motor upgrade.

[avengersteve]

hey i was looking into the fiego motors and being new to electrics, which motor would be best for the most speed with a lot of "jump out of the water" torque? and are they more powerfull than stock sv bl? ill most likely het the barracuda esc depinding on the motor selection.
thanks

The 9XL or the Ammo motor should push it pretty well.

There is also a 2600KV version of the stock motor listed with Great Planes...

I think the SV27 motor "Stock Number" is GPMG5315, which is 1800KV, and the other is GPMG5320, which is 2600KV... That would pump the RPMs up to around 31,000 or so... and would bolt right in place... Specs show max surge current at 55Amps, so the ESC "MAY" hold up to it as well...

thanks for the info darin... i just looked over at rrr and found a post by grim... apparently this is the motor in question...

i wonder if the ESC would handle it ?? since i m a total newby i ll leave it to you blokes who know what you re talking about to figure this one out :)

[NorthernBoater]

As long as you don't use to large of a prop.

[NorthernBoater]

If you would want to stick with the same speed control the Ammo motor would be the better choice. If you went with the 9XL you most likely need to get a different ESC.

what size do ya reckon ?? would the x440 be too large ??

i m guessing the cf48 would spell the death of the esc :)

i have that motor,the ammo one,and it holds up fine with stock sv esc..x440/3,x642/2,hell even a x447/3 will really get the boat pumpin just watch out on batts though.heats them suckas right up.

i m guessing the cf48 would spell the death of the esc :) a 440 would probably be ok, but I would start with a x435, then work your way up. this stuff is to expensive to burn up on the first run!

[part time]

mega 22/35/1e 2500kv or mega 22/45/1 2550kv both are 6 pole so stock esc will work the 22/45 will have more torque due to its 45mm long rotor.

I went with the Ammo (http://www.offshoreelectrics.com/proddetail.php?prod=dh-gpmg5290) for two reasons.
1 grimracer recommended it.
2 dirtysouty31, who runs boats with me, uses it.

Nothing I did to mine was able to keep up with his. Now he put that thing in his Vegas, & I put the stock SV motor in my Bud. He's still about 10mph faster on a heavier boat. I got the Ammo yesterday, thatnks Steven. We'll see :D

[avengersteve]

with the kv ratings, does a higher number mean more power?

[Diegoboy]

Higher number means more RPM

[avengersteve]

thanks, still new to the electric scene,. so much nicer than nitro

[saleens7]

KV is rpm per volt...i.e. 2084 x 14.4v = 30009.6rpm

Hi all, im new to this forum so any advice is welcome;

Having had my SV27 for a few months now I feel the speed is tailing off so I was considering an upgrade to either 7 cells or the ammo motor.

I think I am sold on the ammo 2300.

I am running 6cell IB4200 packs use either v440/3 and x642 props,

Steven has said, make sure to get the ose metal jacket, the stock jacket just doesn't do the trick and to make sure to go to a bit smaller prop.

Having read through this thread, it seams ok to use this motor (any other advice on this is welcome) but can anyone suggest a prop to use?

Sorry if this has been covered, I just want to double check and give myself piece of mind.

Cheers
Allen

x642 on the ammo is my recommendation. :thumbup:

I know Im still a rookie but I like this 8xl cc80 cf45 prop combo. plenty of power and top end and great run times. I removed my cf turn fin and it really unleashed the top speed. handling is a little harder to manage but top speeds are insane. that setup with 2 2 cell lipos mounted as far possible forward
