On the World Model P-51 (smaller one .46/.70 size) I went to install a Cirrus 100BB retract servo which is 45mm or 1.78 inches long but the preinstalled wood mounting blocks are too close together to let the servo fit in.

Is there a shorter servo to use or do I have to struggle awkardly with trying to cut down the blocks deep in the wing?? Any suggestions on how to do this if necessary?

Did anyone else have this problem?

thanks so much for any help
