Octura 642 sharpened and balanced is a good start.

nice looking boat
iam running the ammo 2300 with an etti with x642
let me know what speeds your getting

[MAXAMUS]

not happy with the speeds so far a poor 38.2 mph
thought I'd be hitting the top 40's at least

I wonder how some guys hit 50 mph with ammo!!!
Can you tell me what prop and what batteries?

[MAXAMUS]

Well i could ask the same question to !!

i am running a x642 prop and 2x 2cell lipo's at 6600mah

but i would think to try a x642 with 2x 3cell lipo's at 4000 mah 20c or higher

i also have a x645 prop but as yet no tried it

In my experience the X642 doesn't allow the Ammo to rev. You will need to detongue it. Or get an M642.
An X640 seems to give me slightly more speed & less current drain in a mono. Might do the same in a cat. Not sure on that.
A Grimracer 40 X 52/3 blade is also a good prop on the Ammo. Again that's in a mono, But I did try it on an 8XL in my 32" cat & it was pretty damn fast.
The Ammo needs to rev, it's not a high torque motor.
Don't try the X645 on the Ammo. It will burn.

I am using the ammo 2300 in my Campbell shovel with a Prather 215 and GPS says 43.4 MPH (70 kph). It runs faster but the GPS added 147 grams and it ran a bit wet on the sponsons. A friend of mine has the BJ26 and used a Prather 220 and said it was the best it has ever run but he had a stock setup.

[ozzie-crawl]

pranther 215 is about the same as a x640, he would have got away with a 220 with a stock motor as it is a lower kv and 6 pole, a pranther 220 would kill a ammo

The X645 is a great prop for the stock motor. Keep it for that if you intend to use that motor in another boat.
