What's a long lasting P-94 style brush for play?

[tamiya4x4dryver]

I'm going to pick up a 19 turn P-94 type Trinity motor for bashing around. Unless I end up finding someone around here with a comm lathe, I'll likely maintain it with my trusty old comm stick and pen. I've had pretty good luck doing this over the years as long as the motor was a mild modified and I picked my brushes carefully. So.... what P-94 style brush would be best for being easy on the comm and long lasting? I'm not worried that much about the power since it's just for play..... Any help would be greatly appreciated.

i'm using the XXX lemans trinity brushes in my 10 turn cobalt with great success! they last forever,and are super easy on the comm. plus they give great power. i can only think that in a 19 turn they will last even longer and still perform great! they will work in any motor that uses p-94 style brushes. they also make that brush compound into other brush sizes so that they can be used in stock motors,or mods that use stand-up brushes. i am very happy with them if you can't tell! lol
if you have a hobby shop nearby,ask them about getting your comm cut. they will either be able to do it for you,or direct you to someone who can. if you lived near me,i'd cut it for free. most people will.

Thanks for the info! I had asked at the hobby shop before, but for what they charge it wouldn't be cost effective for me.

There are several things that causes brush and comm wear regardless of what dimensions or compound the brush is made of, gearing and improper spring tension are the two major causes number of cells used (voltage) can play a small part. Generally I get less wear on motors used in 4cell racing, than those used in 6cell.

You won't notice much difference in motor speed with one using a standard size standup brush vs one using the P94 style brush. If you are interested in good speed with less wear go with the standard spec 19turn machine wound motor with a low silver brush (Reedy 760) and Red Trinity springs. Using the adjustable endbell 19turn which is what I think you're referring generate more wear since most may be set at 36degrees, some are 24degrees. Another reason you may be mislead to this motor is several reasons, the 4 magnet Epics with P94 style brushes are not legal for most race organizations so in effect you may see claims of being better at a low price. For bashing the Trinity or Kyosho Stock Japan Brush if available is a good brush for bashing and cheap about 1.95 vs 2-4 you pay for others.

If you lived near me I would give you a couple of Spec 19turn motors, since I only use the 19turn Mod style for racing. They consist of Stock Chameleon 1 &2, some Fanton LTE C2 and some Reedy 19t Specs in the Rage style can.

Thanks Highroller. Not 100% sure which motor I'm gonna get. Looking for:

1. 19 turns or higher (my speedo limit)
2. bearings
3. adj. timing
4. Yokomo or Epic based
5. rebuildable
6. machine wound
7. has to be available at Tower Hobbies
8. No fruity chinese motors like a rush, jaguar, havok, or piece of crap venom fireball.... looking for something of decent quality
9. Just playing, not racing.... running a buggy on pavement


any suggestions??

By the way.... those xxx brushes someone listed above are like $13.... holy crap.... I'd rather buy armatures, lol

This is the only motor I see at Tower that meets all my requirements and it takes the P-94 brushes. I'm open to any suggestions... do you see anything else at Tower that meets all my requirements?

19turn mod (hand wound armatures) is big in oval racing. Most of these motors are made by aftermaket motor tuners using OEM motor cans from Epic (Trinity d5/d4endbells), Yokomo (Reedy Ti can/endbell) and TOP (Orion/Peak). Because of the popularity Trinity began making their own 19turn mod motor the first was deemed illegal Epic 19 turn quad (4magnets and P94 brushes were ruled out) now Trinity makes the 19 Teen based on the Cobalt can using standup brushes, handwound armature and adjustable timing see prices of 45-65 dollars (Tower $49.99 #LXKB4), Ultra Bird (uses machine wound epoxy balanced armature (Tower $49.99 for the standard and Pro #LXGVU4, Pro #LXJKA8) there are two styles of Arconite 19turn one uses D4 endbell (standup brush) machine wound armature (Tower $39.99 #LXEXG0) and the Arconite with P94 style brushes (Tower $29.99 #LXDVC5) under the Epic list there's the
Epic Binary2 (split magnet P94 style brush) not legal under ROAR and ACOR (organizations that govern oval, rc racing),(tower 37.99 #LXEXL1 standard, Pro $49.99 #LXEXL2) new version D6can/standup brush F19 (Tower $53.00 #LXKHX3). Most come set with 24 degrees of timing while the Cobalt and Ultra Bird have 36 degrees while this is fine for racing it's a tad much, plus most racers install different springs either two reds, purple/red or two purples in combination with a brush that makes the most power. I've tried the Ultra Bird (machine would armatures leaves something to be desired) the Cobalt is much better but I tired a Cobalt based motor from an aftemarket builder ($45.95 Kisbey Motors) and that was even better but still on a par with the TI and D5 cans equipped motors. Since you ESC may not hold up under the amps these motors draw standard Spec 19turns may be better suited for you right now. In a race setup motors generally pull 12-15amps continuouslywith surges of 50-95 on hard acceleration. If esc is only rated for 80amp then you may exceed that on one occassion causing the esc to be damaged.

Thanks for the info highroller, most appreciated!
