amax on odonalds race fuel has both costor oil and synthetic oil in it.. mark is so far back loged it would be amonth before i get the 1440 prop[&o].. trying to find out what other props will work on it.
I've got about 6 or 7hrs in on testing props....
Here's what I've been able to pull well besides the 1440:
Prather 215 (just sharpened & balanced);
Octura 1640 reduced to 36mm (3.0 cup);
Voodoo Props SS 39.9x21 (just sharpened & balanced)
GrimRacer 40x53 (37.8mm barr cut 3.1 cup).
My setup is a 3 port NR (@1.5 tanks thru it); MACS 2.5 pipe set @6 3/8"; total weight RTR 2lbs 12oz. Interestingly, since Rod opened up my carb to @.280, I can pull more prop than my 2 1/4 lb boat I ran last year (the carb was .254 bore).
