The add on Craigslist says he has A4's and A6's as well... We bought the A5's brand new for $325.00 cash....
By the way, I was wrong on the gear ration... it is 1.95:1 not 1:1.95... Same is true of the 1.78:1 vs 1:1.78... another reason we picked up the A5's... 1.95 reves of the engine = 1 rev of the propellers.
It appears that we will have a set of C3's to sell.
