Spaceclam

i am an owner of a .91 four stroke engine. i am looking for the BEST 14x6 prop that is available, below $30. i am looking for thrust. noise is tolorable. i would also prefer less vibration, but it is not necessary

It's obvious that you are willing to spend more money on props than I am...hmmm...

I prefer APC ($12) and B-Y&O ($8) The B-Y&O is a wooden prop available from www.brodak.com

Of course there are the exotic brands, too...buy'em if you wonna.

Graupner!

Depends on your application. Speed? Pattern? Scale? Sport?

I like APC as a general sport prop.

Spaceclam

unlimited vertical. here is why i am specifying 14x6: i can't go lower than that because my plane is rather heavy, and won't fly at those low speeds. plus, even if it didn't, i would look really stupid putt-puttin by at 20 mph. where would i find a graupner prop? i already have an apc on order.

I think Graupner and APC make great props. But it really depends on your application.

What you want is a Graupner 13.5 x 8 They are outstanding on a 91 4-stroke, and will suit your Cap very well. (and under 10 bucks)

Check out the bolly clubman 13.5 x 8 It has a swept tip similar to the apc but not as sharp.
If wood is OK try a zinger pro 14 x 6

where would i find boly props? carbon fiber may be the answer. do any ofyou guiys know where to find a good carbon fiber prop?

Not sure they make CF props that small. 18-6 is the smallest Ive run across in mejlik
I dont think that is what you want for a 91 anyway. CF props are usually a bit heavier and no prop on a 8+ lb plane with a 4 stroke 91 is going to turn it into a hovering machine
I have a 60 size Kaos that weighs about 7.75 lbs. It has good speed and very good vertical with the bolly clubman, but not unlimited with a saito 91

They carry Bolly, Mejzlik, Menz & Air Models props. However most of these manufactures cater to larger sizes.

i just got my apc 14x6. it worked jsut as well as the master airscrew, but not better. in that case, i will stick with the ma prop tdo i don't have to modify my spinner.

I've got four planes with 91 four strokes. Two TF warbirds one 10.5 lbs one 11.5 lbs both fly well with Graupner 14-7 props. A Citabria @ 9 lbs flys with a APC 14-6. A CAP232 @ 8 LBS. with an APC 15-4W. Very good vertical, the W is for wide, not the thin sharp typical APC it actually resembles the Graupners.

every prop has its advantage. wood is better for your engine and has less sound. I use the master airscrew props for my trainer
