SWF Posted July 17, 2021 Share Posted July 17, 2021 Hi I have converted my emb-MT to a truggy, well with MT front bumper and rear wing, so nearly. I planned on fitting the 2850 4500kv motor that the t comes with, but have had difficulty finding one? Can anybody recommend an alternative motor/esc, along with suggested Kv rating and pinion size, running 2s 35c batteries. While I’m here, what oil is recommended for the shocks, currently have 30wt front and rear? Cheers Steve Quote Link to comment Share on other sites More sharing options...
Alex97 Posted July 17, 2021 Share Posted July 17, 2021 Racestar 2845 motora from bangood, they are about £11 and are pretty good. 4000kv would be nice however I had the 5900kv and it flew! Quote Link to comment Share on other sites More sharing options...
SWF Posted July 17, 2021 Author Share Posted July 17, 2021 Hi Alex Thanks for the suggestion. Did the 5900kv need an upgrade to the esc, or is the 35a OK with that? Cheers Quote Link to comment Share on other sites More sharing options...

Cheers I was running a 60a ESC but I believe temps weren't an issue but can't recal. You might be ok. Quote Link to comment Share on other sites More sharing options...
SWF Posted July 17, 2021 Author Share Posted July 17, 2021 I’ll look for a 60a esc that is small enough to fit and get a Racestar. Thanks Again Quote Link to comment Share on other sites More sharing options...

BigGinge Posted July 17, 2021 Share Posted July 17, 2021 I’ve put a surpass platinum 2845 in mine; I e only gone for a 3100kv one as I’m not trying to hit big numbers in speed runs but you can get them in a pretty wide range of ratings. https://a.aliexpress.com/_mqrpfu1 Still haven’t actually run it though, so it’s possible it may just explode rather than going anywhere.

SWF Posted July 17, 2021 Author Share Posted July 17, 2021 (edited) Surpass platinum looks the part for a combo! Am I correct that the pinions are mod 0.5? Here is a picture of mine. Speed is fine, but a little extra acceleration is what it needs. Edited October 31, 2023 by SWF Quote Link to comment Share on other sites More sharing options...

The 18 tooth pinion in my kit measures about 9.5 mm across which puts it pretty close to a 0.5 pitch according to this calculator: https://www.radiocontrolinfo.com/information/rc-calculators/rc-gear-calculator/ Quote Link to comment Share on other sites More sharing options...

The Truggy uses a longer chassis, top deck, side guards and centre drive shaft than the MT, so you need to swap those out as well. There is a kit you can get which has all the bits you need in it. https://shop.lcracing.net/products/l6213?variant=30298914521201 edit: if you’re going from the MT then the kit is missing the wing mount and bumpers so there would be a few extra bits you need to pick up.

SWF Posted November 27, 2021 Author Share Posted November 27, 2021 Hi As BigGinge says, just rear wing, mount and bumpers, on top of conversion kit. I’ve left the MT front bumper on mine though. If you want to do a complete job, you also need a 2850 motor and an 18 tooth pinion. I bought a Surpass Platinum 2848 4300k for about £12 from AliExpress for mine. I think it would be fine with a 19 pinion as it runs cool, but might need a more powerful ESC then too? Best of luck! Steve Quote Link to comment Share on other sites More sharing options...

Steve i am getting the pro truggy version and already got the mt wheels, so i thought since i have the wheels already then i was thinking what is needed to change to mt. 1 Quote Link to comment Share on other sites More sharing options...

SWF Posted November 27, 2021 Author Share Posted November 27, 2021 (edited) Hi froggy8 Whoops, sounds like I’ve got it the wrong way around? Truggy to MT would be short chassis, centre shaft, top deck, bumpers, rear body mounts and body shell. I’m not sure there is space for the truggy 50mm motor on the short chassis, as I converted from MT to truggy? Is that what you were after? It was an easy conversion, they are great as either truggy or MT. Cheers Steve Edited November 27, 2021 by SWF Rear body mounts 2 Quote Link to comment Share on other sites More sharing options...

froggy8 Posted November 28, 2021 Share Posted November 28, 2021 hey @SWF been looking at your truggy and @BigGinge . you both have got the mt wheels, i am guessing you had to gear it down slightly to compensate the size of the wheels?

SWF Posted November 28, 2021 Author Share Posted November 28, 2021 Hi Mine started as an MT and had a 17 tooth pinion, which is still fitted to “your” motor. The MT and Truggy wheels are similar in diameter, so no need to compensate with gearing. I now have an 18 tooth pinion fitted, standard for the Truggy I think, as my motor is 4370kv, slightly lower than the 4500kv your Pro will have. I’m still running the standard 35a esc, so might upgrade to a 60a and 19 tooth at some stage, or go 3s rather than my current 2s? Choices, choices! Cheers Steve 1 Quote Link to comment Share on other sites More sharing options...

Cheers Steve thank you for that 🙂 which esc you thinking of getting? the hobbywing one? on one of my truggy, i have a 35a too but i will see if its fast enough on 2s first before i start upgrading the esc. i could get a smaller spur and bigger pinion, that would make it go faster without upgrading the esc.

BigGinge Posted November 28, 2021 Share Posted November 28, 2021 I think mine is very conservative in it’s gearing as it’s still fitted with a 19 tooth pinion and the 3100 KV motor at the moment. Having said that this seems to run very nicely on 3S with the smaller 30/35A hobby wing esc without anything getting too hot. It also lets me hand it over to the five year old when it’s running 2S without worrying too much about him sending it straight into my shins. 1 Quote Link to comment Share on other sites More sharing options...
SWF Posted November 28, 2021 Author Share Posted November 28, 2021 Hi I am thinking about Hobbywing Max 10, as it’s smaller than most of the cheaper options, though is not going to work on 3s with the 4370kv motor. The Hobbywing 10bl60 has better motor kv rating but is physically much larger. I might buy a 3s battery and try that first, 1/3rd the price of an esc too. The standard gearing is about right for the standard electronics, 35a esc/4500kv motor, you might start to run hot on 2s if you gear up too much. With the standard 35a esc, using standard or lower gearing with 3s would be the best way to go for speed, I think. Cheers Quote Link to comment Share on other sites More sharing options...
