You didn't say if it was the 46 or the 60 size? I have a 91fs on my 46 size and it climbs out at half throttle (15x4 prop). I think you will have no problems with either plane with the 91 fs.....

hi,

well sorry i forgot to mention that its a 60 size,but i heard that they are using on the os 91 fs a 14x4W prop,is it a good size?or i should get the 15x4?
by the way what kind of fuel are u using on ur engine?
i have the four stroke cool power,and i have the 25%cool power!

thanks[&:]

I have video of U-Can-Do on my website .. it is electric powered and is still capable of doing prop hanging and most other 3D moves ... have a nose in the gallery on page 6 its here >> www.rcfun.co.uk Please feel free to add comments in the forum ...
You are going to have soooo much fun with that plane ;) enjoy.

RE: u can do 3d
 

I run 15% with 18% castor/syn oil. Mine does well with the 15x4 prop but the plane is slightly lighter and smaller so may not be as good on the 60 size. Try a 14x6 also and compare. I use zinger wood props as they are lighter, cheaper and perform well for my purposes.
You should have a lot of enjoyment from this combo......

hi,

what about the 14x4W APC,is it a small prop on the 91 fs?

thank u

RE: u can do 3d
 

Zingers are extremely inefficient. You can gain a lot of power by switching to a different prand prop.

hi all,

once more id like to know if the 14x4 W APC props are good for the os 91 four stroke???????

I ran a 15x4w APC on my Saito .91.... Really liked it.

RE: u can do 3d
 

15-4W APC or 15-4 Pro-Zinger would be the best choices that I have found on the Saito 91 which is what I have on the 46 size UCD.
