Can't wait for the 1/8 motors! ;) Brian |

As a point of reference for those with Copperhead who experience this. If your vehicle shuts off and still has steering one of 2 things has happen.
1) you hit a thermal cutoff. Something registered a temperature high enough to shut the system off. This can come from running to long, being over geared or even a jolt that causes an arc between the bullet connectors on the motor/esc connection. 2) you hit low voltage cut off. This occurs when the motor's amp draw spikes very high and lowers the batteries voltage. Some batteries are able to handle this spike. Others can drop really quickly below LVC which causes a cut off. Can this happen on new batteries- yes, it depends on the quality (not price) of the cells in question. These spikes can occur from pulling throttle very fast, landing a jump, a crash when on throttle. Can this happen every run? Yes, if the same factors are in place it can happen over and over. So if it ever does happen. Check your settings. Lower Punch, Start Power and Forward power can lessen that voltage spike. Try a different battery. Check your bullet connectors (tight and no black marks - from the arc). These questions seem to come up from time to time so I figured I would post some info we see. |

Sorry Jamie James, I'm not familiar at all with the Copperheads.
Folks, I run on a pretty tight outdoor track where pop between the hairpins is a priority. The blue groove is starting to build and I'd like to get a bit more stump pulling power out of the 8.5 turn VTX10 in my SC10. Currently I'm at the stock motor timing and I'm running no boost. Any suggestions on how to start moving in the right direction? Drop the timing a bit and dial up some boost? How much and what settings? |
bds - lower motor timing some will give it little extra bottom end. Also lowering Throttle PWM slightly. 1 or 2 teeth lower in gear will help as well. Believe it or not, you can also try some different chassis settings to help get more forward traction, as this will help put the power to the ground.
Jamie - yes the ProGauge (and EZ Link) will work with all current Viper speed controls. On the Caster forum PM "bring it on" (Rick Jenkins) he developed the Caster 4wd SC using Viper electronics. Sure he would be able to make lots of suggestions!!! xxxn- yes, bec is at times an item that fails, but generally not causing the unit to go into the "reset" that some encounter. |
[QUOTE=nikos2002;12376373]ridgerunner - looked at your motor today - you spun the rotor, it was fighting though, didn't want to let go. It will probably ship out tomorrow, you should see it by Friday.
Got my motor today nice living close, got it put back in and my o my this one runs better then the first one niceee I'm think the first one was a little weak from the start. Thanks viper team for a fast turnaround. :D |
I see the new motors on neobuggy. http://www.neobuggy.net/2013/07/26/n...ushless-motor/
I have 2 questions. How much $$$ and how much do they weigh. |

All motors 4 pole, sensored. 540 comes in 4000kv and 4500kv, 1/8 in 2100kv and 2700kv. Possibility of an 1800kv or 1900kv, if there is interest.

Viper R/C Solutions is proud to announce the release of the VF8 1/8 scale 4 pole electric motor. Over a year’s worth of development has gone into the VF8 to make it a smooth, durable power plant for racers and enthusiast around the world. Available in 3 options for 1/8 applications – VF8.19 (1900kv), VF8.21 (2100kv) and VF8.27 (2700kv) which were designed to work exclusively on 4s batteries. The high precision CNC-machined 6061 T6 billet aluminum can is ribbed for maximum cooling. Aluminum end bells secure oversized bearings and an epoxy balanced rotor designed for maximum performance. Designed for the rigors of and abuse of 1/8 competition, yet still lighter than other standard 1/8 motors. For added peace of mind, every VF8 motor is load tested at our factory before it leaves. To help ensure you have power on demand when you need it. Combined with the Viper’s VTX8 speed control the VF8 gives you the smoothest control and power available on the market. Not just simply designed to outperform – designed to be the new standard. Features ◾4-POLE/12-SLOT High performance design for 1/8 racing ◾Full aluminum design with CNC machined 6061 T6 ribbed can ◾Ultra low resistance high current soldering tabs ◾High precision ball bearing for maximum performance and life cycle ◾Maximized performance with VIPER VTX8 ESC ◾Factory limited 180-day warranty Specs Case Length 69.40mm 27.30in Case Diameter 41.80mm 1.65in Shaft Dimension 19x5mm Weight 317g 11.1oz Max Voltage VF8.27 2700KV 4S VF8.21 2100KV 4S VF8.19 1900KV 4S http://sphotos-a.ak.fbcdn.net/hphoto...05213972_n.png http://sphotos-b.ak.fbcdn.net/hphoto...12914395_n.png http://sphotos-d.ak.fbcdn.net/hphoto...15949368_n.jpg |
Told you guys we would tell ya :sneaky:
|
Will you be doing a combo to with the VTX8?
|
Love my Tekin Pro4 4000kV in my SCTE but I think my VTX8 would be happier with an "orange" motor. I guess I can pretend that they are orange.
|
Nice, ill get one of these when I need to replace a motor.
|
Think it is great that they are full black. Orange endbell may have been ok but really liking the full black - stealth :batman:
