can i run my hpi e10?

[imperium]

ah lol i thought it mighta been something like that i was wiping some off my car and licked my finger and noticed it tasted sweet

i think it also gives the track a cool look like its been driven that way for ages and rubber has built up there

that is our grip. depending on your set up if your dogbones are to loose they will fall outwhen turning or bumping into a wall

yeah i think it happend when i hit a wall, ill have to take a look at it and see if theres anything i can do to prevent it
maybe ill buy proper swing shafts

that's easy Don't hit the wall

[jarrodH]

then why do you??

i meant prevent the dogbone falling out

i got new pinions, now running a 27 (previously 22)

also got a 35 in case there's of a course with a massive straight

ill grab some tires tomorrow from shaver and i should be out at the practice

Be very careful as you have made a big jump in your gearing. Drive the car for about 3mins then check to see how hot your motor is.
We all have burnt up motors from putting to large of a pinon gear on.

Also a note from the Hpi web site about their pinons

HPI Racing is proud to introduce a selection of Pinion Gears ranging from 20T to 35T for the E10 touring car.
These 0.6M pinion gears are a perfect fit on the E10, making gear ratio adjustments quick and easy.
Each pinion is precision machined to the exact factory tolerances for a smooth gear mesh.
A wide range of gears is needed for the various stock and modified motor racing classes,
so most racers will carry several different pinion sizes in their pit boxes.
Each gear is stamped with the number of teeth for easy identification.

Note: These 0.6M pinion gears are not compatible with 48 pitch and 64 pitch spur gears.

wellll crap, jeff paired up the pinion with a spur gear from the car and he said yup 48 pitch

what kinda damage do you think i could do, just wear out my spur? or something serious
side by side i couldnt see a visible difference in the teeth of the 48 and the ".6m"

is it possible hpi just wants people to by into their own parts

on another note i ran the car with the 35t for 3 or 4 minutes up and down the street
it got warm but not hot

plus if i burn out my motor then i have more of an excuse to get a new one

Running two gears of slightly different pitch can end up working alright, even though efficiency suffers a little bit.  That's how the X-ray (or Serpent -- they're both close enough to the same) nitro cars work.  However, if you don't get full engagement, expect a lot of noise and short life.

You may have ended up getting gears the same pitch anyway.  If they look like they engage all the way, then there's no real issue.

Driving the car for 3 or 4 minutes up and down the street is nothing like running a 6 minute race.  What really matters is roll-out -- that's the measure of how far the car travels for each revolution of the motor.  For this, you need the diameter of the wheels (the same for all touring cars), your final drive ratio (the gear reduction of your drivetrain -- similar to the final drive ratio of a pickup truck's axle), and your primary gear ratio (what you're playing with, which is kind of like what gear you're in when you're driving your pickup truck).

Your motor will get much hotter in a race than just playing on the street, especially if you have proper race tires.

As an exercise, see if you can figure out how many millimetres your car travels with each revolution of your motor.  You can double check to see if your answer is approximately correct by eyeballing it with your car on the table.

Checked out HPI's site, and did alittle math for the E10.


Tranny ratio is 2.53
Spur is 65T,
Pinion is 22T
and the FDR is 7.48.


So by changing the FDR (depends on the motor that you have), you would NOT want to higher then a 24T pinion (maybe a 25T on a big track).  Anymore then that and the internal smoke will be released.

well i got myself some new motors and some slicks
i had planned to go to practice today but ended up getting those parts
but i should be at practice next tuesday
