Ever found that your plane hits the ceiling under high power or that it does not reach it at all? That is because you do not have the correct motor size. For example, if your plane hits the ceiling you should use a motor with reduced width. This is possible now with our new Competition Motor Pack. It features 50 feet of each of the following motor sizes: .079″, .086″, .093″ (3.32″), .101″, .108″. This package has been put together at the request of many competitors who want to get the maximum out of their aircraft. How do you do that? You need to match the motor to your aircraft and to the ceiling. That is virtually impossible with only one size rubber. This is why we brought out this package complete with instructions.
