The only issue with the 9150's is that they are an odd shape. Many of those planes have the aileron holes already cut and the 9150 is not very deep, but it is very wide, so you may have to make some major modifications, not just slightly enlarging the hole. They were designed for thin wings and it is best if the plane is designed for them. They would certainly work, but would take more work to make them fit most likely. I ran them, and the 9154 (same servo, different gear ratio to make them faster) for years in my Black Magic.
