well if it didnt quit

[reod12x2]

xl-5 no lvd -trencher premounts-stock battery pack

well guys the +wire on the titan 12t fell off about a couple of weeks ago and friday i soldered its up btw one of the poopyist solder jobs i have done. and saturday it died on me

so it ran good for almost 3 stock packs and prior to it quiting it didnt want to go into revers but worked fine in forwords for about 2 mins i slowed to a stop to go into revers and nothing then tried forwards and again nothing

so the hitachi 14.4v motor(550 sized) that i have wanted to try
(visual specs)
-same size as the titan 12t give or take 2-3mm on the lenght
-same bolt pattern (direct bolt up)
-the megnetic feild seems to be 2-3 time stronger
-down side is the motor shaft is rilly short there for having to mount the pinion on backwards

hooked it to the speed control by raping the wires around the esc connectors and put on a 19t pinion(19/90). that pinion contacted the spur by less than 1/3. so off i went and at the end of the half run the spur was still going good

first in pression

on a half dead battery pack it would wheelie from a stand still. and seemed to do half of the top speed from when the titan 12t motor was in(16/90). other than that the motor got luke warm. and when i was running it . it sounded like the comunicator gave off a diffrent sound . it might be becuase of no capacitors on the can itself

on a fully charged battery it didnt seem eny diffrent power wise sept i could whellie going at about a couple mph. defenently has about half the speed compaired to what i had on previously . and at the end of the run the motor was a tenny bit hot



so tomorow what im going to do is hook up the motor properly by soldering the motor wires to it. and make a flat spot on the rotter for the pinion. and after that i will try a gearing of 24/90 and see what it does for it

and i know the motor is getting about half the voltage it should be getting

[mark c]

I'm guessing that motor would be awesome in a rock crawler or scaler. As long as you have fun with it till you can get your pede back where you want it

[rag6]

If you want, you could get the 32p gears conversion. This would let you flip that pinion around to get more contact with the short motor shaft.

[reod12x2]

hay guys installed the motor monday in electrical class and it did a smidg better soldered up to the esc preformance wise

i couldent get the 24t pinion to fit with the 90t spur but still i say this motor geared at 19/90 is about half the speed of what i had previously but run time lasted in around 30min with a stock pack that takes a charge of 2654mah but note i was driving it inside so i couldent rilly hammer it 1 becuase of the waxed floors 2 i didnt find a hole lot out side

other than that i would recomend this motor if you have a dead hitachi drill laying around and are a week away from a new motor but on the other side i would recomend this motor to eny crawler that run's 1/10 brushed

[reod12x2]

hey guy tested the speed last week on the hitachi 14.4v motor

with 2.8"trencher tires geared 19/90 i got a top speed of 14.6mph at peak and 13-13.8mph throught out the almost dead nimh pack i have

so far no failures but the motor gets just as hot as the 12t geared 16/90

[Oaks]

Glad to hear it's working out for you. I'm surprised the 24 tooth pinion didn't fit. Maybe you can drill on the gear case to give the motor more swing?

[reod12x2]

or i should just finaly buy more pinions lol

im not certian it was a 24t pinion or not . i got it out of my mustang vxl

other than that its a good motor (but not the best)




thanks

[O.G.]

Maybe you can drill on the gear case to give the motor more swing?

I've done that before, with my dremel and it worked like a charm.

[reod12x2]

yep i was bored yesterday and did the mod on the trans case .had to remove the rear bumper becuase the motor can was touching.other than that it went fine so i was geared 24/90 with 2.8 trenchers and the battery held at 10v with a 2200mah charge (nice for a stock nimh). so first run it still had good torque and a decent speed but at 90+% throttle there was a weired rpm noise from the motor .so at the end of the run the motor didnt seem eny warmer then when it was geared 19/90

but im not going to run this gearing for a while till i get some upgrades and another motor(whats recomended i cant solder)

so i need to decide if i should get upgrades or finish saveing for a merv? (whats your opinion?)
so far by the end of next week i shold have around 85-100 bucks

hey guys is 65 bucks good for a new spc 2s 6000mah lipo?

[Oaks]

Im not one to recommend what someone else should do with money, but depending on your motor and esc plans - I'd say the entry level SPC packs should work well for you. 5000 mah, 25c 2S $30. 5000 mah 25C 3S $41.

