This is the cute little 65 HP Cosman racer seen at Apple Valley
before the race to Copper State. I asked Ron Caraway if he
was planing on putting a rotary in it and he said he did not think it
would make the three hundread miles to Copper State as it only
held 17 gallons. A 100 HP German Wankel turbo rotary burning diesel
fuel would be about right for this airplane. Perhaps not quite heavy
enough to exactly replace the Continental 65 HP that is in it
now.

In the next sentence however he was talking about a 90 HP
Continental so he would have to increase the fuel
tankage anyway.

At 12,000 ft cruise my 13B powered RV-4 does 172 mph on 6.1 gph (over 28
mpg).  I'm sure that little racer would do even better.

Yes, Yes tracy.  He's burning about 4.5 GPH and close to 190 MPH.

With a 100 HP Wankel rotary he could easily win the Everett Hatch 
prize.
