| New battery and motor?
I have been running my crawler a lot lately and have started to see myself needing more power and longer run times. I currently have a 55 turn motor and a 7 cell saddle pack style battery, that is 8.4v and 1500 mah. I was looking at a 35 turn holmes hobbies hand wound motor, an LD Racing behind the axle steering kit which would get me better approach angles and is set up for a lipo battery that would keep my center of gravity down. This set up will not work with my batteries so I have been looking at a couple 7.4v 1300 mah LiPo batteries. My question is will this set up get more more low end power and will a few batteries have a good run time? Will I be able to run this with my stock ax-10 speed controller?

Bump. I know this isn't 100% axial specific but is anyone running this set up?

| I run a JPH 37T handwound on a 2cell Lipo with my Stock Axial ESC. The 35T will give you more wheel speed, but a little less torque. If your saddle pack is mounted on the the axle, that's pretty low CG.

I might be confused on this, but what does the turn mean on the motor? I don't need a high wheel speed because I do a lot of rock crawling, so I need low end power. Isn't that what a 35 turn motor is for? What is a 55 turn for? The center of gravity on my rig now is ok, but if a lipo can give me more run time I would like to switch from my saddle packs to lipo.

So when using a bigger motor and battery, do I need to be worried about my esc and radio?

I would also watch some vids on you tube and try and figure out what kind of driver you are. Some guys like gobs of torque and run a 55T or higher and like to be very technical, others run a lower turn # and use the increase in wheel speed to get through some areas. Also, if your crawler is a boat anchor, you may have to stay with a higher turn motor.... Just my .05 cents worth. | |

I am leaning towards this 55 turn motor, but will I have to change my ESC or anything if I swap this in? I need torque and power, not a lot of wheel spin, and I think changing the ring and pinion if my motor is too low, because I think the 45 turn will always bee too high. I did get the battery but I have to go to a friends house to extend the wries and solder the connections, so I have not tested it yet. https://www.tcscrawlers.com/Holmes-H...n-p-17869.html Last edited by provin1327; 11-06-2010 at 09:44 PM. |

That motor will drop right in. If you are going to run lipo, you will need to add a lipo alarm to your stock ESC so the voltage dosn't drop below 6 volts or it could damage the battery.

I run the Novak Goat crawler brushless system and i have 2 2000mah maxamps 2s lipo. i get a lot of run time out of them (45min-1 hour usually). i have a parallel connector and if im expecting a long crawl ill connect the 2 for 4000mah.

I have a 35T Holmes Hobbies Handwound and it is about the best motor out there. You can run it on the stock esc, but you will want to get a different esc eventually with a drag brake. The stock esc doesn't have a drag brake. I run mine on a FXR with 3s Hyperion lipo. You metioned that you don't need wheel speed. I beg to driffer. You do need wheel speed in order to do dig manuvers. Yes you do need a lot of torque for crawling, but my 35t HH has more torque than you could imagine. Get the 35t Holmes motor, you won't be sorry. |

X2 on the HH 35t!!!! Also, get yourself a Tekin FXr, so you get all of its silky smoothness, and you can run 3s lipo.

Hmm you do bring up a good point about speed, and I just realized I was looking at a 35 turn motor and I called it a 55 turn doh. I don't run a dig and plan on keeping it a rig with drive shafts and no rear steer, for now that is. I have a 55t motor on there now, but it's not hand wound. I just need more power!!! An esc with a brake would be nice, hmm so many options. Does anyone else make a good ESC other than Tekin? I think I have heard someone talk about a mamba, what is that?

The top esc's out there are the FXR, Mamba Max Pro, and Holmes Hobbies BR-XL. The Mamba Max imo is way over kill. I went with the FXR mostly because of its size. It is about half the size of the others. If you are needing more power that motor is sick! I had the same 50t axial motor you had. The HH 35t hand wound is smaller, stronger, smoother, faster, better. You won't be sorry. |

Castle creations 1/10 sidewinder is a good esc too. Wheel speed is just as important as torque 35t is the way to go. However I would suggest 3s lipo if you change your esc |

Yep thats the ESC. You can find it at CKRC for a little cheaper. | |
