Default 2 pole vs 4 pole question

Sorry if you guys are getting tired of all of my questions, but the answers have been greatly beneficial.

So far I bought the SCTE Ten, Changed the diff fluids, RPM arms and bumpers, Hitech 7954 servo (already had it) Tekin RX8 (had it too) and I ordered the TLR kit that should be here with in a few days.

There are no electronics in the truck at this time.

Run time is important to me, as this truck is just for fun. My son gets 25 min playing around in his stock slash 4x4 and I would get the same in my recently sold 8T 1550 combo.

I want the same with this truck.

I have been reading the 4 pole is a battery killer, 10 min runs? I was, on the track, getting 25 min runs in 1/8 with dual 6200 mah packs.

Should I stick to a 2 pole set up, like a traxxas brushless system, or should I just install the new pro 4 that I have sitting right next to me.

I know the pro 4 4000 is a great motor, but before I solder it up and loose the return ability of it, I want to make sure its not a "gas guzzler" (example)

Thanks

i am running that servo in my 8ight e - works great. ps - i thought it was overkill for an 1/8 ebug.

Doesn't matter what system you put in the truck if you are getting the same output (mph) in the same basic environment it's going to cost you the same mAH at a given voltage. Dial down the 4-pole power and you will get longer uptime.

If you don't plan on racing; Consider a 3s lipo and lower kv motor such as 3400, this will yeild better results and longer run times with out having to give up that extra speed/power.

If you make it to the track; for race days, stick w/ 2s 6000mah to 6800mah packs and def go w the 4pole motor.

Bashing days when you just want run times, run those dual 6200's in parallel and get that same amount of uptime as you do w/ the ebuggy. Though heavier weight = more chance of breakage. Keep in mind a 1/8 ebuggy isn't that much heavier than these scte's and we are running smaller power plants and lower voltage. This is the price we pay to stay in Roar (and most tracks) regs Always a trade off.

One last question before I beat this dead horse any longer.

Seeing that these are similar to 1/8th buggies, would a 1900kv buggy motor be a better option, and or is it even possible to run that combo with 2 cell? (Apples and Oranges but trying to weigh my options and make the best choice.)

Side by side the 1900kv is huge vs the pro 4, Im just new to the 4 pole motors and dont know that much about them vs the 1/8th gear.

i dont think a 1900 will work with a 2s battey, you may need to do some dremmeling to get it to fit not sure tho. 3s is ok but 3s is not allowed in the class at my track and the others that I go to...

its really hard to get high runtimes with these setups. 550 2pole motors fair a bit better from what i have seen. just as much power in my reedy 4.5 and a little smoother

Gonna replace all the bearings in my truck with an avid kit. Do the ceramic bearings really make a diffrence? Regular bearing kit costs $22 while if i switch the diff bearings to ceramic the cost jumps to $46. Is it really worth the extra cost?

I'm going to take the grease out of my diffs and replace it with fluid. I'm going to try 5-5-3 for the indoor clay track I race on. What is the best, fastest, easiest way to remove the grease?

Brake cleaner works good.

The 1900 is a 1512 class motor, it is also 4pole just much bigger. That motor would work on a 3s config just fine, but is really best on 4s lipo. I have seen a few people run the 2600kv castle 1512's on 2s and had pretty good success, that's about the lowest usable config though and takes a pretty good size pinion.

The motor size isn't the problem; in order to get more run time you just need more mAH with the current kv motor or more voltage with lower kv motor. You have a very usable motor, I guess the only thing that could be said is a sensorless motor like the stock RTR losi motor or a castle 2400kv 550 4pole would be a touch more effecient.

hobbyking has a pretty big 2s pack if I recall for traxxas vehicles that would work well in your situation. This would get you close to the run time you are looking for with the equipment you have. Maybe worth looking at.

Noooooooo! Brake cleaner degrades ann ruins some plastics and silicon pieces. Always use motor spray specifically designed for rc's. The fumes from brake cleaner are enough reason to not use it. I use duratrax powershot. No fumes and cleans well.

I use mineral spirits for the grease.

WD 40, is a solvent with lubricating properties. Read the can or the web site. It will get the grease out, and will not tear up your bearings, eat at the plastics, or mess with the o rings.
