Will the Castle 2200 be enough motor for a muggy?
 

Just found a great deal on a MMM combo and was wondering if you guys think it will be enough motor for a muggy? I plan to run 4 or 5s with the 2200 motor and gear for around 40mph. The muggy will have either 40 series bowties or a set of badlands, so no huge tires. Trying to keep my battery weight down a bit, most of my 6s packs are quite hefty. And I just got some nice enerland hardcase packs!

Should be powerful enough.

I would go with 5s, I think if you are gearing for 40 it would be fne

Ok, 5s may be a bit too much... I would need to go to an 11t pinion, and I do not think it will fit.. Or go up on the spur size, but that may cause fit issues as well.

Differential Ratio: 4.090909090909091
Transmission Ratio: 1
Other Ratio: 1
Spur Tooth Count: 46
Pinion Tooth Count: 11

4s with a 14t pinion looks just right to me:

Differential Ratio: 4.090909090909091

Or maybe I should scrap the 2200 motor idea and just stick with my c50 10xl... That motor is 1624 kv, so on 6s with a 12t pinion (that should fit...):

Differential Ratio: 4.090909090909091

Ideas?

Try both and let us know...

you could try 5s with the 10xl motor

I'd wait for the 1800 motor - too bad we don't know when beta testing will be over. It will be longer for more torque/cooling and be a better match kv-wise for 5s with room to go to 6s for speed runs.

Kinda what I am thinking... Seems like a bad thing to pass up on a mmm combo for 240 shipped though...

And I do have a plett maxx for 4s usage, mainly why I bought the enerlad 2s hardcase lipos after I sold all of the trakpower packs I had. And I do need another MMM... Maybe I should buy the combo and sell the motor on ebay, would be a cheap MMM that way...

I am thinking about this, although I do not really have a big enough 5s pack. All I have in 5s is a polyrc 3700 25c pack, so good for around 92amps cont. That is fine for the slayer with the c50 15l, but not enough for something with big tires like the muggy...

Ok Chris, can you send me a 2200 castle motor to test....

How long do you need it for? I have a CC Neu Hpi 2200 not installed... Or would sell it...

Any chance of downloading and attaching this pic - I can't get photobucket at the office.

Nice axles!

Looks like Sean beat me to the attachment... Does that work for you or do you want me to put it on photobucket?

As for the hpi motor... Pm me what you want for it... Or if you like I can test it in something.

I am using the CC MMM combo (2200kv) in my muggy, the muggy weighs in at 7.8 lbs with everything except lipos and wheels. My aluminum gmaxx weighs 7.8 with no wheels or lipos too and runs a MMM/2d. Keep the wheels and lipos as light as possible and it works great. Throw on 800g wheels and tires id up it to a bigger motor.

2200 should have no problem pushing a muggy :) now is it of the 6 wheeled variety?

I decided that the money could be spent on a MMM esc and a servo, insted of the 2200 motor. I will just run the 10xl c50 on 6s in the muggy. But thanks for the info...

Nah, the 6x6 lst will have a hacker c50 11xl and a MMM and run 6s lipo. Basically the setup out of my regular lst, geared a bit lower to take some strain off the motor. Thinking 35mph will be plenty for that truck. i will wait for the 1800 or 1500kv cc motors... 2200 on 6s lipo is just too much for my gearing requirements.

I use a 1515 2.5D on 6s in my Muggy, the 1515 seems to power it fine doing 40 - 45 mph. I would snatch it up if it is a good deal. I wouldn't mind a bigger motor for speed runs, of course then battery size may need to be bigger.

Hmm, just scored up a 1515 2d (1900kv) and a neu energy 5000 235c 5s lipo. Methinks that will be the power system for the muggy...

EDIT: Didn't see other post.

I'm impressed! 5Ah @ 235C would be 1175A continuous! I bet the voltage wouldn't drop at all at a mere 200A current draw. Of course, if you ran them that high, runtime would be a little over 15 seconds. :wink: :lol:

Where do you find all these deals....???

Flydma - i was all over that too but didn't realize you can remove the gearbox...

There is still the 1506 if anyone has a crt.5 :)

Yeah I did the math and figured the c rating was a bit high, but it is always nice to have some headroom... Plus you can charge them at 50c, so I need to make a deans to 220v ac adpater and just plug in the wall.

As Arct1k said below... Stuff went quickly last night!!!

Yes you suck - Go play with your trannys ;)

PS can you find be some berg axles...

I can try, let me make some calls on those axles...

Can't play with trannys, Shaun has not called me back yet!
