Speed Passion LPF speedo - OK for 4wd?
 

I'll need to get an additional speedo when I get my new 4wd and due to budget contraints(!) I'm looking at the Speed Passion LPF range.

Does anyone currently run this in their 4wd and what do I need to be aware of? According to the SP website, there is a 6.5R limit when using Lipo, which should be fine. :D

My other option is to put the LRP Sphere Comp that I have in my B4 into the 4wd and put the SP into the B4...:confused:

Do I need to run the cooling fans on either of these in a 4wd?

Thanks :thumbsup:

What motor are you planning on using?

as it stands, I have a SP 7.5 but might consider using a 6.5 if that doesn't seem quick enough.

Have you raced before etc?

i think there are a few people using the LPF in a 4WD with no probs with a 6.5. Have a search and you should find them

I run a SP 7.5 in my B44, without problems (indoors), but if i was thinking of running the 6.5R (which I would be at least outdoors), then I would plump for the higher spec Pro version, just to be on the safe side.

HTH a bit

I have an LPF on order for my Cougar SV with a 7.5 and I'm using a 7.5 with the GT Pro in my Cat SX. Both the 7.5 and GT are cool to touch.

just started back up after a decade off - hence the lack of kit!

The other option could be the Castle Mamba Max as this is similar price but not sure if the speedo is any good, particularly in terms of feel etc - I don't want a light switch!

I've been really impressed with my SP 7.5 motor, hence looking at the SP speedo...

thanks for your input so far.

7.5 in 2wd outside is a smooth motor :D Hope you enjoy it! They also run cooler outside than indoors due to less stop and start I guess, but my 7.5 in the B44 is geared down quite a bit, because of the lack of straights where I race (indoor sports hall)

6.5 is a nice motor in 4wd for outdoor use..easily fast enough to drive consistently over 5 mins. I tried a 5.5 and it was too fast for me, I was actually slower with it, as it was harder to drive smoothly. The top f1 guys use a 5.5, but they have the skill to go with it! :thumbsup:

I highly rate the SP gear and also rate the Tekin RS / RS Pro ESCs, but they do get warm.

SP LPF is rated to 5.5 not 6.5

I've run mine with a 5.5 in for months without a problem

straight from LPF section of the user manual at speedpassion.net:

Sensorless or sensored brushless motor /
Supports up to 5.5T brushless motor on 6 cell 7.2V
battery, 5 cell with 4.0T and 4 cell with 3.5T, 3 cell Li-Po
battery 9.5T above
2 cell Li-Po battery 6.5T above
3 cell Li-Po battery 13.5T above

I can't speak for the SP equipment as I've not used it but I've been using the Castle Mamba Max Pro (I'm guessing you mean the Pro version and not the Mamba Max) for about four or five months in a variety of applications and couldn't recommend it highly enough.
The throttle feel is superb and is much much smoother than other ESCs that I have used - but like I said at the start, I can't comment on the SP equipment.

Certainly no light switch but it is mega adjustable and is certainly powerful enough for any motor that you're ever likely to run!

If you run the lpf speedo hard in a 4wd it may go pop... my mates did.. running 4 lpf's in 2wd down to 7.5 motors.. i think thats within the safe zone for the lpf...excellent speedo.. none have ever missed a beat!
Also.. using the pro in an x6... very punchy and feels much better.. in comparison the lpf feels a tad flat! Value for money and reliability i think the speed passion speedos and motors are hard to beat imo.
hope that helps:thumbsup:

Schumacher's website says 5.5 with lipo... :S

if you worried use the pro version 120 amp but tbh lpf should be fine providing you dont overgear it by a mile
