Lukevernon Posted April 6, 2023 Share Posted April 6, 2023 Can anyone suggest an esc that will actually run this motor. The one it came with as a combo set on fire. It’s going in a tt-02 Quote Link to comment Share on other sites More sharing options...
Bajadre Posted April 7, 2023 Share Posted April 7, 2023 doesnt sound good brother what gearing are you using on the TT? the esc should be matched to that motor so shouldnt have burnt up could be either overgeared or bad soldering etc Quote Link to comment Share on other sites More sharing options...
Lukevernon Posted April 7, 2023 Author Share Posted April 7, 2023 The esc that was paired was a quicrun 10bl120 and the gearing is what comes stock in the tt Quote Link to comment Share on other sites More sharing options...
Nitroholic Posted April 7, 2023 Share Posted April 7, 2023 You are on the edge of specs for the ESC, and as long as you were just using 2S Lipo, it should be able to take it. Just NOT if it's geared wrong. Your car is geared for a brushed silver can basic motor running on NiMh ..... The chances of being able to go that far away from stock on motor/ESC and NOT have to change the gearing are pretty small. There are some overall reduction ratios suggested on the Hobbywing website for the ESC you had. https://www.hobbywingdirect.com/products/quicrun-10bl120-esc?variant=2139725987868 Shows how much the ratio changed from a 23T motor....to a 6.5T motor. You have gone further than that. Needs a much lower geared setup or your motor pulls too many amps, and the ESC smokes. Geared correctly, your motor should probably pull around 50A tops, and should work well with a 120A ESC. But you have to gear it right. 3 Quote Link to comment Share on other sites More sharing options...
Lukevernon Posted April 7, 2023 Author Share Posted April 7, 2023 Would an 18 tooth spur make it work? Quote Link to comment Share on other sites More sharing options...
Nitroholic Posted April 7, 2023 Share Posted April 7, 2023 How long is you're piece of string ..... I don;t know what spur you have now, what pinion or what your diff reduction is. Gearing is something you need to work out from anumber of variables. 1 Quote Link to comment Share on other sites More sharing options...
Bajadre Posted April 8, 2023 Share Posted April 8, 2023 says the stocking gearing is 22t pinion and 70t spur online it would help dropping to a 18t pinion luke but tbh that combo and kv seems waaay to high for a 1/10 onroad car should be looking around 3000kv to 4000kv tbh back in the day i ran a tt-01 on a 11turn motor and no limit esc and that thing was stupid rapid lol 50mph Quote Link to comment Share on other sites More sharing options...
Kpowell911 Posted April 9, 2023 Share Posted April 9, 2023 Ideally you dont want a 3.5T motor in a TT02. Its far too low a kv. Youd need to maybe get the adjustable gear mount and gear it as low as you can Quote Link to comment Share on other sites More sharing options...
