Ugh well my temp gun got trashed(spilled epoxy on it..) but the batteries had absolutely NO heat in them, the esc was pretty warm but i could hold i finger on it. the motor was HOT. but that was partially my fault b/c i increased timing on it.
|
Was the motor running cool before you increased the timing?
|
it was hot, but i could hold a finger on it for a few seconds. im gonna fiddle with the esc to find the sweet spot
|
Hmm, do you think maybe the motor is a bit fast?
|
it could be, but mind you this motor has no heatsink, no fan on it, same with the esc (yet) running on 5s. you cant expect it to stay ice cold :D
|
So the zippy packs work good then? I was considering them for some of my RCs (and possibly a big project)...:mdr:
|
definately!! i love mine, that and the imax b5 charger is awesom too
|
Could you measure the distance between the mounting holes on the front? I may have come up with a cunning plan.
|
Right now im at my Nana's house with the raze, ill scan the little spec sheet that came with the motor for you. What might this plan b?
Ive run 2 packs through the raze today, my rear tires are slicks now... but the problem is i keep losing hardware... never to be found again |
Maybe have Mike make you a heatsink to put on the spinning part of the motor, then it would also create a huge fan blowing on all other components which should (hopefully) make them run cooler as well. May totally not work but it was worth throwing it out there. :neutral:
|
I see where your coming from, just hav like angled fins, or just strait fins...i dont have money for that, unless mike is willing to use me as a guinea pig (I HOPE!!)
MIKE U BETTER READ THIS |
Well after two days of running, ive balded 2 sets of rear tires, blown the foam out of 2 tires, all without thermaling the esc.
When i finally actually peaked the pack, the mm's overvoltage thing kicked in, so i had to turn the car on and off a few times... Here is the first look at the Brushless raze! http://i152.photobucket.com/albums/s...0/100_0952.jpg http://i152.photobucket.com/albums/s...0/100_0953.jpg Here is the blown tire from today http://i152.photobucket.com/albums/s...0/100_0955.jpg i lost both of my lower kingpin screws.... then in the process of trying to fix them, stripped the threads in the Hub itself... so new ones will be on the way shortly http://i152.photobucket.com/albums/s...0/100_0951.jpg I have a nice set of road tires now! i think im gonna hit them with some wd40 to soften the rubber for more bite... i havent seen a wheelie yet... http://i152.photobucket.com/albums/s...0/100_0957.jpg |

If you use the "timer" feature of your camera you can hold it more still when you snap the photo, it will net clearer photos ;) When you (I) push the button to snap the photo it's almost impossible to not shake the camera just a touch.
|
P.S. just noticed the boots, you been playing fire fighter?
And nice job on the DD, are you going to go for 4wd? |
1- i know, i need to stay still
2.Those are my sisters boots, she is a firefighter and emt.....(weird yes..) i just used her room cuz its got better light 3. i plan to run 4wd when i ever find a short enuff dogbone and thanks! |
Servo horn's screw is backing out...:mdr:
Nice tires too. Now if you can manage to make it 4wd again, your tire problem will probably ease up, and you'll have monstrous amounts of traction. I like the simplicity of the setup. Have you considered doing direct diff for the front as well? A guy over at RC zone (GordonFreeman username) did a direct to diff setup for both the front and rear of his buggy. The only catch is you need two ESCs and two batteries. |
i actually need to switch that servo.. its acting stupid, think the gears are stripped... it would not hold center
i need one midget of a dogbone to fit in there...i dont know if a dogbone will even work because of the deflection angle. The setup itself is very simple, easy to do. I have seen Gordon, but his car has got to be really heavy with 2 outrunners and escs |
Hmm, I'd move the motor to the rear more, lower it as much as possible, and have Mike make two driveshafts, voila, 4wd! Thanks for this thread, I've got two buggies collecting dust that I now want to convert with an outrunner like you did.
|
i know, this setup was thrown together on friday night so i could wreck my freinds nitro rs4 evo+
..i did... I dont have money for new dogbones! l0ol srry for being so blunt.. not unless anyone would like to help a brother out? lol |
I've got a bunch of e-maxx front cvd's, pin on one end, cvd on the other, 6mm shaft size. They're pretty short, I can't get a measurement till tomorrow, if you can grind the front motor shaft down to 6mm it just might work, can you get a measurement of the length you need?
|
i need like 65-70mm and its 8mm shaft, i would rather not shave down the shaft if i dont have to
|
|
i wanna say that's about their length, but I can't help ya if you're stuck to 8mm, but I understand....
|
can you drill them out?
|
Nice!:yes:
That looks like a really good performer. :yipi: |
FYI.
