I still don't see how the Matrix MVP could run that much cooler. I mean the regular MVP you could have a barbeque with after a run...

So has anyone tried trinity's new "cross-serrated" brush? How does it perform? Also, is trinity's 4503 brush(99 plus) a better stock motor brush than their 4499? They say it has more silver in it.

dont bother trying the cross cut brushes they not as good as the normal 4503's

Putum and reedy 767 are the best brushes

Actually, 4505's do work well in certain situations, & the Monster does seem to like them at times. When I first started running the Monster, I ran it with 767's & tried a few 4499's(but sacrificed torque with those), but then I gave some 4505's a shot, & actually I was impressed. They seemed to let the Monster rev like it should, but didn't sacrifice low-speed torque(what torque they have), so they seemed to equal 767's for power. However, I've also noticed that the Monster seems to change its "mind" about what it wants to run, too. When I first started using 4505's, I did so because for some reason my Monsters were falling off with 767's(still haven't figured out why), so I experimented until I found 4505's, & then I was quite happy for awhile. But after about a month, it happened again, my Monsters were falling off again(as their comm diameters were approaching .270"), so I went back to 767's & they picked back up again. I know this seems pretty off the wall, but all I'm saying is don't expect just ONE brush to be perfect for that motor all the time. The one thing that IS consistently different(that I like) about the crosscuts(4505's) is that they do seem to be easier on the comm than 767's are, every time I've cut the comm on a motor using them I haven't had to remove as much material, & it's been pretty easy to true it up with one light pass(while with other brushes, sometimes I've needed as many as 3 solid passes to get it true, & this is running the motor under the exact same conditions & number of runs but just using the different brush). Oh, & about 4505's vs. 4503's, actually I had very little luck with 4503's, even though they're the same brush compound, I've definitely had better results with 4505's(& I think the crosscut is why they seem to be easier on the comm)....

I've used the 4505 cross cuts on a yokomo based motor and the over all power came up. It did show on the dyno but when I put it in an Oval I could feel the difference.

Guys;

I know some People who Swear that turning your Brushes over after they've been run a few times gives you noticeably more power.
Anyone want to comment?

What do you mean. Flip the brush around?

schumacher

take the brush out, rotate thru 180degs and reinsert.

the trailing edge ona brush usualy gets caked in carbon so doing this should even the wear out i suppose? i don't know i've not tried it.

Thanks Grizzbob, alot of helpfull information there, I appreciate that and understand what you are saying, your car was fast at the Oklahoma Invite race, thanks.

popsracer/schumacher, couldn't you just use a fiberglass comm stick so the brush is still mated with the comm?

popsracer

Yes this is what I feel is correct.

I have however personally seen People turn their Brushes over 180 and get a noticable Power increase, and thus the reason for my question. I should add that this is done by People who are consistantly the fastest racers on the local "Club" level in our area.

Maybe someone can eleborate on the "Science" of this practice.

Thanks,

maybe if the brush isnt worn right in the middle flipping it over means it might have a slight timining advance on it so it gains a little power but yeh dont know cos ive never tried it.

schumacher

hi all,

the monster horsepower has been added to my review collection, it shafted everything else in sight.

Sanj,

Wow! THANKS for the Monster review, quite an eye opener! I was looking for a new motor and had about decided to go with the Core stock, but your test method and the numbers you get from it tell the story.

One question though, I see in the comparison chart at the bottom that you list the "Can Design" of the Monster as Kyosho; is that correct (not Epic)? (as you can guess, I haven't even seen a Monster yet).

Thanks again! -John

schumacher

i had to get that bit from trinity, there is a pcb over where the can marking goes and i couldn't find any other can markings so i assumed it was a kyosho.

hey guys, help me out here...I went to a regional race and we got this "stock" motor. Its gunmetal can, has 4 large rectangular vents on each flat spot on the can, baby blue plastic top with chrome tabs, blue springs, and serrated brushes. They said it was a paradox motor...it said epic on the can, BUT it looked like a chameleon can or something. Any info? What the best way to get the most power out of this particular motor? I went with Red/Green combo and 4505's. any help would be appreciated.
