HV MAXX and standard emaxx slipper?
 

hiya,
i just got my hv maxx 4400 today, ran awsome, but then the slipper started slipping alot more then usual, so has it chewed it up already (15 mins), or has it just loosened up? also how long do yous think itll last on a standard slipper?

i ran a 6.5 on the stock slipper for almost a year with no issues, but it had to be tightened down a fair amount...which negates the purpose of a slipper, lol. make sure you have a tough-as-nails drivetrain if going that route. unfortunately, a strobe slipper is kind of out of the question for hv due to the limited mod1 pinion sizes.

IF you do, remember to install slipper pegs into ALL the holes to help with durability.

Ultimately you need to move to one of the following:

1) RRP Dual Disk Slipper
2) Strobe Dual Disk Slipper
3) HSR Motorsports Dual Disk Slipper

#2 & #3 are the best choices. BTW..the new release date for the HSR slippers is end of June.

thanks alot, where and how much could i get one of those aftermarket slipper kits, also im wondering how far out the pegs should stick, should you be able to notice them sticking out by looking at them?

yep - the pegs should stick out a slight amount.

the RR slipper can be purchased at tower - or mike can maybe get a setup for you. the strobe can be purchased here. not sure about the HSR deal - procharged can get you that info.

again for the strobe, though, you're limited to a 51t spur... i don't think there is a pinion low enough to match a ratio that the HV will handle.

Not sure what ratio you need but I expect to have 48T thru 54T mod 1 spurs available. Pinions can be had up to 24T, some custom, some stocked.

oh thats not the sort of gearing im looking for, looking for 72:15 so yeah, i see that the pegs are in every second hole, and i know i cant put any in the hole above because the slipper isnt big enough so would i be able to fit them to all the holes that the slipper covers? or would there be something wrong with that?

Yes, put them in all the holes that the slipper disks cover!

More pegs, more holding power!

thanks alot mate, one more thing, i dont know much about this gearbox, so should i get 2 or do i only need one idler gear to make it harder to break?

it depends if you have a single speed or a 2 speed. If you have the stock 2 speed trans you need 2 idlers if you have a single speed you need one idler.

ok,what if ive locked it into 2nd, do i still need the second one?
also was thinking of this:

is that any good?

i am pretty sure you will only need one with the locked trans but see what the other guys have to say. as far as the slipper i don't see many people using it and it does not appear to have anything wrong looking with it but i did rear a bad review on it here but i don't know if they just had a bad experience.

you only need 1 idler with your tranny locked in 2nd. the extra unused idler is part of the weight savings i had by just taking it out.

i had the RR slipper for a while... it was ok. nothing great. i ended up going back to 12 pegs in the stock setup b/c i somehow bent one of the aluminum discs. no idea how, but it was $35 down the tubes. the stock stuff is cheap to replace.

thanks alot guys, one last question, when its in second gear, is the shifting rod in or out?

all the way in. the 2nd gear is closest to the spur gear (compared to 1st gear).

ah......that would explain the extreme torque and not so 57mph top speed, but should i keep it in 1st? my gearing is very high (66t spur 21t (i think) pinion)

i would go in the opposite direction and lock it in 2nd, but gear down. waaaaaaay down. i found novak's recommendation of 70/12 or 70/13 tops (on 7 cells) to be about perfect at keeping motor, esc and battery temps all within the right range. with your gearing, i'm really surprised it hasn't thermalled yet. :036:

yeah it was a little hot after 15 mins, but probably didnt thermal coz its in first, ill probably be getting a 13t pinion and 70t spur today, so it should go a bit better then, thanks alot

Do you have any pics of your set-up? RTR weight?
My Gmaxx weighs in at 12.5lbs RTR, so I had to lock it into 1st gear and I use 17/66 gearing (about 30:1 overall). Its the price we have to pay for using the HVMaxx system I guess in a heavier than stock truck.

Clodmaxx- how much did your maxx weigh RTR with the 6.5 you were using/gearing?

i only have an exact weight sans batteries - 9lbs 7.5oz. i believe i weighed my 7 cell ni-mh packs at around 1.25lbs, so around 12lbs RTR.

with 70/12 gearing, and about 75 degree ambient temps running in grass and dirt, the motor and esc temps were at ~130 degrees, batts were around 90 degrees.

Wow, that sounds pretty respectable- did you use 2nd gear mainly- aprox speeds? I'm liking the 6.5 motor as a possible replcement for my original 4400 version....

unfortunately i didn't have a chance to get speeds, but due to the low gearing (i have my tranny locked in 2nd) i would guess low to mid 30's. i did clock it one time last fall at just over 38 mph, but that was at 70/15 on 7 cells in 2nd gear...with a lot less aluminum than i have now, lol.

mine technically isn't a 6.5 - i have the 4400 motor with the 6.5 sintered rotor. that new rotor is a pretty noticable improvement - mainly at keeping temps down.
