| assembling a motor
Hey John, I got the armature yesterday. Thanks, that was quick! I've got a question about motor assembly though. It's a speed gems can, and I'm assuming that I can use the timing hash mark stickers that are on the can. This wouldn't change from arm to arm, right? If it does change, how do I figure out what is 0 degrees, and what advance timing (if any) should I run it at? Also, this is a noob question, but the timing hash marks have a central 0, with marks up to 40 to the left and right. I assume that turning the endbell counter-clockwise (to the hash marks to the right of 0) advances the timing, correct? Also, how much slop should the arm have up and down? With one washer on the bottom, and one washer plus the insulating washer on the top (endbell end), it has a little slop. If I add one more washer to the bottom it's snug, no slop at all. zero movement. It doesn't bind, but there's no up and down movement of the arm in the can at all.

I would use a 1300 35c pack in 3s since it fits right in the battery slot. I am presently using a 1300 3s. I was wondering how small I can get away with when I switch battery to front axle for 1 5-6 minute course. I have 2 XR10s, 1 3S for practice & fun, and 1 Carbon Fiber 2S, twin front axles, very light. I will keep 3S 1300 in reg rig. Was inquiring for the 2S CF rig. Thankyou for your time pinckbrown |

For shimming, I generally leave just a touch of up and down play. Just be sure the commutator connecting tabs can't crash into the brush hoods. I have come across way too many motors that were shimmed too tight, so be sure that there really is no binding when you add that last washer that give it no play. Quote:
I haven't tried them with the 454 motors. Maybe ask what people have gotten away with running in the electronics forum. | |||

What would you rate the 454's as amp wise? Would they be around a 25-30 amp motor? From what I can gather the micro sidewinder is 25, b1r is 30 and the mamba micro is 35. Thanks Kieren |

John, I just installed 2 new team motors, and 2 new br-xl's into berg axles. I have 12r/13f pinions. I calibrated the esc's separate before I connected their power together. I am not running a bec and have all wires plugged into the rx. You timed the motors and marked them for front/rear. My problem is that my rear motor turns faster than the front, even with the smaller pinion. Any suggestions? Should I just swap the motors and wire them backwards, or will that effect timing?

| TorqueMaster Pro Handwound 540 35t with 1400mAh 9.6v NiMh
Will the TorqueMaster Pro Handwound 540's 35t coupled with the HH BRXL ESC be ok to run using a 1400mAH 9.6v NiMh battery pack and/or a 1200mAh 8.4v NiMh battery pack in a Axial SCX10 RTR? I ordered a 4500mAh 7.2v NiMh to put in it but I want to put my airsoft batteries to use as well, so I dont have to dump more money on batteries right now, and still have plenty of juice. Im new to the R/C thing so I dont know if it is ok to use high power batteries (in Airsoft its a big no no without doing internal upgrades to the gearbox) would the stock SCX10 transmission be able to handle the extra power? Thanks Matt |

I have a TorqueMaster Handwound 540 35t that has about a dozen runs in my berg and today it died. Only way I can get it run is to turn the pinon about 1/3 of rotation. Then the motor takes off and runs, but if you stop the motor I have to "jump start" it again. I even tried a different speed controler and still have the same results. Any help would be appreciated. Thanks

Hello John, For my XR10 I have 1 TorqueMaster BR-XL, a PunkDig, 2 x 55 T and a Hitec 7980. The 7980 is running on 6V for now. Is the BEC from the TorqueMaster BR-XL enough or do I need a CCBEC? Thanks, Steven |

John... Was wondering if you were ever going to get your Outrunner Brushless 1000KV motors back in? Really would like to have 2 of them for a crazy build. If not what motor's would you recommend for a 30LB 1/4 Crawler. Super Bully Axles, so I am running 2 motor's...

The torquemaster comes set up for crawling. You won't have to do anything except set up the radio endpoints. If you want further adjustment you can get a Castle Link. Your radio shouldn't need anything special to work. | |||||

Sounds like you got a tekin controller. 1 is weakest, 9 is strongest. Play around with it to find the strength you like.

I'm not sure. I may have to switch factories, in which case it would be about two months. If this is the case I will be upgrading the construction for the machine wound.

Hey John, I just sent you an email then realized you were on here. I had ordered a waterproof SC from you that wont ship till the 14th. I was told you could ship a standard (non waterproof) version on tuesday. I don't really run in wet conditions, just ordered it for "insurance". Is it true the warranty is shorter with the waterproof? Would you recommend the waterproof version if I don't "need" it. Thanks, Ron |

Yes, the warranty is shorter as stated on the product page. If you really don't need it, don't sweat it. The controllers are conformal coated so you still get some protection. We can forgo the treatment and ship it tomorrow for you.
