I'm new to the forum, I bought a blizzard fr, metal tracks, sabertooth esc, titan 380's, and spectrum receiver. I put everything together and its glitching bad. It's runs ok for a minute and then loses power and starts glitching out. I have all dip switches up except 2 and 3. I've tried adding a bec didn't help. I've tried different batteries 2s and 3s, both 5200mah. Nothing seems to work. What am I doing wrong? Thanks for any help. |

Hey Cody, what exactly is it doing when it's glitching? I tried the Titan 380s in mine with the sabertooth last year and the sabertooth didn't agree with them at all. Whenever I would try to go full throttle or give any fast acceleration the sabertooth would cut out and go into over current protection mode and heavily limit the throttle output whether running 2s or 3s.

That's pretty much what it's doing, it's cutting out and after running for a minute the motors get so hot it looses 90% power and will barely move, especially if trying to turn and go forward at the same time. I just don't understand how some guys run this setup and it works for them? |

Did you go to different motors? If so, what motors and did it fix the issues? Thanks for the help. |

I have heard lots of people have issues with the titans, some get lucky but it seems like most have issues, I think they are just drawing to many amps, the Sabertooth is a pretty small ESC in the end, only 12Amps. |

So is the solution to run a 370 motor? I've tried running the same setup with the stock motors and had the same issue. |

The stock motors in the blizzard are 370 size so the latrax 370 motors probably would have the same problem. I personally ditched the sabertooth esc and went with 2 hobbywing 1060 brushed ESCs. You would need a $4.00 V-tail mixer to control the steering on a standard pistol grip radio. If you have a higher end radio that can to the mixing for the motors, you wouldn't need the v tail mixer. My sabertooth did seem to handle the stock motors though so you may have some other problem with your setup. If I were you, I would go the the Hobbywing esc and a mixer, you have much more flexibility with them to run "hotter" motors that the sabertooth otherwise couldn't handle, such as the titans from my experience. Some people just don't have luck with the sabertooth esc due to its lower amp output.

Out of curiosity; has anybody tried one of the higher amp Sabertooths? |

I have a couple questions for you RC Master. I just ordered the same esc's as you, but I'm trying to figure out how to wire the mixer. Which mixer do I need and how do I set it up? Thanks for all your help! HOBBYWING RC Model V-Tail R/C Hobby Mixer for Flying Wings V-Tail airplanes https://www.amazon.com/dp/B013GF2BUC/ref=cm_sw_r_cp_api_1UhzybS5XWRJT (One of these?) Maxx Products V-Tail Mixer https://www.amazon.com/dp/B00BD4OUOY/ref=cm_sw_r_cp_api_pYhzyb7ZMEAWC (Or this one?) |

Your welcome, Go with the HobbyWing version, that is the same one I was using. HOBBYWING RC Model V-Tail R/C Hobby Mixer for Flying Wings V-Tail airplanes https://www.amazon.com/dp/B013GF2BUC/ref=cm_sw_r_cp_api_1UhzybS5XWRJT To hook up the ESCs remove or disconnect one of the middle (red / positive) wires from the receiver connector on one of the ESCs. (You never want to run two BECs together on the same receiver at the same time.) If you happen to be running an external BEC then disconnect both middle / positive wires from both ESCs. You don't need to disconnect any wires coming from the mixer. Then to connect the mixer, just connect both receiver leads to the receiver (CH1 and CH2 if using a pistol style radio), and connect the ESC receiver leads to the other female mixer connectors. I found it confusing figuring out which connector or receiver lead went to which CH on the receiver so you may just need to connect them up in different combinations until you get the snowcat to drive around properly. You may possibly need to reverse one of the channels on your radio as well. I hope this was clear enough for you, let us know how it goes! Edited by Rc Master, Dec 29 2016, 12:34 AM.

Thanks so much for all the info RC Master. I understand everything except how to connect 2 esc's to 1 plug on the mixer? Are you running both of the esc's wires together on the mixer? |

Actually it looks a bit deceiving, there are actually 2 plugs for both ESCs on the mixer. Looking at the picture it looks like there is only one plug, but the connectors are just stacked on top of each other. http://www.ebay.com/itm/Turnigy-V-Tail-Servo-Mixer-/172373251262?hash=item28223f14be:g:~fkAAOSwstxU9mDJ If you take a look at the pictures on this ebay listing, you can see both connectors. It just looks like one plug depending on which position the picture was taken. Edited by Rc Master, Dec 29 2016, 12:08 PM.

RC Master, that makes a lot more sense! Thanks for answering all my questions. All my parts should be here in a week or so. I live in Alaska and we are getting a lot of snow, I'm excited to get out and play! |

My Hobbywing 1060 esc's, vtail mixer, titan 380's and 15T pinions came in. We hooked everything up and I ran for 1 1/2 hours on 3s. The motors were super hot. I was running with metal tracks and F/B/R on both esc's. today I switched to plastic tracks, 2s and running F/R on esc's. it is 100% better, motors stay cool to the touch, way easier to control without the brake setting on, and a lot less resistance then the metal tracks. I would like to run my metal tracks so I'm thinking of looking for a 35T motor to run. I'm loving this setup though! Thank y'all for your help! |
