What prop do you use for flite streak with a Fox .25

Thanks, Scott

Do you have any idea of what takeoff revs you have?  I was running a 9-6 and probably leaned out more than it should be - lap times were way too fast.  This motor is much more than the worn out McCoy .29 I had on it.

Theres in fact TWo versions of the 25 , one from the 80s , maybe with the black prop driver , has wider crank timing , like the 1/4 thread shaft 19 .
silly picture . Needle @ 6 or 7 turns , according to fuel .

nuther silly picture Empasiseing NOSE DOUBLERS , this in fact runs prettty smooth . Setting props @ 90 deg. to Ea Other @ TDC .
knactually OSes in er in this shot , but the FOX 19 / 25s 'r going back in . Silly Me has Just Bought ANOTHER , youd think TEN would be enough .


You can here em whistling around HERE . and spot the W Wind ,

Id axidently put some fuel in the nitro , Had to sprint for spanner & screwdiver to refix a prop kicked loose , on W wid , last up .
Definately 15 or 20 % Nitro on something like these gets easier settings , thus better air time .

The Piston Liner is unhardened Leaded Steel , Ive always used 27 % Oil in them .

The 25s I have WILL actually ' switch ' like up & down . Ive some old High A R 10 x 4 woods they like ,
or top flight 8 x 6s or 9 x 4s , Taipan 9x4s , but the Zinger 9 x 5s are as good .
