I know it's a 540 unit but then there are 't' (turn?) Values, and then gearing to address, where do I start or do I buy a motor and a variety of pinions and just go out and figure? I JUST WANT A BIT OF SPEED!!! Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted February 17, 2023 Share Posted February 17, 2023 any idea whats in the car ? generally the lower the number of turns the faster the motor but less torque the esc should have a turn rating as well so dont go below that or the esc could pop 1 Quote Link to comment Share on other sites More sharing options...

I have a hobbywing quicrun 1060 esc, will try and find the spec and also see if I can identify the motor. Will get back to you tomorrow...

Fat Freddy Posted February 18, 2023 Share Posted February 18, 2023 (edited) As I understand it, the T value is the number of coils of wire around the rotor. Essentially the lighter the rotor (the fewer turns), the faster it can spin. Good for speed, but not for acceleration. More turns means more weight, so spins slower but generates more torque. I’d guess something like this would suit you https://www.modelsport.co.uk/product/core-rc-15t-silver-can-brushed-540-motor-442358 but that’s not a recommendation, just a suggestion, I’ve no personal experience of one of these.

Bajadre Posted February 18, 2023 Share Posted February 18, 2023 Spot on freddy also referred too as Turns the lower the turn the faster it spins more power, some motors have x too meaning torque like a 13x2 or 17x3 alot of drifter started to use the torquer motors to help with drifting good to bear in mind the lower the turn the quicker it will burn though the brushes though used to run a tt-01 on a no limit and 9turn motor and that thing flew lol nowadays brushless has taken over due to not need brushes inside its a dark art in racing with adjustabile timing to gain that extra omppph 😁 2 Quote Link to comment Share on other sites More sharing options...

If I want a bit of pace where do I start? look a read on here buddy they have a few gearing charts for that model 👍 best to pick your motor by the ESC allowance then do your gearing after by matching the right pinion and spur combo 👍 https://tamiyabase.com/forum/35-other-makes-custom-builds/10141-mardave-cobra-runner 2 Quote Link to comment Share on other sites More sharing options...

Steve-O2021 Posted February 18, 2023 Share Posted February 18, 2023 (edited) https://site.petitrc.com/Tech/RCCA_MotorTimingExplained/ Looks like your set to 15 Deg timing in the image you posted. There should be screws in the end bell bit that you can loosen and turn the end of it to adjust the timing.

Ahhh just thought if you tested it with the mechanical speedo at least you know it's not a setting on the esc. Oh your battery is 100% charged isn't it? Another thing you could do is strip the motor as it will be stripable and post some pics of the comm and brushes etc. Also check the bearings in the motor 1 Quote Link to comment Share on other sites More sharing options...

Stormbringer Posted February 18, 2023 Share Posted February 18, 2023 just checked and motor limits for esc are 2s 12 turn and 3s 18 turn https://www.modelsport.co.uk/product/hobbywing-quicrun-1060-brushed-waterproof-esc-sbec-404964 1 Quote Link to comment Share on other sites More sharing options...

Rustic Ade Posted February 18, 2023 Author Share Posted February 18, 2023 I need to sit down and consolidate all this brilliant info so I can read arrow down motor/suitable motor, battery, and gears. Thank you all for your time. Currently setting the kids up to built a micro crawler course in my roof space! 2 Quote Link to comment Share on other sites More sharing options...
Kpowell911 Posted February 18, 2023 Share Posted February 18, 2023 Id be more inclined to think your battery is the issure rather than the motor? 1 Quote Link to comment Share on other sites More sharing options...

Stormbringer Posted February 18, 2023 Share Posted February 18, 2023 (edited) basically its telling the esc what is full speed forward and back wards if you havnt set the endpoints the esc may not be not giving full throttle its in the manual how to do it Edited February 18, 2023 by Stormbringer 1 1 Quote Link to comment Share on other sites More sharing options...

They'll be back to their mum on Monday so will start fresh and uninterrupted them. Right, i'm going to wedge myself into the roof eves to play, ahem, hone my driving skills on the microcrawler track! Will let you know how Monday goes! Cheers 👍🏻 1 Quote Link to comment Share on other sites More sharing options...
