I'm going to disagree with you here Tigerdude. First of all, if you put a small dab of epoxy on the back of the blindnut it will not fall out of the backside of the firewall. To say that screws are stronger isn't looking at the whole system. With a screw you have a just the threads to transfer the power of the engine to the fuselage. But with a blind nut you have a larger surface area with the back of the blind in contact with the firewall to transfer that power to the fuselage. And lastly the threads that you have cut in the wood are nowhere near as strong as havign the metal threads of a blindnut. On a smaller engine like you are using on this plane it might not make too much of a difference, but when you get to bigger engines it's a bad practice as they can pull the threads out of the wood without even trying.
