF is a bargain for the price. A couple of areas that will need to be addressed in order to fly the model are the retract rails. The stock rails broke on my maiden flight and had to be completely reworked in order to prevent the issue from repeating. I also had a build issue with the main wing dowels, as they did not line up with the two holes in the fuse. The dowels had to be replaced/redrilled to get the wing to align with the fuse. The model flew very nice and requires specific transmitter set up to fly properly. I have my bird set up on an electric power. I highly recommend using electric retracts.
