I'm finally getting ready to assemble rx-7 to go into my w8 tailwind. Would
like to use my existing motor mount and gear legs with modifications to use
rx-7. This would mean a 60" diameter prop. I've been flying this prop/90 hp
cont. combo for 40 years. I really hesitate to increase gear length because
of the excellent results I have had in the past.

Please sign me up for  acre .

Thank You,

Wow a 60 inch prop should turn 8000 engine RPM for take off using a 2.85:1
gear box. With a p-port that would be close to 275 HP. Quite spectacular.

Obviously you want to detune the engine or use a 2.17:1 gear box.