I did this a few months ago. It was on a hyper 7. Almost the same motor only 550 kv. Emaxx CVD's in the rear drilled out to 8mm, dog bone in the front. Shaved the motor shaft down a little (like and 1/8"). Offset the motor to one side to center the batteries. I the motor would get REALLY hot on 5s works perfect with a 4s. Just as fast as the gas guys. I never thermaled a mamba max on 4s with this setup. The buggy would wheely on pavement. Hope that helps. |
Looks good, I would move the motor back and get two custom made dog bones when you go 4wd. Glad to hear the mm is doing good, are you running 4s or 5s?
Another thing, axi makes a fan thingy (vein shaped fins) that draw air thru the motor. It bolts onto the end of the motor that spins. Sike has had great success with this lowering temps, and I have one for the redcat axi. Something like this, but bigger : http://www3.towerhobbies.com/cgi-bin...?&I=LXPRB0&P=7 Speaking of that, heres a pic of that old thing, I plan to put a mm in it and some bigger tires. 4s would be fine with the taller tires, I was runniing 5s with the shorter ones. http://i206.photobucket.com/albums/b...p/DSCF1687.jpg http://i206.photobucket.com/albums/b...p/DSCF1688.jpg |
Mike makes a 72mm dogbone http://www.rc-monster.com/rcm.php?pg=2
|
Im running 5s, im ordering my parts today or tonite, i think i found a solution... the front center shaft for a warhead is just about the perfect size... :D
I could NOT get this thing to wheely, it would spin the tires at 35 if i gun it.. but the rear end does squat alot.. looks really awesome |
Rcmonkey, would you pay 50 bux for two dogbones?
that price is kinda steep |
Looks good BB! Now all you need is a front dogbone.
|
Im ordering the set for the warhead, according to the b4 dogbone (same length as the warhead's) i dont "need" to move the motor, with the motor up in the front the car handles awesome...the only thing i want is wheelies! that is the compromize...
Im hoping to pickup a new set of stock wheels and tires for like 10 bux. |

|
The warhead ones are pretty strong. I use them.
|
Hey guys just a little update.. With the raze being out of running condition, im taking the time to make a nice motor mount out of reall angle aluminum... the last one was some 1.5in flat stock bent over a jack stand.. :lol: Mind you the sole purpose of the maiden voyage was to wreck my Freind Josh's Nitro Rs4 ev0+.. I did. now to make the arrangements final. :P
I am also installing my spare Hs-311 servo... its a standard plastic geared servo but it works for what i need. I also orded the following this morning during Mech Drawing class :LOL: 1. Raze center shaft set 2. Warhead center shaft set 3. C-hubs 4. Aluminum front knuckles 5. locknuts I finally snapped some good pics too, here you go without further ado http://i152.photobucket.com/albums/s...0/100_0966.jpg http://i152.photobucket.com/albums/s...0/100_0967.jpg http://i152.photobucket.com/albums/s...0/100_0968.jpg http://i152.photobucket.com/albums/s...0/100_0970.jpg |
hey guys, i just got in from the garage, i slid the motor shaft in some more so now i can put a drive cup on either side.. since the rc10 dogbone and the warhead dogbone are basically the same length this should turn out perfect, i the middle of the motor is DEAD centered on the 4 holes for the center diff, that is as far back as the motor can go. and the motor will be as low as possible too
|
The car weights 8lbs 4oz fully loaded with battery, i thought it would weigh more then that personally
|
Sounds like you got a good setup in the works. Not too bad of a weight either. Still wouldn't want to get hit by it at 48mph though....
|
oh i had my moments..... my steering servo decided to go nascar..... TURN LEFT!!!!! almost hit the neighborkids leg...
haha |
