hi,

i have a katanaP, not the OMP one but from someone else which is exactly the same. i need to get an engine for it..... i already have a saito91 and was thinking whether it's a good idea to use that or buy a saito72. there's only a 3oz difference between the 2 engines which is not a lot. so what to do... to spend money and buy the 72 or to use the 91?


thanks

use the 91

Yep, use the .91.....Alot of people are useing .91s in 40 size fun-fly planes

If ya got it, fly it! Go for the 91.

A 91 will be more power than this plane will even need. My ARF is great with the Saito 72, I can't imagine it with a 91.

Check your ground clearance. I run a 14x4, and it sits pretty low. Just a thought...

thanks...i think i'm going to try the saito91. the ground clearance is ok even with the 15x4W.... what prop should i use...15x4W or 14x4?

I liked the 15x5W APC on mine. It snatched the 6 pound Funtana all over the sky.
