Outrunner question

[skogsvild]

Im new to brushless so i dont know a **** what i can use so please help me.

This is the spec im going to use:
Mad force axels
jumbo swamp dawgs
e-maxx tranny with 72t spurgear
gi joe 1:6 willys body
custom made tub chassie

Would this motor be any good in a crawler?

I think it going to be heavy and big. Havent start the build yet so i cant tell how much its going to weight. Just collecting parts so i have everything when im start building it.

Please help me what BL motor im going to use

(have done a search but i didnt find what i looking for)

[skogsvild]

Come on!!!

There are lots of people here that run BL so can't you stop and help me out here????

I think that motor would be ok with a gd600 gear reduction and running on 7 or 8 cells it should do anything you want it to.Just watch the temps real close you will have to mess with your gearing to get it perfect.

Check out My new Twin chassis and brushless turbo diesel

A twin with BL, I'm sure Raptorman57 will be able to help.

The setup wouldnt have enough reduction for that smaller diameter motor. You are looking at an $80 + motor to push those tires around at a "normal" reduction and groundspeed. I wouldnt give a $26 motor much of a lifespan or efficiency rating either. As Dez once said to me "No such thing as a free lunch"

OK.

What motor of these 3 you listed should i choose?
2820/08
2820/10
2820/12

Do i need a gd-600 with thoose motors?

[microgoat]

YOu won't need a GD. Outrunners spin plenty slow and have enough torque without the extra reduction.

Depends on the working voltage you want to use. I would get either the 8 turn or the 10 turn.

[skogsvild]

ok thx im going to order the 10turn motor

Thx for all the answer's guy's

I've heard alot of good things on the AXI motors,but never run one. The last brushless motor I ran was an MPJet 28/20-7. I was running a 3.0 GD600,16t pinion and a 53t spur,I believe my final ration was somewhere around 70,75:1. I don't know if I got a bad one or the quality just isn't there. The thing had AWESOME power....until the arm started falling apart and one of the wires broke. Right now I'm back to a gimpy brushed motor but am trying to decide between the Axi motors or these....

HYPERION Z30 Series

[skogsvild]

This one look good.
I belive that the bigger the stator is, the more torque they have or am i wrong?

HP-Z3025-10
Stator Diam. mm 30
Stator Length mm 25
Weight g 186
Outside Diameter mm 37
Length mm 50
Output Shaft Diameter mm 5
Mount Screw Diameter mm 3
Max eff. Current A 27-37
Peak current 46A 60sec
54A 10sec
LiPo cells 2~4
NiMH & NiCd cells 6~12
Winding 10T
Resistance Ohm 0.0250
Io A 2.3
KV rpm/V 815

novak crawler, easiest way for your first brushless system, especially if you dont know anybody firsthand or have a lhs with brushless knowledge

But,if you do a little reseach and learn.....you can get a MUCH better system with ALOT more power for ALOT less money

[Thorsteenster]

yeah but one other thing i figure is that then i can prolong learning how to solder, but in doing some more figuring, its gonna cost me quite a bit not learning to solder!

Yes, the larger the stator diameter and length the greater the torque. I will be carrying various lengths of this motor within the next few weeks. I order the first batch tommorow.

As an added bonus I will offer each motor with a 3.17mm shaft for a $7 upgrade. Otherwise they have 5mm shaft diameters.

Do you have a price on these yet? I am assuming that they should work with a mamba 25 esc?

Thanks

That depends on the model and vehicle. In a tlt just about any will work with a mamba 25. In a super rig the 30-13 and above will want a larger esc like the mamba maxx.

As far as price, it again depends on the motor size. The 30-07 retails around $67. Add in $7 for turning down the shaft and that is your price. Each step up in size is about $5 I think.

I am currently testing the smaller motor sizes to see where they fall and how much punishment they will take. I see no reason why a tlt could not use the 30-07. A super rig shafty would want a 30-19 in the heat of the summer. A Clod would run well on the 30-13's. This is all just a guesstimate from my experience though, until actual testing occurs it is hard to say which is best for each application.

allrighty, im starting a thread for brushless recomendations with specific equipment. id rather see what people are using/recomending and check those out and then choose.
