Speed runs 2200 or 2650?
 

My buddy argued me down that the 2200 is better for speed runs I say 2650 so let me ask some pros that have been doing it longer.Can the 2200 out gear the 2650?

As has been discussed in your other thread, there are a few variables to consider: size of motor, kv, voltage, gearing (also size/weight of vehicle)

The 2200 is a larger motor, so it can put out more power. With the proper voltage and gearing, it should be a better motor for a speed run in an 1/8 scale vehicle. (However, if you were asking about speed runs in a 1/10 scale vehicle, the lower weight of the 2650 might make it the better choice.)

I can help with this. In my mbx5 on road I run the 2200 on 5s and it flies. I have it geared for 50+ or so and it only gets warm. My thoughts were simple...put in a bigger motor in the car than I intend to need especially doing speed runs. I also have a 1520 and I am temped to try it to see just how fast I can go

Just my 2cents

ques.Ok brian015 will the 2200 be faster than the 2650 on 6s which one wil get top speed faster?ques#2.How much more faster is the 2650 than the 2200 on 6s somone give me some facts please greatly appreciated fellows.

edit


Your answer is simple: it depends on how you gear it. If you gear both the 2200 and 2650 the same at 6s theoretically the 2650 would go faster - but you don't need to gear them the same - you could gear the 2200 higher because it is a lower kv and it is a bigger motor.

What will actually work without overheating??? That must be determined by trial and error. You can look at other people's setups and get an idea of what can be achieved.

You gave up offroad already?

Ok sir please fall back from my questions no preshure thankyou

no sir you want to race on road for some c notes premo?

Thanks for your help bud

Well I know that the 2650 on 6s will spin over 50-52K rpm and the 2200 will spin in the 40-44K range so for longevity the 2200 will be your best bet. The 2650 may be faster, however, it won't last as long spinning that fast

Ok now think about this what if I advance the timing to high wont this be techniclly adding kv's to the motor?

yes it will but timing advance wont make up for the difference in kv

here is something else to keep in mind, the 2200 makes more torque, thats going to shorten the life span of the drive train on your car faster than the 2650

as for the 2650 turning at 60k rpm, thats not a big deal, the only part that you need to worrie about is the bearings, if you service them often that 2650 will be happy to run that fast

another thing to keep in mind is the motor will only be revving that high for seconds at a time, if it ever even makes it to max rpm

case in point we have been running a castle 9000kv motor on 3s with no problem for quite some time now and i have a 7700kv motor thats lived threw 2 years of 4s in a mini revo and a touring car.

as long as you service the bearings and watch the temps the motors will be fine


( *FYI this voids your warranty :lol: )

Best info I've gotten mann thanks really informative I made some speed runs
long time ago and as I brought it by the whole car imedietly locked up
And would not roll at all is this bearing failure in my 2650 ?

The 2200kv motor can outgear the 2650, but that doesn't mean it will be faster when the same voltage is being ran on both the 2200 and 2650 motor.

Running 6S:

The 2200 will be able to run a smaller spur and a slightly bigger pinion vs the 2650 motor.
Top speed of the 2200 might be only few MPH more vs the 2650 motor.
In a drag race, the 2200 will be faster if you can control the start up power.
Turning a big pinion with the MMM is iffy vs the smoother Tekin, from a standstill(both sensorless). However, the MMM puts outs more power. So pick your poison.
Stick with 10 degrees of timing. Use timing advance only if you run out of gearing. More timing means more heat in the ESC. Cooler ESC's are more efficient.

From personal experience, I find that Delta wound motors are better in a drag race. Speed runs either Wye or Delta will do.

That's why you're my friend boyyyyyy you shure got this rc stuff sowed up!!!!!!!

It took me a while too figure out what really works and doesn't in my cars. But it was fun doing so.

Spare motors in my tool box. There are another 10 in cars. Kept the best ones and sold the rest. Still not as many motors as some other pimps on this forum. When I get bored running one motor, I just swap a different one in and boredom is gone.

Dude what the fu@# so at last ive found the reason why no companys got motors whats the best one ya got for on raod 1/8 scale?

What are the criteria to the speed run? Drag race? Top speed? Ease of use?

I wanted a simple way to run 100mph, so I bought a hyper 8.5 with a 2650 in it. For normal running I gear for 50mph on 4s. If I want, I can throw on a big pinion and 6s and run 100. I don't need custom spools or crazy gearing setups to run 100mph. Isn't that fast enough?

A 2200 can achieve a higher overall top speed given enough room and wacky gearing, but they are out of sight by that time.

I can't wait to see some triple digit speeds fellas!:yes:

Best one? Dunno, they all have a different feel to them.

Smoothest sensorless is the C50 Hacker w/Tekin
Beastly is the BigMax Pletty
Castle is good for where torque is needed
Favorite Sensored would be the Novak motor and Tekin second.

I haven't used the Hobbywing, Thunderpower, LRP or Orion sensored 4 pole motors. I would only buy a used LRP when they start to pop up. I have no interest in the other ones.

To me:
Speedrun ~300ft
Dragrace ~132ft or whatever distance agreed upon. My son and I do 78ft drag races. Tons of fun with crt.5.
Top speed ~ whatever I'm happy with, which is 70-75mph. I don't have space for anything faster. Don't have time really to got out, just to do some triple digit speeds.

So by me having a limitation of speed and distance, I have to get creative to get more out of my cars. That is why Mike Revo spool will be a nice asset to have. I get to use cheap plastic spurs and save my pinions from getting eaten up so quick. Plus get to us a wider variety of motors and no loud gears to disturb the neighbors at 11pm.

impressive collection...you just may give the pimp a run for his $

All knoledge from the snellemin motor god will be taken seriously all vote say I

Motor god....huh don't think so. I'm just scratching the surface compared to other brainy members on this forum.

now I know how small my rc habbit is

funny you should say that....I was telling my co-worker today that compared to some, my 5 rc's are in small comparison to others collections

Will the 2650 pull this gear guys 42 spur 35 pinnion for a one time 400ft speed pass?In a 1/8 scale 4 wheel dr buggy thanks.