[reod12x2]

oh i got the owner of my lhs to just price check the spc 2s 6000mah lipo and a month later he called me saying it was in(self thought of oh no) a couple months ago . any ways its in his shop ready to go for 65 bucks and cells are at c1)3.85 an c2)3.86 as of last week


as far as the pede upgrade or merv. the pede would be the fastest turn around(rpm front bumper ,strc hing pins, spc 2s) compaired to the merv at 310 +tax

the way moneys going for me i would probably get the merv as a christmas present

is there eny other motors that are long lasting and durable that dont need soldering?

thanks guys

[reod12x2]

so guys with my situation /setup could i gear it at 23/86 from 19/90 with a 2c lipo? i dont want to mess eny thing up yet but from what i hear is that a brushed motor in genaral can be geared up higher on lipo than nimh.

so far the battery change would be 1.6v less but 170 amps or so more lol





(side note if this motor lives long enought i will give a try on 3s lipo)

[reod12x2]

hey guys update.
motor still going strong and now its on 2s lipo. what can i say it dosent have the top speed it used to have but it holds voltage under load so well.

so far with the spc 2s 6000mah lipo. all i have done is half runs on the battery it lasts so long
(i usualy get 15-20 min on 2200mah 7-cell nimh)with this motor im probably getting 60-70min run time lol more than i need

and the motor got a little warmer but probably do to the extended rung time


oh and on another note there was a seconed hitachi drill that the teacher gave me at the end of last school year i finaly opened it up and the motor is dead(well i dont know if it is or not but the hole interior was black and there was 2-3 mm left on the brushes)

so the next motor will probably be the cc 3800kv ,titan 12t or another odd motor like the one i have

bye

Glad to hear you success story with lipo and the hitachi. Just having the ability to run for an hour without failure speaks volumes to the durability of that motor. You don't always have to go fast to have fun later

[Redsawacs]

i would say, play with the gearing. If you can get a larger pinion on the shaft, use a smaller spur gear. Your motor has tons of torque. try a twenty something pinion gear and a 70-80 spur....bottom line....want more topend, use larger pinion and smaller spur. want torque, use the smaller pinion and larger spur. if you drastically change the size of one, change the other one the opposite way to fit

[reod12x2]

ya ive put on the 24/90 gearing but that was with the nimh battery i will have to try it with the lipo and see motor temps do

but yes i will have to try and get more pinions and spurs for the motor to fully unlock its potential


well oaks lipo and the hitachi havent been together that long maybe 3 half runs (i just get bored after a half run or more)
but if i could get a 3s lipo i would deffenently want to try it but that will probably be next year


oh yah 775 posts lol(motor size)

[reod12x2]

okay tongiht went out with the pede an finaly ran a full 6000mah pack on... 24/90 gearing

so far only had to take one stop to let it cool off other than that i think it goes faster than it did on nimh for same gearing

part 2 tomorow

[reod12x2]

well i dont remember what i was puting down for part two
but got in the door a couple of hours ago from a dirt mtb park so far only a shell and a motor
motor lol last fuw mins was running fine looked like it jamed once or something and then quit on me a minute latter
so got the motor out and it was in full rotor lock for some reason
so to invesigate and to make money go further i took the sealed hitachi apart and found nothing not even dirt. i put the rotor from my titan 12t motor and made a hitan(hitachi case an the titan 12t rotor ) motor for a couple minutes worked good for just reving.
then thinking lets try the hitachi rotor and worked perfectly(side note i have about 4-5mm of brushes left oh ya its here to stay)
so what could have cuased this to happen on a sealed end bell motor?

and lipo with this motor is awsome on 24/90 gearing just have to take a break half way throught the pack 6000mah 2s lipo

[reod12x2]

well guys i think i almost fried the motor. just after open rotor surgery

well out for bashing gear the 24/90 on trechers after half the pack i put my finger up to the motor and lets say i felt the heat before i touched the motor

so got some water and cooled it off didnt steam but you could defenently here it (like the sound when you pore water on a hot frying pan)
going out in a couple minutes and see how much torque i lost

still a good motor

That gearing is probably way too high for a brushed motor. I'm thinking 16 or 18/83 would be about right.

[rag6]

Start with 90/16 with the trenchers

[reod12x2]

well ....
i ran the 24/90 gearing with the stock shell on street but what made this special is i had put on a plastic injection mold shell on(alot hevyer than lexan) and went thought a feild this time.

normally its on street with a lighter shell



so far the motor now heats up on 19/90 and hopefully this x mas it will be replaced with the cc mmp sct race pro

Can you have Christmas in September?? I couldn't wait that long.

no i need hing pins,shell ,chassis and another 70 for transmitter an 2 rx's(in for warrenty)
plus other parts to modle the three chassis's for the rustler

rrrrrr wallet malnutrition

[reod12x2]

om... guys umm i acutally thought i was running 24/90 with the hitachi 14.4v on trenchers since day one of installing the pinion but it was acutally 28/90 no wounder the trans neede to be cut a little

holy stress. but even at that it needed a little break(10mins) after every 3000mah's on the lipo so its defenently a good motor sides for the suden overheat that i put on it with a heavyer shell

so umm ya umm it can do 28/90 quight well lol
