Hey FF
I saw the post in this thread that a few people got the dubro tires because the stock tires are to stiff and cause the plane to bounce on landing. So when I asked them for a replacment cowl and a set of ailerons I asked if they knew of RCU and they did so I told them about the posts in the thread about the tires and she put me on hold to check it out and when she came back she told me I would get a set of the tires sent with the cowl and ailerons
