i got a pede xl5, not as fast(top end) as i hoped. the accel is great, even with the 23t pinion. im running 6cell 3300 mah pacs, ill have a 7cell pac soon, and hope that will help. also bought a used team orion 15t(mostly cause iv read the titans dont last long) maybe that motor will do a little better.

if you haven't opened the motor, return it and save up for brushless

nitrosportsandrunner

iv already used the motor, i bought a rolling chassis, then got a package deal off here of a tq2 tx, rx, titan 12t, xl5 all new for $50 shipped. considering that on ebay an xl5 is at least $30 and tx and rx like $25, i basically got the motor free!
i wish i could go brushless right now, but buying all the stuff for this pede costs $110, a long way away from a brushless. plus, brushless isnt any better than xl5 with the same 6cell batts, it needs lipos to go faster. that means more money. yeh, if i had the cash, id do it but i dont.

Gear it down. You should be geared with a 13t pinion and you're 23! Watch your temps.

My Feedback: (1)

I would say for you to send it back and save up for a decent brushless system.

There is nothing wrong with staying brushed in a Pede and a 15t is probably the best turn motor for the Pede. It will give you plenty of enjoyment.

j.m.

Not really, and usually no. MAybe with the vxl system, but that's only 3500kv. Try this:

Performance about like the 15 turn you have, but even longer run times. If you want true speed on a 6 cell pack, try this:

http://www3.towerhobbies.com/cgi-bin...&I=LXNLY4&P=ML

Speeds to be expected around 60mph. it's 10,500kv, so it should hit about 90,000 rpm unloaded.

nitrosportsandrunner - swap out the pinion. 23T is way to high for a 15turn motor. You need to be at 14/15 tooth. Question, Do you hav the XL5 ESC? If it is the XL5 make sure it's not in training mode (half power). I'm not familiar with that orion motor but if you bought it used there's a good chance it needs a rebuild. If you can, take it apart and look at the brushes and comm. That could be the problem or you could have burned it up from the 23T pinion. I too say that brushless is the way to go but I understand that not everyone has the $180 to drop on parts for their hobby. If you find that you motor junk get yourself a speedgems 15T and a 14T pinion.. Las thing to look for. Does everything turn smoothly? If you still have the stock bushing in the hubs they could be seriously worn to the point where the rear stub axels are binding. It happened to me. I was too stubbern to listen.

j.m.

rpm bearing carriers wouldn't be a bad idea either.

brushlessboy16

yes the stock bushings are power sponges....

if you run in sand or dirt get sealed bearings, or run plain bearings with a dry lubricant

j.m.

All bearings are sealed, Unless you run nitro engine bearings in your electric truck, it's just a matter of what they are sealed or shielded with, and what the balls are made out of. Metal shielded bearings are not as smooth as rubber or teflon sealed, and they don't protect against dirt as much. Also, if the balls are plain steel they are okay, but carbide balls are even better.

yeh, im going to buy bearings soon.
last night i ran the pede with a 6cell matched pack and the 23t pinion(this is traxxas high speed pinion that comes with any new xl5 pede) and it killed the motor. traxxas does say to run the 23t pinion with a 7cell pack,(the stock pinion is a 19t by the way, it would be very slow with 13-14t) must be the motor couldnt spool up enough with that gearing and only 7.2v.
oh well, my local hobby shop has a trinity speed gems 15t for $33, i think ill get that. ill put the 19t on to start with.

nitrosportsandrunner

broke down an got a trinity speed gems 15t quad motor today, its deff better than the titan. any one with a stampede, 2.2 rims and tires and a 15t motor what gearing do you use. right now i have the stock 84t spur and the 23t pinion(runs faster than the 19t pinion and doesnt bog)

j.m.

i would suggest the 19 turn pinion or lower with that motor. The lower turn motor you get, the smaller pinion you MUST have. You are going to burn this one up too.

nitrosportsandrunner

but its slow with the 19t, even with the 23t it hits maybe 25mph. i think its becuase the 23t pinion was for high speed with the stock tires. my tires are smaller, so using the 19t or smaller makes the pede top out way to early. maybe i dont know what im talking about, but shouldnt a pede with a modified 15t 540 be able to go 25mph or faster!?

j.m.

it should be more like 35+.

Your motor is probably really worn, or it got screwed up somehow.

nitrosportsandrunner

no, its brand new. i think the problems in the gearing, and i need to get ball bearings.

j.m.

gear down, and charge your battery. (with a descent peak charger)

pede_187

It's probably BECAUSE it's geared tall that the speed is suffering. You are taking away from the torque of the motor and therefor the top end.

nitrosportsandrunner

i cant wrap my head around this, is a low tooth pinion fast(top speed wise) or is a high tooth pinion? if a high tooth pinion is faster, then why are most people saying i should be using a 13-14t pinion on a 15t motor?

scheibler

it works likes this:
smaller pinion- faster acceleration, less top speed, more runtime
larger pinion- slower acceleration, higher top speed, less runtime, and more heat issues

the opposite is for spur gears:
larger spur- faster acceleration, less top speed, more runtime
smaller spur- slower acceleration, higher top speed, less runtime, and more heat issues

I recommend you get a 13t pinion with the stock spur gear.

hands without shadows

You want to be geared at or around 13/87 with 2.2 tires and a 15t motor on 6 cells. Right now your speed is lacking because the motor is geared so high it doesn't have enough torque to push it any faster.

pede_187

^^^^^^ That's exactly what I said.

john01374

nitrosportsandrunner - these last two guys are dead on. You are geared WAY to high for a 15T motor. I personally have a pede with the stock XL5 wheeels and tires. It's running an XL5 ESC and a speedgems 15T double. On a normal 6 cell pack it runs about 30/32 mph. it's geared 14/87. As for Traxxas's recommended gearing. 23T is for speed runs on flat hard surfaces using the titan 550 size motor AND a 7 cell pack. The titan is larger and has more torque than a 540 but at 23/87 it's still over geared. Traxxas is known to over gear their cars and trucks just to brag about higher MPH. If you continue to run with that gearing the motor will only last a few runs before it's junk and you need to start over. Also, you never answered if you are running the XL5 ESC. If so did you check to see if it's in training mode?

j.m.

like i said over a day ago.
