Mark_C Posted July 9, 2020 Share Posted July 9, 2020 Has anyone used these ? Modelsport sell them so assume they can't be complete junk but can't find much about them. Obviously chinese, but what isn't these days https://smddirect.co.uk/collections/smd-brushless-combos/products/jbr365039c-v2-brushless-combo-3900kv-60amp-esc Any other suggestions for an inexpensive 3S combo ? Was thinking about Gool but seems the ESCs commonly have stuttering issues and saw a picture of one the other day that decided to set fire to itself, so not keen... Going in an on-road car. Thanks!

Russ528 Posted July 10, 2020 Share Posted July 10, 2020 I installed the 3900 on mine this week, and to be fair, runs fine, build quality looks good, programs fine, seems good to me. Quote Link to comment Share on other sites More sharing options...
Garry Posted July 10, 2020 Share Posted July 10, 2020 They are a great upgrade to a lot of ESCs which come in RTR cars, UK based too. Quote Link to comment Share on other sites More sharing options...
fnknan Posted July 10, 2020 Share Posted July 10, 2020 Looks the same as the surpass hobby 60amp systems which are a lot cheaper. 2 Quote Link to comment Share on other sites More sharing options...
Mark_C Posted July 10, 2020 Author Share Posted July 10, 2020 Thanks for all the replies. I'll check out surpass. Quote Link to comment Share on other sites More sharing options...
Russ528 Posted July 12, 2020 Share Posted July 12, 2020 (edited) A little addition to this. Turned the car on last night (just tinkering with the radio trims, etc) and noticed the ESC fan making a racket. Sounded like the fan blades were catching on something, but there's nothing in there (and the car's only been run up and down the road twice this week since I installed it!). It then stopped completely. I gave it a little prod to see if it was jammed - which it wasn't, and started spinning/clacking round a few times again, then stopped. Contacted SMD last night as the thing is less than a week old and has had probably 20 mins tops run time. Had another look this morning in the sunlight, and one of the fan blades has partially torn away from the centre of the fan, and the tip has been catching the fan guard on the top, and gradually tearing it more. I've managed to tweak it down, but doubt it'll stay put for very long. Edited July 12, 2020 by Russ528 Quote Link to comment Share on other sites More sharing options...
Alex97 Posted July 12, 2020 Share Posted July 12, 2020 Just because Modelsport sell it doesn't mean it's any good! 2 Quote Link to comment Share on other sites More sharing options...
Russ528 Posted July 13, 2020 Share Posted July 13, 2020 Jamie @ SMD is sending me a replacement ESC, so not all bad news! Quote Link to comment Share on other sites More sharing options...
Rien232 Posted January 22, 2023 Share Posted January 22, 2023 What about the speed on these things any good? Just looking for a brushless esc and motor under 100 wondering if these will be any good for a TT01e Quote Link to comment Share on other sites More sharing options...

Id go for this though https://www.modelsport.co.uk/product/hobbywing-ezrun-combo-max10-3652sl-4000kv-brushless-motor-420923 do you have a bearing kit for your TT01?

Rien232 Posted January 23, 2023 Share Posted January 23, 2023 Yes I have a bearing kit just one question does the hobby wing come ready to run no soldering required? Quote Link to comment Share on other sites More sharing options...
Rien232 Posted January 23, 2023 Share Posted January 23, 2023 Also I was going for the 3900kv motor choice Quote Link to comment Share on other sites More sharing options...

Kpowell911 Posted January 23, 2023 Share Posted January 23, 2023 You will need to solder a battery connector on, but modelsport give you the option for them to do it for you. It depends what battery connector you have. Yes Ive used probably 30 Hobbywing systems over the years Quote Link to comment Share on other sites More sharing options...

Yea, then install it, and program it. You may need to look at changing the gearing, but Im not sure what pinion youd need in a TT01 Quote Link to comment Share on other sites More sharing options...

Youll just need to check what gear ratio you need for a brushless system as it may be different to brushed. It should be same motor shaft diameter as it says ‘standard 1/10th’ Quote Link to comment Share on other sites More sharing options...

Kpowell911 Posted January 23, 2023 Share Posted January 23, 2023 (edited) You dont need to post so many times. Bearings and metal shafts are what Id advise for a brushless TT01. Ive had several brushless TT01/2s over the years yes. I am also a big fan of Hobbywing stuff I also recently build a budget build Cosworth Edited January 23, 2023 by Kpowell911 Quote Link to comment Share on other sites More sharing options...
